Abstract

AimTo evaluate the microtensile bond strength of teeth restored with packable composite after removing caries with three chemomechanical caries removal agents (Carisolv, Papacarie and Carie-care) and also to analyze its effect on chemical composition of dentin using energy-dispersive X-ray (EDX) analysis.DesignA total of 40 carious molars with 1 to 1.5 mm of remaining dentin were selected and divided into four groups of 20 each. Group I (control)—bur, group II—Carisolv, group III—Papacarie, group IV—Carie-care. A total of 15 samples from each group were restored with composite; 1 mm thick sections were made and were debonded under tensile load. Remaining five samples from each group were subjected to EDX for elemental analysis of dentin surface.ResultsNo statistically significant difference in the bond strength values and Ca/P ratio was observed between control group and three chemomechanical agents tested in the study.ConclusionNone of the chemomechanical agents tested in the study adversely affected the bond strength of composite resin to caries-affected dentin. Therefore, newer papain-based chemomechanical agent Carie-care can be considered as an equally effective economical alternative to commonly used agents Carisolv and Papacarie.How to cite this article: Nair S, Nadig RR, Pai VS, Gowda Y.

Summary

Introduction

The conventional method of caries removal technique, is quick and efficient, may result in unnecessary removal of the healthy and even the affected dentin that shows ability to remineralize. It may be associated with pain and patient discomfort, necessitating administration of local anesthesia.[3,4,5] To address these limitations, minimally invasive complementary caries removal methods were proposed like chemomechanical techniques, air abrasion with aluminum oxide or glass particle, sonoabrasion, ultrasonic instrumentation, and lasers. Because of its disadvantages like time consumption, unpleasant smell, and taste, later in 2003, a Brazilian formulation for chemomechanical caries removal was introduced into the market under the trade name Papacarie (Formula e Acao, Sao Paulo, SP, Brazil) which is based on papain.[7,8,9]
