Objective- To determine the impact of the COVID-19 pandemic on dental anxiety (DA) and oral health related quality of life (OHRQoL) proxy measures using electronic dental records from Temple University Kornberg School of Dentistry (TUKSoD). Methods- A cross-sectional study comparing data before the COVID-19 Pandemic (G1) (N=4,516) and before (G2) (N=3,995) and after the vaccine was available (G3) (N=3,891) was analyzed for patients 18 and older. The independent variables are age, sex, race, diabetic status, hypertension status, and DA. The dependent variable – OHRQoL – has four components (trouble while chewing, speaking, embarrassment due to dental problems, and pain/ sensitivity) which were converted to a composite score for analysis. OHRQoL, were coded as good, fair, and poor. Mann-Whitney U tests were used to assess outcome differences across the three groups. Statistical significance was set at p<0.05. Results- The proportion of individuals with poor DA in G1, G2, and G3 were about 5%, 3%, and 4% respectively. The proportion of individuals with poor OHRQoL were 8%, 5%, and 4% in G1, G2, and G3, respectively. About 26%, 21%, 19% reported poor social interactions in G1, G2, and G3, respectively. About 1% of individuals in G1, G2, and G3 reported poor speaking. About 8%, 3%, and 5% reported poor chewing in G1, G2, and G3, respectively. About 4% of individuals in G1 and 3% in both G2 and G3 reported poor comfort. Significant differences in DA were observed between G1 vs G2 (p=<0.01) and G1 vs G3 (p=<0.01). Also, significant differences in OHRQoL between G1 vs G2 (p=<0.01), G2 vs G3 (p=0.01), and G1 vs G3 (p-value=<0.01). Associations between DA and OHRQoL were seen across G1, G2, and G3. Hypertension and diabetic status also seemed to be associated with OHRQoL at multiple points in this study. Conclusion- Overall, OHRQoL and dental anxiety improved post COVID-19 vaccine availability compared to the pre-COVID-19 vaccine availability and the pre-COVID-19 pandemic. This could be attributed to increased health consciousness triggered by the COVID-19 events. / Oral Biology

In der vorliegenden Untersuchung sollte ein möglicher Zusammenhang zwischen mundgesundheitsbezogener Lebensqualität (MLQ) und Depression untersucht und bei prothetischen Patienten und Personen der Allgemeinbevölkerung vergleichend betrachtet werden. Es handelt sich um eine Querschnittsstudie, in welche 311 zahnärztlich-prothetische Patienten und 811 erwachsene Probanden der Bundesrepublik Deutschland einbezogen wurden. Zur Erfassung von MLQ und Depression wurden als standardisierte Instrumente zum einen die deutsche Version des Oral Health Impact Profile (OHIP) und zum anderen das Vereinfachte-Beck-Depressions-Inventar (BDI-V) eingesetzt. Die statistischen Zusammenhänge der Konstrukte wurden mit Hilfe von Korrelationsanalysen sowie Strukturgleichungsmodellen ermittelt. Die konfundierenden Variablen Alter und Geschlecht wurden dabei kontrolliert. In beiden Populationen wurde ein signifikanter Zusammenhang zwischen Depression und MLQ festgestellt. Diese gegenseitige Beeinflussung zwischen MLQ sowie deren Dimensionen und der Depression war jedoch zwischen den beiden Probandengruppen signifikant unterschiedlich stark ausgeprägt. Bei den prothetischen Patienten war der Zusammenhang nur halb so stark ausgeprägt wie bei den Personen der Allgemeinbevölkerung. Die OHIP-Dimension „Psychosozialer Einfluss“ der MLQ korrelierte in beiden Probandengruppen signifikant stärker mit Depression als die anderen Dimensionen. Folglich könnte sie auf eine mögliche Depression hinweisen und als zahnärztliches Diagnostikum eingesetzt werden. Zudem legt diese Studie nahe, dass eine eingeschränkte MLQ möglicherweise erst zeitversetzt zu depressiven Symptomen führen kann.