Yes / Non-communicable diseases (NCDs) affect a growing share of the population in Kosovo. The country faces challenges with NCDs management, specifically detecting, screening, and treating people with NCDs. To assess the management of NCDs, including the inputs that influence the provision of NCDs and outcomes of NCD management. Eligibility criteria: Studies had to report NCD management in Kosovo. Sources of evidence: We systematically searched Google Scholar, PubMed, Scopus, and Web of Science. Charting methods: The data were charted by two researchers. We extracted data on general study details and design and information on the management and outcomes of NCDs in Kosovo. Synthesis of results: For the mix of studies that were included in the review, thematic narrative synthesis was used. We developed a conceptual framework based on health production core components to analyze the data. Results: Kosovo's health care system is available to provide basic care for patients with NCDs. However, there are serious limitations in the availability of key inputs providing care, i.e., funding, medicines, supplies, and medical staff. Additionally, in terms of the management of NCDs, there are areas for improvement, such as limited application of clinical pathways and guidelines and issues with referrals of patients among levels and sectors of care. Finally, it is worth noting that there is overall limited information on NCD management and outcomes. Conclusions: Kosovo provides only basic services and treatment of NCDs. The data reporting the existing situation on NCD management are limited. The inputs from this review are helpful for existing policy efforts by the government aimed to enhance NCD care in Kosovo. / This study is part of the research done for a World Bank review of the state of NCDs in Kosovo and APC was funded through the Access Accelerated Trust Fund (P170638).

A infecção por papilomavirus é a principal causa de desenvolvimento de neoplasias intraepiteliais cervicais (NIC) e câncer do colo do útero (CCU). Estudos epidemiológicos têm demonstrado que a persistência do genoma viral encontra-se associado a variantes moleculares específicas de papilomavirus humano (HPV) de alto risco. As moléculas HLA de classe II têm um importante papel na resposta imune. Associações entre HLA e CCU ou infecção por HPV tem sido demonstrado em diferentes populações. O nosso objetivo foi verificar se a variabilidade de HLA-DRB1 e DQB1 estavam associada ao CCU e NIC III em mulheres de Belém, uma população formada pelos 3 principais grupos étnicos humanos e uma área de alto risco para o CCU no Norte do Brasil. Foi investigada a existência de diferenças na distribuição de alelos HLA entre mulheres com CCU e NIC III portadoras de diferentes variantes de HPV-16 e mulheres citologicamente normais. Os genes HLA DQB1 e DRB1 foram tipados pelo método de PCR-SSO em 95 casos e 287 controles de mulheres com citologia normal atendidas em um centro de prevenção do colo do útero na mesma cidade. As variantes de HPV-16 foram tipadas por sequenciamento de um fragmento da região controladora do genoma viral (LCR). O polimorfismo na posição 350 do gene E6 foi tipado baseado em um protocolo de hibridização em pontos, para identificar a alteração na posição 350T→G. A magnitude das associações foi estimada por odds ratio (OR) e os respectivos intervalos de confiança (IC), ajustados para potenciais fatores de confusão. Uma associação positiva foi observada entre CCU e os haplótipos DRB1* 150 l-DQB1*0602, DRB1*04-DQB1*0301 e DRB1*1602-DQB1*0301. Ao contrário, DRB1*01-DQB1*0501 mostrou um efeito protetor. Os alelos DRB1*0804, DQB1*0402 apresentaram efeito protetor contra positividade por HPV. O alelo DQB1*0502 e o grupo DRB1*15 foram positivamente associados. Os nossos resultados mostram que as associações positivas de DRB1*1501 e DRB1*1602 podem ser atribuídas a variantes asiático-americanas quando comparado a variantes européias. O risco conferido a DRB1*1501 foi encontrado associado tanto a variantes E6350G quanto a variantes E6350T, entretanto, o maior efeito foi devido às variantes E6250T. A associação positiva de DRB1*1602 foi significativa somente no grupo de mulheres positivas para E6350G. Estes resultados estão de acordo com a composição étnica da população estudada bem como um maior potencial oncogênico de certas variantes. Nossos dados sugerem que a contribuição dos alelos HLA na susceptibilidade genética ao CCU difere de acordo com a distribuição das variantes de HPV em uma dada região geográfica ou grupo étnico. / Papillomavirus