Alterations in Location of the Mucogingival Junction 5 Years After Coronally Repositioned Flap Surgery

Background: The aim of this clinical study was to evaluate whether the mucogingival junction (MGJ) reverts back towards its original location following coronally repositioned flap (CRF) procedure over a 5‐year follow‐up period. Methods: Thirteen systemically healthy patients with 26 Miller Class I buccal gingival recessions were treated using the CRF technique. At baseline, and 1, 6, 12, and 60 months after surgery, location of gingival margin (LGM), probing depth (PD), clinical attachment level (CAL), width of keratinized gingiva (WKG), and location of mucogingival junction (LMGJ) were recorded. The alterations in the clinical measurements at the different evaluation times were analyzed using the Friedman and the repeated measure analysis of variance (ANOVA) tests, where applicable. Degree of association between continuous variables was calculated by the Pearson's correlation coefficient. Results: The mean percentage of root coverage obtained at the end of 1 month was 68.26% ± 30.37% (P
