功能牙数和不同的修复行为对老年人幸福感的影响

目的 探讨功能牙数和不同的修复行为对老年人幸福感的影响.方法 以WHO推荐的幸福感指数量表（WHO-5）作为幸福感测评工具,对某地区老年人进行调查.采用协方差分析去除混杂因素,LSD检验进行WHO-5得分的组间两两比较.结果 （1）协方差分析结果表明,不同的功能牙数、修复行为的老年人幸福感指数平均得分不完全相同（F=21.547,141.219; P＜0.001）.（2）LSD检验结果表明,功能牙数目0～4、5～9、10～14、15 ～ 19、20以上老年人WHO-5调整后得分均值分别为（11.786±5.270）分,（15.724±4.036）分,（15.934±3.957）分,（18.941±2.616）分,（23.390±6.951）分,除功能牙数目5～9和10～14组间差异无统计学意义（LSD-t=-0.536,P=0.593）外,其余得分组间均差异有统计学意义（均P＜0.01）;无需修复、完全修复、未完全修复、异常修复、未修复老年人WHO-5调整后得分均值分别为（22.848±8.068）分,（23.056±4.772）分,（20.647±2.660）分,（14.565±2.914）分,（14.872±7.313）分.未修复、未完全修复、完全修复老年人的WHO-5调整后得分差异有统计学意义（P＜0.01）;未完全修复和异常修复得分均值差异有统计学意义（LSD-t=13.108,P＜0.01）.未修复和异常修复老年人调整后的WHO-5调整后得分差异无统计学意义（LSD-t=-0.696,P=0.486）;无需修复和完全修复老年人WHO-5得分差异无统计学意义（LSD-t＝-0.340,P=0.734）.结论 老年人的幸福感和功能牙数、不同的修复行为有关.

The impact of the number of functional natural teeth and different oral restoration behaviors on well-being of elderly

Objective To study the impact of the number of functional natural teeth （FNT） and different oral restoration behaviors on well-being of the elderly.Methods The elderly residents of Guangzhou Haizhu District were acted as respondent,WHO-5 Scale was the measurement instrument of well-being.Analysis of covariance was used to correct confounding factors and analyze the corrected data,and then it was compared by LSD Test.Resuits （1） The results of analysis of covariance showed that,average scores on WHO-5 Scale were not all the same among different groups which were divided by different number of FNT or different oral restoration behaviors （Respectively：F=21.547,P〈0.001 ; F=141.219,P〈0.001）.（2） The results of LSD Test showed that,although there were no statistical differences in corrected average scores between group with 5-9 FNT and group with 10-14 FNT （LSD-t=-0.536,P=0.593）,differences had statistical senses between other groups（P〈0.01）.All scores were ordered from the least to the most number of FNT,and they were （11.786±5.270）,（15.724±4.036）,（15.934±3.957）,（18.941±2.616） and （23.390±6.951） respectively.It also showed that,there were no statistical differences in corrected average scores between the perfect oral restoration behavior group,the imperfect oral restoration behavior group and the no oral restoration behavior group（respectively：（23.056±4.772）,（20.647±2.660）,（14.872±7.313） ; P〈0.01）.Statistical differences were also found in corrected average scores between the imperfect oral restoration behavior group and the abnormal oral restoration behavior group （respectively：（20.647 ±2.660）,（14.565±2.914）;LSD-t=13.108,P〈0.01）.No statistical differences were found in corrected average scores between the no oral restoration behavior group and the abnormal oral restoration behavior group（respectively：（14.872±7.313）,（14.565±2.914） ; LSD-t=-0.696,P〈0.01）.The differences in corrected average scores between the needless oral restoration behavior group and the perfect oral restoration behavior group also showed no statistical significance （respectively：（22.848± 8.068）,（23.056± 4.772） ; LSD-t =-0.340,P =0.734）.Conclusion Well-being of the elderly may be associated with number of FNT and oral restoration behaviors.
