Abstract

Aim To evaluate regional disparities in the prevalence, severity and extent of probing depths (PDs) as well as tooth loss in German adults aged 19–74, using data from the baseline study of the German National Cohort (NAKO; 2014–2019). Methods Dental examinations were recorded at two levels: Level 1 (18/18 centres; N = 184,871; tooth counts including third molars and dental interview) and Level 2 (8/18 centres, not geographically representative; N = 18,389; recording of PDs). We evaluated differences by sex, age and study region. All data were survey‐weighted. For individuals aged 65–74, we supplemented tooth loss data from the Fifth German Oral Health Study and the Study of Health in Pomerania. Results Among Level 1 participants, the prevalence of edentulism was 1.7% (95% confidence interval: 1.6–1.9). The average mean PD was 1.89 mm (1.87–1.91). Both edentulism and PDs increased with increasing age. There were clear regional disparities, with the lowest prevalence of both in Augsburg/Regensburg in the south (1.3% and 1.64 mm) and the highest in Neubrandenburg in the north‐east (2.3% and 2.31 mm). Conclusion Clear regional disparities emerged. In light of demographic changes, these results highlight the importance of incorporating region‐specific oral health burdens into future healthcare planning and treatment concepts.

德国探牙深度和牙齿脱落患病率的地区差异——来自德国国家队列（NAKO）的结果

目的利用德国国家队列（NAKO; 2014-2019）基线研究的数据，评估德国19-74岁成年人探牙深度（pd）和牙齿脱落的患病率、严重程度和程度的地区差异。方法口腔检查分为两个级别：1级（18/18个中心，N = 184,871，牙齿计数包括第三磨牙和牙科访谈）和2级（8/18个中心，不具有地理代表性，N = 18,389，记录pd）。我们评估了性别、年龄和研究区域的差异。所有数据均采用调查加权。对于65-74岁的个体，我们补充了来自第五次德国口腔健康研究和波美拉尼亚健康研究的牙齿脱落数据。结果在1级参与者中，蛀牙的患病率为1.7%（95%可信区间：1.6-1.9）。平均PD为1.89 mm（1.87 ~ 1.91）。随着年龄的增长，牙齿数量和pd都在增加。存在明显的地区差异，南部的奥格斯堡/雷根斯堡的患病率最低（1.3%和1.64毫米），东北部的新勃兰登堡的患病率最高（2.3%和2.31毫米）。结论区域差异明显。鉴于人口结构的变化，这些结果强调了将特定地区的口腔健康负担纳入未来医疗保健计划和治疗概念的重要性。

期刊介绍： Journal of Clinical Periodontology was founded by the British, Dutch, French, German, Scandinavian, and Swiss Societies of Periodontology. The aim of the Journal of Clinical Periodontology is to provide the platform for exchange of scientific and clinical progress in the field of Periodontology and allied disciplines, and to do so at the highest possible level. The Journal also aims to facilitate the application of new scientific knowledge to the daily practice of the concerned disciplines and addresses both practicing clinicians and academics. The Journal is the official publication of the European Federation of Periodontology but wishes to retain its international scope. The Journal publishes original contributions of high scientific merit in the fields of periodontology and implant dentistry. Its scope encompasses the physiology and pathology of the periodontium, the tissue integration of dental implants, the biology and the modulation of periodontal and alveolar bone healing and regeneration, diagnosis, epidemiology, prevention and therapy of periodontal disease, the clinical aspects of tooth replacement with dental implants, and the comprehensive rehabilitation of the periodontal patient. Review articles by experts on new developments in basic and applied periodontal science and associated dental disciplines, advances in periodontal or implant techniques and procedures, and case reports which illustrate important new information are also welcome.
