To evaluate the impact of oral health behaviours and oral habits on the number of remaining teeth in older Taiwanese dentate adults.
Subjects comprised dentate patients (mean age, 60.0 ± 9.9 years) in Taiwan. Information on demographic data, oral health behaviours, oral habits and self-perceived health status was collected via self-administered questionnaires and dentition status was assessed by oral examination. Multiple logistic regression analyses were used to determine variables correlated with the low dentition group (subjects with less than 20 natural teeth or 8 functional tooth units).
The analysis showed that the low dentition group was more likely to be older and to exhibit low educational levels, less frequent use of dental floss, more common smoking habits, poor self-perceived dental health and to be exbetel- nut chewers. In addition, the low dentition group was less likely to be current betel-nut chewers.
These results underscore the importance of the use of dental floss and confirm the adverse effects of smoking on dental health. Hence, the dental profession should continue to encourage proper oral health behaviours and oral habits.
评估口腔健康行为和口腔习惯对台湾老年有牙成年人剩余牙齿数量的影响。
研究对象为台湾有牙患者（平均年龄60.0±9.9岁）。通过自填问卷收集人口统计学数据、口腔健康行为、口腔习惯及自我感知健康状况等信息，并通过口腔检查评估牙列状况。采用多元逻辑回归分析确定与低牙列组（天然牙少于20颗或功能性牙单位少于8个的受试者）相关的变量。
分析表明，低牙列组更可能年龄较大、教育水平较低、使用牙线频率较低、吸烟习惯更普遍、自我感知牙齿健康状况较差且曾是嚼槟榔者。此外，低牙列组当前是嚼槟榔者的可能性较小。
这些结果强调了使用牙线的重要性，并证实了吸烟对牙齿健康的不利影响。因此，牙科行业应继续鼓励正确的口腔健康行为和口腔习惯。
