Objectives: The study aimed to investigate the relationship between depression and number of present teeth in Korean elderly individuals. Methods: Data for this cross-sectional survey was obtained from the records of the sixth Korea National Health and Nutrition Examination Survey (KNHANES). The subjects were 1,199 Korean elderly individuals above 65 years of age. The survey and examination data were used for the independent variables. The KNHANES included health status, nutrition survey, and oral examination. $x^2-test$ was performed to identify the characteristics of depression and number of teeth present according to the characteristics of the study subjects. Logistic regression analysis was also performed to identify the relationship between depression and number of teeth present. The statistical significance level wa sset at 0.05. Results: The prevalence of depression in the subjects was 14.8%. There were statistically significant differences in the prevalence of depression, depending on gender (p<0.001), education level (p=0.001), income (p=0.001), spouse status (p<0.001), and alcohol consumption (p=0.020). The association between depression and the number of teeth present showed statistically significant difference after adjustment (p=0.040). Conclusions: Depression in elderly individuals was closely related to the number of teeth present. Therefore, public health policies for improving oral health should be established to prevent depression.

The esthetic factor for the esthetic prosthesis were studied on 300 persons. The praaticipants were 150 students registered under the Deparment of Dental Laboratoy Technology, Jisan Junior College at the present day of June, 1995 and their mothers. The results were as follows; 1. The number of persons with 28 teeth in their oralcatity was highest(P<0.01). They complained that they have only 28 teeth bacaues of the loss(deficiency) fo teeth due to their impacted teeth and dental caries. 2. The presons with feelings of dissatisfaction were large in number(P<0.01). They were dissatisfied with an abnormal tooth form(33.5%), tooth position(31.7%), tooth color(31.1%), and tooth size(3.7%) in order(P<0.01). 3. In their facial form, the most numerous were men with square form and women with ovoid form(P<0.01). Among the whloe number fo facial forms it appeared to decresae in the order of ovoied(41.8%), square(32.7%), square+tapered(20.5%), and tapered form(5%)(P<0.01). In a profile form, the most numerous were men with A form and women with B. Among the whole participants the most numerous were persons with B form and persons with A and C form were next in oder of numbers(P<0.01). 4. In discoloration of teeth, the most numerous were persons who have no discoloration. 5. In the esthetic recovery of anterior prosthesis the color matching of proximal teeth was not correct, but the outline of proximal teeth was to be reproduced correctly. 6. In the diastema of teeth, the number of persons who have no diastema was higher than that of persons who have a disatema(P<0.01) Among the persons who have diastema the most numerous were persons who have a diastema, and next were 2, 4, 3 and 5 diastemas in order. 7. In a meeting point of the midline of the body and the tooth the number of person hanving a meeting point was higher than that of persons who did not fit each other(P<0.01). The bias direction of midline teeth appeared to be affected by chewing direction, prosthesis location, and posterior location. 8. The length and width of teeth in the tooth size were suitable(P<0.01). The number of persons who have central teeth longer than lateral teeth was high(P<0.0). 9. In the results of smile analysis, the line form connected with incisal edge of upper canine were parallel(P<0.01). When smile the location fo upper lips should be in accord with the central area of teeth(P<0.01) and lower lip should be atteched to the edge of anterior teeth in order to be esthetic. 10. Among the number of upper teeth we can see the most numerous were 8 teeth and next were 10, 6 and 12 in order.

Korean society is experiencing a very rapid change in population aging. Oral diseases, including dental caries and periodontal disease, are usually cumulative and make oral health worse with age. Preventing tooth loss through the prevention and treatment of caries and periodontal diseases are essential for retaining oral function later in life. This study aimed to identify the trend in oral health status among elderlies over 65 years old, using major oral health indicators of Health Plan 2020. The fifth, sixth, and seventh Korea National Health and Nutrition Examination Survey (KNHANES V, VI, VII) were used in the present study to estimate the number of remaining natural teeth, the rate of 20 or more natural teeth, the rate of chewing difficulty, and the rate of oral health check-up of elderly. The number of remaining natural teeth increased from 15.6 in 2010 to 17.1 in 2015, and the rate of 20 or more natural teeth also increased from 45.8% in 2010 to 53.7% in 2015. The rate of chewing difficulty was similar but declined a little from 44.3% in 2010 to 42.9% in 2017. Finally, the rate of oral health check-ups of the elderly increased significantly from 12.2% in 2010 to 21.1% in 2017.

Purpose : The present study aimed to investigate the of the based on their oral health status and the study findings will provide the basic data for establishing future oral health related policies for the elderly. Methods : A total of 50 elderly participants were selected for the study. Oral examinations were performed by a single trained dental hygienist, the oral health status was classified according to the use of dentures, presence of temporo-mandibular joint (TMJ) noise, presence of TMJ pain, presence of trismus, presence of preferred chewing, and number of residual teeth. An oral health-related survey using the in-person interview method was conducted by two dental hygienists and 30 types of foods were selected for the assessment of chewing ability. For data analysis, the Mann-Whitney U test and Spearman's Rho analysis were performed to investigate the association between oral health status and chewing ability. Result : The results of the present study revealed that there was a statistically significant positive (+) correlation between the number of residual teeth and chewing abilities. In other words, as the number of residual teeth increased, chewing ability increased as well, with the differences being statistically significant. Conclusion : Improvement of oral health in the elderly is a fundamental aspect of healthy aging. Therefore, the implementation of more efficient oral health care policies for the elderly is required as We move toward a super-aged society.

The purpose of this study was to confirm the relevance of dental health capacity and pulmonary function status. The subjects of this study were adults aged 40 years and older, who participated in pulmonary function and oral examinations. The data used for this study were raw data from the sixth Korea National Health and Nutrition Examination Survey (2013~2015). Statistical analysis was performed by analysis of complex sample survey data. The results were as follows: First, restrictive and obstructive patterns were more prevalent among males than females. They were even worse in older subjects. Approximately 67% of smokers had obstructive pattern. Second, there was a relevance between dental health capacity and pulmonary function status. The functioning teeth index, number of present teeth, and number of sound teeth (ST), which are indicators of dental health, declined with decreased pulmonary function. The number of missing teeth (MT) increased as the pulmonary function deteriorated (p<0.05). Third, the relevance between dental health capacity and pulmonary function status after stratifying the life-long smoking experience was statistically significant in the tissue health (T-health) index and ST among non-smokers. The relevance between dental health capacity and pulmonary function status after stratifying the life-long smoking experience was statistically significant (p<0.05) for the T-health index, ST, and MT among smokers. However, there was no relevance between dental health capacity and pulmonary function status after stratifying the life-long smoking experience and adjusting confounding variables. In conclusion, there was a relevance between dental health capacity and pulmonary function status after confounding variables were adjusted. However, there was no relevance between dental health capacity and pulmonary function status after stratifying the life-long smoking experience and adjusting confounding variables.
