Gingival recession is significantly more common among smokers, while cigarette smoking has been shown to negatively influence healing following periodontal therapeutic procedures as compared to non-smokers. The objective of this study was to evaluate the influence of cigarette smoking on the outcome of coronally positioned flap (CPF) in the treatment of Miller Class I gingival recession defects.
Ten current smokers (≥10 cigarettes daily for at least 5 years) and 10 non-smokers (never smokers), each with one 3 to 4-mm Miller Class I recession defect in an upper canine or bicuspid, were treated with CPF. At baseline and 6 months, clinical parameters, probing depth (PD), clinical attachment level (CAL), recession depth (RD), recession width (RW) and apico-coronal width of keratinized tissue (KT) were determined.
Intra-group analysis showed that CPF was able to reduce RD and improve CAL in both groups (P < 0.001). Intergroup analysis demonstrated that smokers presented greater residual RD at 6 months and lower percentage of root coverage (60.09% versus 76.05%; P < 0.05). No smokers obtained complete root coverage compared to 30% of non-smokers (P < 0.05).
Within the limits of present study, it can be concluded that cigarette smoking may present negative impact on root coverage outcome by CPF as compared to non-smokers and therefore represent one more challenge to periodontal plastic therapy.

牙龈退缩在吸烟者中明显更为常见，并且与不吸烟者相比，吸烟已被证明会对牙周治疗程序后的愈合产生负面影响。本研究的目的是评估吸烟对冠向复位瓣（CPF）治疗米勒I类牙龈退缩缺损效果的影响。
10名当前吸烟者（每天至少吸10支烟，至少持续5年）和10名不吸烟者（从不吸烟），每人在上颌尖牙或双尖牙处有一个3至4毫米的米勒I类退缩缺损，接受CPF治疗。在基线和6个月时，测定临床参数，包括探诊深度（PD）、临床附着水平（CAL）、退缩深度（RD）、退缩宽度（RW）和角化组织的冠根宽度（KT）。
组内分析表明，CPF能够在两组中均减少RD并改善CAL（P < 0.001）。组间分析表明，吸烟者在6个月时呈现出更大的残余RD，且牙根覆盖百分比更低（60.09%对76.05%；P < 0.05）。与30%的不吸烟者相比，没有吸烟者获得完全牙根覆盖（P < 0.05）。
在本研究的范围内，可以得出结论，与不吸烟者相比，吸烟可能对CPF的牙根覆盖结果产生负面影响，因此对牙周整形治疗来说是又一个挑战。关键词：牙龈退缩/治疗；瓣；吸烟/不良反应。如何引用本文：纳纳瓦蒂B，巴夫萨尔N V，马利J。用于牙根覆盖的冠向复位瓣：吸烟者与不吸烟者的比较。《国际口腔健康杂志》2013；5（2）：21 - 27。
