RESUMO

The aim of this research was to evaluate the influence of tobacco smoking on the levels of FGG shrinkage and on the repair of the graft donor area. Ten smokers and twelve non-smokers patients, with <1mm of attached gingiva associated with oral hygiene deficiency, high frenulum attachment or gingival recession were selected to receive FGG for keratinize tissue augmentation. The clinical parameters of probing depth (PD), gingival margin level (GML), clinical attachment level (CAL), keratinized tissue (KT), gingival thickness (Tkn), and FGG high, length, and area were evaluated. The palate donor area was evaluated by immediate bleeding (IB) and complete wound epithelialisation (CE). The parameters were evaluated before surgery, 7, 15, 30, 60, and 90 days postsurgery. The outcomes of the present study show that, instead of the absence of statistically significant difference between smokers and non-smokers, there is a tendency for a negative impact of tobacco smoking. At 3 months postsurgery, the percentage of shrinkage of FGG area, high, and length in smokers (58%, 44%, and 25%, respectively) was greater than in non-smokers (44%, 31%, and 22%, respectively), but there was no statistic difference. The final amount of KT increased in both groups, however, was slightly smaller in smokers (4.91mm) than in non-smokers (5.49mm). A smaller percentage of smoker patients presented immediate bleeding than non-smoker patients (30% and 75%, respectively), the same occurred with complete wound epithelialisation (20% and 91.67%, respectively) at 15 days postsurgery. Within the limits of the present study, it can be concluded that FGG is an adequate technique for keratinized tissue augmentation in both, smokers and non-smokers. Cigarette smoking interferes with palate epithelialisation and bleeding, however, it does not have a negative impact on the clinical outcomes of FGG shrinkage
