刘海霞

【摘要】目的:探讨产黑色素类杆菌(BPB)与慢性根尖周炎临床症状的相关性.方法:

采用PCR技术检测30个慢性根尖周炎患牙感染根管内5种BPB的定植情况,单因

素分析5种BPB与慢性根尖周炎临床症状的相关性.结果:牙龈卟啉单胞菌(Pg)、

牙髓卟啉单胞菌(Pe)与慢性根尖周炎的疼痛、肿胀呈正相关(OR2,P0.05),与

叩痛、窦道无相关性;变黑普氏菌(Pn)与慢性根尖周炎的叩痛、肿胀呈正相关

(OR2,P0.05),与疼痛、窦道无相关性;中间普氏菌(Pi)和产黑普氏菌(Pm)与慢性

根尖周炎的疼痛、叩痛、窦道和肿胀均无相关性.结论:Pg、Pe与慢性根尖周炎的

疼痛和肿胀密切相关,Pn与叩痛和肿胀密切相关.尚未发现Pi和Pm与慢性根尖周

炎临床症状的相关性.%AIM:Tostudythecorrelationbetweenblack-
