Wound Healing Evaluation after Gingival Depigmentation Using Ceramic Soft Tissue Trimming Bur Versus Diode Laser: Randomized Clinical Trial

Aim: To assess if ceramic soft tissue trimming bur equally efficient as a gingival depigmentation tool versus diode laser. Materials and Methods: A total of 30 patients who needed depigmentation procedures in upper jaw. In this study we used split mouth design by dividing the upper jaws into 2 equal halves. In Group 1, The soft tissue trimming bur performed the depigmentation treatment. The depigmentation process in Group 2 was completed using a laser. Results: Group I showed a significant difference at follow-up visits (p<0.001). Value recorded at 1 month (100.00±0.00) had the greatest mean value then 7 days (82.43±8.42) while value recorded at baseline (0.00±0.00) showed the least mean value. Pairwise assessments showed significantly different values (p<0.001). Group II had a significant variation at follow-up then 7 days (82.94±8.02) while at baseline (0.00±0.00) showed the least mean value. Pairwise comparisons showed significantly different values at different intervals (p<0.001). Conclusion: The outcomes of the two methods of treatment were nearly identical. Techniques like as ablation and abrasion were sufficient to provide satisfactory aesthetic results and a satisfactory healing process free from pain or infection. Compared to diode lasers, soft tissue trimmers are less expensive and easier to operate.
