The purpose of the present parallel-design, controlled clinical trial was to evaluate the treatment outcome following flap debridement surgery (FDS) procedures in smokers compared to non-smokers. 58 systemically healthy subjects with moderate to advanced periodontitis, who presented one area (3 to 6 teeth) with persisting diseased sites after initial therapy, were selected. 29 patients (mean age: 39.7 years, 20 males) were smokers, while 29 patients (mean age: 43.9 years, 7 males) were non-smokers. Full-mouth plaque (PlI) and Bleeding on Probing (BoP) scores, probing depth (PD) and clinical attachment level (CAL) were assessed immediately before surgery and at 6 months postsurgery. PlI and BoP scores significantly decreased in both smokers and non-smokers. PD reduction and CAL gain were greater in non-smokers (2.4 0.9 mm and 1.6 0.7 mm, respectively) than in smokers (2.0 0.9 mm and 1.2 0.8 mm, respectively), however these differences did not reach the statistical significance. When sites presenting baseline PD 7 mm were considered, smokers showed significantly less PD reduction (3.1 1.1 mm) and CAL gain (1.9 1.2 mm) compared to non-smokers (3.9 0.8 mm and 2.8 1.0 mm, respectively). In smokers, there was a significant difference in mean CAL change in patients with exposure >15 packs/years (0.9 0.5 mm) compared to those with lower exposure (1.5 0.8 mm). The results of this study suggest that healing outcome following FDS procedures is impaired in cigarette smokers. This study was partly supported by MURST grant #97/60/06/014.

Abstract
The purpose of the present parallel-design, controlled clinical trial was to evaluate the treatment outcome following flap debridement surgery (FDS) procedures in smokers compared to non-smokers. 58 systemically healthy subjects with moderate to advanced periodontitis, who presented one area (3 to 6 teeth) with persisting diseased sites after initial therapy, were selected. 29 patients (mean age: 39.7 years, 20 males) were smokers, while 29 patients (mean age: 43.9 years, 7 males) were non-smokers. Full-mouth plaque (PlI) and Bleeding on Probing (BoP) scores, probing depth (PD) and clinical attachment level (CAL) were assessed immediately before surgery and at 6 months postsurgery. PlI and BoP scores significantly decreased in both smokers and non-smokers. PD reduction and CAL gain were greater in non-smokers (2.4 0.9 mm and 1.6 0.7 mm, respectively) than in smokers (2.0 0.9 mm and 1.2 0.8 mm, respectively), however these differences did not reach the statistical significance. When sites presenting baseline PD 7 mm were considered, smokers showed significantly less PD reduction (3.1 1.1 mm) and CAL gain (1.9 1.2 mm) compared to non-smokers (3.9 0.8 mm and 2.8 1.0 mm, respectively). In smokers, there was a significant difference in mean CAL change in patients with exposure >15 packs/years (0.9 0.5 mm) compared to those with lower exposure (1.5 0.8 mm). The results of this study suggest that healing outcome following FDS procedures is impaired in cigarette smokers.
