Antibacterial activity of 10% carbamide peroxide bleaching agents

Effect of 15% Carbamide Peroxide on the Surface Roughness and Adhesion of Streptococcus mutans to Microhybrid Composite Resin and Giomer

“…29 Bleaching might result in a decrease in the adhesion of salivary proteins on the surface of bleached materials through factors containing peroxide, and it appears it might affect the adhesion of cariogenic bacteria, such as S. mutans and S. sobrinus. 36 Gurgan et al 42 reported an antibacterial effect for 10% carbamide peroxide, consistent with the results of the present study. However, in a study by Montanaro et al, 5 none of the bleaching agents was able to decrease the number of the microorganisms tested.…”

“…Some other studies have shown an increase in BA to bleached enamel. 17,19,42 Mor et al 4 showed that S. mutans exhibited a stronger adhesion to bleached composite resin surfaces, reporting that bleaching results in some microsurface characteristics on hard surfaces in the oral cavity, paving the way for adhesion of S. mutans. Sucrose was used in that study, which has an important role in the adhesion of S. mutans.…”

Nonvital Tooth Bleaching: A Review of the Literature and Clinical Procedures

“…Currently, the most popular commercial bleaching preparations containing carbamide peroxide usually also include glycerin at different concentrations because this makes it more chemically stable compared with hydrogen peroxide. Ten percent carbamide peroxide bleaching agents also demonstrated higher antibacterial effect than a 0.2% chlorhexidine solution (60).…”

A study of in vivo degradation of two vital home bleaching gels

“…The antibacterial properties of whitening gels have been proven [21][22][23] . For this study, individuals who had a Silness and Löe index≥1 24) were excluded to avoid reactions of H2O2 with microorganisms that cause gingivitis and periodontitis.…”
