Objective: This article aimed to evaluate in vitro the efficiency of Pro
Seal fluoride sealant application in the prevention of white spot lesions around
orthodontic brackets. Material and Methods: Brackets were bonded to the buccal surface of bovine incisors, and five groups
were formed (n = 15) according to the exposure of teeth to oral hygiene substances
and the application of enamel sealant: G1 (control), only brushing was performed
with 1.450 ppm fluoride; G2 (control) brushing associated with the use of
mouthwash with 225 ppm fluoride; G3, only Pro Seal sealant application was
performed with 1.000 ppm fluoride; G4 Pro Seal associated with brushing; G5 Pro
Seal associated with brushing and mouthwash. Experimental groups alternated
between pH cycling and the procedures described. All specimens were kept at a
temperature of 37 °C throughout the entire experiment. Both brushing and immersion
in solutions were performed within a time interval of one minute, followed by
washing in deionized water three times a day for 28 days. Afterwards, an
evaluation by Optical Coherence Tomography (OCT) of the spectral type was
performed. In each group, a scanning exam of the white spot lesion area (around
the sites where brackets were bonded) and depth measurement of carious lesions
were performed. Analysis of variance (ANOVA) was applied to determine whether
there were significant differences among groups. For post hoc analysis, Tukey test
was used. Results: There was statistically significant difference between groups 1 and 2 (p = 0.003),
1 and 3 (p = 0.008), 1 and 4 (p = 0.000) and 1 and 5 (p = 0.000). The group in
which only brushing was performed (Group 1) showed deeper enamel lesion. Conclusion: Pro Seal sealant alone or combined with brushing and/or brushing and the use of a
mouthwash with fluoride was more effective in protecting enamel, in comparison to
brushing alone.
Objetivo: Avaliar a prevalência de lesões orais em usuários de prótese dentária. Material e método: 110 usuários de próteses dentárias foram avaliados quanto ao sexo, faixa etária, tipo de prótese, tempo de uso de prótese e tempo de uso da prótese atual, frequência e métodos de higienização bucal e da prótese, uso noturno da prótese e consumo de bebidas alcoólicas e fumo. Para coleta dos dados realizou-se o exame clínico dos participantes e posterior orientação de higiene bucal e da prótese. Resultado: 34,6% dos usuários de prótese exibiram algum tipo de patologia, sendo a estomatite protética (27,3%) a mais prevalente. 2,7% dos participantes desenvolveram queilite e 4,6% uma associação de estomatite e queilite. Não houve diferença significativa entre os sexos quanto à presença de lesão. 46,4% dos usuários apresentavam higiene bucal deficiente e desses 54,9% possuíam algum tipo de lesão bucal. A frequência de higienização demonstrou ser um dos fatores determinantes no processo de desenvolvimento de lesões. 71,9% dos participantes relataram fazer uso noturno da prótese. 30% dos que bebem e 30% dos fumantes ativos possuíam lesão bucal. Conclusão: Há ainda um grande número de pessoas acometidas por lesões orais de simples diagnóstico e intervenção. Assim, faz-se extremamente necessário a contínua orientação, conscientização e acompanhamento profissional da população para uma melhor qualidade de vida.Descritores: Prótese Dentária; Prevalência; Mucosa Bucal; Patologia Bucal.
