Aim: The purposes of this study were to determine the influence of chemical-cure adhesives and light-cure adhesives on the stain susceptibility after debonding and the effects of different clean-up procedures on the stain susceptibility after debonding. Materials and methods: Seventy teeth specimens were randomly divided into seven groups of 10 teeth-Group 1: no bonding (control group), Group 2: bonding with light-cure adhesive, i.e. transbond XT and finishing with carbide bur after debonding, Group 3: bonding with transbond XT and finishing with carbide bur and polishing with pumice and rubber cup after debonding, Group 4: bonding with transbond XT and finishing with Sof-Lex disks after debonding, Group 5: bonding with chemical-cure adhesive, i.e. unite and finishing with carbide bur after debonding, Group 6: bonding with unite and finishing with carbide bur and polishing with pumice and rubber cup after debonding, Group 7: bonding with unite and followed by debonding and finishing with Sof-Lex disks after debonding. The color parameters were measured on spectrophotometer before bonding and after methylene blue staining following debonding and clean-up procedures. Results: Comparing each clean-up procedure in both adhesive systems, color change for Group 6 (19.59) was significantly higher than Group 3 (15.00) (p < 0.05). No significant color change was observed between control group (14.01) and Group 3 (15.00) (p > 0.05). Conclusion: Chemical-cure adhesive showed higher stain susceptibility than light-cure adhesive in all clean-up procedures. Both adhesives would show less stain susceptibility with polishing step with rubber cup and pumice.
