| ABSTRACTBackground: Bonding of restorative materials to tooth structure has become one of the prime objectives of modern dentistry. The purpose of this in vitro study was to evaluate and compare the shear bond strength of compomer material to dentin washed with three cleanser agent.Materials and Methods: Thirty freshly extracted adult human maxillary first premolars teeth were utilized in this study. Each tooth was sectioned horizontally exposing the dentin surface. According to the type of cleanser agent used to wash the dentin surface; the teeth were divided into three groups of ten teeth each: Group I chlorhexidine cleanser with compomer; Group II acetic acid with compomer; and Group III distal water with compomer. The measurement for evaluation the shear bond strength of compomer to dentin by using Zwick universal testing machineResults: The results showed that higher significant different between group I and group III also between group II and group III; however< there is no significant difference between group I and group II.Conclusions: This present in vitro study concludes that the shear bond strength of compomer material to dentin can be enhanced by washing the exposed dentin with cleanser agents’ chlorhexidine and acetic acid instead of distal water.Keywords: Shear bond strength, cleanser, compomer.
