AIM To evaluate age-specific aspects and changes in volume and content of endodontic treatment for adults visiting private dentists in Finland in 2012 and 2017. METHODOLOGY This study utilized register-based data of private dental care. The observation unit of the aggregated macro-level data was age group, with 5-year age groups from 20 to 24 years onwards and the oldest group combining all patients aged 90 years and over. Data from years 2012 and 2017 included all the oral health care of 2.04 million patients receiving reimbursement for treatment by private dentists; a total of 183 932 patients received at least one endodontic treatment and were analysed. The number of teeth receiving endodontic treatment was counted separately as pulp cappings, pulpotomies and root canal fillings according to number of canals filled per tooth. Statistical associations were assessed as correlation coefficients. RESULTS The mean age of endodontic patients was 53.6 years in 2012 and 55.9 years in 2017. In both years, 38% were aged from 50 to 64 years. In 2012, 9.9%, and in 2017, 8.0% of patients received at least one endodontic treatment; the older the patients, the fewer received endodontic treatment (r = -0.9). From 2012 to 2017, numbers of all patients and treatments decreased, endodontic patients and treatments even more notably, and in all age groups. Per thousand patients in 2017, 62.1 teeth received root canal treatment and 14.9 pulp capping. Pulp capping comprised 19.2%, pulpotomies 0.8% and root canal fillings 80.0% of teeth receiving endodontic treatment. Of root filled teeth, 45.1% received filling in one canal, 17.0% in two and 37.9% in three or more canals, multi-canal options being less frequent in older patients (r = -0.94). CONCLUSIONS Endodontic treatment, received by 9% of adult patients visiting private dentists in Finland, was strongly age-dependent, showing a decreasing trend with age and time.

芬兰私人牙医在2012年和2017年针对牙髓治疗的特定年龄发现：基于全国登记的观察。

目的评估2012年和2017年芬兰来访私人牙医的成年人的年龄特征，以及其根管治疗的数量和内容的变化。方法学本研究使用了基于登记的私人牙齿保健数据。汇总的宏观水平数据的观察单位是年龄组，年龄从20岁到24岁的5岁年龄组，而年龄最大的组则是所有90岁以上的患者。2012年和2017年的数据包括接受私人牙医治疗的204万患者的所有口腔保健; 共有183932例患者接受了至少一种牙髓治疗并进行了分析。根据每颗牙齿的根管充填数量，将接受牙髓治疗的牙齿数量分别计为牙髓盖，切髓术和根管充填。统计关联被评估为相关系数。结果牙髓患者的平均年龄在2012年为53.6岁，在2017年为55.9岁。在这两年中，有38％的年龄在50岁至64岁之间。2012年为9.9％，2017年为8.0％的患者接受了至少一种牙髓治疗; 患者年龄越大，接受牙髓治疗的次数就越少（r = -0.9）。从2012年到2017年，所有年龄段的所有患者和治疗的数量均下降，牙髓患者和治疗的比例更加显着。2017年，每千名患者中有62.1颗牙齿接受了根管治疗并加盖了14.9颗牙髓。接受牙髓治疗的牙髓压盖占19.2％，切牙术占0.8％，根管充填占80.0％。在根管充填的牙齿中，有45.1％的人填入了一条运河，其中17.0％的人填入了两条运河，而37.9％的人则填入了三个或更多的运河，在老年患者中多管选择较少（r = -0.94）。结论芬兰9％的就诊私人牙医的成年患者接受了牙髓治疗，该治疗强烈依赖年龄，并且随着年龄和时间的增长呈下降趋势。
