Abstract

Abstract Introduction Periodontitis is a disease of the tissues surrounding the tooth, leading to tooth loss. Missing teeth are often restored with fixed prostheses supported by implants. The aim of this study was to analyze subgingival microbiota in periodontal pockets and around implants, as well as to assess the correlation of periodontal parameters and risk factors for periodontitis with the presence of selected bacteria. Materials and Methods The study included 33 patients of both sexes, aged 39 to 79 years, having their own dentition and intraosseous implants with healthy periodontium or reversible gingivitis. The patients underwent periodontal examination and bacteriological analysis with the use of a PET RT-PCR kit (MIP Pharma, Germany). Results Less plaque was observed on implant surfaces than around natural teeth (28.7% vs. 39.8%). On the other hand, significantly deeper pockets (2.9 vs. 2.3 mm), and a slightly higher gingival bleeding index (27.9 vs. 22.6%) were noted around implants. Conclusions There were no significant differences in the overall presence and number of studied pathogens between the natural teeth and implants. In the case of natural teeth, the presence of Porphyromonas gingivalis , Treponema denticola , Tannerella forsythia and Prevotella intermedia showed correlation with clinical status: the amount of plaque (Td, Tf), bleeding (Td, Tf, Pi) and probing depth (Pg, Td, Tf, Pi). Such relationships were not observed in the case of implants. Bacteria from periodontal pockets also demonstrated more correlation with the general condition compared to bacteria residing in tissues around implants.

种植体和天然牙齿周围的牙周组织状况和选定的微生物
牙周炎是一种牙齿周围组织的疾病,可导致牙齿脱落。缺失的牙齿通常用种植体支撑的固定假体修复。本研究的目的是分析牙周袋和种植体周围的牙龈下微生物群,并评估牙周参数和牙周炎危险因素与选定细菌存在的相关性。材料与方法本研究纳入33例患者,男女,年龄39 ~ 79岁,有自己的牙列和骨内种植体,牙周组织健康或可逆性牙龈炎。使用PET RT-PCR试剂盒(德国MIP制药公司)对患者进行牙周检查和细菌学分析。结果种植体表面菌斑明显少于天然牙(28.7% vs. 39.8%)。另一方面,种植体周围的口袋明显更深(2.9 vs 2.3 mm),牙龈出血指数略高(27.9 vs 22.6%)。结论天然牙与种植牙的病原菌总体存在和数量无显著差异。在天然牙中,牙龈卟啉单胞菌、牙密螺旋体、连珠Tannerella forsythia和Prevotella intermedia的存在与临床状况相关:菌斑数量(Td, Tf)、出血(Td, Tf, Pi)和探探深度(Pg, Td, Tf, Pi)。在植入物的情况下没有观察到这种关系。与居住在种植体周围组织中的细菌相比,来自牙周袋的细菌也显示出与一般情况的更多相关性。
