中文摘要 | 本研究係以直接暗視顯微鏡與厭養培養技術培養某些菌屬來探討牙周病患者病灶中之牙齦下菌叢。不同型牙周病包括牙齦炎、年輕型牙周炎、成人型牙周炎與正常人相比較。結果顯示正常人健康牙周位置比牙周病患者之病變位置具有較高比例的球菌屬與不動桿菌屬以及低比例的Bacteroides gingivals (Bg)或螺旋體(Spriochetes)。而Spirochetes是牙齦炎、年輕型牙周炎與成人型牙周炎患者牙齦下菌叢中之主要形態型別,平均約為20-40%。由細菌培養結果無法區別牙齦炎與成人型牙周炎。11位局部年輕型牙周炎患者中有三位無法分離出Actinobacillus actinomycetemocomitans (Aa),這些發現顯示Bg在牙齦炎與成人型牙周炎之牙齦下菌斑中為主要菌叢;Aa(<3%)與年輕型牙周炎有督,Spriochetes為牙齦炎、年輕型牙周炎與成人型牙周炎之主要形態形別,而動桿菌屬為牙齦炎與成人型牙周炎之主要形態型別。 |
英文摘要 | Subgingval microflora in diseased sites in patients with periodontal disease were examined by culture of certain bacterial species and direct dark-field microscopy. Patients with varying forms of periodontal disease including gingivitis, juvenile periodintitis and adult periodontitis were compared with normal subjects. Healthy periodontal sites in normal subjects were populated by significantly higher proportions of cooci and nonmotile rods, and lower proportions of Bacteroides gingivalis (Bg), or spirochetes as compared to the diseased sites in patients with gingivitis, juvenile periodontitis and adult perioontitis. The spirochetes were major morphotypes in the subgingival plaque of gingivitis, juvenile periodontitis and adult periodontitis. Three of elven localized juvenile periodontitis (LJP) patients were noted as not having detectable Actinobacillus actinomycetemcomitans (Aa). These findings suggest that certain bacterial species such as Bg appear to be predominat in the subgingival plaque of gingivitis and adult periodontitis, Aa (<3%) to be associated with juvenile periodontitis, spirochetes are major morphotypes in the subgingival plaque of gingivitis, juvenile periodontitis and adult per |
