Aim:
A mucogingival deficiency is considered a potential risk factor for periodontal disease. In particular, mucogingival deficiency can lead to gingival recession, which is a pathological entity per se, due to the increased risk for dental hypersensitivity and root caries. The aim of this study was to evaluate and compare 2 bilaminar grafting techniques normally employed to achieve root coverage.
Methods:
Thirty-five patients were divided into 2 groups. Group 1 included 19 patients with 49 gingival recessions treated by Nelson technique (as modified by Harris), while group 2 included 15 patients with 40 recessions treated by Langer technique. Clinical evaluation was performed at preoperative level (T0), after 1 month (T1) and after 1 year (T2). Statistical analysis was performed by means of Friedmann and Wilcoxon test and U-Mann-Whitney test.
Results:
The statistical analysis did not reveal any significant difference between groups, both in terms of percentage of root coverage and of width of keratinizaed gingiva gain. A significant difference was only observed within each group, for the amount of keratinized gingiva at T1 vs T0 and at T2 vs T1.
Conclusions:
This study did not show any statistical difference between the Nelson and the Langer technique as to root coverage and gain in keratinized gingiva.