infection is the major cause for the development of cervical intraepithelial neoplasia (CIN) and invasive cervical cancer (ICC) in humano Epidemiological studies have demonstrated that persistence of the viral genome and development of cervical cancer are associated with specific molecular variants of high-risk human Papillomavirus (HPV). Human leukocyte antigen (HLA) molecules play a role in immune response and associations between HLA and IeC or HPV infections have been reported in several populations. We aimed to verify if HLA-DRB1 and DQB1 variability is related to ICC and CIN III in women from Belem, a population formed by the three main human ethnic groups and a high-risk area for this disease in Northem Brazil. We also investigated if there are differences in the HLA class II alleles distribution between women with ICC and CIN III that harbor different HPV-16 variants and women without cancer. HLA DRB1 and DQB1 were typed by PCR-SSO based methods in 95 ICC cases and 287 controls consisting of normal cytology from women attending cervical cancer screening programs in the same city. HPV-16 variants were typed by sequencing a PCR-amplified fragment of long control region (LCR) of the viral genome. The E6350 polymorphism was typed on the basis of a dot blot protocol targeting a specific nucleotide alteration in the position 350T→G of the E6 gene. The magnitude of associations was estimated by odds ratio (OR) and the respective 95% confidence interval (CI), adjusted for potential confounder factors. A positive association was found between ICC cases and DRB1*150 l-DQB1*0602, DRB1*04-DQB1*0301 and DRB1*1602-DQB1*0301 haplotypes. Conversely, DRB1*01-DQB1*05 showed a protective effect. DRB1*0804, DQB1*0402 showed negative association against HPV infection. DQB1*0502 and DRB1*15 were positively associated with HPV infection. Our study showed that positive association of DRB1*1501 and DRB1*1602 alleles may be attributed to AsianAmerican then European variants. Furthermore, the DRB1*1501 was found associated with both women carrying E6350G or E350T, however, a higher effect was observed for E6350T variants carriers. The positive association of DRB1*1602 was significant for women harboring E6350G then E6350T variants. These data are in agreement with ethnical component of the studied population as well as a higher oncogenic potential of certain HPV variants. Our results also suggest that the contribution of HLA class II alieles to the genetic susceptibility to ICC differs depending on the HPV-16 variants distribution in a given geographic and ethnic group.

Neste estudo, foram abordados os aspectos quantitativos do gânglio cervical cranial (GCC) esquerdo de preás (Galea spixii spixii) machos, oriundos do criatório da Universidade Federal Rural do Semi-Árido Nordestino de Mossoró-RN. Os seguintes parâmetros foram estimados: volume do GCC, número total e tamanho dos neurônios (uni e binucleados) durante dois períodos do desenvolvimento pós-natal (maturação e envelhecimento). Para tanto, utilizamos quatro grupos etários distintos de animais: neonatos, jovens, adultos e senis. Após a eutanásia dos animais, os GCCs foram fixados (perfusão sistêmica) com solução de formoldeído (4%) em PBS, embebidos em solução de ágar (10%) e seccionados sistemática, uniforme e aleatoriamente, aplicando-se o princípio de amostragem e contagem do fractionator. Os principais resultados desta pesquisa foram: houve diferença significativa entre os grupos etários para os parâmetros: Peso Neonato: 0,00056 ; Jovem: 0,00084; Adulto: 0,00116; Senil: 0,00118. Comprimento Neonato: 1,294 ; Jovem: 2,076; Adulto: 2,304; Senil: 2,082. Largura Neonato: 0,842; Jovem: 1,028; Adulto: 1,062; Senil: 1,174. Volume ganglionar Neonato: 0,34 mm3 ; Jovem: 0,30 mm3; Adulto: 0,39 mm3; Senil: 0,63 mm3 e Volume neuronal médio de neurônios uninucleados Neonato: 2916,90 mm3; Jovem: 3550,00 mm3; Adulto: 7409,00 mm3; Senil: 6701,00 mm3. As principais conclusões deste estudo foram: (i) peso, comprimento e largura do GCC apresentaram aumento significativo de 185%, 60% e 79% respectivamente, durante o período de maturação, enquanto durante o período de envelhecimento, o peso do GCC apresentou queda de 33%, o comprimento um pequeno decréscimo de 10%, entretanto a largura, durante este mesmo período, apresentou um aumento progressivo de mais de 10%, tais alterações relacionadas com a idade refletiram no volume ganglionar, causando hipertrofia; (ii) Essa hipertrofia do GCC de preás é secundária ao desenvolvimento pós-natal (maturação e envelhecimento), aumentando em 