Aim: Evaluation of marginal microleakage with SonicFillTM. Method and materials: In this in vitro experimental study, were sectioned thirty noncarious human molars in occluso-cervical direction. Class V cavities were prepared on the buccal or lingual surfaces of each tooth with gingival margin walls in enamel and dimensions: 4 mm mesiodistally, 3 mm occlusogingivally and 3 mm depth. The specimens were divided in 4 groups: group 1 - restored with SonicFillTM (Kerr/Kavo), group 2 - restored with FiltekTM Supreme XTE (3M ESPE), group 3 – the cavities were not restored; group 4 – restored with SonicFillTM (Kerr/Kavo). In groups 1, 2 and 4 the enamel is conditioned with 37% orthophosphoric acid and applied the self-etch adhesive system ClearfilTM SE BOND (Kuraray). The specimens were stored in distilled water at 37ºC for 7 days. Followed thermocycling: 500 cycles between 5ºC and 55ºC with a dwell time of 30 seconds. After immersed for 3 hours in a solution of 99mTc-Pertechnetate the radioactivity was assessed with a gamma camera. The nonparametric Kruskal-Wallis and Mann-Whitney test with Bonferroni correction at a significance level of 5% were used for the statistical analyses. Results: There are significative differences between the positive and negative control groups and between these and experimental groups (p <0.05). There are no statistically significant differences between the specimens restored with SonicFillTM and FiltekTM Supreme XTE. Conclusion: The new composite SonicFillTM and FiltekTM Supreme XTE didn’t show difference concern to the dye penetration. The SonicFillTM restorative system doesn’t show influence in what concerns to microleakage.2012-06info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesishttp://hdl.handle.net/10316/36329http://hdl.handle.net/10316/36329engPereira, Catarinainfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2022-01-20T17:48:50Zoai:estudogeral.uc.pt:10316/36329Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T20:45:32.375913Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
