摘要

前言:本研究的目的是测定慢性牙周炎吸烟者和非吸烟者在刮治和牙根平整前后血清和唾液中的一氧化氮(NO)水平,并比较一氧化氮水平与牙周炎严重程度的关系。材料与方法:60人参加了这项研究,分为三组。对照组(第一组)包括20例牙周组织健康的非吸烟者。另外两组各有20名患者,其中第二组是患有慢性牙周炎的非吸烟者,第三组是患有慢性牙周炎的吸烟者。此外,本研究使用Griess反应间接量化NO的生成,以测定血清和唾液中的亚硝酸盐水平。结果:III组大鼠唾液及血清NO均值均高于II组,且NO明显降低(P <治疗后II组和III组与治疗前比较,差异均为0.01)。结论:血清和唾液NO水平可作为吸烟者牙周炎症状况的良好预测指标。

Levels of nitric oxide in smokers and nonsmokers with chronic periodontitis before and after nonsurgical periodontal treatment
Introduction: The purpose of this study was to determine the level of nitric oxide (NO) in both serum and saliva of smokers and nonsmokers with chronic periodontitis before and after scaling and root planing, as well as to compare the same (NO levels) with the severity of periodontitis. Materials and Methods: Sixty people took part in the study and were divided into three groups. The control group (Group I) involved 20 patients who were nonsmokers with healthy periodontium. The other two groups included 20 patients each, where Group II was nonsmokers with chronic periodontitis and Group III was smokers with chronic periodontitis. In addition, NO generation was quantified indirectly in this study using the Griess reaction to determine the nitrite level in serum and saliva. Results: The mean value of salivary and serum NO was higher in Group III than in Group II, and NO decreased considerably ( P < 0.01) in both Groups II and III after treatment compared to before treatment. Conclusion: Serum and salivary NO levels can be used as a good predictor of the inflammatory condition of the periodontium in smokers.