85%, acompanhado por um aumento alométrico, da ordem de 6 vezes em relação à massa corporal, aproximadamente 622%; (iii) Há hipertrofia dos neurônios uninucleados que é secundária ao desenvolvimento pós-natal do GCC de preás, aumentando em 154% durante o período de maturação com uma pequena queda de 10% durante o envelhecimento. Finalmente, sugere-se que estudos futuros possam investigar se o tamanho dos territórios de inervação destes gânglios pode desencadear mudanças na micro e macroestrutura dos mesmos, incluindo a possibilidade de ocorrência de neurogênese, que seria estudada por meio de imunomarcadores específicos. / This study aimed at detecting whether post-natal development would exert any effect on the size and number of cranial cervical ganglion (CCG) neurons of male preas (Galea spixii spixii). Twenty left CCGs from twenty preas were harvested from the Animal Facility of the Universidade Federal Rural do Semi-Árido Nordestino, Mossoró- RN and were divided into four different age groups: newborn, young, adult and aged subjects. The following parameters were estimated using Cavalieri\'s principle and optical fractionator and planar rotator , respectively: the volume of CCG, total number and mean volume of uni and binucleate neurons. After euthanasia, the CCGs were perfusion-fixed with a 4% formaldehyde solution in PBS, agar-embedded and, SUR vibrosectioned. The ganglion volume was 0.34 mm3 (newborn), 0.30 mm3 (young), 0.39 mm3 (adult) and 0.63 mm3 (aged animals) (p= 0,012). The mean volume of uninucleate neurons was 2,917 mm3 (newborn), 3,550 mm3 (young), 7,409 mm3 (adult) and 6,701 mm3 (aged animals) (p=0,0001). The main conclusions of this study were: (i) The CCG hypertrophy - 85% - is the result of post-natal development (maturation and ageing), (ii) a 154% increase (hypertrophy) in the volume of uninucleate neurons during the maturation is followed by a 10% atrophy of them during ageing. Future studies may investigate whether the size of the CCG\'s target-organs can affect the structural foundation of CCG and, therefore, add further fuel to the notion that a post-natal neurogenesis may indeed exist in sympathetic ganglia.

O presente estudo analizou nove gânglios cervicais craniais esquerdos (GCC) de Cutias (Dasyprocta aguti) machos oriundos do criatório da Universidade Federal Rural do Semi Árido Nordestino de Mossoró- RN. Nestes animais foi estimado o número total dos neurônios (mono e binucleados), bem como seus volumes, volume do gânglio, a densidade neuronal e densidade de volume neuronal durante o desenvolvimento pós-natal (maturação): animais neonatos, jovens e adultos. Os GCCs foram fixados com solução de formoldeído (4%) em PBS, embebidos em solução de ágar e seccionados sistemática, uniforme e aleatoriamente para a aplicação dos métodos estereológicos entre os quais disector e rotator ópticos. para a estimativa da densidade e do volume neuronal, respectivamente. Houve diferença significativa entre os grupos etários para os parâmetros: volume ganglionar, número total de neurônios binucleados, volume neuronal médio de neuronios mono e binucleados e densidade de volume neuronal. A conclusão é de que a idade influencia quantitativamente a dinamica neuronal do GCC de cutias e futuramente estes dados servirão como base para a investigação da ocorrência de divisão celular durante o período pós-natal em roedores. / The present study was pursued in nine left cranial cervical ganglia (CCG) of male cutias (Dasyprocta aguti) obtained from the animal house of the Universidade Federal Rural do Semi-Árido Nordestina em Mossoró- RN. The number of CCG neurons as well as their volume, ganglion volume, numerical density and neuronal volume density were estimated during the post-natal development (maturation), in neonates, young and adult animals, by using 3-D design-based stereological methods, e.g., optical disector and optical rotator. Briefly, CCGs were fixed with a 4% formaldehyde solution in PBS, embedded in a 10% agar solution and exhaustively vibrosectioned (SURS) in order to accordingly perform the relevant stereological estimations. There were significant difference between age groups for the follow parameters: ganglion volume, total number of binucleated neurons, mean neuronal volume of mono and binucleated neurons and volume density of neurons. The conclusion is of that the age quantitative influences the dinamic of neuronal cells of the GCC of agoutis. In the future these data will serve as basis for the inquiry of the occurrence of cellular division during the post-natal period in rodents.

