我们研究了一组牙周破坏高发的巴西青少年的牙周病进展和某些形式的破坏性牙周炎之间的关系，并通过限制第一磨牙的疾病测量和通过汇总和汇总部位评分到受试者水平评分来评估减少数据的充分性。在3年的时间里，每年对222名青少年进行咬翼x线检查。在第一磨牙附近出现大于或等于2个弧形骨病变的个体被诊断为青少年牙周炎（JP）患者，而在第一磨牙附近出现大于或等于1个垂直病变的个体被视为牙周风险受试者。大于或等于2颗第一磨牙出现纵向骨质流失的青少年被定义为高危患者。在13岁和16岁时，有JP 3名（1.3%）和4名（1.8%），有牙周危险的有12名（5.4%）和28名（12.6%）；高危组8例（3.6%）；4名（1.8%）13岁儿童第一磨牙缺失大于或等于1颗；因此，在3年的时间里没有发生后牙的脱落。对部位水平的数据分析显示，高危组的牙槽骨高度逐渐丢失，且波动不大，近端骨丢失比远端骨丢失更为明显。更简单的数据集是通过汇总一些站点分数或将这些分数汇集成学科水平的分数来构建的。这一程序有助于识别高风险受试者，并在受试者水平上研究疾病随时间的活动。结果表明，早期牙周炎和JP是密切相关但可区分的青少年牙周病形式，并强调早期识别有发展破坏性牙周病风险的受试者的重要性。青少年的疾病进展模式似乎与成人报告的相似。研究结果还表明，所采用的数据缩减方法在青少年牙周病进展的流行病学研究中是有用的。
WE STUDIED THE PERIODONTAL DISEASE PROGRESSION and the relationship between some forms of destructive periodonitis in a group of Brazilian adolescents with high prevalence of periodontal destruction, and evaluated the adequacy of reducing data by limiting the measurement of disease to first molars and by aggregating and pooling site-scores into subject-level scores. Over a period of 3 years 222 adolescents were examined annually by bite-wing radiographs. Individuals displaying arc-shaped bone lesions adjacent to greater-than-or-equal-to 2 first molars were diagnosed as juvenile periodontitis (JP) patients, while those with greater-than-or-equal-to 1 first molars showing vertical lesions were regarded as periodontal risk subjects. Teenagers with greater-than-or-equal-to 2 first molars exhibiting longitudinal bone loss were defined as high-risk patients. At the ages of 13 and 16 years, 3 (1.3%) and 4 (1.8%) subjects had JP, while 12 (5.4%) and 28 (12.6%) were regarded as periodontal risks; 8 (3.6%) subjects were assigned to the high-risk group; 4 (1.8%) 13-year olds had greater-than-or-equal-to 1 first molars missing; hence, no loss of posterior teeth occurred over a period of 3 years. Analyzing the data at the site-level revealed progressive loss and little fluctuation in the alveolar bone height in the high-risk group, and a more pronounced bone loss at the mesial than at the distal surfaces. Simpler data sets were constructed by aggregating some of the site-scores or by pooling these into subject-level scores. This procedure facilitated the identification of high-risk subjects and studying the disease activity over time at the subject level. The results indicate that early periodontitis and JP are closely related but distinguishable forms of periodontal disease in adolescents, and stress the importance of early identification of subjects at risk of developing destructive periodontal diseases. The pattern of disease progression in adolescents appears to resemble that reported in adults. The findings also suggest that the employed methods of data reduction are useful in epidemiological studies on periodontal disease progression in adolescents.