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / The aim of this study was to assess the occurrence and magnitude of racial inequalities in clinical and subjective oral health outcomes in Brazilian adolescents. A survey was conducted in 2012 with a multistage sample of 12 years-old schoolers in the city of Santa Maria, RS, Brazil. Data were collected through oral clinical examinations and structured interviews. The clinical variables evaluated were: dental caries, dental plaque, calculus and gingival bleeding. Participants answered the Brazilian short version of Child Perception Questionnaire (CPQ11-14) for assessing their Oral Health-related Quality of life (OHRQoL). The socioeconomic status and race were colected throug questionnaires answered by parentes. Variables related to the school neighborhood of the adolescentes were obtained by oficial publications of the city. Data were analysed using STATA 12.0 software. Multilevel Poisson Regresson models were performed to assess the associations between race, clinical variables, oral health-related quality of life and use of dental care. A total of 1,134 adolescents were examined. Non-white individuals presented the worst clinical conditions compared to White ones. Non-white adolescentes had the higher number of missed and less filled surfaces (RR 1.92 CI 1.31-2.82 and RR 0.52 CI 0.37-0.71, respectively); they also presented at a higher rate of dental plaque (RR 1.14 CI 1.09-1.18) and gingival bleeding (RR 1.07 CI 1.02-1.12) when comparing to their white counterparts. There are no racialdiferences in the use of dental services. However, the use of dental services due to pain was higher for non-white adolescents (RR 1.36 CI 1.05-1.77). Non-white adolescents had poorer OHRQoL. The most affected domains were Emotional well-being (RR 1.10 CI 1.00-1.20) and Social well-being (RR 1.16 CI 1.03-1.10). There are racial inequalities in clinical and subjective oral health outcomes as well as the reason for use of dental care in the Brazilian adolescents. The results demonstrate the need for public health policies and programm targing minority ethnic / racial groups to reduce these inequities. / O objetivo desse estudo foi verificar a ocorrência e a magnitude de diferenças raciais em desfechos clínicos e subjetivos de saúde bucal em adolescentes brasileiros. Um levantamento epidemiológico foi realizado, em 2012, com uma amostra de escolares de 12 anos na cidade de Santa Maria-RS, Brasil. Dados foram coletados através de exames clínicos e entrevistas estruturadas. Os critérios clínicos avaliados foram cárie dentária, presença de placa e cálculo dental e sangramento gengival. Os participantes responderam a versão brasileira e reduzida do Child Perceptions Questionnaire (CPQ11-14). As condições socioeconômicas e o principal preditor deste estudo, raça, foram coletados através de questionários respondidos pelos pais. Variáveis relacionadas ao bairro da escola em que as crianças estudavam foram obtidas de publicações oficiais do município. Os dados foram analisados através do programa estatístico STATA 12.0, utilizando o modelo multinível de Regressão de Poisson para determinar as associações entre raça, variáveis clínicas, qualidade de vida relacionada à saúde bucal e uso de serviços odontológicos. Um total de 1134 adolescentes foi examinado. Indivíduos não-brancos apresentaram piores condições clínicas quando comparados aos brancos. Em relação à cárie, adolescentes não-brancos tiveram maior número de dentes perdidos e menor número de dentes restaurados (RR 1,92 IC 1,31-2,82 e RR 0,52 IC 0,37-0,71, respectivamente). Relacionado às condições periodontais, o mesmo grupo apresentou maior taxa de placa dental (RR 1,14 IC 1,09-1,18) e sangramento gengival (RR 1,07 IC 1,02-1,12). Não houve diferenças relacionadas ao uso de serviços odontológicos. No entanto, a procura por motivo de dor foi maior para adolescentes não-brancos (RR 1,36 IC 1,05-1,77). Adolescentes não-brancos apresentaram uma pior qualidade de vida relacionada à saúde bucal. Os domínios mais afetados do CPQ 11-14 foram Bem estar Emocional (RR 1,10 IC 1,00-1,20) e Bem estar Social (RR 1,16 IC 1,03-1,10). Existem desigualdades raciais em desfechos clínicos, subjetivos e no motivo do uso de serviços em adolescentes brasileiros. Os resultados apontam a necessidade de políticas públicas de saúde que considerem a existência dessas diferenças e reforcem a atenção a grupos étnicos minoritários no intuito de reduzir essas inequidades.

