Effect of carisolv and papacárie on theresin-dentin bond strength in sound andcaries-affected primary molars

ABSTRACT

Aim: This study evaluated the influence of different chemomechanical caries removal techniqueson the bond strength of an adhesive system to caries-affected and healthy dentin. Methods:Thirty healthy teeth were randomly divided into three groups Group 1 (control) no cariesremoval technique was applied; Group 2 chemomechanical technique using Carisolv®; andGroup 3 chemomechanical technique using Papacárie®Twenty caries-affected teeth were divided .into two groups Group 4 chemomechanical technique using Carisolv; and Group 5chemomechanical technique using Papacárie. The teeth received the application of an etch-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. Datawere 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 meanbond strength values than the other groups (p<0.05), but did not differ significantly from each other(p>0.05). G4 (6.228 ± 5.3435) and G5 (6.482 ± 3.2076) presented the lowest mean bondstrength values and were statistically similar to each other (p>0.05). Conclusions: Neither of thechemomechanical caries removal methods interfered in the resin-dentin bond strength. However,lower tensile bond strength was found to caries-affected dentin.
