title: Fluorescence of primary dentine after chemomechanical and conventional rotary excavation.
abstract: OBJECTIVE
  This was to compare fluorescence values of dentine remaining after caries removal using chemomechanical systems and conventional rotary methods.
  
  
  METHODS
  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 (alpha = 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).
  
  
  CONCLUSIONS
  All caries excavation methods resulted in similar remaining dentine fluorescence values. No correlation was found between fluorescence values and TMH of remaining dentine.
