BACK GROUND: This study was undertaken to compare the two different surgical techniques for Gingival depigmentation in 20 patients. And evaluated quantitatively and qualitatively the percentage of Regimentation in 6 months follow up period MATERIALS AND METHODS: Totally 20 systemically healthy patients aged between 18- 40 yrs consists of 18 males and 2 females were enrolled in this study patients were randomly divided in to two groups. Each group consist of 10 patients, Group A was treated with conventional scalpel technique and Group B with semiconductor diode laser (BiolaseĀ®) was used at 810nm wave length with contact mode. All the patients were recalled on 10 days, 30days, 60days, 90days, and 180days, post operatively. Standardized photographs were taken pre-operatively as well as post-operatively. Patients were evaluated for pain, discomfort and percentage of Repigmentation using image analysis soft ware J 1.42 q (National Institute of Health) RESULTS: There is a statistically significant difference in the scalpel group with (p=0.005) and there is no statistically significant difference in laser group (p=0.20) pre and post-operatively. Statistically significant differences noted between scalpel group and laser group. CONCLUSION: The percentage of Repigmentation is less in scalpel technique when compared with diode laser technique and hence extending the longevity of the scalpel depigmentation procedure. But the laser technique showed ease of handling and patient comfort. However drawback of this study is less number of subjects, shorter follow up period, Histological and Histochemical assessment of Melanocytes activity were not carried out.
