Effectiveness of fluoride sealant in the prevention of carious lesions around orthodontic brackets: an OCT evaluation.

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.

Resumo Objetivo: avaliar in vitro a eficiência da aplicação de selante fluoretado Pro Seal na prevenção de lesões de mancha branca ao redor de braquetes ortodônticos. Métodos: braquetes foram fixados na face vestibular de incisivos bovinos, formando os seguintes cinco grupos (n = 15) de acordo com a exposição a substâncias de higiene bucal e a aplicação do selante de esmalte: 1) controle - realizada apenas escovação; 2) controle - escovação + utilização de enxaguante bucal com flúor; 3) apenas aplicação de selante Pro Seal (Reliance Orthodontic Products, Itasca, Ill); 4) Pro Seal + escovação; 5) Pro Seal + escovação + bochecho. Os grupos experimentais alternaram entre ciclagem de pH e os procedimentos descritos. Todos os espécimes foram mantidos, durante todo o experimento, à temperatura de 37°C. Tanto a escovação quanto a imersão nas soluções foram realizadas em um intervalo de tempo de 1 minuto, seguidas por lavagem em água deionizada, três vezes por dia, durante 28 dias. Após isso, realizou-se avaliação utilizando Tomografia por Coerência Óptica (OCT) do tipo espectral (Ganymede OCT/Thorlabs, Newton, EUA). Em cada grupo, foi realizado um exame em varredura da área de mancha branca (em torno da região onde foram colados os braquetes), assim como a aferição da profundidade das lesões de cárie. A análise de variância (ANOVA) foi aplicada para determinar se houve diferenças significativas entre os grupos. Para o testepost hoc, foi utilizado o teste de Tukey. Resultados: houve diferença estatisticamente significativa entre os grupos 1 e 2 (p = 0,003), 1 e 3 (p = 0,008), 1 e 4 (p = 0,000) e 1 e 5 (p = 0,000). O grupo onde apenas escovação foi feita (Grupo 1) mostrou lesão do esmalte mais profunda. Conclusão: o selante ProSeal sozinho ou combinado com escovação e/ou escovação e uso de bochechos com flúor foi eficaz em proteger mais do que apenas escovar esmalte.

Inter-relação da periodontia e outras especialidades odontológicas – revisão deliteratura / Interrelation between Periodontics and others dental specialties – Literature review

A Odontologia vem se desenvolvendo muito nos últimos anos e tem mostrado uma preocupação cada vez maior com a promoção da saúde do paciente, realização de diagnósticos mais corretos, atuação na prevenção e tratamentos mais modernos e efetivos priorizando a saúde e satisfação do paciente e segurança e conhecimento para o profissional. Este estudo, de natureza bibliográfica, tem como objetivo revisar a literatura de forma a elucidar a inter-relação entre a Periodontia e outras especialidades odontológicas, como a Prótese, a Ortodontia e a Dentística. O material empírico teve como base publicações oriundas de livros e artigos produzidos de 1989 a 2011, constou como base de dados o Scielo, LILACS e Bireme, utilizando os seguintes descritores: Dentística, Periodontia e Prótese Dentária. Conclui- se, portanto, que é fundamental a existência de uma parceria concreta e ativa entre as diversas áreas de especialidades odontológicas, em especial, com a Periodontia, já que esta representa a base do tratamento odontológico, por ser o alicerce de sustentação do dente ou do implante dentário

Dentistry has developed in recent years, and has shown an increasing concern with the promotion of health of the patient, performing more accurate diagnosis, prevention and treatment work in the most modern and effective prioritizing health and patient satisfaction and safety and knowledge for the professional. This study, bibliographic in nature, aims toreview the literature in order to elucidate the interrelationship between periodontal and other dental specialties, such as Periodontics, Orthodontics and Dentistry. The empirical material is formed in publications from books and articles produced from 1989 to 2011, as a database comprised the LILACS, BIREME and SciELO, using the following keywords: Dentistry, Periodontics, Dental Prosthesis. We conclude, therefore, it is essential to have a concrete and active partnership between the various areas of dental specialties, in particular, Periodontics, as this represents the basis of dental treatment, to be the bedrock of support of the tooth or dental implant.
