这项研究的目的是评估根面龋病在德国波美拉尼亚成年人口中的患病率和分布。研究样本包括6,267名计划在1997年至2001年进行检查的随机受试者(基于人群的横断面研究，应答率：69%，年龄范围为20-79岁)。499名无牙颌者被排除在根据世界卫生组织指南(1997年)进行的牙科检查之外(12%)。在统计分析中，计算了不同年龄组的频率分布、平均值和中位数，并对其进行了细分。暴露和受影响的根面百分比随着年龄的增长而增加(根面龋齿指数4.6-10.6%)。龋齿/充填牙面的平均数量从人均0.4个(25-34岁)增加到2.3个(55-岁)，而老年人由于保留的牙齿数量较少而下降。填充物所占比例最大(69.5%)。龋齿/充填物多见于颊表面，以下颌前磨牙最高。在45岁以上的人中，大约有一半的人至少有一个龋齿/充填的牙根表面，老年人的残牙数量不断增加，根部龋病在波美拉尼亚和东德是一种相关的、可能正在增长的疾病。
The aim of this study was to assess the prevalence and distribution of root caries in the adult population of Pomerania, Germany. The study sample comprised 6,267 randomly selected subjects who were scheduled for examination from 1997 to 2001 (population-based cross-sectional study, response rate: 69%, age range 20–79 years). 499 edentulous persons were excluded from the dental examination (12%) performed according to WHO guidelines (1997). In the statistical analysis, frequency distributions, means and median values were calculated and subdivided for different age groups. The percentage of exposed and affected root surfaces increased with age (root caries index 4.6–10.6%). The mean number of carious/filled root surfaces (RDFS) rose from 0.4 per person (25–34 years) to 2.3 (55–64 years) and dropped for seniors due to the low number of retained teeth. Fillings comprised the largest proportion of the RDFS (69.5%). Most caries/fillings were found on buccal surfaces, the highest rate in mandibular premolars. With about half of over-45-year-olds having at least one carious/filled root surface and increasing number of retained teeth in seniors, root caries is a relevant and probably growing disease in Pomerania and East Germany.
