Objectives : The purpose of this study was to provide some information on down-to-earth oral health policy to improve the systemic health involving oral health and the quality of life in Korean adults. Methods : The third-year data of the 4th National Health and Nutrition Survey in 2009 were analyzed, and $x^2$(Chi-square) test was carried out to see whether there would be any gaps in subjective oral health status according to demographic characteristics, systemic health state, frequency of eating between meals and oral health behavior. In terms of the DMFT index, one-way ANOVA was utilized, and then Scheffe post-hoc analysis was conducted. Besides, multiple regression analysis was made to grasp the relationship of oral health behavior to subjective oral health state and the DMFT index. Results : The demographic characteristics, systemic health status and oral health behavior had a significant relationship to both of subjective oral health status and the DMFT index. As a result of analyzing the relationship of oral health behavior to subjective oral health state and the DMFT index, the subfactors of oral health behavior exerted a significant independent influence on subjective oral health status and the DMFT index. Conclusions : The findings of the study suggest that in order to promote the oral health of adults, preventive measures should be taken, and systematic oral health education should be provided. As there is an increase in the elderly population in Korea, the successful implementation of senior oral health plans and the development of oral health programs geared toward adults are both required.

The purpose of this study was evaluation of the oral health of cerebral palsied children by considering the DMFT index. The 31 cerebral palsied children(Male 20, Female 11) participated in the study, and mean age was 11.3 years. All patient were examined for determination of decayed tooth, missing tooth, filled tooth. For children with only deciduous dentition, the dmf system was used; for children with only permanent dentition, the DMF system was used; for children with mixed dentition, a combination of two systems(dmf and DMF) was used. The results were as follows: 1. In the deciduous dentition, dmft index was 11.60.(dt rate ; 83.62%, mt rate ; 12.07%, ft rate ; 4.31 %) 2. In the mixed dentition, DMFT index was 12.25 and dmft index was 10.75.(DT rate ; 90.00 %, MT rate ; 0 %, FT rate ; 10.00 %, dt rate ; 60.53 %, mt rate ; 28.95 %, ft rate ; 10.52 % ) 3. In the permanent dentition, DMFT index was 8.16.(DT rate ; 87.77 %, MT rate ; 11.51 %, FT rate ; 0.72 %)

Objectives: The 2018 Basic Health Research (RISKESDAS), conducted by the Ministry of Health of the Republic of Indonesia showed a high prevalence of dental caries (88.8%) in Indonesia and suggested that smoking tobacco was associated with an increased risk of dental caries. This study analyzed the association between tobacco smoking and dental caries in the Indonesian population. Methods: This was a cross-sectional analysis of secondary data collected from RISKESDAS 2018. The study population included 35 391 Indonesians aged ≥10 years from all 34 provinces. The decayed, missing, and filled teeth (DMFT) index was used to measure dental caries. Smoking status was assessed qualitatively based on smoking activity, and the level of smoking exposure was assessed based on the Brinkman index. A multivariable logistic regression analysis was employed to examine the relationships of smoking status and smoking exposure levels with the DMFT index. Results: Of the population aged ≥10 years, 36% had a DMFT≥8 (females: 37.5%, males: 33.9%). Almost one-fourth (23.4%) were current smokers, and 4.1% were ex-smokers. Furthermore, 26.4% had a Brinkman index ≥400, indicating heavy smoking. According to the multivariate analysis, current smoking status was associated with the risk of DMFT≥8 in males (adjusted odds ratio [aOR], 1.40; 95% CI, 1.27 to 1.55; p<0.001) and overall (aOR, 1.07; 95% CI, 1.00 to 1.14; p=0.037). In females, ex-smoking was associated with a 41% higher risk of DMFT≥8 (aOR, 1.41; 95% CI, 1.07 to 1.84; p=0.014). Heavy smoking was associated with a higher risk of DMFT≥8 in males (aOR, 1.38; 95% CI, 1.25 to 1.52; p<0.001) and females (aOR, 1.24; 95% CI, 1.03 to 1.50; p=0.022). Conclusions: Tobacco smoking was associated with dental caries in the Indonesian population.

