Periodontal disease progression was studied on bitewing radiographs taken at baseline and after 1 year for a group of 422 teenagers who had no access to preventive or therapeutic dental services. Subjects exhibiting one or more proximal surfaces of 1st molars with longitudinal bone loss and/or with vertical bone defects at the 2nd examination were regarded as periodontal risk patients. This group then underwent a further examination in which periapical radiographs of the anterior teeth were taken and the clinical loss of attachment at the proximal surfaces of all teeth was assessed. Subsequently, the radiographic and clinical states of the risk group were compared. Most sites exhibiting bone loss during the study period displayed vertical bone defects and were largely confined to mesial surfaces of first molars. 24% of sites showing alveolar bone loss at baseline demonstrated further loss 1 year later. Girls exhibited significantly higher prevalence and incidence of sites showing bone loss than did boys. 24 children (5.7%) were regarded as periodontal risk patients. The radiographs significantly underestimated the prevalence of periodontal destruction in the risk group as compared to clinical measurements. It was concluded that using 2 bitewing radiographs is adequate for the identification of risk subjects, and that periodontal progression in adolescence occurs mainly in the first molar region and may affect girls more often than boys.
对一组422名无法获得预防性或治疗性牙科服务的青少年，在基线时和1年后拍摄的咬合翼片上研究牙周疾病进展情况。在第二次检查时，第一恒磨牙一个或多个邻面出现纵向骨质丧失和/或垂直骨缺损的受试者被视为牙周风险患者。然后该组接受进一步检查，拍摄前牙的根尖片，并评估所有牙齿邻面的临床附着丧失情况。随后，对风险组的影像学和临床状况进行比较。在研究期间，大多数出现骨质丧失的部位表现为垂直骨缺损，且主要局限于第一恒磨牙的近中面。在基线时显示牙槽骨丧失的部位中，24%在1年后出现了进一步的丧失。女孩出现骨质丧失部位的患病率和发病率显著高于男孩。24名儿童（5.7%）被视为牙周风险患者。与临床测量相比，X线片显著低估了风险组中牙周破坏的患病率。研究得出结论，使用两张咬合翼片足以识别风险受试者，并且青少年牙周疾病进展主要发生在第一磨牙区域，且对女孩的影响可能比男孩更频繁。