Syfte: Att studera hur unga vuxna upplever och påverkas av tänders utseende. Metod: En kvalitativ studie med semistrukturerade frågor utfördes. Sex studenter från Jönköping University (JU) i åldrarna 19–29 år intervjuades. Insamlat datamaterial analyserades utifrån metoden manifest innehållsanalys. Resultat: Informanterna uttryckte en kluven upplevelse av det ideala tandutseendet då de uttryckte att perfekta tänder är målet, men även uttryckte förståelse för att tänder kan se olika ut. Ytterligare beskrev informanterna att tänders utseende kan ha emotionell påverkan genom påverkad självkänsla och självförtroende. Tandutseendet kan även bidra till fördomar och påverkar förhållningssättet gentemotindividen. Dessutom kan tandutseendet skapa föreställningar om en individs livssituation med avseende på ekonomiska resurser, tandvårdserfarenhet, orala hygienvanor och livsstilsvanor. Slutsats: Tänders utseende framstår tydligt som en del av den psykosociala funktionen av oral hälsa och har därmed påverkan på en individs orala hälsorelaterade livskvalité (OHRQoL). Tandvårdspersonal bör därför alltid beakta samtliga aspekter av den orala hälsan för att kunna tillhandahålla bästa möjliga patientomhändertagande samt bidra till att optimera patientens OHRQoL. / Aim: To study how dental appearance is perceived by young adults and how it impacts them. Method:A qualitative study consisting of semi-structured interviews was conducted. Six students from Jönköping University (JU) aged 19–29 participated in the interviews. The collected data was analyzed by using manifest content analysis. Results: The informants presented a divided perception of the ideal dental appearance. They expressed both a desire for perfect teeth and an understanding of variations in dental appearances. The informants further described that the appearance of teeth can have an emotional impact through affected self-esteem and self-confidence. Dental appearance also contributes to prejudice and affects the attitude towards the individual. Furthermore, dental appearance can create ideas of an individual's life situation regarding financial resources, dental care experience, oral hygiene- and lifestyle habits. Conclusion: Dental appearance clearly appears to be a part of the psychosocial function of oral health and thus has an impact on an individual’s oral health related quality of life (OHRQoL). Dental professionals should therefore consider all aspects of oral health in order to provide best possible patient care and optimize the patients' OHRQoL.

Abstract Purpose Aim of this exploratory study was to investigate whether a retrospective assessment of oral health-related quality of life (OHRQoL) using the Oral Health Impact Profile (OHIP) is susceptible to bias such as implicit theory of change and cognitive dissonance. Methods In this prospective clinical study, a sample of 126 adult patients (age 17–83 years, 49% women) requiring prosthodontic treatment was consecutively recruited. The OHRQoL was assessed using the 49-item OHIP at baseline and at follow-up. Additionally, patients were asked at followup to retrospectively rate their oral health status at baseline (retrospective pretest or then-test) and the change in oral health status using a global transition question. Furthermore, patients’ ratings of overall oral health and general health were used as validity criteria for the OHRQoL assessments. Response shift was calculated as the difference between the initial and retrospective baseline assessments. Results Baseline and retrospective pretest did not differ substantially in terms of internal consistency and convergent validity. Response shift was more pronounced when patients perceived a large change in OHRQoL during treatment. Retrospective pretests were more highly correlated with the baseline than with the follow-up assessment. Conclusion Findings suggest that retrospective assessments of OHRQoL using the OHIP-49 are susceptible to bias. Cognitive dissonance is more likely to appear as a source of bias than implicit theory of change.:Inhaltsverzeichnis 1. Einführung in die Thematik…………………………………………………2 2.

