J Endod:伴随窦道牙齿的根管根尖系统和尖周组织的组织细菌学条件

2018-01-25 lishiting MedSci原创

组织细菌学研究描述的是有窦道及尖周脓肿牙齿的根内和根外感染模式。

组织细菌学研究描述的是有窦道及尖周脓肿牙齿的根内和根外感染模式。

研究从24颗根尖周炎以及伴随窦道的牙齿牙根(8颗未治疗和16颗已治疗)中提取的活检样本作为评估对象。样本通过根尖外科手术或拔除获取,并进行处理以备组织细菌学和组织病理学检验。

结果显示,所有样本的根管根尖系统均发现细菌存在,分别存在于主根管(22颗牙)及侧支根管(17颗牙)。4例病例未发现根外感染。在17颗牙齿(5颗未治疗和12颗已治疗)中,根外细菌的存在作为菌斑生物膜粘附于牙根外部的表面,2例损伤中检测出放线菌集落,2例损伤中发现浮游细胞。另外,10颗牙齿存在明显的根外结石(矿化生物膜)。

结论:伴随尖周脓肿和窦道的牙齿在根管根尖系统以及尖周损伤中表现出复杂的感染模式,并以菌斑生物膜为突出表现。
