According to previous findings, gingival bleeding seems to be reduced under the influence of cigarette smoking. The present study deals with the effect of non-surgical therapy on gingival bleeding in smokers and non-smokers. The underlying hypothesis was that the therapeutic effect in terms of reduction of gingival bleeding might differ in smokers and non-smokers. Twenty patients with moderate to severe periodontitis, 10 smokers and 10 non-smokers, took part in the study. Gingival bleeding was assessed by probing under a standardized pressure (60 g), and measurements were performed before and 1 month after the completion of active treatment. The active treatment included debridement of supra- and sub-gingival deposits by means of hand instrumentation. The treatment caused a reduction in plaque index and gingival bleeding both in smokers and in non-smokers. The plaque reduction was significantly greater in smokers. Nevertheless, the reduction in gingival bleeding was significantly less pronounced than that attained in non-smokers. The findings suggest that the gingival bleeding response to treatment is reduced in smokers. It would seem that in response to a given amount of plaque reduction the changes in gingival bleeding will be less apparent under the influence of smoking.
根据先前的研究结果，牙龈出血在吸烟的影响下似乎会减少。本研究探讨了非手术治疗对吸烟者和非吸烟者牙龈出血的影响。潜在的假设是，吸烟者和非吸烟者在减少牙龈出血方面的治疗效果可能不同。20名患有中度至重度牙周炎的患者（10名吸烟者和10名非吸烟者）参与了该研究。通过在标准化压力（60克）下进行探诊来评估牙龈出血情况，并在积极治疗开始前和结束后1个月进行测量。积极治疗包括通过手工器械清除龈上和龈下沉积物。治疗使吸烟者和非吸烟者的菌斑指数和牙龈出血均有所减少。吸烟者的菌斑减少更为显著。然而，吸烟者牙龈出血的减少明显不如非吸烟者明显。研究结果表明，吸烟者对治疗的牙龈出血反应有所降低。似乎在吸烟的影响下，对于给定程度的菌斑减少，牙龈出血的变化将不太明显。
