The objective of the present investigation was to study the influence of cigarette smoking on the occurrence of gingival bleeding. The occurrence of bleeding was evaluated by probing at a standardized pressure of 60 g. The bleeding occurrence of each patient was indicated by the number of sites bleeding on probing as a percentage of the total. Twenty patients with moderate to severe periodontitis, 10 smokers and 10 non-smokers, participated in the study. The smoker patients had been regular smokers for at least 15 years, their present tobacco consumption being 20 cigarettes a day or more. The results showed that, although they had a significantly greater plaque index, smokers displayed a significantly lower bleeding occurrence than non-smokers, the average being 27% and 40%, respectively. The present findings suggest that gingival bleeding as measured by probing with a pressure of 60 g is reduced in smokers with periodontitis.
本研究的目的是探讨吸烟对牙龈出血发生情况的影响。通过在60克标准化压力下进行探诊来评估出血的发生情况。每位患者的出血发生情况用探诊时出血部位的数量占总数的百分比来表示。20名中重度牙周炎患者参与了这项研究，其中10名吸烟者和10名不吸烟者。吸烟患者至少有15年的规律吸烟史，目前每天吸烟20支或更多。结果显示，尽管吸烟者的菌斑指数显著更高，但他们的出血发生率显著低于不吸烟者，平均分别为27%和40%。目前的研究结果表明，在患有牙周炎的吸烟者中，用60克压力探诊测量的牙龈出血情况有所减少。
