Children/adolescent's orodental structures are different in anatomy and physiology from that of adults, therefore require special attention for bleaching with oxidative materials. Hydroxyl radical (OH(.)) generation from bleaching agents has been considered directly related to both its clinical efficacy and hazardous effect on orodental structures. Nonetheless bleaching agents, indirectly releasing hydrogen peroxide (H2O2), are considered safer yet clinically efficient. Apart from OH(.), perhydroxyl radicals (HO2(.)) too, were detected in bleaching chemistry but not yet in dentistry. Therefore, the study aims to detect the OH(.) and HO2(.) from bleaching agents with their relative integral value (RIV) using (31)P nuclear magnetic resonance ((31)PNMR) spectroscope.
