| 摘 要： | 本文对14例慢性根尖周炎患者16个感染根管细菌培养检查的结果发现:以厌氧菌为优势的混合菌感染是慢性根尖周炎感染根管细菌学的主要特点。穿髓根管由于敞开的髓腔,同一根管内4—9种细菌混合感染者占87.5％;未穿髓的感染根管2—3种细菌混合感染的占62.5％,4种以上细菌混合感染的占37.5％。优势的感染菌包括产黑色素类杆菌、口腔类杆菌、口类杆菌、具核梭杆菌、干酪乳杆菌、内氏放线菌等6种厌氧菌;血液链球菌、变链球菌和酿脓链球菌为最常见的兼性厌氧菌。本文指出口腔正常菌群是感染根管的机会病原菌。

| Abstract: | 16 infected root canal from 14 persons with chronic periapical periodontitis were study using two no-selective and four Selective media. The results indicated that anaerobe were found significantly higher proportions in these infected root canal with mixed bacterial isolates. There were higher incidence of the samples with 4-9 spec ies in exposed pupl chember groups (87.5%) than in unexposed pupl chember groups (37.596). The prodominant cultivable anaerobic isolates incude: B. melaninogenicus, B.oralis, B.oriis, F.nuclea- tum, L.casei and A. neaslundii. More commonly facultative anaerobic isolationswere S.sanguis. S.mutans. and S. pyogenes. The paper suggested that normal oral flora arc potential Pathogens in chronic periapical periodontitis. |
