AbstractBACKGROUND: This study compared the chemical, morphological and microhardness changes in carious dentine following application of NaOCl-based (Carisolv), papain-based (Papacarie) chemomechanical caries removal agents with conventional rotary method. METHODS: Thirty-two carious and eight non-carious human permanent molars were used. The carious molars were randomly distributed into four groups: Group 1 (positive control) - molars were left without caries removal; Group 2 - caries excavated with rotary method; Group 3 - caries excavated with Carisolv; Group 4 - caries excavated with Papacarie. Group 5 (negative control) consisted of eight sound molars. After caries excavation, all specimens were prepared for chemical, morphological analysis and Vickers hardness testing. RESULTS: EDX analysis showed no significant difference in Ca wt%, P wt% and Ca/P ratio among Groups 2 to 5. Vickers hardness of dentine from Groups 3 and 4 was significantly lower (p < 0.05) than for Groups 2 and 5. The use of Papacarie resulted in a dentine surface without smear layer and patent tubules, while Carisolv resulted in a dentine surface exhibiting two patterns: (1) the presence of smear layer or (2) patent tubules with partial smear layer formation. CONCLUSIONS: Papain-based (Papacarie) chemomechanical caries removal method is a reliable alternative to conventional rotary and NaOCl-based (Carisolv) caries removal.