Esta tese de Doutorado apresenta três estudos in vitro independentes. Na parte 1, avaliou-se a permeabilidade dentinária após tratamentos dessensibilizantes de consultório e a resistência destes à ciclagem erosiva-abrasiva de 5 dias; na parte 2, avaliou-se a permeabilidade dentinária após aplicação de cremes dentais dessensibilizantes e/ou anti-erosivos durante uma ciclagem erosiva-abrasiva de 5 dias; e na parte 3, avaliou-se a perda de superfície dentinária resultante da utilização dos cremes dentais dessensibilizantes e/ou anti-erosivos em um modelo de ciclagem erosiva-abrasiva inicial. Nas partes 1 e 2 os túbulos dentinários dos espécimes de dentina foram abertos com solução de EDTA e a permeabilidade máxima inicial foi analisada (considerada 100%). Na parte 1, os tratamentos dessensibilizantes de consultório foram realizados e a permeabilidade dentinária reavaliada (%Lp-após tratamento). Em ambos estudos, os espécimes passaram por uma ciclagem erosivaabrasiva de 5 dias. Cada dia consistiu em 4 imersões em ácido cítrico (2 min, 1%, pH ~2,6), com exposição à saliva humana clarificada por 60 min entre os desafios erosivos. Trinta minutos após o primeiro e último desafios erosivos, os espécimes foram escovados em máquina de escovação (2 N, 45 ciclos) totalizando 2 minutos de exposição às suspensões formadas por creme dental e saliva humana. Na parte 1, foi utilizado um creme dental fluoretado convencional para todos os grupos e na parte 2, cremes dentais de acordo com cada grupo. Ao final dos 5 dias de ciclagem, a permeabilidade dentinária final (%Lp-após ciclagem) foi avaliada. Os mesmos cremes dentais testados na parte 2 também foram testados quanto à perda de superfície (PS) na parte 3. Para isso, os espécimes tiveram duas partes das superfícies protegidas com uma fita adesiva de forma a deixar uma área central exposta e, então, foram submetidos a 5 ciclos de erosão-abrasão iniciais. Em cada ciclo os espécimes foram imersos em saliva artificial (60 minutos; pH 7), e em ácido cítrico (3 minutos; 1%; pH 3,6). Então, os espécimes foram escovados em máquina de escovação (2 N; 25 ciclos) com as suspensões formadas pela mistura dos cremes dentais com saliva artificial, totalizando 2 minutos de exposição às suspensões. Para cada estudo, os dados de %Lp e PS foram estatisticamente analisados. Parte 1: Os grupos NUPRO e Gluma Desensitizer foram os únicos que apresentaram menor %Lp quando comparados com controle negativo (p=0,026 e p=0,022; respectivamente), em ambos os tempos analisados. Parte 2: Os cremes dentais Regenerate e Sensodyne Pronamel apresentaram menor %Lp em comparação com o grupo controle negativo (p<0,05). Parte 3: Os grupos apresentaram diferentes graus de PS independente da indicação comercial, sendo o Elmex Erosion Protection, o único grupo com baixa PS que se diferenciou do controle positivo (p=0,031). Pode-se concluir que os tratamentos de consultório NUPRO e Gluma Desensitizer e os cremes dentais Regenerate e Sensodyne Pronamel foram os melhores em diminuir a %Lp, no modelo estudado. Em relação à PS, em um modelo de ciclagem erosiva-abrasiva inicial, os cremes dentais apresentaram diferentes graus de PS, independente da indicação comercial, tendo o Elmex Erosion Protection mostrado o resultado mais promissor. / This PhD thesis presents three independent in vitro studies. At part 1, dentine permeability was evaluated after in-office desensitizing treatments and their resistance to an erosive-abrasive cycling of 5 days; at part 2, dentine permeability was evaluated after application of desensitizing and/or anti-erosive toothpastes during an erosive-abrasive cycling of 5-day; and at part 3, dentine surface loss resulting from the use of desensitizing and/or anti-erosive toothpastes in an initial erosive-abrasive cycling model was evaluated. At parts 1 and 2 the dentinal tubules were opened with EDTA solution and the initial maximum permeability was analyzed (considered 100%). At part 1, the in-office desensitizing treatments were performed and the dentine permeability was reevaluated (%Lp-after treatment). In both studies, the specimens underwent a 5-day erosive-abrasive cycling. Each day consisted of 4 immersions in citric acid (2 minutes, 1%, pH ~ 2.6), and exposure to clarified human saliva for 60 minutes between the erosive challenges. Thirty minutes after the first and the last erosive challenge, the specimens were brushed in a brushing machine (2 N, 45 cycles) totalizing 2 minutes of exposure to the slurries formed by the mixture of toothpaste and human saliva. At part 1, a regular fluoride toothpaste was used for all groups and at part 2, the toothpastes were used according to each group. After the 