Clinical study of shade improvement and safety of polymer-based pen type BlancTic Forte whitening agent containing 8.3% Carbamide peroxide

摘要: This clinical study evaluated the whitening effect and safety of polymer based-pen type BlancTis Forte (NIBEC) containing 8.3% carbamide peroxide. Twenty volunteers used agent for 2 hours twice a day 4 weeks. As control. Whitening Effect Pen (LG) 3% hydrogen peroxide was by 20 using same protocol. The change in shade (, color difference) measured (DeguDent) before, during, after bleaching (2 weeks, post-bleaching weeks). A examination any side effects (tooth hypersensitivity or soft tissue complications) also performed at each check-up. following results were obtained. 1. Both experimental control groups displayed noticeable () over 2. No significant differences found between two (p > 0.05), implying that agents have similar effect.2. mainly due to changes b values rather than L value (brightness). group showed significantly higher value, thus yellow shade,
