Objectives: The purpose of the study is to evaluate the effect of continuing dental care program by elementary school dental clinic in Gimcheon from 2008 to 2013. Methods: The subjects were experimental group of 152 students from three elementary schools having dental clinics and control group of 136 students from three elementary schools of no dental clinics. The six dentists in Gimcheon community health center carried out the regular dental checkups in the elementary schools and four dental hygienists recorded the dental examination results. After receiving WHO dental survey guideline education, the examiners used dental mirror and dental probe under the natural light. The contents of the survey included dental caries in the deciduous and permanent teeth, malocclusion, remaining ratio of sealant, treatment, and follow up. Results: DFT index by grade showed that 3.71 in experimental group and 4.56 in control group and it was remarkable in the 3rd grade. Thus. DFT index in the experimental group was lower than that of control group (p<0.05). DT index by grade was 0.63 in experimental group and 1.28 in control group marked in the 6th grade. DT index in the control group was higher than that of the experimental group (p<0,001). DFT index and DMFT Index by grade showed no significant difference between the control group and the experimental group. DFT and DMFT Index of the control group in the 3rd and 6th grade were lower score than those of experimental group. DFT and DMFT index in the third and 6th grade showed no significant difference between the control group and the experimental group. The remaining ratio of the sealant was 4.89 experimental group in the 6th grade. The remaining ratio of the sealant in the experimental group was higher than that in the control group. Conclusions: The continuing dental care program in the elementary school is very effective method in the treatment of oral disease in the elementary school children. The oral health care and prevention for the elementary school children should be implemented and carried out continuously.

The purpose of this study was to reveal relationship between positive illusions and oral health promotion behaviors. Positive illusions was composed of positive self-perception, exaggerated sense of personal control, and unrealistic optimism. We thought these factors affect to the oral health behaviors. For this study, 307 collegians in Ulsan, Yangsan are participated in this study. The data was subjected to confirmatory factor analysis and structural equation modeling with SPSS 18.0, AMOS 18.0. In conclusion, we obtained the next results. First, positive illusions has a statistically significant with oral health promotion in correlation analysis(p<0.05). Second, Structural equation modeling fit index was well fitted as $X^2$=100, df=112, P=0.893, RMR=0.021, GFI=0.969, AGFI=0.943. Only positive self-perception and exaggerated sense of control has a statistically significant(P<0.05). Third, the group of the highest positive illusions has a statistically significant in all factors(P<0.05), the other hand, the group of the lowest positive illusions has not statistically significant in all factors(P>0.05). So, as this results we concluded that the self-confident or activated persons were very well performed in oral health promotion behaviors.

Objectives: The aim of this study was to examine the relationship between periodontitis, obesity, and health behavior according to sex and age in Korean adults. Methods: Data on 11,032 adults aged 19-79 years were obtained from the 7th Korea National Health and Nutrition Examination Survey (KNHNES). We used multivariate logistic regression analysis to test for associations. Results: The final model that was adjusted for demographic characteristics and health status, showed a higher risk of periodontitis with increasing body mass index (BMI), smoking, failure to use oral care products, and no dental check up. In the sub-group analysis, only smoking was significant in the 19 to 39-year-old age groups. In the 40 to 64-year-old age group, a BMI of 30 or higher, and smoking, use of oral care products, and dental check-up were significantly associated with periodontitis. In the female group, BMI, smoking, use of oral care products, and dental check-up were significantly related to periodontitis. However, in males, only smoking was significant. Conclusions: Obesity management can be helpful for periodontal health as periodontitis prevalence in adults increased as BMI increased. For periodontal health, an oral health program should include smoking cessation and the use of oral care products and dental check up as part of obesity management.

