RESUMOOs distúrbios de desenvolvimento no esmalte apresentam-se como anomalias de estrutura, podendo afetar ambas as dentições. Dentre eles estão a amelogênese imperfeita, a hipoplasia de esmalte e a fluorose dental. A amelogênese imperfeita é uma alteração de caráter hereditário e a hipoplasia de esmalte, um defeito quantitativo do esmalte que ocorre em consequência de problemas sistêmicos, locais e hereditários, ou até da combinação dos mesmos. A fluorose dental é uma hipoplasia gerada pela ingestão crônica de flúor durante o período da odontogênese. Todas essas alterações apresentam características clínicas semelhantes, sendo necessário muito cuidado na sua avaliação. É de extrema importância o conhecimento dessas anomalias para que o diagnóstico diferencial seja instituído e, consequentemente, o plano de tratamento seja estabelecido de forma apropriada para cada situação. Sendo assim, o objetivo do presente trabalho foi realizar uma revisão da literatura a respeito dessas três anomalias do esmalte dental. Por meio desta revisão, concluiu-se que, para estabelecer o diagnóstico diferencial entre essas alterações, assim como um correto plano de tratamento, é necessário o conhecimento das anomalias pelo profissional associado à execução de exame clínico, composto de anamnese e exame físico e, em alguns casos, de exame radiográfico. PALAVRAS-CHAVE:Amelogênese imperfeita; Hipoplasia de esmalte dentário; Fluorose dentária; Esmalte dentário. ABSTRACTThe developmental disorders of enamel are abnormalities of structure which can affect both dentitions. These abnormalities include amelogenesis imperfecta, enamel hypoplasia and dental fluorosis. The amelogenesis imperfecta is a hereditary change and enamel hypoplasia is a quantitative defect of enamel that occurs as a result of systemic problems, local and also inherited factors, or even the combination of them. Dental fluorosis is a hypoplasia caused by the chronic ingestion of fluoride during odontogenesis. All these anomalies have similar clinical characteristics, and it is necessary to be careful in their assessment. It is extremely important to know these abnormalities to establish a differential diagnosis and, consequently, a treatment plan, which can be set for each situation. Therefore, the purpose of this study was to review the literature regarding these three anomalies: amelogenesis imperfecta, enamel hypoplasia and dental fluorosis. It was concluded that to establish the differential diagnosis of these abnormalities as well as a proper treatment plan, it is indispensable the professional knowledge associated with the clinical examination. The examination has to consist of medical history and physical examination, and in some cases, x-ray examination.

RESUMOO estudo avaliou a autopercepção de saúde bucal de idosos institucionalizados e não institucionalizados do município de Araraquara/SP. Foram selecionados 40 moradores da Instituição de Longa Permanência (ILP) e 40 frequentadores de um Grupo da terceira idade (SESI), com faixa etária entre 60 e 95 anos, de ambos os sexos. Os participantes foram questionados sobre suas condições sociodemográficas, submetidos à avaliação cognitiva por meio do Mini Exame do Estado Mental (MEEM) e posteriormente, avaliados quanto à autopercepção de saúde bucal com o Geriatric Oral Health Assessment Index (GOHAI). Os dados foram analisados descritivamente. Os resultados mostraram que prevaleceu o gênero feminino, com idade entre 70 e 79 anos, a maioria analfabeta ou com ensino fundamental incompleto, 50% moravam com companheiro e 25% sozinhos ou com a família. Encontrou-se condição de normalidade tanto para o grupo não institucionalizado como institucionalizado (65,0% e 87,5%, respectivamente) na avaliação cognitiva. Para o GOHAI, 85% no SESI e 92,5% na ILP não sentiam desconforto ao engolir alimentos. Quanto à satisfação com dentes e próteses, 72,5% do grupo da ILP consideram-se parcialmente felizes ou descontente. Na avaliação clínica, houve queixa frequente de sensação de boca seca; 85% do SESI utilizavam prótese, das quais 62,5% eram satisfatórias; na ILP, 72,5% usavam próteses, das quais 22,5% apresentaram desgaste excessivo. Dessa forma, conclui-se que a autopercepção de saúde bucal dos idosos institucionalizados e não institucionalizados é baixa, o que sugere o planejamento de ações de educação e prevenção em saúde bucal das principais doenças que acometem esses indivíduos.

