Early And Late Impact of Diode LASER Activated Bleaching on Ultrastructure And Mineral Content of Surface Enamel in Rabbits
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 12
Abstract
The study directedto qualitatively analyze both early and late effect of Diode LASER activated bleaching on enamel surface of rabbit’s teeth. Materials and Method: Fifteen male rabbits were divided into three groups; control and two experimental. LASER bleaching gel was applied upon the labial surfaces of rabbits` incisors then activated by Diode LASER940nm.Teeth extracted after 24hrsin groupI and after one month in groupII. Examination of groups performed by Scanning Electron Microscope with Energy Dispersive X-ray Analyzer. Results; both experimental groups expressed structural and chemical alteration of enamel surface. Conclusion; Laser activated bleaching can cause irreversible denaturation of protein matrix and disturbance of chemical profile on rabbits' surface enamel. There is evidence of enamel surface weakness after LASER bleaching.
