Chemomechanical caries removal in primary molars : evaluation of marginal leakage and shear bond strength in bonded restorations--an in vitro study.

To evaluate and compare the efficiency, marginal leakage and shear bond strength of Carisolv and Papacarie in primary molars. Freshly extracted 60 human carious primary molars were randomly divided into two experimental groups--Group I [caries removal by Carisolv] and Group II [caries removal by Papacarie]. The amount of time taken for complete caries removal was recorded using a stopwatch. After bonded restorations, both the experimental groups were further randomly subdivided into four experimental groups and subjected to marginal leakage and shear bond strength evaluation. Papacarie [337.67 +/- 18.13] was clinically more efficient than Carisolv [461.33 +/- 27.76] in removing caries with respect to time in seconds. 66.7% of teeth treated with Carisolv did not show any marginal leakage as compared to 20% with Papacarie. The mean [ +/- SD] shear bond strength of Carisolv [9.67 +/- 3.80] treated teeth was slightly more when compared to Papacarie [8.36 +/- 4.51]. Papacarie was clinically more efficient in caries removal but showed significantly more marginal leakage than Carisolv.
