This study aimed to identify the factors influencing the changes in the number of teeth present and the number of healthy or filled surfaces between two time points.
Repeated cross-sectional data from population-based studies, namely the German Oral Health Studies (DMS-III vs. DMS-V), the Studies of Health in Pomerania (SHIP-START-0 vs. SHIP-TREND-0), and the Jönköping study (2003 vs. 2013), were analysed. Oaxaca decomposition models were constructed for the outcomes (number of teeth, number of healthy surfaces, and number of filled surfaces).
The number of teeth increased between examinations (DMS: +2.26 [adults], +4.92 [seniors], SHIP: +1.67, Jönköping: +0.96). Improvements in education and dental awareness brought a positive change in all outcomes. An increase in powered toothbrushing and inter-dental cleaning had a great impact in DMS (adults: +0.25 tooth, +0.78 healthy surface, +0.38 filled surface; seniors: +1.19 teeth, 5.79 healthy surfaces, +0.48 filled surface). Inter-dental cleaning decreased by 4% between SHIP-START-0 and SHIP-TREND-0, which negatively affected the outcomes.
From this study, it can be concluded that education may be the most important factor having a direct and indirect effect on the outcomes. However, for better oral health, powered toothbrushing and inter-dental cleaning should not be neglected.
本研究旨在确定影响两个时间点之间牙齿数量和健康或填充表面数量变化的因素。
分析了基于人群的研究的重复横断面数据，即德国口腔健康研究（DMS-III 与 DMS-V）、波美拉尼亚研究（SHIP-START-0 与 SHIP-TREND-0）和延雪平研究（2003 年与 2013 年）。为了评估结果（牙齿数量、健康表面数量和填充表面数量），构建了 Oaxaca 分解模型。
检查之间的牙齿数量增加（DMS：成年人+2.26，老年人+4.92；SHIP：+1.67；延雪平：+0.96）。教育和口腔保健意识的提高对所有结果都有积极的影响。电动牙刷和牙间清洁的增加对 DMS 的影响较大（成年人：+0.25 颗牙齿，+0.78 个健康表面，+0.38 个填充表面；老年人：+1.19 颗牙齿，5.79 个健康表面，+0.48 个填充表面）。SHIP-START-0 与 SHIP-TREND-0 之间，牙间清洁减少了 4%，这对结果产生了负面影响。
从本研究可以得出结论，教育可能是对结果具有直接和间接影响的最重要因素。然而，为了更好的口腔健康，不应忽视电动牙刷和牙间清洁。
