Resumo: Purpose: To evaluate the effect of chisel width on shear bond strength of composite to dental enamel. Methods: Sixty crowns of bovine incisors were embedded in acrylic resin, and their enamel surfaces were flattened and etched with 35% phosphoric acid. Single Bond (3M/ESPE) adhesive system and Z-250 (3M/ESPE) composite were used to build a cylindrical-shaped restoration perpendicular to the conditioned enamel flat surface. Specimens were divided into four groups and subjected to the shear bond strength testing using a chisel-shaped shearing blade with a 0.5, 1.0, 2.0, or 3.0 mm-width blunt edge in a universal testing machine at crosshead speed of 0.5 mm/min. Data on shear bond strength were analyzed by ANOVA and Duncan’s test (α=0.05). Results: Shear bond strength means for the experimental groups were: 0.5 mm – 19.66 MPa; 1 mm – 18.78 MPa; 2 mm – 16.77 MPa; 3 mm – 16.06 MPa. Bond strength was significantly different between the groups tested with chisels of 0.5 and 3 mm-width (P=0.045) showing an inverse relationship between shear bond strength and chisel width. Conclusion: The results suggest that shear bond strength varies as a function of chisel width. Key words: Dental materials; mechanical properties; shear strength

Metodologia: As coroas de 60 dentes incisivos bovinos foram incluídas em resina acrílica e as superfícies vestibulares de esmalte foram planificadas e condicionadas com ácido fosfórico a 35 %. O sistema adesivo Single Bond (3M/ESPE) e de resina composta Z-250 (3M/ESPE) foram utilizados para fabricar restaurações cilíndricas de resina composta perpendiculares à superfície plana do esmalte condicionado. Para o teste de cisalhamento, os espécimes foram submetidos ao ensaio mecânico com cinzéis de 0,5 mm, 1,0 mm, 2,0 mm ou 3,0 mm de largura da parte ativa romba, em uma máquina de ensaio universal à velocidade de 0,5 mm/min. Os dados obtidos foram analisados por análise de variância e teste de Duncan ao nível de significância de 5 %. Resultados: As médias de resistência de união ao cisalhamento dos grupos testados foram: 0,5 mm – 19,66 MPa; 1,0 mm – 18,78 MPa; 2,0 mm – 16,77 MPa; 3,0 mm –16,06 MPa. Houve diferença estatisticamente significativa entre os grupos de 0,5 e 3,0 mm (P=0,045), com uma relação inversa entre resistência de união ao cisalhamento e largura do cinzel. Conclusão: Os resultados sugerem que a resistência de união ao cisalhamento sofre influência da largura do cinzel utilizado no ensaio.
