BACKGROUND: Although subepithelial connective tissue graft (CTG) has been reported to be a predictable procedure for root coverage, the impact of smoking on the long-term outcome of periodontal plastic surgery is unclear. Hence, the aim of this study was to evaluate the effect of smoking, on a long-term basis, on the stability of gingival tissue following CTG treatment of gingival recession. METHODS: Twenty-two defects were treated by CTG in canine and premolar Miller Class I and II gingival recessions (11 smokers and 11 non-smokers). The following clinical measurements were obtained at baseline and at 1, 2, 3, 4, 6, 12, 18, and 24 months after surgery: plaque and gingival indexes, extension of gingival recession (GR), probing depth (PD), clinical attachment level (CAL), and gingival thickness. Individuals smoking > or =20 cigarettes/day for > or =5 years were considered smokers. RESULTS: Data analysis demonstrated that both groups presented similar plaque and gingival indexes (P >0.05), and an intragroup analysis showed that CTG was able to promote root coverage and increase gingival thickness in both groups over time (P <0.05). However, at 24 months postoperatively, statistical analysis showed that smokers presented poorer outcomes with regard to PD, GR, and CAL (P <0.05); in addition, a more satisfactory stabilization of the gingival tissue was found in the non-smoker group. CONCLUSION: Smoking may represent a challenge to root coverage outcome for CTG because smoking significantly affected the stability of gingival tissue over time.
