未经证实:牙周炎是牙周设备的炎症,导致结缔组织附着和牙齿脱落的破坏。红色复合细菌可能导致疾病开始。牙周炎中的细菌感染导致远处器官的低度慢性感染和炎症。值得注意的是,衰老会影响免疫反应。
UNASSIGNED:本研究的目的是分析衰老对口腔卫生和炎症状况的影响。此外,评价龈下菌斑口腔卫生状况与红色复合细菌载量的相关性。
未经评估:在这项横断面研究中,我们检查了20名成人和20名老年牙周炎患者。记录临床参数包括口腔卫生学简化指数(OHI-S)和乳头状出血指数(PBI)。从探测深度为5-7mm的牙齿收集龈下菌斑,并用逆转录聚合酶链反应(RT-PCR)分析红色复合细菌定量。进行统计分析,分别。
未经评估:两组的口腔卫生状况都很差,高OHI-S和PBI反映。红色复合细菌的数量(P.牙龈,T.Denticola,与成年组相比,老年组的连翘T.forsythia)明显更高。OHI-S与红色复合菌呈显著的强线性关系(r<1,p<0.05)。只有牙龈卟啉单胞菌与PBI值有很强的线性关系,具有统计学意义。(r<1,p<0.05)。牙龈卟啉单胞菌载量显著高于凹凸棒菌和连翘菌载量,它与成人和老年人组的口腔卫生不良以及老年人组的PBI相关。
未经评估:衰老会影响红色复杂细菌负荷和口腔卫生状况,但不是炎症。这些发现有助于开发针对老年人牙周炎细菌方面的新型治疗策略。
UNASSIGNED: Periodontitis is an inflammation of the periodontal apparatus leads to destruction of connective tissue attachment and tooth loss. Red complex bacteria may contribute to disease initiation. Bacterial infection in periodontitis leads to a low-grade chronic infection and inflammation in distant organs. Notably, aging can affect the immune response.
UNASSIGNED: The aim of this study was to analyze the effect of aging on oral hygiene and inflammation condition. Moreover, to evaluate the correlation between the oral hygiene condition and red complex bacterial load in subgingival plaque.
UNASSIGNED: In this cross-sectional study, we examined 20 adult and 20 elderly subjects with periodontitis. Clinical parameters included Oral Hygiene Index Simplified (OHI-S) and Papillary Bleeding Index (PBI) were recorded. Subgingival plaque was collected from the tooth with a probing depth of 5-7 mm and analyzed with a reverse transcription polymerase chain reaction (RT-PCR) for red complex bacteria quantification. Statistical analysis was performed, respectively.
UNASSIGNED: Both groups had poor oral hygiene conditions, reflected by high OHI-S and PBI. The quantity of red complex bacteria (P. gingivalis, T. denticola, T. forsythia) in the elderly group was significantly higher in comparison to the adult group. There was significant strong linear relationship between OHI-S and red complex bacteria (r < 1, p < 0.05). Only P. gingivalis bacteria with PBI values had a strong linear relationship and statistically significant. (r < 1, p < 0.05). P. gingivalis load was significantly higher than T. denticola and T. forsythia load, and it correlated with poor oral hygiene in the adult and elderly groups and with PBI in the elderly group.
UNASSIGNED: Aging affects to the red complex bacterial load and oral hygiene condition, but not the inflammation. These findings contribute to the development of novel treatment strategies focusing on bacterial aspect for periodontitis in the elderly.