This research was conducted in order to collect and arrange an oral health information needed the school oral hygiene as a part of a long term local community oral hygiene development to promote the oral health of the residents in Sung-Nam. After gathering the information of oral hygiene of 12-year old schoolchildren in Sung-Nam, these conclusions are reached: (1) The experience of dental caries in permanent teeth of 12-year old schoolchildren in Sung-Nam was revealed 74.7%, proportion of children with one or more caries in permanent teeth was 36.2%, and DMFT index was 2.75. (2) DT rate was 28.4% in total and regional difference has been revealed. In Sujung-Gu, DT rate was 36,8% and this was nearly as twice as 19.8% in Bundang-Gu. (3) For permanent teeth, fillings requirements for one surface were 26.6%, more that two surfaces were 13.3%. In addition, artificial crown treatment requirements were 1.8%, dental pulp treatment was 5.3%, and extraction requirement was 2.2%. In contrast, holders of pit and fissure sealant were only 27.1%. (4) In Sung-Nam, oral hygiene education campaign for 12-year old schoolchildren needs to be continued. Simultaneously, early stage examination and preventive approaches for decayed teeth such as pit and fissure sealant need to be considered for schoolchildren who have high tendency of dental caries and who are in areas which show high percentage of dental caries occurrence.

Objectives: This study aimed to examine the effect of the Oral Health Education Program (OHEP) on the change in the children's brushing behavior and reduction in the dental plaque index (PI) and to identify changes in their parents' perception of oral health. Methods: The OHEP was applied 44 children recruited from two childcare centers. We conducted a self-reported survey of the parents at baseline and evaluated the oral conditions of the children at baseline and after 5 weeks. Their brushing behavior was assessed once a week during the OHEP intervention period and daily at home thereafter. We measured the PI after a 12-week follow-up and performed repeated measures analysis of varience. Results: The average PI score of children significantly decreased at week 5 as compared to the baseline (1.90±0.53, p<0.001), despite a substantial increase in week 12 (2.67±0.08, p<0.001). OHEP was effective in reducing the PI score and modifying their brushing behavior. Conclusions: OHEP effectively modified the brushing the behavior of the children. Therefore, it is necessary to develop and expand a systematic oral health education program to promote self-management of oral health in children.

Objectives: This study aimed to confirm the association between cognitive function and oral health status in the elderly. Methods: In this study, 5,794 respondents, aged 55 or older, who had participated in the 7th aging research panel survey were used. Statistical analyses were performed using a complex samples cross-tabulation analysis, complex samples general linear model, and a complex sample multinomial logistic regression analysis. Results: After analyzing the cognitive function of the elderly according to their oral health conditions, it was found that suspicions of dementia (19.6%) and cognitive function decline (25.9%) were more common for those who wore dentures than for those who did not wear dentures (p<0.001). Compared to those who did not wear dentures, those who wore dentures were linked to a 1.665 times higher suspicion of dementia (p<0.001). In comparison, cognitive decline was 0.964 times lower when the number of natural teeth increased by 1, and it was 0.941 times lower when the oral health evaluation index for the elderly increased by 1 point (p<0.001). Conclusions: As a result of this study, it was confirmed that cognitive function and oral health status are related in the elderly. Therefore, systematic measures for oral health management and oral health promotion should be prepared in tandem with awareness of possible cognitive decline in the elderly.

This study surveyed and analyzed on the relationship between obesity and oral health in early child hood and on the oral health realities targeting 90 young children at K Child Care Center where is located in Gangwon-do Province from 10 to 11, June, 2011. As a result, DMF rate accounted for 56.7%. D rate accounted for 42.2%. The young children with the higher age, height in 100~110cm, and weight in 25 kg were indicated to be higher in DF rate than other toddlers. The young children with height in 110~115 cm were indicated to be higher in prevalence of dental caries in deciduous teeth than other young children. It was indicated that the young children in the higher age and weight leads to the higher in DFT index and DFS index. It was indicated that the young children in the more overweight leads to the higher in the index of dental caries in primary teeth, the filling deciduous teeth index, DFT index, DMFS, and DFS index. Accordingly, the child care center needs to systematically perform the oral health education and oral health management for young children, to allow Young children to acquire right food habit, and to pay close attention even to selecting snack.

