Aim. This was to compare fluorescence values of dentine remaining after caries removal using chemomechanical systems and conventional rotary methods. Study design: In vitro study. Methods: 30 extracted primary teeth with proximal carious cavities were divided into three groups according to caries removal method: Carisolv®, Papacarie® and conventional low speed rotary burs. Carious (initial) and remaining (final) dentine evaluations were assessed by visual-tactile examination and DIAGNOdent. Transversal microhardness (TMH) of remaining dentine was evaluated. Fluorescence and TMH values were submitted to two-way ANOVA and the post hoc Tukey test (α = 0.05) and Pearson’s linear correlation. Results: Two-way ANOVA revealed that fluorescence values were similar between conventional rotary excavation, Carisolv® and Papacarie® groups (p = 0.0542). No statistically significant differences (p = 0.1147) were found to TMH values. No correlation was found between fluorescence and TMH values (r = −0.0273). Conclusion: All caries excavation methods resulted in similar remaining dentine fluorescence values. No correlation was found between fluorescence values and TMH of remaining dentine.
