Materials and Methods: The present double-blind, randomized, controlled clinical trial studied 12 patients who had 2 mm or less keratinized gingiva bilaterally around mandibular premolars. The 6-month width of keratinized tissue, periodontal parameters (preoperatively and 1, 3, and 6 months postoperatively), color match, pain, and total surgical time were measured. Results: The mean dimensional change of keratinized gingiva 6 months postoperatively was 4.1±0.7 mm for FGG and 8±1.7 mm for CM. Periodontal parameters were not affected in the two groups. The CM group had a significantly lower pain, experienced less surgery time, and gained better aesthetics compared to the FGG group. Conclusion: CM appears to be a suitable substitute for FGG in procedures designed to increase keratinized tissue around teeth. It has remarkable benefits, such as acceptable keratinized tissue gain, less pain, less surgical chair time, and better aesthetics. 08 12 2020 10.18502/fid.v17i1.3965 http://18.184.16.47/index.php/fid/article/view/3965 http://18.184.16.47/index.php/fid/article/download/3965/3034 http://18.184.16.47/index.php/fid/article/download/3965/3034 https://fid.tums.ac.ir/index.php/fid/article/view/3226 https://publish.kne-publishing.com/index.php/fid/article/view/3965