This study analyzed the tooth brushing behavior and oral health status of foreigner immigrant workers and obtained the following results. Statistical significance based on different general characteristics. Gender, educational background, period of stay, health insurance, medical expense coverage, and whether or not one has friends or regular gatherings were significant traits for frequency, while age, marital status, income, and health insurance were traits for part (p<0.05). Statistical significance (p<0.05) was found in marital status and health insurance for time used to brush teeth, period of stay and whether or not one attends a regular gathering for tooth brushing training, and gender, educational background, period of stay, roommate status, medical expense coverage, and whether or not one attends a regular gathering for supplemental oral product usage. The averages of decayed, missing, and filled teeth (DMFT) index and community periodontal index of treatment needs (CPITN) for general characteristics were 6.98 and 3.03 respectively, and gender, roommate status, income, health insurance for DMFT index, and gender, age, marital status, educational background, roommate status, income, health insurance for CPITN were statistically significant (p<0.05). Tooth brushing frequency and part showed statistical significance (p<0.05) for DMFT index based on tooth brushing behavior, while tooth brushing part and time used to brush teeth were significant for CPITN. DMFT index was high at 8.34 for '3 times or more' in tooth brushing frequency, while DMFT index was high at 7.91 and CPITN was low at 2.94 for tooth brushing part. '3 minutes or longer' in time used to brush teeth was the lowest in CPITN at 2.88. As a result of analyzing the correlation between tooth brushing behavior and DMFT index, CPITN, tooth brushing frequency and part in DMFT index, and tooth brushing part and time used to brush teeth in CPITN showed significance (p<0.05). Based on the above results, we must promote the significance of brushing teeth and implement continuous training for correct tooth brushing management to enhance the oral health of foreign immigrant workers.

The purpose of this study was to provide basic data for healthy and effective dental management by providing the knowledge and information on periodontal health promotion as well as high dental health interests, by doing a comparative analysis of the effect of dental health knowledge and oral hygiene management skills of people in their 20s on periodontal health status assessment, to find periodontal disease early and prevent it targeting 130 adults in their 20s who visited dental hygienic lab for comprehensive dental hygiene care and treatment from September 25 to October 30. The data collected used SPSS 18.0. To present the technical characteristics of the data, frequency was used and chi-squared test through cross-analysis was conducted to investigate dental health knowledge and the relevance between the variables of oral hygiene management skills of general characteristics. To examine periodontal health status assessment, t-test and One-way ANOVA and Turkey post-hoc tests were carried out at the 5% significance level. Regression analysis was performed to investigate the impact of dental health knowledge and oral hygiene management skills on dental health status assessment. As a result of this study, as dental health knowledge on tooth brushing of people in their 20s increased, plaque index reduced, as dental health knowledge on periodontal disease increased, plaque index reduced. Dental health status assessment according to a total number of times tooth brushing, tooth brushing methods, whether to use dental hygiene devices, smoking status, drinking frequency per week, whether to have oral health education was statistically significant. To improve the level of dental health knowledge and oral hygiene management skills, oral health education should be strengthened as well as the publicity through the media to have the information on oral health and learn it.

Objectives: The study aimed to analyze the factors affecting the maturity of dental biofilm, which was assessed with quantitative light-induced fluorescence-digital(QLF-D), in a sample of Korean older adults. Methods: This cross-sectional study included 67 participants, aged 65 years and older. All participants completed a questionnaire and tests to measure their manual dexterity and handgrip strength, which are parameters that indicate hand function abilities. To evaluate dental biofilm maturity, 804 surfaces of six index teeth were imaged using QLF-D and then quantified as ${\Delta}R$ values. All data were collected from May 25, 2017 to April 30, 2018. The independent t-test, one-way analysis of variance, and step-wise multiple linear regression were performed to analyze the factors associated with the maturity of dental biofilm (${\Delta}R$). Results: The multivariate linear regression analysis revealed that the factor most strongly related to dental biofilm maturity(${\Delta}R$) was manual dexterity (${\beta}=-0.326$), followed by handgrip strength (${\beta}=-0.303$) and use of interdental cleaning devices (${\beta}=-0.283$) (p<0.05). Conclusions: Manual dexterity, handgrip strength, and use of interdental cleaning devices are factors that can predict dental biofilm maturity in adults aged 65 years or older. Therefore, the hand function of a patient should be evaluated first, before assessing the oral hygiene status of the patient or providing him/her with oral health education, and the dental hygienist should provide differentiated oral hygiene care depending on the patient's hand function ability. Finally, dental hygienists should help older adults to recognize the importance of auxiliary oral hygiene devices such as interdental brushes and keep motivating them to use the devices more frequently.