This study was tried to suppose the necessity for the participations of the guardians or parents into dental health educations and for developing an educational program on the control of denial health in order to improve the dental health of handicapped children. For this research, it was investigated by a survey on the actual condition of dental health with an object of handicapped children, and simultaneously by analyzing the relationships between the realities of child's dental caries and guardian's acknowledgments and managements with regard to the dental health of the children. The 209 children and their guardians being in special school for the handicapped were surveyed about the actual conditions of dental health from 15 May to 30 June 2000. 1. The average of DT, MT, FT and DMFT index were 2.46, 0.13, 1.18 and 3.78, respectively. 2. As the parents' educational level (p<0.05) and economical incomes were high, the proportions the DMFT index were low (p<0.05). As the father of the handicapped children had a duty, the DMFT index were lower than the opposite case that the father had no duty. However. in the case of their mother, the presence of the duty has not showed any relationships with the DMFT index. And it was revealed that there was a tendency that the lower age of the parents showed the lower proportions (p<0.05) and index (p<0.001). 3. There was no meaningful differences for the DMFT index in the comparison between the children who can brush themselves or not, even though the children who can brush themselves showed relatively and slightly lower DMFT index than the children who can't do it themselves. 4. More frequent observations on the children's dental conditions by the parent resulted in the lower DMFT index(p<0.01). 5. As the parent had relatively more knowledges about the dental disease. the DMFT index were low. Therefore, as it was considered form these results, the parent should be required more positive participations for the improvement of their children's dental health. For promoting this participations, it must be required the development of educational programs and political services for the parent or guardians in order to improve the attendance into the educations.

This document is about immigrant worker who use counseling office for human rights in the Daegu Gumin Church. We researched their oral health state so that we can understand their situation and support them properly. General characteristics of study subjects, habits related to oral health, the oral examination and treatment clinic, participated in oral heath education program were studied by designed administered questionaire. And decay, filling(treatment teeth), missing tooth(lost teeth by dental-caries)was counted by oral examination, and calculated DMFT-index. This study was done from the July, 9, 2006 to Aug. 8, 2006. In a total of 289 immigrant worker, 77.9% of them were men and 22.1% of them were women. 55.7% of their salary was from 1,000,000 won to 1,500,000 won and most of them were working for a fiber industry. Many of them are living in korea for more then three years. DMFT index for men was 2.77 and for women was 4.06 so average of DMFT index was 3.06. 46.7% of them said that they are healthy in oral health state. The question for having difficulty using dental clinic in korea, 65.1% of them said "it is difficult". First reason was a communication problem and second was time. Most of them didn't have a oral health education but 85.1% of them said that they are looking forward to attending oral health education. Immigrant worker had better DMFT index then that of korean blue color worker. But still it is quite difficult for them using dental clinic in korea also cost. It is necessary to support them properly that medical insurance system, medical facilities of quality, medical insurance subscriber beside, made by their language, manual for them. At once, medical service improvement a policy is necessary for immigrant worker in korea.

Objectives: This study was to examined the level of psychosocial factors, dietary habits and DMFT index and to examined the relationship among variables in 12-year-old adolescents. Methods: Participants were 1,831 total students from 14 middle school who lived Seosan with mean age of 12.46 years. Data was collected using a self administrated questionnaire from April 13 to May 24, 2009. Psychosocial factors and dietary habits were measured using the 5-items and 10-items. A trained investigator made an oral examination of them in natural light using a mirror and explorer to determine their DMFT index. Data were analyzed with t-test, one-way ANOVA, and Tukey test, pearson correlation coefficient using the SPSS WIN 15.0 program. Results: Regarding dietary self-efficacy, perceived benefit and perceived barrier degree, the subjects achieved a mean of $3.89{\pm}0.69$, $3.48{\pm}0.63$ and $3.82{\pm}0.63$ out of a maximum 5 points. And the dietary habit degree of subjects achieved a mean of $10.69{\pm}4.02$ out of a maximum 20 points and the DMFT index were $1.91{\pm}2.26$. Dietary habits was positively correlated with psychosocial factors and negatively correlated with DMFT index. And then perceived barrier score were negatively correlated with DMFT index. Conclusion: Based on the findings, dental caries experience is associated with perceived barrier and dietary habits. These results suggest that the implementation of health promotion should be considered for various psychosocial factors and dietary habits in adolescents.

