Orientador: Mauro Pedrine [Unesp] Santamaria / Resumo: A recessão gengival está frequentemente associada à hipersensibilidade dentinária e insatisfações estéticas. Diversas técnicas cirúrgicas foram desenvolvidas a fim de reestabelecer a posição da margem gengival acometida. Dentre elas, a adição de biomateriais aos procedimentos cirúrgicos de retalho posicionado coronariamente (CAF) é considerada uma alternativa promissora. O objetivo do presente estudo foi comparar os efeitos do uso de dois enxertos, matriz colágena (CM, Mucograft®) e matriz dérmica acelular xenógena (XDM, Mucoderm®), no tratamento de recessões gengivais unitárias associados ao CAF. Para tal, 75 pacientes portadores de recessões gengivais unitárias foram selecionados e divididos em três grupos: CAF (n=25, técnica isolada de CAF para recobrimento radicular), CAF+CM (n=25, CAF associado à CM) e CAF+XDM (n=25, CAF associado à XDM). Os parâmetros clínicos e centrados no paciente foram avaliados no baseline e seis meses após o tratamento. Aos seis meses, os três grupos apresentaram porcentagens significativas de recobrimento radicular (78,9±26,2% para CAF, 78,0±28,5% para CAF+CM e 65,6±26,9% para CAF+XDM), sem diferença significativa entre os grupos (p>0,05). O recobrimento radicular completo foi obtido em 52%, 48% e 28% dos casos tratados com CAF, CAF+CM e CAF+XDM, respectivamente (p=0,2). Os grupos que receberam enxerto apresentaram maior ganho de espessura de tecido queratinizado (ETQ; p<0,001). Não foram observadas diferenças no grau de edema tecidual (p=0,9) e ...

Different periodontal surgical techniques have been developed in order to reestablish the position of the gingival margin. The addition of biomaterials to coronally advanced flap (CAF) surgical procedures is considered a promising alternative. The aim of this study was to compare the effects of using two biomaterials, collagen matrix (CM, Mucograft®) and xenogeneic acellular dermal matrix (XDM, Mucoderm®) associated with CAF technique for the treatment of single gingival recessions. For this, 75 patients presenting single gingival recessions were selected and allocated into three groups: CAF (n=25, CAF for root coverage alone), CAF+CM (n=25, CAF associated with CM) and CAF+XDM (n=25, CAF associated with XDM). Clinical and patient-centered parameters were assessed at baseline and six months post-procedures. At six months, the groups had significant percentages of root coverage (78.9±26.2% for CAF, 78.0±28.5% for CAF+CM e 65.6±26.9% for CAF+XDM), with no intergroup difference. Complete root coverage was obtained in 52%, 48% and 28% of cases treated with CAF, CAF+CM and CAF+XDM, respectively (p=0.2). The groups which received some graft showed greater gain in keratinized tissue thickness (p<0,001).No differences were observed in tissue edema (p=0.9) and postoperative discomfort (p=0.2) at seven days. All groups showed significant dentin hypersensitivity reduction (p<0.001) and impro... (Complete abstract click electronic access below) / Mestre

Kalciumkanalblockerare är ett av de tre kända läkemedel som orsakar gingival hyperplasi. Prevalensen varierar mellan 3-86% och det ses en skillnad mellan de olika klasserna av kalciumkanalblockerare. Amlodipin tillhör den klass som har störst prevalens men biverkningen anges som sällsynt. Syftet med studien var främst att få klarhet i hur vanligt det är med biverkningen gingival hyperplasi hos patienter som behandlas med amlodipin men också att uppmärksamma följderna biverkningen kan orsaka. Metoder som användes i studien var en kombination av undersökning av patienter i form av enkätstudie samt en litteraturstudie. Enkätstudien gjordes med hjälp av tandläkare på klinik i Kristianstad. Enda inklusionskriteriet var att patienterna skulle vara under behandling med amlodipin. Information som ålder, gingival overgrowth index och om blödning vid sondering dokumenterades. Litteraturstudien gjordes genom sökning i Pubmed och Online Wiley Library där studier med olika resultat och liknande etnicitet valdes. Resultatet visade att 100% av de 10 patienter som deltog hade någon grad av överväxt i enkätstudien, antingen fas 1 eller 2. Samtliga började blöda vid sondering. Medelåldern för deltagarna var 67,7 år. Resultatet från litteraturstudien visade en prevalens på 3,3%, 86,4% och 45%. Enligt studien var biverkningen vanlig då fler än 1/100 drabbades. Den egna undersökningen är liten och fler mätningar som t.ex på graden plack hade krävts för att utesluta de riskfaktorer som också kan leda till svullnad av tandköttet. Biverkningen kan ge allvarliga följder därför är det viktigt med forsatta studier kring ämnet.

Magister Chirurgiae Dentium (MChD) / Epilepsy is a fairly common condition and the anti-convulsant drug, phenytoin sodium, has been used in its treatment for over 40 years. Shortly after its introduction, the side-effect of gingival overgrowth was re'{XJrted and has been the subject o t of mw h research. Epidemiological studies showed that; gingival overgrowth developed in approximately half the patients treated with this drug, possibly indicating an individual patient susceptibility to this effect of the drug.