5 days of cycling, the final dentine permeability (%Lp-after cycling) was evaluated. The same toothpastes tested at part 2 were also analyzed for surface loss (SL) at part 3. For this, the specimens had two parts of the surfaces protected with an adhesive tape leaving a central area exposed, and then were submitted to 5 cycles of initial erosion-abrasion. In each cycle, the specimens were immersed in artificial saliva (60 minutes, pH 7) and in citric acid (3 minutes, 1%, pH 3.6). Then, the specimens were brushed in a brushing machine (2 N, 25 cycles) with the slurries formed by the mixture of the toothpastes with artificial saliva, also totalizing 2 minutes of exposure to the slurries. For each study, the data of %Lp and SL were statistically analyzed. Part 1: The groups NUPRO and Gluma Desensitizer were the only ones that presented lower %Lp when compared to the negative control (p=0.026 and p=0.022, respectively), at both periods analyzed. Part 2: Regenerate and Sensodyne Pronamel toothpastes presented lower %Lp compared to the negative control group (p<0.05). Part 3: The groups showed different degrees of SL regardless of the claim of the toothpaste. Elmex Erosion Protection was the only group with low SL that differed from the positive control (p=0.031). It can be concluded that the in-office treatments NUPRO and Gluma Desensitizer, and the toothpastes Regenerate and Sensodyne Pronamel were able to significantly reduce the %Lp, in the model studied. Considering the SL, analyzed with an initial erosive-abrasive cycling model, toothpastes presented different degrees of SL, regardless of their claim, and Elmex Erosion Protection showed the most promising results.

Introdução - A perda de estrutura dental devido às lesões cervicais não cariosas (LCNC) é um evento clínico recorrente e amplamente discutido na literatura. Os fatores etiológicos relacionados a esse tipo de lesão são: abrasão, erosão e abfração. Segundo vários autores, a particular disposição das estruturas dentinárias torna-se ainda mais interessante e curiosa quando se observa a dentina nas regiões com LCNC. Objetivos - A proposta deste trabalho foi estudar, comparativamente, em microscópio eletrônico de varredura (M.E.V.), a microestrutura dentinária de LCNC, a partir de dentes extraídos e armazenados sob condições controladas, considerando-se o método de preparação dos espécimes. Também se propôs a comparar o conteúdo intratubular da dentina com LCNC com sua contraparte lingual, sem lesão, e observar se a presença de estruturas intratubulares (EIT) tem relação com a ocorrência de hiperestesia dentinária (HD). Materiais e Métodos - Utilizaram-se as superfícies vestibulares e linguais homólogas de 14 dentes humanos, portadores de LCNC, extraídos por razões terapêuticas, e imediatamente fixados em Karnovsky. Os dentes foram divididos em 3 grupos, cada um deles subdivido em dois subgrupos, de acordo com o tratamento dos espécimes. Amostras da região da lesão e suas contrapartes linguais foram, então, pós-fixadas segundo protocolo apropriado para M.E.V. Tanto a superfície da lesão, quanto as estruturas dentinárias subjacentes foram estudadas obedecendo à seguinte seqüência: Grupo I - amostras da lesão seccionadas com disco, subdivididas em: Grupo IA - limpeza com ultra-som por 15 minutos; Grupo IB - limpeza com ultra-som por 15 minutos, seguida de condicionamento com H3PO4 a 5%, por 15 segundos. Grupos II - amostras fraturadas, subdivididas em: Grupo IIA - limpeza com ultra-som por 30 minutos; Grupo IIB - apenas condicionamento com H3PO4 a 5%, por 15 segundos; e Grupo III - amostras fraturadas e assim subdivididas: Grupo IIIA - controle, sem qualquer tipo de tratamento; Grupo IIIB - imersão dos espécimes em NaOCl a 2%, por 5 minutos. Os espécimes foram desidratados, submetidos a secagem em ponto crítico e metalizados com ouro para análise em M.E.V. Resultados - 1 - De maneira geral, todos os métodos interferem, em maior ou menor proporção, com a natureza dos espécimes. Na superfície da lesão, o método que melhor permitiu a visualização das estruturas dentinárias foi o ultra-som seguido do condicionamento ácido (Grupo IIA). Entretanto, é o procedimento que mais altera a estrutura da dentina. Na dentina abaixo da lesão, o método de observação mais apropriado foi o da simples fratura controle (Grupo IIIA). 2 - Tanto a dentina correspondente à região da lesão, quanto à da região não lesionada lingual, apresentaram conteúdos intratubulares semelhantes. 