CECCHIN, Doglas et al. Effect of carisolv and papacárie on the resin-dentin bond strength in sound and caries-affected primary molars. Braz. J. Oral Sci. [online]. 2010, vol.9, n.1, pp. 25-29. ISSN 1677-3225.

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 divided into 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 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. 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 bond 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 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.
