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

Abstract

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 the BlancTis Forte whitening agent for 2 hours twice a day for 4 weeks. As a control, Whitening Effect Pen (LG) containing 3% hydrogen peroxide was used by 20 volunteers using the same protocol. The change in shade (ΔE*, color difference) was measured using Shadepilot TM (DeguDent) before, during, and after bleaching (2 weeks, 4 weeks, and postbleaching 4 weeks). A clinical examination for any side effects (tooth hypersensitivity or soft tissue complications) was also performed at each check-up. The following results were obtained.1. Both the experimental and control groups displayed a noticeable change in shade (ΔE) of over 2. No significant differences were found between the two groups (p > 0.05), implying that the two agents have a similar whitening effect.2. The whitening effect was mainly due to changes in a and b values rather than in L value (brightness). The experimental group showed a significantly higher change in b value, thus yellow shade, than the control (p < 0 .05).3. None of the participants complained of tooth hypersensitivity or soft tissue complications, confirming the safety of both whitening agents.[J Kor Acad Cons Dent 34(2): [153][154][155][156][157][158][159][160] 2009]

Surface Damage and Bleaching Effect according to the Application Type of Home Tooth Bleaching Applicants

“…During in-office bleaching, a high concentration (30% or higher) of hydrogen peroxide is often used, although there tends to be strict safety protocols in direct interventions by dentists. In contrast, home bleaching is conducted in the absence of an expert, which may put the user at risk even if low-concentration hydrogen peroxide is used 10) .…”