Syfte Syftet med denna studie var att undersöka hur tandförlust påverkar den orala hälsorelaterade livskvalitén genom ett OHIP-14 fråge-formulär samt ytterligare konstruerade frågor, bland patienter som besöker Kantipur Dental College and Hospital (KDCH) i Katmandu, Nepal. Material och metod Data erhölls från ett frågeformulär baserat på OHIP-14, kompletterande frågor och klinisk undersökning. Studien var av beskrivande karaktär och undersökte konsekutiva patienter (n=249) som besökte KDCH. Data från ifyllda formulär analyserades genom SPSS för att undersöka sambandet mellan tandförlust och påverkan på livskvalitén. Resultat Medelåldern var 47.6 år med en könsfördelning på 48 % (n=119) män och 52 % (n=130) kvinnor. Det genomsnittliga antalet saknade tänder var 5, och den genomsnittliga totala OHIP-poängen var 21.57 (SD 12.55). De mest påverkade dimensionerna för OHIP-14 var "Fysisk smärta" (77 %) och "Psykologiskt obehag" (82.5 %). 96.8 % av den undersökta befolkningen upplevde någon form av påverkan på deras orala hälsorelaterad livskvalitet. Slutsats Resultaten i denna studie visar att en stor majoritet av patienterna som besöker KDCH upplever någon form av påverkan på sin oral-hälsorelaterade livskvalitet relaterad till tandförlust. De saknade tändernas position hade ingen signifikant effekt på den orala hälsorelaterade livskvaliteten medan en större inverkan på livskvalitén kunde observeras vid ökande antal saknade tänder. De OHIP-poäng, utifrån de kriterier som använts i denna studie, visade sig vara högre i jämförelse med andra internationella fynd. / Aim The aim of this study was to investigate how tooth loss affects the oral health related quality of life through an OHIP-14 questionnaire and additional questions among patients visiting the Kantipur Dental College and Hospital (KDCH) in Kathmandu, Nepal. Materials and method Data was obtained from a questionnaire based on the OHIP-14 form, additional questions and a clinical examination. The study was of a descriptive nature and investigated consecutive patients (n=249) visiting the KDCH. Data from completed forms were analysed with SPSS to investigate how tooth loss affects the oral health related quality of life (OHRQoL) Results Mean age was 47.6 years with a gender ratio of 48 % (n=119) male and 52 % (n=130) female. The mean number of missing teeth was 5, and the mean total OHIP-score was 21.57 (SD 12.55). The most frequently impacted dimensions for the OHIP-14 were “Physical pain” (77 %) and “Psychological discomfort” (82.5 %). 96.8 % of the investigated population experiencing some form of impact on their OHRQoL. Conclusion A large majority of the patients visiting the KDCH experienced an impact on their OHRQoL related to missing teeth. The number of missing teeth had an impact on OHRQoL, but the position of missing teeth had not. The OHIP score with the criteria used in this study was found to be higher in comparison to other international findings.

Objetivos: Avaliar a efetividade entre diferentes intervalos de retorno na incidência de cárie em pré-escolares que apresentaram risco baixo de cárie dentária, e também, avaliar o nível de ansiedade e qualidade de vida relacionada à saúde bucal (QVRSB) das crianças de acordo com cada intervalo empregado. Métodos: A amostra foi composta por 224 crianças de escolas públicas, com idade entre 3 a 5 anos, de ambos os sexos, com baixo risco de cárie. As crianças foram alocadas aleatoriamente em dois grupos de estudo, de acordo com dois intervalos de retorno, sendo: Grupo 1 (G1) - exame clínico bucal + escovação dental profissional + orientação de higiene bucal e dieta no intervalo de retorno de 12 meses e Grupo 2 (G2) - exame clínico bucal + escovação dental profissional + orientação de higiene bucal e dieta no retorno de 18 meses. O exame clínico bucal foi realizado por um examinador previamente calibrado e cego aos grupos de estudo e aos desfechos secundários. O exame clínico bucal incluiu o índice de sangramento gengival de Löe, índice de biofilme dentário de Greene e Vermillion simplificado, detecção de lesões de cárie e da sua atividade de acordo com o ICDAS (International Caries Detection and Asessment System). O nível de ansiedade e a QVRSB foram avaliados pela Escala de Imagem Facial e pelo B-ECOHIS, respectivamente, por um dentista externo. O dentista externo também realizou as orientações sobre higiene bucal e dieta, e a avaliação das condições socioeconômicas. Os testes qui-quadrado e o de Mann-Whitney foram utilizados para avaliar a diferença na proporção de