3 ? Não foram notadas diferenças estruturais nas lesões hipersensíveis em comparação com aquelas não-sensíveis. Conclusões - Os métodos de preparação dos espécimes tendem, em maior ou menor extensão, a alterar a natureza do que está sendo observado. Não se pode afirmar, à luz da metodologia empregada, que a existência de EIT é ocorrência particular da dentina em LCNC. Aparentemente, as EITs ocorrem tanto na dentina que apresenta HD como naquela não sensível. / Introduction - The lost of dental structure because of non carious cervical lesion is one of the most important clinical event discussed in dental literature. The most important etiologic factors related to this type of lesions are: abrasion, erosion and abfraction. According to many authors, this particular lost of dental structures became more interesting and curious when the dentin in regions with NCCL is study microscopically. Objectives - The purpose of this investigation was to study, comparatively, in scanning electronic microscopy (S.E.M.), the dental microstructure of NCCL and lesion-dentin dentin surfaces. The null hypothesis were the following: 1- the methods used for specimens preparations lead to different changes on dentin microstructures; 2- there is no difference between NCCL dentin microstructure and that from lesion-free dentin in the same tooth; 3- ITS can be found both in hypersensitive and non-sensitive dentin. Materials and Method - Dentin samples from buccal and lingual surfaces of 14 extracted human teeth, with NCCL on buccal surface, were used. After extraction the teeth were immediately fixed with Karnovsky. Teeth were than, divided in 2 subgroups, in accordance with specimen\'s treatment. Samples of region of lesion and their lingual counterpart were, then, post fixed according to appropriated protocol for SEM. The following groups were studied: Group I - specimens sectioned with diamond disc and subdivided in: Group IA- specimens cleaned in ultrasonic bath for 15 minutes; Group IB - cleaned in ultrasonic bath 15 minutes, followed by etching with 5%, H3PO4, for 15 seconds. Group II - samples were fractured along the lesions axis and subdivided in: Group IIA - ultrasonic bath for 30 minutes; Group IIB -etching with 5%, H3PO4, for 15 seconds. Group III - samples also fractured and subdivided in: Group IIIA (control) - without any kind of treatment; Group IIIB - immersion of the specimens in NaOCl to 2%, for 5 minutes. The specimens were dehydrated, critical point dried and coated with gold for in SEM analysis. Results - 1- On general, all of methods interfere, in larger or lesser proportion, with the nature of the specimens. On the surface of the lesions, the method that better allowed the visualization and recognition of dentine structures was the ultrasound followed by acid conditioning (Group IB). However, this was the procedure that introduced the greatest changes on dentine structures. In dentine under of the lesion, the best method of specimens preparation was the control group (Group IIIA). 2- Both buccal NCCL and lesion-free lingual surfaces presented similar ITS. 3- No structural differences were found in dentin from hypersensitive and non-sensitive lesions. Conclusions - The methods used for specimens tend to modify the characteristics and relationship of dentin structures. The hypothesis that ITS are specific from NCCL could not be confirmed under the light of method used. Apparently, the ITS can be found in both hypersensitive and non-hypersensitive dentin.

Pacientes com altos padrões de higiene bucal frequentemente procuram tratamento retração gengival (RG) bucal devido ao desgaste cervical, sensibilidade radicular e comprometimento estético. A lesão cervical (LCNC) é comumente gerada por técnicas inadequadas de escovação, compartilhando a mesma etiologia da RG. Muitas abordagens cirúrgicas diferentes foram descritas para o tratamento das RG. A associação de um enxerto ao retalho coronário avançado demonstrou o melhor resultado a longo prazo para o recobrimento radicular (RR). Mas substitutos para o enxerto autógeno devem ser estudados. Portanto, o objetivo deste ensaio clínico foi investigar a eficácia do enxerto de matriz dérmica acelular (EMDA) no RR de RG associada a uma lesão cervical restaurada anteriormente (GT) ou não (GC). Dezessete indivíduos com RG bilateral foram incluídos no estudo. Todos os pacientes foram tratados com a técnica do retalho estendido associada à EMDA. Todos os parâmetros clínicos foram avaliados no início e após 6 meses de pós-operatório. As médias de RR (GC: 70% ± 19 e TG: 72% ± 16; valor de p = 0,6604) não diferiram significativamente entre os grupos. Aos 6 meses, houve uma redução média na RG de 2,2mm (± 0,5), 2,4mm (± 0,5), no NCI de 1,9mm (± 1,3) e 2,1mm (± 1,2), para o GC e GT, respectivamente. . Além disso, a altura do MQ e a EMQ apresentaram um aumento para o período de acompanhamento. O ADMG é