Background: different methods can be used to remove tissue during gingivectomy and produce a good gingival margin, the most common is the conventional gingivectomy which is done by the use of scalpel, now a day’s Laser is widely spread and can be used to perform surgeries. Materials and methods: 50 patients divided into two equal groups, Group 1 gingivectomy was done by Diode Laser, Group 2 gingivectomy was done by scalpel, plaque and gingival index were measured at 1st, 2nd and 3rd visit, swab were taken and sent foe detecting bacterial growth and biopsy were taken for histopathological examination. Group 1 show no significant differences in plaque and gingival means between the visits, the bacteriological examination showed no growth of bacteria and histological examination revealed less inflammatory cells than Group 2. Group 2 show significant differences in plaque and gingival indices between the visits.  Though scalpel remains the gold standard choice in gingivectomy but Diode laser may have some advantages over it. https://biomedpharmajournal.org/vol10no4/diode-laser-versus-scalpel-gingivectomy/ Brushing Diode Gingivectomy Laser Scalpel