Objective: To collect data regarding Canadian laypersons perceptions of smile esthetics and compare these data to US data in order to evaluate cultural differences. Methods: Using Adobe® Photoshop® 7, a digital image of a posed smile of a sexually ambiguous lower face was prepared so that hard and soft tissue could be manipulated to alter Buccal Corridor (BC), Gingival display (GD), Occlusal Cant (OC), Maxillary Midline to Face Discrepancy (MMFD) and Lateral Central Gingival Discrepancy (LCGD). Adult Canadian laypersons (n=103) completed an interactive computer-based survey of 29 randomized images to compare smile preferences for these variable. The custom survey was developed to display fluid, continuously appearing modifiable smile variables using MATLAB® R2008 for presentation. These data were compared to previously published data for US laypersons. Statistical inference was determined using Wilcoxon Rank Sum tests. Results: Canadian laypersons were more sensitive in detecting deviations from ideal and had a narrower range of acceptability thresholds for BC, GD, OC, MMFD and LCGD. Ideal esthetic values were significantly different only for BC. Conclusions: It appears cultural differences do exist related to smile characteristics. Clinically significant differences in the preference of the smile characteristics were found between Canadian and US laypersons. Canadian laypersons, on average, were more discriminating to deviations from ideal and had a narrower range of acceptability.

La estética se ha convertido en una parte importante de la vida de las personas; un factor muy extendido en este sentido es la sonrisa, ya que juega un papel crucial en la apariencia y la autoestima. El popósito del presente trabajo de investigación fue determinar la influencia del patrón facial con diferentes niveles de exposición gingival en la percepción de la estética de la sonrisa, evaluada por estudiantes, personas comunes y odontólogos. Esta investigación es analítica y transversal; la poblacion está constituida por 147 estudiantes de odontología de la USAT, 104 odontólogos que ejercen actividades clínicas en el Centro Especializado en Formación Odontológica (CEFO-USAT) y 264 pacientes atendidos en CEFO-USAT en el año 2023. Se utilizó fotografías de dos mujeres con diferentes tipos de patrones faciales, las cuales fueron importadas en el programa Adobe Photoshop 6.0 para modificar el nivel de exposición gingival (gradualmente en 1mm, de 0 a 3mm) en ambas modelos. Mediante un sistema de escala de Likert se calificó la estética eligiendo entre los números de 1 al 5, que van desde muy desagradable, hasta muy agradable, respectivamente. Finalmente, la encuesta se realizó de manera presencial; a los estudiantes y a los odontólogos y pacientes. Al completar las 515 encuestas se elaboró la matriz de datos en el Excel y se codificaron las respuestas. Se utilizó Kruskal-Wallis para la comparación entre grupos y Spearman para la comparación respecto al grupo etario. Se consideró un nivel de significancia del 5%. / Aesthetics have become an important part of people's lives; A widespread factor in this regard is the smile, as it plays a crucial role in appearance and self-esteem. The aim of this research work was to determine the influence of facial pattern with different levels of gingival exposure on the perception of smile aesthetics, as evaluated by students, ordinary people and dentists. This research is analytical and cross-sectional; the population is made up of 147 dentistry students from USAT, 104 dentists who practice clinical activities at the Specialized Center for Dental Training (CEFO-USAT) and 264 patients treated at CEFO-USAT in 2023. Photographs of two women with different types of facial patterns were imported, which were imported into Adobe Photoshop 6.0 to modify the level of gingival exposure (gradually by 1mm, from 0 to 3mm) in both models. Using a Likert scale system, the aesthetics were rated by choosing between the numbers of 1 to 5, ranging from very unpleasant to very pleasant, respectively. Finally, the survey was conducted in person; to students and to dentists and patients. Upon completion of the 515 surveys, the data matrix was elaborated in Excel and the responses were coded. Kruskal-Wallis was used for the comparison between groups and Spearman for the comparison with the age group. A significance level of 5% was considered.

Introducción: En la actualidad, no existe un protocolo universalmente aceptado para la evaluación clínica de los implantes dentales, siendo la mayoría de ellos de naturaleza tardía.Objetivo: Establecer el patrón de normalidad de la temperatura periimplantar, para introducir un método objetivo de diagnóstico precoz implantológico.Material y métodos: Se incluyeron en el estudio un total de 129 implantes osteointegrados, protésicamente restaurados, y clínicamente sanos, los cuales fueron sometidos a una exploración térmica, clínica y radiográfica.Resultados: Tras aplicar un análisis de conglomerados a la muestra, obtuvimos dos grupos diferenciados estadísticamente, tanto desde el punto de vista del diferencial de temperatura, como desde el de la temperatura periimplantaria.Conclusión: El patrón de normalidad de la temperatura periimplantar va a depender de la localización anatómica del implante en la arcada, pudiendo distinguirse entre una región fría (segundo y tercer sextante) y una región cálida (mandíbula y primer sextante). / Introduction: Nowadays, it does not exist a protocol universally accepted for the clinical evaluation of dental implants, being most of them of late nature. Objetive: to establish a pattern of normality of the periimplant temperature, to introduce an objective method of implantology precocious diagnostic.Material and methods: They were included in the study 129 osteointegrated, restored and clinically healthy. These implants were explored thermally, clinically and radiographically.Results: After applying an analysis of conglomerates to the sample, we obtained two groups differed statistically, so much from the point of view of the differential of temperature, as from the periimplant temperature. Conclusions: The pattern of normality of the periimplant temperature will depend on the anatomical localization of the implant in the arcade, being able to be distinguished among a cold region (formed by the second and third sextant) and a warm region (composed by mandible region and the first sextant).