um substituto de sucesso para ETC para RR de LCNC. Mais estudos devem ser realizados para elucidar precisamente como a EMDA contribui nesses casos / Patients with high standards of oral hygiene frequently search for buccal gingival recession (GR) treatment due to cervical wear, root sensitivity and compromising aesthetics. The cervical lesion (NCCL) is commonly produced by improper toothbrushing techniques, sharing the same etiology of GR. Many different surgical approaches have been described. The association of a graft to the coronally advanced flap had demonstrated the best long-term outcome for root coverage. But, substitutes for the autogenous graft must be studied. Therefore, the aim of this clinical trial was to investigate the effectiveness of the acellular dermal matrix graft (ADMG) in root coverage associated with a previous restored cervical lesion or not. Seventeen individuals with bilateral GR were included in the study. At one side, the GR must present a previously restored cervical lesion, as the test group (TG). The contralateral arch, must present GR with an intact root surface (CG). All patients were treated with the extended flap technique associated with the ADMG. All clinical parameters were assessed at baseline and 6-months postoperative. Root coverage means (CG: 70% ±19 and TG: 72% ±16; p value = 0.6604) were not significant different between groups. At 6-months, there was a mean reduction in GR of 2.2mm (±0.5), 2.4mm (±0.5), in CAL of 1.9mm (±1.3) and 2.1mm (±1.2), for CG and TG, respectively. In addition, the KT height and KTT presented an increase for the follow up period. The ADMG is a successful substitute to CTG for root coverage of NCCL defects. More studies should be performed in order to elucidate precisely how the ADMG works in these cases

Twenty-five patients with skeletal class III dentofacial deformities (10 men, 15 women; mean age, 29.28 ? 8.22 years; range 18-48 years) were included in this prospective clinical study. Lateral cephalographs were taken in natural head position (NHP) 2 weeks before and 6 months after orthognathic surgery. The reproducibility of the radiographer?s technique of taking radiographs in NHP was investigated using a photographic method and found to be acceptable. All measurements for cervical lordosis (CV1/CV2; CV3/CV7; CV1/CV7), head posture (NSL/OPT; NSL/VER) and other cephalometric values (NSL/Go-Gn; NSL/Ocl; Overjet) were repeated three times by the same investigator at 2- week intervals and the average values of the three measurements were calculated to use in statistical analysis. Intraclass correlation coefficients (ICC) ranged between 0.996 to 1.000, demonstrating a high reliability of the measures. Statistically significant differences were found for CV3/CV7 (P=0.006) and CV1/CV7 (P=0.005) and no significant differences were identified in head posture for both cranio-cervical and cranio-vertical angles. The null hypothesis was rejected. Orthognathic surgery resulted in significant cervical lordosis extension, and a tendency for head extension could also be observed. / O objetivo deste estudo foi avaliar, por hip?tese nula, a lordose cervical e as altera??es da postura da cabe?a usando telerradiografias de perfil ap?s cirurgia ortogn?tica bimaxilar para corre??o de prognatismo mandibular. Vinte e cinco pacientes com deformidades dentofaciais esquel?ticas classe III (10 homens, 15 mulheres, idade m?dia entre 29,28 ? 8,22 anos, intervalo de 18-48 anos) foram inclu?dos neste estudo cl?nico prospectivo. As radiografias laterais dos pacientes foram obtidas na posi??o natural de cabe?a (PNC) 2 semanas antes e 6 meses ap?s a cirurgia ortogn?tica. A reprodutibilidade da t?cnica do radiologista para realizar as tomadas radiogr?ficas na PNC foi investigada usando um m?todo fotogr?fico e considerada aceit?vel. As medidas para lordose cervical (CV1/CV2; CV3/CV7; CV1/CV7), postura da cabe?a (NSL/OPT; NSL/VER) e outros valores cefalom?tricos (NSL/Go-Gn; NSL/Ocl; Overjet) foram repetidas tr?s vezes pelo mesmo investigador em intervalos de 2 semanas e os valores m?dios das tr?s medidas foram calculados para serem usados na an?lise estat?stica. Os coeficientes de correla??o intraclasse (ICC) variaram entre 0,996 e 1,000, demonstrando uma alta confiabilidade das medidas. Foram encontradas diferen?as estatisticamente significativas para CV3/CV7 (P=0,006) e CV1/CV7 (P=0,005). N?o foram identificadas diferen?as significativas na postura da cabe?a para os ?ngulos cr?nio-cervical e cr?niovertical. A hip?tese nula foi rejeitada. A cirurgia ortogn?tica resultou em aumento significativo da lordose cervical (extens?o) e tamb?m em uma tend?ncia ? extens?o da postura da cabe?a.

