Previous issue date: 2015-01-23 / Funda??o de Amparo ? Pesquisa do Estado do Rio Grande do Sul - FAPERGS / The objectives of this in vitro study were: 1) to evaluate the surface roughness of a composite resin covered by sealing surface containing inorganic filler or not, subject to brushing; 2) to analyze, with the aid of scanning electron microscopy, the presence of the sealant after 48 months of simulated toothbrushing; 3) verify that the type of toothpaste reduces the useful life of sealants; 4) verify the presence of inorganic filler prevents the increase in roughness forward to brushing. For this, 54 samples were made of composite resin and divided into nine groups: G1 - without composite sealant (control); G2 - Sealant Fortify, toothpaste Colgate Professional Whitening; G3 - Fortify, Colgate Total Clean Mint; G4 - Fortify, Edel White Whitening; G5 - Fortify, Edel White Gum Care; G6 - Fortify Plus, Colgate Whitening Professional; G7 - Fortify Plus, Colgate Total Clean Mint; G8 - Fortify Plus White Whitening Edel; G9 - Fortify Plus, Edel White Gum Care and analyzed the simulated periods of brushing (12,24, 36 and 48 months). Reading roughness was performed at baseline and after each simulated toothbrushing period, using a surface roughness (SJ 201 Mututoyo).Two specimens of each group were observed by SEM. The data were submitted to ANOVA and Tukey's test (5%). There was a significant difference between the two sealants, with the sealant Fortify Plus rougher. Among the toothpaste, Colgate Clean Mint associated with Fortify Plus sealant obtained the higher roughness values. Lower values were associated with Gum Care Fortify sealant. The protective layer formed by the sealant remained partially by the end of 48 months of brushing, maintaining the smoothness of the composite. We conclude that both sealants guaranteed protection of the composite, and the Fortify Plus rougher for all assessed toothpastes. Clinical significance: The roughness of the surface sealant is changed for different toothpastes and different times of brushing and the addition of inorganic filler in sealants promotes different performances in relation to surface roughness. / Os objetivos deste estudo in vitro foram: 1) avaliar a rugosidade de superf?cie de uma resina composta coberta por selantes de superf?cie contendo carga inorg?nica ou n?o, submetidas ? escova??o simulada; 2) analisar, com aux?lio da microscopia eletr?nica de varredura, a presen?a dos selantes ap?s 48 meses de escova??o simulada; 3) verificar se o tipo de dentifr?cio diminui o tempo de vida ?til dos selantes; 4) verificar se a presen?a de carga inorg?nica previne o aumento da rugosidade frente ? escova??o. Para isto, foram confeccionadas 54 amostras de resina composta e divididas em nove grupos: G1 ? comp?sito sem selante (controle); G2 ? Selante Fortify, dentifr?cio Colgate Professional Whitening; G3 ? Fortify, Colgate Total Clean Mint; G4 ? Fortify, Edel White Branqueador; G5 ? Fortify, Edel White Gum Care; G6 ? Fortify Plus, Colgate Professional Whitening; G7 ? Fortify Plus, Colgate Total Clean Mint; G8 ? Fortify Plus Edel White Branqueador; G9 ? Fortify Plus, Edel White Gum Care e analisados nos per?odos simulados de escova??o de 12, 24, 36 e 48 meses. A leitura da rugosidade foi realizada no baseline e ap?s cada per?odo de escova??o simulada, utilizando um rugos?metro de superf?cie (SJ 201 Mututoyo). Dois corpos de prova de cada grupo foram observados em MEV.Os dados foram submetidos ? ANOVA e Teste de Tukey (5%). Verificou-se diferen?a significativa entre os dois selantes, sendo o selante Fortify Plus mais rugoso. Entre os dentifr?cios, o Colgate Clean Mint associado ao selante Fortify Plus obteve os maiores valores de rugosidade. Os menores valores observados foram com Gum Care associado ao selante Fortify. A camada de prote??o formada pelos selantes permaneceu parcialmente at? o final de 48 meses de escova??o, mantendo a lisura do comp?sito. Conclui-se que ambos os selantes garantiram prote??o da resina composta, sendo o Fortify Plus mais rugoso para todos os dentifr?cios avaliados. Signific?ncia cl?nica: A rugosidade dos selantes de superf?cie ? alterada em fun??o de diferentes dentifr?cios e diferentes tempos de escova??o e a adi??o de carga inorg?nica nos selantes promove desempenhos diferentes em rela??o ? rugosidade superficial.
