The purpose of this study was to evaluate the periodontal conditions of removable partial denture (RPD) wearers, comparing direct and indirect abutment teeth, and the teeth not involved in the denture design before denture placement and 1 year later. Fifty patients (32 women and 18 men), average age 45, were assessed by the same examiner at the moment of denture insertion and 3, 6, 9 and 12 months later. The following items were verified in each assessment: probing depth (PD), plaque index (PI) and gingival index (GI). PD and PI data were evaluated by anova test for linear trend followed by Tukey-Kramer post-test, while GI data were analysed by Friedman's test. Results showed that the teeth not involved in the denture design were the least affected for all variables studied. It was also verified that PD and GI mean values increased from the initial assessment to 1 year of RPD wearing in every group, but that only PI showed a significant increase. This study indicated that direct and indirect retainer elements tend to undergo more damaging periodontal effects associated with RPD wearing when compared with non-abutment elements. Plaque index values were significantly higher after 1 year of denture use.

Introduction: Orthodontic treatments are performed to improve esthetics and masticatory functions. In general, clinical criteria are used to recommend such treatments without considering the opinion of the patient. This study aimed to evaluate the relationship between technically defined orthodontic need (normative criteria) and the need for treatment perceived by adolescent patients. Methods: A total of 215 students aged between 15 and 19 years were selected and asked to respond to a questionnaire concerning their perception of need for orthodontic treatment and their satisfaction with their own esthetics and mastication. One trained and calibrated examiner obtained normative data using the Dental Aesthetic Index (DAI) on the need for orthodontic treatment of these students. Results: Associations were found between the DAI score and the patient's perception of need for orthodontic treatment (P \0.001), satisfaction with esthetics (P 5 0.003), and satisfaction with mastication (P 5 0.047). When occlusal characteristics were analyzed separately, associations between several normative and perceived needs, as well as for satisfaction with esthetics, were found. Satisfaction with mastication analysis was only found to be associated with open bite malocclusion (P 5 0.003). Conclusions: The DAI revealed a consistent opinion in adolescents to link their perceived malocclusion-related conditions to esthetics.

RESUMOOs problemas de saúde bucal podem impactar na qualidade de vi da relacionada à saúde bucal. Assim, deve-se mensurar além da presença e severidade das doenças bucais, o quanto essas i nterferem no dia-a-dia das pessoas. Pa ra ta nto, utilizam-se i ndicadores de qualidade de vi da rel acionada à s a úde bucal como Ora l Impa cts on Da i ly Performances. Na a dolescência, a umenta o ri s co de cá ri e e doença periodontal e de seus pos síveis impactos (dor de dente, dificuldades na mastigação e na hi gienização dentária), s endo i n dicado o us o consorciado des ses indicadores aos clínicos para o melhor planejamento das a ções. As s im, rea lizou-se es tudo s ecci onal com 215 a dolescentes escolares (15-19 a nos) de um Instituto Federal de Educa ção, Ci ência e Tecnologia para estimar s ua condição de s a úde bucal e verificar a existência de impacto na qualidade de vi da rel acionada à s aúde bucal. Pa ra ta nto, fora m realizados exa mes cl íni cos e a plicados questionário pa ra ca lcular, res pectivamente, indicadores de cárie (índice cariado, perdido e obtura do-CPO-D), de peri odontopatias (Índice Periodontal Comuni tário-CPI), oclusopaticas (Índice de Estética Dental-DAI) e o Ora l Impa cts on Da i ly Performances. Como resultado, obteve-se um CPO-D de 3,31 (±4,15), o cá lculo dentário como peri odontopatia ma is s evera e 31,5% da a mostra com necessidade de tra tamento ortodôntico. Quanto à qualidade de vi da relacionada à s aúde bucal, 51,16% rel a tou i mpacto cuja pri ncipal ca usa foi a posição dos dentes e relativo, sobretudo, à s a ti vi dades de comer, hi gienizar a boca e s orri r. Os a dolescentes a presentaram em s ua maioria dificuldades para rea lizar ao menos uma atividade diária relacionada à boca e a pres ença de cálculo dentário foi o agravo bucal mais prevalente. Es te dado associado às a tivi dades de execução mais dificultada (comer e realizar a higiene bucal) indica que há a necessidade de i nstituir, de fato, ações de promoção e prevenção à saúde. Porta nto, a ções simples e de baixo custo como orientação de hi giene buca l podem reduzir s ensivelmente o i mpacto oca s i ona do no grupo pes qui s a do.
