In order to develop the programme for the improvement of dental health among primary school children, epidemiological survey to examine dental caries status was conducted among primary school children in Changwon, Korea. We sampled 2 primary schools and surveyed children from first to sixth grade aged 6-11 years. All samples were 3,206 consisted of 1,715 males and 1,491 females. We assessed caries prevalence on permanent teeth. 1. Children with caries experience on permanent teeth were 15.1% at 1st grade, 48.2% at 2nd grade, 73.8% at 3rd grade, 75.6% at 4th grade, 76.8% at 5th grade, 77.4% at 6th grade. 2. Decayed, Missing and Filled teeth were 0.31 at 1st grade, 1.16 at 2nd grade, 2.12 at 3rd grade, 2.38 at 4th grade, 2.50 at 5th grade, 2.69 at 6th grade. 3. Decayed teeth among Decayed, Missing and Filled teeth were totally 63.4%. Filled teeth among Decayed, Missing and Filled teeth were totally 36.6%. 4. Community dental health programmmes including water fluoridation, fluoride mouth rinsing, use of fluoride-containing toothpastes and fissure sealants should be developed to prevent dental caries among school children. 5. School incremental dental care programme should be also developed to prevent and treat children's dental caries by use of dentists and oral hygienists.

The term "Oligodontia" or "Hypodontia" have been used to describe variable degrees of reduction in number of teeth. Oligodontia may occur alone or as a result of some syndrome. Although the teeth are derived in part from ectoderm, the current opinion of reason of oligodontia should be reserved for those disorders in which there is abnormal development of one or more ectodermal tissues. 7 year 5 months old female was refered to the department of pedodontics, college of dentistry Yonsei university for evaluation and replacement of absent teeth. She had no special inf.ectious disease in her childhood, and her parents were healthy. She had no special syndrome of ectodermal disorders except the saddle nose, yellow and fine hair, and notched upper anterior central incisor. Panex radiogram was showing 6 anterior primary teeth, 2 permanent first molars and 2 unerupted first bicuspid in mandible. Another permanent teeth were absent. and normal number of primary and permanent teeth in maxilla. Lateral cephalogram showed no special abnormality in growth pattern. We had evaluated lower anterior decayed teeth with jacket resin and chrome steel crown and removable partial denture at missing area. We had got good results for rehabilitation of function and aesthetic.

Objectives: The water fluoridation program has been implemented since 2008, in a region of Geoje City. This study aimed to evaluate the effectiveness of the water fluoridation program on caries prevention in the permanent dentition. Methods: Evaluation surveys were conducted on 8-, 10- and 12-year-old children in the fluoridated and non-fluoridated regions of Geoje City, in 2015. The survey included 834 children from the fluoridated regions and 703 from the non-fluoridated regions. The data obtained from the survey were analyzed using the IBM SPSS statistical package version 23.0. The effectiveness of community water fluoridation in caries prevention was estimated by the differences in the decayed, missing, filled teeth (DMFT) and decayed, missing, filled surfaces (DMFS) scores, between the program and control groups. The mean numbers of fissure-sealed teeth and surfaces were adjusted to reduce their confounding effect. Results: The mean DMFT and DMFS scores (0.69 and 0.91, respectively) of 10-year-olds from the fluoridated regions, after adjusting for the numbers of fissure-sealed teeth and surfaces, were significantly lower than those of the 10 year olds (DMFT: 0.95, DMFS: 1.32) from the non-fluoridated regions. The effectiveness of water fluoridation on caries prevention in the permanent dentition, estimated based on the differences in the mean DMFT and DMFS scores, adjusted for the number of fissure-sealed teeth and surfaces, between the program and control groups of 10-year-old children, was 27.4% and 31.1%, respectively. Conclusions: These results suggest that the effectiveness of water fluoridation on caries prevention in the permanent dentition, in Geoje City was so high that this program should be implemented in other regions in Korea as well.

The purpose of this study was to evaluate the oral health promotion of the disabled persons by voluntary dental services in Ulsan Metropolitan City. Two dentists taken a calibration training for national oral health survey examined the oral health status of 473 disabled persons from two special schools for the disabled children and adolescents, a residential facility and a gymnasium for the disabled persons in 2009-2010. The surveyed disabled persons in the age range was from 7 to 74 years old. Voluntary dentists, oral hygienists and other civilian volunteers had supplied with the oral health care services to the disabled persons at dental clinics of special schools for the disabled children and adolescents, and a dental clinic supported from Nam-Gu Public Health Center in Ulsan Metropolitan City since 1997. The obtained data from these surveys were analyzed with the SPSS statistical package. Among subjects aged 12-14 years, subjects with decayed, missing and filled teeth (DMFT) in permanent dentition was 46.9%; subjects with untreated decayed teeth, 17.2%. The number of decayed, missing and filled teeth in permanent dentition was 1.36. The proportion of decayed components of DMFT score was 28.00%; proportion of missing components of DMFT score, 1.43%; proportion of filled components of DMFT score, 70.57%. The proportion of filled components of DMFT score among disabled persons of all age group in Ulsan were evaluated to be a similar level to non-disabled citizens in Ulsan from 2010 Korean National Survey. The oral health care programs for disabled persons by voluntary services of dental professionals and other civilians are evaluated to be effective for the oral health promotion of disabled persons in Ulsan.

Objectives: The purpose of the study is to investigate the relationship between oral health status and body mass index (BMI) in adults over 65 years old. Methods: The study subjects were 4,550 adults over 65 years old from the 5th Korea National Health and Nutrition Examination Survey(KNHANES V) in 2010-2012. Mastication-related oral health status included the number of remaining teeth, and mean number of decayed, missing, and filled permanent teeth(DMFT). Body mass index(BMI, $kg/m^2$) was categorized as underweight(<18.5), normal weight (18.5-22.9), overweight(23.0-24.9), and obese(${\geq}25.0$). Multinomial logistic regression analysis was performed to examine the association of BMI categories with the number of remaining teeth and DMFT. Results: The mean number of DMFT was highest($13.0{\pm}0.7$) in the underweight group and lowest($8.8{\pm}0.3$) in the obese group. Those having less favorable masticatory ability, and fewer number of remaining teeth and no prosthesis, tended to be underweight. Those having a higher number of remaining teeth and prosthetic teeth tended to be overweight or obese. In the multinomial logistic regression analysis, compared with those having 20 or more remaining teeth, including prosthetic teeth, those having less than 20 remaining teeth and no prosthesis had 4.48 times higher odds ratio of being underweight. DMFT was positively associated with underweight, while negatively associated with overweight or obesity. Conclusions: The masticatory ability and dental caries prevention maintained the healthy body weight in adults of old age.
