Abstract

ABSTRACT
Introduction: The revolution in the aesthetic industry occurred due to the increased awareness of the patients about the minimal invasive aesthetic treatments. Bleaching is considered one of the most popular non-invasive cosmetic treatment done to lighten tooth shade beyond its natural color.
Objective: To compare between color shade stability following the application of 3 bleaching techniques, (light-activated bleaching, chemical activated bleaching and LASER activated bleaching) immediately 24 hours after application.
Procedures: Three different groups each of thirteen patients. Patient’s assignment to each group was done randomly by using random allocation. On Group A laser bleaching J.W. Power Bleaching NEXT. Group B, light-activated bleaching. While on Group C, chemical activated bleaching (Dash Philips-bleaching system 30% hydrogen peroxide) was applied. By using a sealed coded opaque envelope containing the treatment protocol of the subject, the allocation concealment was done. The envelope was only revealed on the day of bleaching. Assessment of the outcomes took place for teeth shade preoperatively, and post-operative, using a spectrophotometer.
Results: The results of this study were as follows: there was no significant difference in color change or stability between the three assigned groups.
Conclusion: The bleaching techniques tested in the current study protocols resulted in similar color change results tested immediately 24 hours postoperatively.
