To evaluate pattern of change in periodontal variables and tooth loss in a twelve-year follow-up study of older adults living in Sweden.
In a prospective population study of older adults, a clinical examination and radiographic dental examination were performed at baseline (2001-2003) and after 12 years (2013-2015). In 375 individuals, the number and proportion of sites with a distance ≥4 mm and ≥5 mm from cemento-enamel junction to the bone level, the number and proportion of teeth with pockets ≥5 mm and number of teeth lost were calculated. Dental caries was registered. Periodontitis was defined as having ≥2 sites with ≥5 mm distance from cemento-enamel junction to the marginal bone level and ≥1 tooth with pockets ≥5 mm.
A diagnosis of periodontitis was evident in 39% of the individuals, and 23% of the individuals lost ≥3 teeth over the study period. The proportion of sites with ≥4 mm and ≥5 mm bone loss increased with age, while the proportion of teeth with pockets remained stable. Periodontitis was the strongest predictor for losing ≥3 teeth, OR 2.9 (p < .001) in the final model.
Periodontitis is a risk factor for future tooth loss among older adults.
评估瑞典老年人为期 12 年的随访研究中牙周变量和牙齿缺失的变化模式。
在一项针对老年人的前瞻性人群研究中，在基线（2001-2003 年）和 12 年后（2013-2015 年）进行了临床检查和放射学牙科检查。在 375 名个体中，计算了距离釉牙骨质界≥4mm 和≥5mm 的位点数量和比例、≥5mm 牙周袋的牙齿数量和比例以及牙齿缺失数量。记录了龋齿。牙周炎的定义为≥2 个位点距离釉牙骨质界至边缘骨水平的距离≥5mm，且≥1 颗牙齿的牙周袋≥5mm。
39%的个体被诊断为牙周炎，23%的个体在研究期间失去了≥3 颗牙齿。≥4mm 和≥5mm 骨损失的位点比例随年龄增长而增加，而有牙周袋的牙齿比例保持稳定。牙周炎是未来牙齿缺失的最强预测因素，最终模型中的 OR 为 2.9（p<0.001）。
牙周炎是老年人未来牙齿缺失的一个危险因素。
