ABSTRACT
Objective: The aim of this study was to evaluate the incompatibility between simplified adhesive systems and dual-cure resin cement by means of marginal micro-leakage testing. Methods: Standardized cavity preparations were performed in 30 bovine teeth. The adhesive systems Adper Scotchbond Multipurpose Plus (3M ESPE, St. Paul, MN, USA) - Group A, Excite (Ivoclar/Vivadent, AG, Liechtenstein) - Group B, and Adper Prompt L-Pop (3M ESPE, St. Paul, MN, USA) - Group C, were applied and the cavities were filled with dual-cure resin cement (Enforce - Denstply, Milford, DE, USA). The samples were submitted to five hundred thermal cycles, after which they were immersed in 2% buffered methylene blue. Results: Group A presented the lowest mean percentage of micro-leakage (3.34%), followed by Group B (13.60%) and Group C (48.33%). Significant differences were found among the groups after the application of the Kruskal-Wallis statistical test (P=0.00). Conclusion: The highest mean marginal micro-leakage values were shown with the use of the one-bottle etch-and-rinse adhesive system and the all-in-one self-etch system, which demonstrates the incompatibility between these materials.
RESUMO
Objetivo: Avaliar a incompatibilidade entre sistemas adesivos e cimento resinoso dual através de teste de microinfiltração marginal. Métodos: Foram realizados preparos cavitários padronizados em 30 dentes bovinos divididos em 3 grupos: A) Adper Scotchbond Multipurpose (3M ESPE, St. Paul, MN, USA); B) Excite (Ivoclar/Vivadent, AG, Liechtenstein) e C) Adper Prompt L-Pop (3M ESPE, St. Paul, MN, USA). Após aplicação dos adesivos, as cavidades foram preenchidas com cimento resinoso dual Enforce (Denstply, Milford, DE, USA), submetidos à ciclagem térmica (500 ciclos) e imersos em azul de metileno 2% tamponado. Resultados: O grupo A apresentou os menores percentuais de microinfiltração (3,34%), seguido pelo grupo B (13,60%) e pelo grupo C (48,33%). Após aplicação do teste estatístico Kruskal-Wallis, foram detectadas diferenças estatisticamente significativas entre os três grupos (P=0.00). Conclusão: Houve incompatibilidade na associação entre os sistemas adesivos, convencional de dois passos (Excite, Ivoclar/Vivadent, AG, Liechtenstein) e autocondicionante de passo único (Adper Prompt L-Pop (3M ESPE, St. Paul, MN, USA), e o cimento resinoso dual Enforce (Denstply, Milford, DE, USA).
