Prevalence of complications after gingival recession coverage procedure-a retrospective cohort study

Abstract

Gingival Recession is one of the common esthetic problems reported by patients for which recession coverage procedures like either flap or gingival grafting techniques are routinely practiced with high predictability and outcome. However these procedures also endup in morbidities like bleeding, necrosis etc. Hence the aim of the present study is to assess the complications after the recession coverage procedure. A retrospective evaluation was conducted to find out subjects who had undergone the gingival recession coverage procedure between June 2019-March 2020 at the University Dental Hospital. For the included subject, data regarding complications if present, demographic factors, other clinical factors associated with the complication were extracted. Out of 23 subjects, the prevalence of complications after gingival recession coverage procedure is 60.8%. Out of this post operative bleeding was the highly prevalent complication (43.5%), followed by tissue necrosis (17.3%) associated with subepithelial connective tissue graft. There were no reports of postoperative infection. A significant association was found with class 3 Miller’s recession defect and tissue necrosis.(P=0.05, chi square analysis). However considering the retrospective nature of the study, future literatures must be emphasised to analyse better patient outcomes and minimise the complications.