A saúde oral proporciona equilíbrio que interfere diretamente na saúde geral e psicológica. É importante que o dentista faça avaliação detalhada dos esportistas, detectando alterações e patologias que possam comprometer o desempenho durante treinos e/ou competições. As LCNCs apresentam etiologia multifatorial e são caracterizadas pela perda de estrutura dental na região de junção cemento-esmalte (região cervical), não relacionadas à presença de cárie, sendo comumente encontradas na rotina clínica odontológica. A perda de estrutura dental provocado pela presença das LCNCs pode levar a exposição dos túbulos dentinarios, possibilitando o aparecimento da HD. Essa dissertação teve como objetivos principais avaliar a prevalência de LCNCs e HD em atletas profissionais (GA) e a presença de fatores de risco associados ao estilo de vida de atletas. Após autorização do CEP, avaliou-se 264 atletas profissionais com no mínimo 17 anos e que realizavam treinamento mínimo de 10 hrs/semana, e 195 indivíduos no grupo controle. Aplicou-se questionário com tópicos como: dieta, DTM e parafunção. No exame clínico avaliou-se fatores oclusais, periodontais, presença de LCNC e HD. chave). Alguns dos resultados encontrados foram: a média de idade dos atletas foi de 20,33 anos, e do controle 23,75. O GC apresentou maioria do gênero feminino (61,54%, p<0,001), enquanto que o GA foi predominância masculina (90,46%). Os atletas consomem mais isotônicos (26,52%, p<0,001), refrigerantes (68,56%, p=0,010) e suplementos (38,64%, p<0,001) do que o GC. A prevalência de biocorrosão foi de 28,03% no GA e 15,38% no GC. Os incisivos inferiores (25,75%) foram os dentes mais afetados com HD, e os pré-molares com LCNC no GA. Os atletas apresentaram maior número de ausências de pelo menos um dente (21,21%, p<0,001) quando comparadas ao grupo controle. O GA apresentou mais alteração em sua mordida (47,43%, p<0,001) do que o GC. Dentro das limitações do nosso estudo, conclui-se que: a prevalência de LCNC e de HD em atletas foram de 17,42% e 35,25% respectivamente; a prevalência de LCNC e HD no grupo controle foi de 18,97% e 48,20% respectivamente; os atletas apresentaram diversos fatores de risco para o desenvolvimento das alterações, sendo eles: ingestão de isotônicos, refrigerantes e suplementos; presença elevada de placa bacteriana; maior ausência de elementos dentários; alteração maxilo-mandibular, ausência de guia canina e escovação imediata após ingestão de alimentação acida. / The oral health provides balance that directly affects the general and psychological health. It is important that the dentist make detailed evaluation of athletes, detecting changes and conditions that may compromise performance during training and / or competition. The LCNCs have multifactorial etiology and is characterized by loss of tooth structure in the cementum-enamel junction region (neck), unrelated to the presence of caries, it is commonly found in dental practice routine. The loss of tooth structure caused by the presence of LCNCs can lead to exposure of dentinal tubules, allowing the appearance of the HD. Thus, this thesis has as main objectives to assess the prevalence of LCNCs and HD professional athletes (GA), to assess the prevalence of LCNCs and HD in the control group (CG). After approval of the CEP, we evaluated 264 professional athletes with at least 17 years and performed minimal training 10 hrs / week and 195 individuals in the control group. applied questionnaire with topics such as diet, DTM and parafunction. On examination it evaluated occlusal, periodontal factors, presence of LCNC and HD. Some of the results were: the average age of the athletes was 20.33 years, and control 23,75. GC showed most females (61.54%, p<0,001), while the GA was predominantly male (90.46%). Athletes consume more isotonic (26.52%, p<0,001), soft drinks (68.56%, p=0,010) and supplements (38.64%, p<0,001) than the GC. The prevalence of biocorrosion was 28.03% in GA and 15.38% in the control group. The lower incisors (25.75%) were the teeth most affected by HD, and the pre molars with LCNC in GA. The athletes had higher number of absences of at least one tooth (21.21%, p<0,001) compared to the control group. The GA had more change in your bite (47.43%, p<0,001) than the GC. Within the limitations of our study, it is concluded that: the prevalence of LCNC and HD athletes were 17.42% and 35.25% respectively. The prevalence of LCNC and HD in the control group was 18.97% and 48.20% respectively. Athletes had several risk factors for the development of changes, namely: isotonic intake, soft drinks and supplements; high presence of plaque; greater absence of teeth; maxillo-mandibular change, absence of canine guidance and immediate brushing after food intake acidic.
