This register-based study assessed the frequency of and age-specified variation in tooth extractions in adults visiting private dentists in Finland in 2012-2017.
Retrospective study design was used on the register-based data of private sector services. Data of the entire 6 years, 2012-2017, included records of a total of 6,252,039 patients. From among these, further detailed information was gathered in 2012 for 1,058,305 patients, and in 2017, for 985,043 patients. For each 6 years, the data were aggregated into patients' 5-year age groups that were observation elements. Proportions of patients undergoing oral surgical treatments were compared during the 6 years 2012-2017, and details of tooth extractions in 2012 and 2017. Linear regression modelling was used to analyse thinkable age- and year-related inclinations in oral surgical treatments.
Across the 6 years, a total of 848,362 patients (13.6%) underwent oral surgical treatments, and the rates varied by year 13.3-13.8%. By age group, the smallest rates (9-10%) were for 35-49-year-olds and greatest (20-22%) for those aged below 25 or over 84. The rates in same-age groups were stable. In 2012 and 2017, mean numbers of tooth extractions per patient by year were 0.17 and 0.18, and per patients undergoing oral surgical treatments, 1.29 and 1.27, respectively. Proportion of patients undergoing oral surgical treatments and mean number of tooth extractions per patient was greater in younger and older age groups.
Tooth extractions in adults are age-dependent and age-specified differences remain stable across the years.
本基于登记的研究评估了 2012-2017 年间芬兰私人牙医就诊的成年人拔牙的频率和年龄变化。
使用基于登记的服务数据进行回顾性研究设计。2012-2017 年的六年期间共包括 6252039 名患者的数据。在此基础上，进一步对 2012 年的 1058305 名患者和 2017 年的 985043 名患者进行了详细信息的收集。每六年，数据被汇总为患者的 5 岁年龄组，作为观察要素。比较了 2012-2017 年 6 年间口腔手术治疗患者的比例，并比较了 2012 年和 2017 年拔牙的详细情况。使用线性回归模型分析口腔手术治疗中可能存在的年龄和年度相关趋势。
6 年间共有 848362 名患者（13.6%）接受了口腔手术治疗，治疗率在每年 13.3%-13.8%之间变化。按年龄组划分，35-49 岁年龄组的比例最小（9-10%），25 岁以下或 84 岁以上年龄组的比例最大（20-22%）。同年龄组的比例稳定。2012 年和 2017 年，每名患者每年拔牙的平均数量分别为 0.17 和 0.18，每名接受口腔手术治疗的患者分别为 1.29 和 1.27。接受口腔手术治疗的患者比例和每名患者拔牙的平均数量在年轻和老年患者中更大。
成年人拔牙与年龄有关，年龄差异在多年间保持稳定。
