ABSTRACT

Objectives : In order to contribute to understanding adults’quality of life, promoting oral health and improving the quality of life, we have tried to understand the relevance of OHIP-14 and EQ-5D by researching and analyzing the general characteristics, objective oral health condition, subjective oral symptoms, oral health behavior,OHIP-14, EQ-5D, etc. targeting ruralists in a certain rural region. Methods : This research was conducted from July 17th, 2010 to August 16th, 2010 targeting 600 residents in Goryeong-gun, Gyeongsangbuk-do, aging over 40. The data has been analyzed using Mann-Whitney U test,Kruskal-Wallis test and hierarchical multiple regression through SPSS Win Program 18.0 version. Results : 1. OHIP-14 based on general characteristics showed lower oral health-related quality of life on the following cases: women(p=0.004), older(p<0.001), lower scholastic ability(p<0.01), lower average of average spending money(p<0.001), higher number of chronic disease (p<0.001), less drinking(p=0.012) and lower cognition of subjective oral health and health status(p<0.001). 2. OHIP-14 based on oral health behavior showed lower oral health-related quality of life on the following cases: no periodic oral check-up(p<0.001), less experience of oral health education(p<0.001), lower frequency of tooth-brushing(p=0.042) and horizontal tooth-brushing method(p <0.001). OHIP-14 based on oral health status and subjective oral symptom showed lower oral health-related quality of life on following cases: number of existing tooth less than 20(p<0.001), the number of missing teeth more than 9(p<0.001), DMFT (Decay, Missing, Filling Teeth) index more than 18(p<0.001), wears denture (p <0.001), edentulous(p<0.001), have xerostomia (p<0.001) and have chewing discomfort(p<0.001). 3. EQ-5D based on general characteristics showed lower health-related quality of life on the following cases: women(p <0.001), older (p<0.001), lower scholastic ability (p<0.001), lower average of average spending money(p<0.001),higher number of chronic disease(p<0.001), non smoking and drinking(p<0.001, p=0.008) and lower cognition of subjective oral health and health status(p<0.001). 4. EQ-5D based on oral health behavior showed lower healthrelated quality of life on the following cases: no periodic oral check-up(p<0.001), less experience of oral health education(p<0.001), and horizontal tooth-brushing method(p<0.001). EQ-5D based on oral health status and subjective oral symptom showed lower health-related quality of life on following cases: number of existing tooth less than 20(p<0.001), the number of missing teeth more than 9(p=0.044), DMFT (Decay, Missing, Filling Teeth)index more than 18(p<0.001), wears denture(p<0.001), edentulous(p=0.002), have xerostomia(p<0.001) and have chewing discomfort(p<0.001). 5. Factors affecting OHIP-14 were gender, age, cognition of oral health, cognition of health, number of existing teeth, condition of the set of teeth, xerostomia and chewing discomfort, and the of reliability (how well it explains) the final model was 48.7%. EQ-5D showed relevance on gender, age, presence of chronic disease, cognition of health, xerostomia, chewing discomfort and oral health-related quality of life, and the reliability of the final model was 42.9%. Conclusions : In order to improve the quality of life of ruralists, oral health needs to be improved or remained by increasing the rate of possession of the existing teeth and preventing the loss of teeth. In order to do so,improvement of accessibility of dental clinic, change of direction from treatment-centered to prevention-centered health care system, development of oral health education program and various oral health care policies which would vitalize continuous oral health care system are considered to be necessary.
