Aim and Objective : The aim of this study is to evaluate the positional changes that occur in mucogingival line following the use of subepithelial connective tissue graft (SCTG).Materials and Methods : In 19 Miller class I or II Toy Playsets gingival recession defects, distance between mucogingival line (MGL) and cemento-enamel junction, also width of keratinized and attached gingiva, and clinical attachment level were measured.SCTG were used for covering the exposed roots.
A fore mentioned parameters were repeated at 3, 6 and 12 months after surgery and alterations were measured.Paired t test was used to analyze the results.Results : MGL had been moved in coronal direction (4.
39 ± 0.77 mm on average) during surgical approach.After 1 year, MGL shifted 2.
11 ± 0.7 mm apically.In accordance with this apical shift, a significant increase in the width of keratinized and attached gingival width (2.
89 ± 0.63 mm and 2.82 ± 0.
5 mm, respectively) was seen (P < 0.05).Conclusion : MGL tended to revert back to its original position following the use of SCTG, Urinals and this reversion is accompanied with an increase in the keratinized and attached gingival width.
