Effect Of Various Prior Desensitization methods on Post Operative Sensitivity and colour stability induced due to In-Office Bleaching - A clinical Randomized control study

The study evaluated the effectiveness of Low-Level Laser Therapy (LLLT), Gluma Desensitizer, and Ultra EZ Gel in reducing postoperative sensitivity after in-office bleaching. Twenty-seven patients were randomly divided into three groups. Sensitivity was measured using the VAS at multiple time points, and tooth shade was assessed before and after bleaching. Results showed that LLLT was most effective in minimizing sensitivity, followed by Gluma, with Ultra EZ showing the highest sensitivity scores. All groups achieved significant whitening, with LLLT providing slightly superior shade stability. The study concluded that LLLT is the most effective method for reducing sensitivity while maintaining bleaching efficacy, with Gluma and Ultra EZ being less effective but still beneficial.
