Abstract

Aim:  The aim of this study was to assess the cuspal deflection related to different adhesive techniques called total bonding and selective bonding techniques in class II composite restorations in human premolar teeth. Materials and methods: Forty freshly extracted human premolar teeth were prepared with class II cavities and then restored with composite (esthetx HD A2, USA) using etch-and-rinse (Prime and Bond ,Dentsply USA) or self etch (One Coat, coltene and whaledent, Switzerland) adhesive systems under different bonding techniques (total bonding and selective bonding). The cuspal distance was measured before and after the restorative procedure, and the difference was recorded as mean cuspal deflection. The results were subjected to statistical analysis by ANOVA and Scheff’s multiple comparison tests. Results: For both adhesive systems, the teeth restored with selective bonding technique showed lower values of cuspal movement. Conclusions: Both the adhesive techniques tested were not able to prevent the cuspal movement. However, selectively bonded class II composite restorations demonstrated lower values of cuspal movement comparing with total bonding technique.
