Background: This study aimed to compare the clinical efficacy of Coronally Advanced Flap (CAF) with a Modified Semilunar Coronally Advanced Flap (MSCAF) in the treatment of Miller’s class I and class II Gingival recession. Materials and methods: A double-blinded, simple, randomized, prospective, split-mouth clinical study with a total of 12 patients was segregated randomly into two sites. Site I was treated with coronally advanced flap technique. Site II was treated with modified semilunar coronally advanced flap technique. For each patient, both the sites Was recorded with clinical parameters. Results: In both sites, statistically significant changes in recession depth and clinical attachment level were seen from baseline to 24th week. No statistically significant difference was seen between the two groups at any time period. In site I,complete root coverage (CRC) was accomplished in five teeth (43.8%) with defects. In site II complete root coverage (CRC) was achieved in four teeth (33.3%) whose defect was treated. Conclusion: From the findings of this clinical investigation CAF or MSCAF can be utilised successfully to treat gingival recessions. For more accurate assessment of these techniques, more clinical trials are required.
