Information on the significance of dental care in older adults is limited. We hypothesized that regular dental visits has an effect on the number of remaining teeth and periodontal conditions in older subjects.
1020 randomly selected individuals age 60 - 96 from the Swedish National Study on Aging and Care Blekinge received a comprehensive oral health examination.
Dentate women and men had, on average 18.4 teeth (SD +7.6,) and 18.9 teeth (SD + 7.5) respectively (NS). In the youngest group (60 and 66 years old) with less than one dental visit per year, 37% had >20 teeth, compared with 73% among those with at least annual visits. Among the old-old, comparable figures were 1.8 % and 37% respectively. Across age groups, bleeding on probing was 23 %.When adjusting for age, and number of teeth GLM univariate analysis failed to demonstrate an effect of dental visit frequency on alveolar bone loss (p = 0.18), the number of periapical lesions (p = 0.65), or the number of endodontically treated teeth ( p = 0.41). Frequent dental visitors had more teeth than infrequent visitors (p = 0.001).
Tooth loss and alveolar bone loss severity increase with age. Individuals with regular dental visits retained more teeth but the frequency of dental visits had no impact on plaque deposits, gingival inflammation, or alveolar bone levels.
关于老年人牙齿护理重要性的信息有限。我们假设定期看牙对老年受试者的剩余牙齿数量和牙周状况有影响。
从瑞典布莱金厄老龄化与护理全国性研究中随机选取1020名年龄在60 - 96岁之间的个体，进行全面的口腔健康检查。
有牙的女性和男性平均分别有18.4颗牙（标准差 +7.6）和18.9颗牙（标准差 +7.5）（无显著差异）。在每年看牙次数少于一次的最年轻组（60岁和66岁）中，37%的人牙齿超过20颗，而每年至少看一次牙的人中这一比例为73%。在高龄老人中，相应比例分别为1.8%和37%。各年龄组中，探诊出血率为23%。在对年龄和牙齿数量进行校正后，广义线性模型单变量分析未能证明看牙频率对牙槽骨丧失（p = 0.18）、根尖周病变数量（p = 0.65）或根管治疗牙齿数量（p = 0.41）有影响。看牙频繁者比看牙不频繁者牙齿更多（p = 0.001）。
牙齿丧失和牙槽骨丧失的严重程度随年龄增加。定期看牙的个体保留的牙齿更多，但看牙频率对牙菌斑沉积、牙龈炎症或牙槽骨水平没有影响。
