Coronally repositioned flap in gingival recession therapy

Abstract

The aim of this study was to evaluate surgical therapy of coronally repositioned flap (CRF) in solving the problem of gingival recession. Research involved 10 patients and CRP was used to cover denuded surfaces of 21 teeth. The success of the operation was evaluated through the measurement of the denuded root surfaces (DRS) and the estimation of the condition of the periodontal tissues measuring: clinical attachment level (CAL) clinical gingival level (CGL), keratinized gingival width (KGW), vestibulum depth (VD) and hygiene standards (PI and GI). The results obtained by this study indicate that on average 68% of denuded root surfaces are covered with CRF one year after the operation. Significantly more coronally dislocation of the CAL 2,68 mm and the CGL (2.02) mm were registered one year after the therapy. KGW has not significantly changed except at the first follow-up, when more narrow keratinized gingiva was registered (p<0,05). Measurement of the vestibulum depth (VD) ascertained a significant reduction of the value of this parametar at all follow-ups (p<0.001) and one year after the operation (p<0.05). The coverage of denuded teeth surfaces enables adequate maintenance of oral hygiene, which has a positive effect on the decrement of the amount of dental plaque (PI p<0.001) and mitigates gingival inflammation (GI p<0.001) in the postoperatiave period.