SELF-PERCEPTION OF ORAL HEALTH IN INSTITUTIONALIZED AND NON-INSTITUTIONALIZED ELDERLY PEOPLE IN THE CITY OF ARARAQUARA-SP ABSTRACTThe study evaluated the self-perception of oral health in institutionalized and non-institutionalized elderly in the city of Araraquara -SP. The selected participants were 40 residents at a long stay institution (LSI) and 40 regulars from a group of seniors (SESI), aged between 60 and 95 years, of both genders. Participants were asked about their socio-demographic conditions, they performed a cognitive assessment test based on the Mini Mental State Examination (MMSE) and subsequently were evaluated for the self-perception of oral health with GOHAI (Geriatric Oral Health Assessment Index). The data were analyzed descriptively. The results showed that prevailed females, aged between 70 and 79 years, mostly illiterate or with incomplete primary education,
Composite resins are materials that can present color changing when exposed to pigments. Objective: The aim of this study was to evaluate, in vitro, the color changing of composites after immersion in different substances for different periods. Material and methods: Two microhybrid composite resins: Charisma (Heraeus – Kulzer) and Opallis (FGM) were used. Red wine and acai pulp were also used as immersion medium. For this study, 32 specimens with 10 mm of diameter and 2 mm of thickness were used, divided into 4 groups: Group 1 – Opallis composite immersed in red wine solution; Group 2 – Opallis composite immersed in acai berry pulp solution; Group 3 – Charisma composite immersed in red wine solution; Group 4 – Charisma composite immersed in acai berry pulp solution. The specimens were evaluated in the following time periods: T0 – baseline, T1 – 24 hours, T2 – 48 hours, T3 – 72 hours and T4 – 96 hours. For the assessment of staining, a spectrophotometer for colorimetry was used (Color Guide 45 / 0, PCB 6807 BYK-Gardner Gerestsried GmBH, Germany), and the values obtained were transferred to a computer and recorded according to CIELAB system. Results: The data were evaluated using Kruskal-Wallis non-parametric tests with the following ���ΔE mean values for � �the immersion periods of 24, 48, 72 and 96 hours, respectively: G1 – 7.35, 7.84, 9.04,10.48; G2 – 2.92, 4.15, 4.30, 4.64; G3 – 3.14, 7.35, 8.13, 8.43, G4 – 4.49, 5.99, 6.92, 6.76. Conclusion: Red wine showed a higher tendency toward altering the composite color than acai berry pulp. In addition, no significant difference was found concerning to the behavior of the two composite resins. Concerning to the immersion time periods, significant differences were only observed among the groups in the 24 hour time period.
Objective: The aim of this study was to evaluate the effi cacy of a bleaching material (hydrogen peroxide [HP]) in diff erent concentrations (20% and 35%) as well as the susceptibility to staining after the bleaching procedure. Materials and Methods:The root portions of 20 healthy bovine incisors were removed, and the crowns were sectioned, obtaining mesial and distal halves, totaling 40 specimens. The specimens were identifi ed as 1-20 (G1) for the mesial half and 21-40 (G2) for the distal half. The specimens of G1 were subjected to staining with coff ee and subsequently subjected to bleaching with HP 35% (specimens 1-10) and HP 20% (specimens 11-20). The specimens of G2 were stained with acai berry and later bleached with HP 35% (specimens 21-30) and HP 20% (specimens 31-40). After bleaching, the specimens were again subjected to staining with the same substances. The colorimetry system (CIELab) was carried out with a spectrophotometer at fi ve diff erent moments: Before the fi rst staining, after the fi rst staining and previously to the fi rst session of bleaching, previously to the second bleaching session, previous to the second staining, and fi nally after the second staining. Results: No diff erence was found between HP 35% and 20%, and both materials signifi cantly promoted bleaching. Conclusions: The acai solution resulted in more staining compared to the coff ee solution, before and after bleaching. No increase was observed in susceptibility to staining after bleaching of the bovine teeth.