The purpose of this study was to obtain the basic data provide continuous and active dental treatment for the mental handicapped children. The authors studied on the dental caries experience, oral hygiene slates and caries activity test in the mental handicapped children of 9-11 years old, who are housed by rehabilitation school in Kwang-ju and in the 30 normal children of 9-11 years old as a control group. Correlation coefficiency was calculated among the caries experience, oral hygiene states and caries activity test for every children. The obtained results are as follows. 1. The mental handicapped children showed remarkably high score compared to normal children in DMFT index(The Index score was $2.43{\pm}1.98$ in the normal children and $5.26{\pm}4.11$ in the mental handicapped.). 2. Correlation coefficiency was reveled very high score between DT index and DMFT index of the normal children(P<0.01), and the mental handicapped was also high score(P<0.01) between ft index and dmft index. 3. The PMA Index of the mental handicapped children was comparatively higher than the normal(The Index score was $4.03{\pm}4.44$ in the normal children and $7.87{\pm}7.33$ in the mental handicapped.). 4. In the correlation coefficiency between the caries experience and modified snyder test, DMFT index of the normal children was revealed some high score(P<0.05). DMFT index of the mental handicapped was showed remarkably high score(P<0.01).

This study aimed to compare chair-side test results for caries risk assessment and evaluate how well the tests reflect caries experience. The study was conducted on children aged < 6 years in primary dentition. Dental examination of children was conducted to determine the dmft index and subjects were divided into two groups : group I (dmft < 6), group II (dmft > 6). This study used four kinds of test kits (Plaque-check PH kit, Saliva-check buffer kit, Saliva-check mutans kit, Cytoperio analysis system). Saliva buffer capacity was significantly low in the high caries experience group (dmft > 6) and correlated with dmft index. Saliva pH level correlated significantly with saliva buffer capacity. The results showed that plaque pH and saliva pH levels had no correlation with dmft index. The Streptococcus mutans level measured by using the Saliva-check mutans and Cytoperio analysis system did not correlate with dmft index.

Objectives : The purpose of the study is to investigate the relationship between variables associated with oral health status in psychiatric patients and to provide basic information on oral health education program development for the psychiatric patients. Methods : Subjects were 151 psychiatric patients who filled out the structured questionnaire. The data were analyzed for independent t-test, one-way ANOVA and hierarchical multiple regression by using SPSS Win Program 18.0 version. Results : Higher DMFT index was shown in the older age(p<0.001) and low perceived oral health group(p<0.001). Higher DMFT index included no tooth brushing after breakfast(p=0.045), wrong tooth brushing method(p<0.001). Chewing discomfort(p=0.027) and denture(p=0.027) were closely related to higher DMFT index. Bread(p=0.033) and snack(p<0.001) increased DMFT index. Factors affecting oral health status were age, denture, snack and bread. The explanation power of the final model was 29.4%. Conclusions : Dietary control for the psychiatric patients is very important to prevent dental caries. Tooth brushing and use of oral hygiene devices can improve good oral health care. Furthermore, this result can improve the oral health care for the disabled people.

This study was implemented for 84 students of dental hygiene to show the correlation between dental caries experience and improved caries activity test. Dental caries experience for the sample groups was examined and stimulative saliva secreted for 5 minutes was collected into the tube to check saliva secretion rate. Dentocult LB test was executed to observe Lactobacilli colonies after 96 hour cultivation of culture slides moistened with stimulative saliva. Dentocult SM test(screening strip, site strip) was done to measure SM colonies distribution after 48 hour cultivation of culture strips applied with collected saliva and dental plaque respectively, and salivary buffering capacity was checked by means of Dentobuff strip kit. Following conclusions are obtained after examining the relation between Dentocult LB, Dentocult SM, Dentobuff strip test results and DMFT index, salivary secretion rate. 1. Showed no significant difference between Dentocult LB test results and DMFT index, salivary secretion rate. 2. Showed no significant difference between Dentocult SM(screening strip) test results and DMFT index, salivary secretion rate. 3. Showed significant difference between Dentocult SM(site strip) test results and DMFT index(pE0.05), but showed no significant difference between Dentocult SM(site strip) test results and salivary secretion rate. 4. Showed no significant difference between Dentobuff strip test results and DMFT index, but showed a very wide difference between Dentobuff strip test results and salivary secretion rate(pE0.01).
