Treatment of localized gingival recession using the free rotated papilla autograft combined with coronally advanced flap by conventional (macrosurgery) and surgery under magnification (microsurgical) technique: A comparative clinical study

摘要

Background:The aim of the present study was to evaluate and compare the conventional (macro-surgical) and microsurgical approach in performing the free rotated papilla autograft combined with coronally advanced flap surgery in treatment of localized gingival recession.Materials and Methods:A total of 20 sites from 10 systemically healthy patients were selected for the study. The selected sites were randomly divided into experimental site A and experimental site B by using the spilt mouth design. Conventional (macro-surgical) approach for site A and micro-surgery for site B was applied in performing the free rotated papilla autograft combined with coronally advanced flap. Recession depth (RD), recession width (RW) clinical attachment level (CAL.) and width of keratinized tissue (WKT.) were recorded at baseline, 3 months and 6 months post-operatively.Results:Both (macro- and microsurgery) groups showed significant clinical improvement in all the parameters (RD, RW, CAL and WKT). However, on comparing both the groups, these parameters did not reach statistical significance.Conclusion:Both the surgical procedures were equally effective in treatment of localized gingival recession by the free rotated papilla autograft technique combined with coronally advanced flap. However, surgery under magnification (microsurgery) may be clinically better than conventional surgery in terms of less post-operative pain and discomfort experienced by patients at the microsurgical site.
