吸烟是牙周病发展过程中的一个潜在危险因素,以往的研究认为吸烟与牙槽骨的吸收有关,吸烟患者牙周附着丧失比例较高,且在年轻时即可发生严重的疾病。本研究的目的即比较吸烟和不吸烟的早发性牙周炎患者其临床及龈下微生物的变化特点。 材料和方法 选取60例早发性牙周炎患者,其中男性40例,年龄24～35岁;女性20例,年龄22～35岁,吸烟和不吸烟者各30例。临床检查包括探诊深度,附着丧失,菌斑指数,牙龈指数;并观察每个牙6个部位的牙龈探诊出血及脓性分泌物情况,另从每个患者两
Smoking is a potential risk factor for the development of periodontal disease. Previous studies suggested that smoking is related to alveolar bone absorption. Smoking patients have a high rate of loss of periodontal attachment and can develop serious diseases when they are young. The purpose of this study was to compare the clinical and subgingival microbial characteristics of smokers and nonsmokers with early-onset periodontitis. MATERIALS AND METHODS: Sixty patients with early-onset periodontitis were selected, including 40 males, aged 24-35 years and 20 females, aged 22-35 years and 30 smokers and non-smokers. The clinical examination included probing depth, loss of attachment, plaque index, gingival index; and gingival bleeding and purulent secretion observed at each of the six sites of each tooth, and the other two
