福建省部分城乡中老年人群咬合支持情况抽样调查报告

An epidemiological investigation of state of occlusal support in Fujian

目的:了解福建省中老年人群咬合支持的现状,为中老年人口腔健康的防治工作提供参考依据。方法:采用多阶段、分层、等容量、随机抽样的方法对福建省中老年人咬合支持情况进行了抽样调查。结果:福建省城市地区中年人群的平均咬合接触牙对数为12.90,有98.06%的中年人有8对以上牙齿有咬合,咬合完整率为54.31%,后牙咬合完整率为59.44%。中年组农村地区的总咬合对数平均数、后牙咬合对数平均数、咬合完整率均高于城市地区。在老年组,平均咬合对数为6.19,有29.86%的受检者口腔内没有咬合接触牙,44.72%老年人的口腔内有8对以上的咬合接触牙。老年组后牙平均咬合对数为2.90,仅有10.69%受检老年人的后牙咬合接触完整。老年组咬合对数的各项指标,除了老年男性后牙咬合完整率高于女性,其余均无城乡与性别的差异。结论:老年人群的咬合支持状态总体上远较中年人群差,福建省超过半数的老年人的牙列功能低于可接受的水平,加大预防保健的力度,保护和改善老年人的咬合支持状态刻不容缓。

Objective：To investigate the state of occlusal support among middle-aged and the elder people in Fujian province and to provide a scientific basis for raising the oral health-related quality for them. Methods：The methods of poly-stage, layering, isasteric and randomize sampling were used in the investigation. 36 villages from 6 cities were examined in the epidemiological investigation. From every village, the examiners collected the information about the state of occlusal support of 40 people randomly （20 from 35 to 44-year-old, the other 20 from 65 to 7d-year-old）. Results：For middle-age people, the occluding tooth pairs were 12.90 on average in urban in Fujian province. 98.06% of them had more than 8 occluding teeth pairs. The rate of complete occlusion was 54.31% and it was 59.44% for molars and premolars. The rate of complete occlusion, the occluding tooth pairs on average for dentition and molars in suburb were higher than in urban for middle age people. In the elder , the occluding tooth pairs were 6.19.29.86% of the examined had no occlusion in their mouth. 44.72% of the examined old person had 8 or more occluding teeth pairs. The occluding tooth pairs on average were 2.90 for old people and only 10.69% of them had complete occlusion. The rate of complete occlusion of old males was higher than old females. Other indexes had no statistical significant difference , either in urban and suburb or in male and female. Conclusion：The state of occlusal support in the elder was far lower than that in the middle-age. It was more than half of elderly in Fujian province, whose occlusal support function were not acceptable. It is necessary to propagate oral health knowledge, especially in old person. We should protect and improve the state of occlusal support to raise the oral health-related quality for them.