crianças e na média de dentes com novas lesões de cárie entre G1 e G2, respectivamente. Análises de Regressão de Poisson com variância robusta foram realizadas para avaliar o desfecho primário de incidência de cárie dentária considerando dois pontos de corte durante os retornos: 1) incidência de lesões de cárie não cavitadas ativas; 2) incidência de lesões cavitadas em dentina. Resultados: Foi observado uma diferença estatisticamente significativa unicamente para a incidência de lesões iniciais de cárie ativas entre os grupos (p=0,012). Na consulta de retorno crianças que pertenciam ao G2 tiveram maior risco de desenvolver lesões iniciais ativas em comparação ao G1 (RR= 2,37; p=0,047) e também aquelas com um maior índice de placa bacteriana (RR=3,14; p<0,001). Crianças que moram em família não nuclear (RR=2,56; p=0,007), com mais de um irmão (RR=2,53; p=0,037), e que utilizavam dentifrício sem flúor ou em baixa concentração no baseline (RR=3,91; p=0,012), tiveram maior risco de desenvolver lesões de cárie iniciais ativas. Crianças com maior número de dentes com lesões iniciais ativas nos retornos tiveram maior risco de desenvolver lesões de cárie cavitadas em dentina (RR=1,62; p=0,001). Conclusões: O intervalo de retorno de 12 meses é mais efetivo na incidência de cárie não cavitada ativa em pré-escolares de baixo risco de cárie, sendo que estas lesões são um fator preditivo para a progressão de lesões de cárie cavitadas em dentina. Porém não há diferenças na escolha do intervalo de retorno para lesões cavitadas em dentina, níveis de ansiedade e QVRSB. / Objectives: To assess the effectiveness between different recall intervals on dental caries incidence in preschool children with low risk of caries, as well as, the level of anxiety and oral health-related quality of life (OHRQoL) of children according to each interval applied. Methods: The sample consisted of 224 children from public schools, aged between 3 to 5 years, of both genders, with low risk of caries. The children were randomly allocated into two study groups according to two recall intervals being: Group 1 (G1) - oral clinical examination + professional dental brushing + orientation for oral health and diet on the recall of 12 months and, Group 2 (G2) - oral clinical examination + professional dental brushing + orientation for oral health and diet on the recall of 18 months. A previously calibrated and blinded examiner for study groups and secondary outcomes performed the oral clinical examinations. The examinations consisted of the Löe gingival bleeding index, Greene and Vermillion simplified dental biofilm index, detection of caries lesions and their activity according to the International Caries Detection and Assessment System (ICDAS). An external dentist assessed the anxiety levels and OHRQoL scores by the Facial Imaging Scale and B-ECOHIS, respectively. The external dentist also performed dental hygiene and diet orientations, and the assessment of socioeconomic conditions. The chi-square and Mann-Whitney tests were used to assess the difference in the proportion of children and mean of teeth with new caries lesions between G1 and G2, respectively. Poisson Regression analyses with robust variance were performed to evaluate dental caries incidence considering two cutoff points during the returns: 1) incidence of active non-cavitated caries lesions; 2) incidence of cavitated lesions in dentin. Results: A statistically significant difference was observed only for the incidence of initial active caries lesions between the groups (p=0.012). In the recall interval children who remain in the G2 group and who had a higher plaque index, had a higher risk of developing active lesions (RR=2.37; p=0.047 and RR=3.14; p<0.001, respectively) compared to the G1 group. Children living in non-nuclear families (RR=2.56; p=0.007), with more than one sibling (RR=2.53; p=0.037), and who used fluoride-free or with low concentration in the baseline (RR=3.91; p=0.012) had a higher risk of developing active initial caries lesions. Children with higher number of initial active lesions in the recalls had a higher risk of developing caries lesions cavitated in dentin (RR=1.62; p=0.001). Conclusions: The 12-months recall interval is more effective on the incidence of active non-cavitated caries in preschoolers with low risk caries, which is a predictive factor for the progression of cavitated carious lesions in dentin. There are no differences in the choice of the recall interval for cavitated lesions in dentin, anxiety levels and OHRQoL.
