The purpose of the present study was to evaluate the stability of soft tissue conditions in gingival recession defects treated with GTR. The study population was selected among those patients who had been treated with GTR procedures for Miller’s Class I or II, deep ( 3 mm), buccal gingival recession defects. Defects were included only when they had revealed recession depth reduction 2 mm and root coverage 60% at 6 months following GTR treatment. These defect were regarded as successfully treated and scheduled for further monitoring. 20 patients, 11 males and 9 females, aged 23 to 57 years (mean age: 33.2 years), each contributing one defect, were selected. 9 patients were smokers ( 10 cigarette per day). Recession depth (RD), probing depth (PD), clinical attachment level (CAL), and width of keratinized gingiva (KG) were assessed immediately before surgery (presurgery examination), at 6 months posturgery (baseline examination), and at 4 years postsurgery (4-year examination). At baseline examination, RD reduction was 3.6 0.9 mm (mean root coverage: 80%). CAL gain amounted to 4.2 1.3 mm, 60% of the defects showing CAL gain 4 mm. KG increased from 1.9 1.2 mm at presurgery examination to 3.1 0.9 mm at baseline examination. At 4-year examination, no significant changes from baseline RD, CAL and KG recordings were observed. Differences in baseline-4 year changes between smokers and non-smokers were not statistically significant. The results of the present study demonstrate that clinical outcome achieved following GTR procedure in gingival recession defects can be mantained over periods up to 4 years.

Abstract
The purpose of the present study was to evaluate the stability of soft tissue conditions in gingival recession defects treated with GTR. The study population was selected among those patients who had been treated with GTR procedures for Miller’s Class I or II, deep ( 3 mm), buccal gingival recession defects. Defects were included only when they had revealed recession depth reduction 2 mm and root coverage 60% at 6 months following GTR treatment. These defect were regarded as successfully treated and scheduled for further monitoring. 20 patients, 11 males and 9 females, aged 23 to 57 years (mean age: 33.2 years), each contributing one defect, were selected. 9 patients were smokers ( 10 cigarette per day). Recession depth (RD), probing depth (PD), clinical attachment level (CAL), and width of keratinized gingiva (KG) were assessed immediately before surgery (presurgery examination), at 6 months posturgery (baseline examination), and at 4 years postsurgery (4-year examination). At baseline examination, RD reduction was 3.6 0.9 mm (mean root coverage: 80%). CAL gain amounted to 4.2 1.3 mm, 60% of the defects showing CAL gain 4 mm. KG increased from 1.9 1.2 mm at presurgery examination to 3.1 0.9 mm at baseline examination. At 4-year examination, no significant changes from baseline RD, CAL and KG recordings were observed. Differences in baseline-4 year changes between smokers and non-smokers were not statistically significant. The results of the present study demonstrate that clinical outcome achieved following GTR procedure in gingival recession defects can be mantained over periods up to 4 years.
