Abstract
Aim: This study evaluated the influence of different chemomechanical caries removal techniques on the bond strength of an adhesive system to caries-affected and healthy dentin. Methods: Thirty healthy teeth were randomly dividedinto three groups: Group 1 (control): no caries removal technique was applied; Group 2: chemomechanical technique using Carisolv ®; and Group 3: chemomechanical technique using Papacárie®. Twenty caries-affected teeth were divided into two groups: Group 4: chemomechanical technique using Carisolv; and Group 5: chemomechanical technique using Papacárie. The teeth received the application of anetch-andrinse adhesive system, were restored with composite resin, and then sectioned to obtain 4 hourglassshaped slabs from each specimen, which were subjected to a microtensile bond strength test. Data were analyzed statistically by ANOVA and Tukey’s test (a=0.05). Results: G1 (13.387 ± 6.1074), G2 (18.123 ± 3.2611) and G3 (12.781 ± 4.5652) presented statistically significant higher mean bondstrength values than the other groups (p0.05). G4 (6.228 ± 5.3435) and G5 (6.482 ± 3.2076) presented the lowest mean bond strength values and were statistically similar to each other (p>0.05). Conclusions: Neither of the chemomechanical caries removal methods interfered in the resin-dentin bond strength. However, lower tensile bond strength was found to caries-affected dentin. Keywords: chemomechanicalcaries removal; microtensile bond strength; etch-and-rinse adhesive system.

Introduction
Current dental restorative concepts are characterized by an increasing effort toward less invasive treatment of carious lesions 1. Because it appears that only soft, wet dentin is heavily contaminated with bacteria 2 , any technique that effectively removes such infected dentin should be adequate to arrestthe carious process, allowing altered dentin capable of being remineralized, to remain 3. Chemomechanical systems have been discussed as an alternative to conventional rotary systems 4-5. Carisolv ® (MediTeam Dental AB, Sävedalen, Sweden) is used to remove soft carious dentin with the aid of special curettes. It can be applied in adults and children, in many cases allowing treatment without theuse of anesthesia, and can even be used in patients with special needs 6. This

system consists of two gels: one containing 0.95% sodium hypochlorite (NaOCl), and the other containing three amino acids (glutamic acid, leucine and lysine), sodium chloride, carboxy-methyl-cellulose, sodium hydroxide and water 7. The effect of Carisolv is based on the action of NaOCl, which disintegrates the caries-affected dentin 8-9. The amino acids are used to...
