The periodontal tissues are continuously exposed to specific bacterial components that have the ability to alter many local functions. Normal endogenous infections in healthy mouths cause disease when their numbers increase significantly.
Determine the percentage of different periodontal pathogenic bacteria and their association with periodontal status.
Cross-sectional, analytical.
School children of both genders in Saudi Arabia.
Clinical examination consisted of measurement of the gingival and periodontal supporting tissue including attachment loss, probing pocket depth and furcation involvement following the National Health and Nutrition Examination Survey (NHANES) and taking samples of the subgingival bacterial flora.
The percentage of periodontal pathogenic bacteria and its association with periodontal status in Saudi Arabia.
Bacterial samples were collected from 277 subjects.
Aggregatibacter actinomycetemcomitans was present in 21.7% of the subjects, Porphyromonas gingivalis in 21.3%; Tannerella forsythia in 10.1%; Treponema denticola in 34.7% and Prevotella inter-media in 12.3%. The red complex bacteria were found in 2.9% of the subjects.
The percentages of bacteria varied but only T denticola was significantly associated with periodontal breakdown. In addition, the presence of more than 2 of the 5 species tested were significantly associated with tissue damage.
Cannot be generalized to all of Saudi Arabia. Larger controlled studies are needed.

牙周组织持续暴露于具有改变多种局部功能能力的特定细菌成分中。健康口腔中的正常内源性感染在其数量显著增加时会引发疾病。
确定不同牙周病原菌的百分比及其与牙周状况的关联。
横断面分析研究。
沙特阿拉伯的学龄儿童。
临床检查包括按照美国国家健康和营养检查调查（NHANES）的方法测量牙龈和牙周支持组织，包括附着丧失、探诊深度和根分叉病变，并采集龈下细菌菌群样本。
沙特阿拉伯牙周病原菌的百分比及其与牙周状况的关联。
从277名受试者中采集细菌样本。
伴放线聚集杆菌在21.7%的受试者中存在，牙龈卟啉单胞菌在21.3%的受试者中存在；福赛坦纳菌在10.1%的受试者中存在；具核梭杆菌在34.7%的受试者中存在，中间普氏菌在12.3%的受试者中存在。红色复合体细菌在2.9%的受试者中被发现。
细菌的百分比各不相同，但只有具核梭杆菌与牙周破坏显著相关。此外，所检测的5种细菌中，有超过2种存在与组织损伤显著相关。
不能推广至整个沙特阿拉伯。需要开展更大规模的对照研究。
无。
