侵袭性牙周炎是影响全身健康个体的牙周疾病之一，通常年龄在30岁以下。该疾病的特点是骨质破坏迅速，与菌斑的数量不一致。这项横断面研究的目的是确定伊朗德黑兰高中 15 至 18 岁学生中侵袭性牙周炎的患病率。
研究设计
基于系统和整群随机抽样，共选择了 5,590 名学生。对门牙和第一磨牙的六个区域进行了牙袋深度探测。超过一颗牙齿上牙袋深度 > 或 = 4 毫米的学生被转介进行射线照相检查。如果牙间隔嵴与 CEJ 之间的距离 > 或 = 2 毫米，则进行全面的临床和放射学检查。
结果
只有七人，四名女孩和三名男孩，符合局部侵袭性牙周炎的诊断标准。一名患者被诊断患有广泛性侵袭性牙周炎。因此，本研究中15-18岁学龄儿童侵袭性牙周炎的患病率为0.13%。
结论
本研究表明，德黑兰侵袭性牙周炎的患病率较低，与其他国家相同年龄范围和诊断标准的研究相似。
OBJECTIVE
Aggressive periodontitis is one of the periodontal diseases that affects systemically healthy individuals usually under the age of 30 years. The disease is characterized by rapid bone destruction which is inconsistent with the amount of bacterial plaque. The purpose of this cross-sectional study is to determine the prevalence of aggressive periodontitis among students aged 15 to 18 years in high schools of Tehran, Iran.
RESEARCH DESIGN
Based on systematic and cluster random sampling, 5,590 students were selected. Probing pocket depth on six areas of incisors and first molars was carried out. Students with pocket depth > or = 4 mm on more than one tooth were referred for radiographic examination. In cases where the distance between the crest of interdental septa and CEJs were > or = 2 mm, full clinical and radiographic examination were performed.
RESULTS
Only seven persons, four girls and three boys, had the diagnostic criteria of localized aggressive periodontitis. One patient was diagnosed with generalized aggressive periodontitis. Therefore, the prevalence of aggressive periodontitis among 15-18 years old school- children was 0.13% in this study.
CONCLUSION
The present study indicates that the prevalence of aggressive periodontitis in Tehran is low and similar to the studies of the same age range and diagnostic criteria in other countries.
