Comparison of semilunar coronally advanced flap alone and in combination with button technique in the treatment of Miller′s Class I and II gingival recessions: A pilot study

Background: Gingival recession (GR) is one of the most common esthetic and functional concerns associated with periodontal disease. A variety of surgical procedures has been introduced to the field of cosmetic periodontology for the treatment of GR. Aim: To evaluate and compare the clinical outcome of semilunar coronally advanced flap (SCAF) with and without button technique in the treatment of Miller′s Class I and II GRs. Study Design: A total of 12 subjects with bilateral single Miller′s Class I and II recession were selected for the study. Split mouth design was used. Materials and Methods: Surgical sites were randomly divided into test and control groups. In control sites, SCAF alone was done whereas in test site, a combination of SCAF and button technique was performed. The clinical parameters including GR, periodontal pocket depth, clinical attachment level (CAL), and width of keratinized gingiva were recorded at baseline and 6 months postsurgery. Data so collected were put to statistical analysis. Statistical Analysis: Student′s t-test was used to find significance of parameters between baseline and 6 months. For inter-group comparisons paired t-test was performed. Results: Statistically significant improvements were recorded in both groups from baseline to 6 months. Inter-group comparison yielded statistically significant differences in GR and CAL in favor of test group. Conclusion: Combination of SCAF and button technique resulted in statistically significant improvements in clinical parameters as compared to SCAF alone. Future clinical studies with much larger sample size and longer follow-up periods are warranted.
