The present radiographic and clinical survey was performed to study the prevalence of "incipient juvenile periodontitis" in a population of 16-year old adolescents in Switzerland. The subjects to be screened were selected on the basis of the population distribution in the year 1980 in the territory of Switzerland. 7% of all 16-year old adolescents proportionally distributed into the different ethnic groups of Switzerland were incorporated in the study. From the school dental systems, a total of 7604 pairs of bite-wing radiographs were obtained and evaluated for fillings and iatrogenic factors, gross amounts of calculus, resorption of alveolar bone. A diagnosis of "incipient juveline periodontitis" was given if the clinical criteria of this disorder proposed by Baer were met. In 7142 pairs of bite-wing radiographs, such a diagnosis was attributed to 7 female and 12 male patients. Subsequently, they were asked if they would be examined at the University of Berne School of Dental Medicine. On the basis of history, a complete periodontal chart and full mouth radiographs, the diagnosis was confirmed or refuted. 8 patients (4 female and 4 male) were definitely diagnosed as "incipient juvenile periodontitis". This resulted in a prevalence of 0.1% with a ratio of female to male of 1:1 in the country of Switzerland at age 16. As in other industrialized countries, this prevalence seems not to be a major public health problem.
本次影像学和临床调查旨在研究瑞士16岁青少年人群中“早期青少年牙周炎”的患病率。根据1980年瑞士境内的人口分布情况选择待筛查对象。按比例从瑞士不同种族群体中抽取了所有16岁青少年的7%纳入研究。从学校牙科系统共获取了7604对咬合翼片，并对其进行评估，内容包括充填物和医源性因素、牙结石总量、牙槽骨吸收情况。如果符合Baer提出的该疾病临床标准，则诊断为“早期青少年牙周炎”。在7142对咬合翼片中，有7名女性和12名男性患者被诊断为此病。随后，询问他们是否愿意在伯尔尼大学牙医学院接受检查。根据病史、完整的牙周检查表和全口X光片，确诊或排除该诊断。8名患者（4名女性和4名男性）被明确诊断为“早期青少年牙周炎”。这导致在瑞士16岁人群中患病率为0.1%，男女比例为1:1。与其他工业化国家一样，这种患病率似乎并非重大公共卫生问题。
