다국어 초록 (Multilingual Abstract)

The present study purposed to survey the level of oral health and to examine relevance between oral health and quality of life among the elderly and for this purpose, we had individual interviews using a structured questionnaire with 336 elderly who were using seniors’ centers in Daejeon Metropolitan City during the period from the 9th to 31st of July, 2007. The questionnaire used in the research was composed of questions on the socio-demographic characteristics about the subjects of the study, their perceived health status and perceived oral health status, their subjective symptoms about oral health and oral status, dry mouth, GOHAI index and OHIP-14 index, etc. The major results are as follows.
1. Among the subjects, 43.4% and 25.6% perceived that they were good in health and oral health, respectively, and 41.1% and 60.7% perceived that they were poor in health and oral health, respectively. Thus, the percentage of those who perceived that their oral health was poor was highest.
2. As to the subjects’ tooth condition, 21.8% of the male elders and 33.2% of the female elders did not have teeth, and the number of natural teeth was less than 20 in 63.6% of the male elders and 75.7% of the female ones. Thus, there are significantly more toothless female elders and the number of female elders' natural teeth was significantly less than that of male ones'.
3. Dry mouth was observed in 21.8% of the male elders and 48.7% of the female ones, So female elders showed significantly higher frequency of dry mouth.
4. In the factor analysis of GOHAI index, it was significantly higher in female elders, those of low education level, those under medical aids, those of low monthly average allowance level, those with a large number of medication, those who replied that their health status and oral health status perception were poor, those who have higher perception of dental care needs those with pains in the temporomandibular joint and gingival bleeding, and those with teeth fewer than 20 and dry mouth.
5. In the factor analysis of OHIP-14 index, it was significantly higher in female elders, those of low education level, those under medical aids, those of low monthly average allowance level, those with a large number of medication, those who replied that their health status and oral health status perception were poor, those who have higher perception of dental care needs those with pains in the temporomandibular joint, those gingival bleeding, and those with a small number of remaining teeth, those edentulous and those dry mouth.
6. As to the correlations of GOHAI and OHIP-14 with other factors, age was in a negative correlation with the number of natural teeth, a positive correlation with dry mouth, and a positive correlation with health status and oral health status perception, perceived oral health was in a positive correlation with the number of natural teeth, health status and oral health status perception were in a negative correlation with dry mouth, perception were in a negative correlation with dry mouth, GOHAI and OHIP-14. The number of natural teeth was in a negative correlation with dry mouth, GOHAI and OHIP-14. Dry mouth was in a positive correlation with GOHAI and OHIP-14 and GOHAI was in a strong positive correlation with OHIP-14.
7. In order to measure the explanatory power of independent variables related to GOHAI, we conducted hierarchical multiple regression analysis using 3 models. According to the results, GOHAI was in a significant correlation with health insurance type in Model I. In Model II, it was in a significant correlation with health status and oral health status perception and the recognition of necessity for perception of dental care needs. In Model III, it was in a significant correlation with pain in the temporomandibular joint, the number of natural teeth and dry mouth and the explanatory power of these variables for Model III was 26.6%.
8. In order to measure the explanatory power of independent variables related to OHIP-14, we conducted hierarchical multiple regression analysis using 3 models. According to the results, OHIP-14 was in a significant correlation with gender, academic qualification and health insurance type in Model I. In Model II, it was in a significant correlation with health insurance type, subjective health and the recognition of necessity for perception of dental care needs. In Model III, it was in a significant correlation with pain in the temporomandibular joint, gingival bleeding, the number of natural teeth and dry mouth and the explanatory power of these variables for Model III was 27.6%.
The results of this study presented above suggest that in the elderly population their quality of life is affected by demographic characteristics, health, oral health perception, subjective oral symptoms and oral health condition. Accordingly, for the healthy maintenance of elders’ natural teeth, it is considered necessary to develop and execute continuous oral health management systems and oral health education programs that promote preventive activities and enhance the perception of oral health.
