摘要
本实验就11名非腐败坏死型拔牙创干槽症与8名腐败坏死型干槽症患者的拔牙创口的细菌进行了分离鉴定。结果表明两种类型的干槽症均为口腔正常菌群的混合感染,但在与某些特殊细菌的关系上却有较明显的差异,特别是与口腔专性厌氧菌增加的关系较大。本文提示患区各种细菌的比例与正常菌群的比例差异越大,则病变越重。本文的结果也说明了一些破坏正常生理结构的外科手术最终都将导致微生态失调或菌群失调,引起手术部位的病变。
The alceolalgia of extraction wounds often was found after extrction in dentofacial surgery. This paper discussed about the relationship between normal oral flora and different types of alecolalgia of extraction wounds . H patients with non-putrescent type of alceolalgia (A group) , and S patients with putrescent type of alceolalgia ( B group) were examined.Samples were collected from the dental cavity and cul tured under aerobic and anaerobic conditions. Isolates were identified to genus and species. Results suggested that alceolalgia of extrac tion wound represented a kind of mixed bacterial infections by normal oral microbial flora. The predominant cultivable microflora from A group were aerobic and facultatively anaerobic bacteria.Gram (+) cocci were found with the highest incadence( 100% of Strepto- coccus,and 54.5% of S.epidermidis)in A group. However , the isolation rate of anaerobes was found higher in B group than A group. Fusobacterium were detected in 9.1% of A group, 50% of B group; Blackpigmented Bacteroides were not detected in A group, whereas it was found in 50% of B group.The microbes belong to Capuocytophaga was isolated from both groups.
