The aim of this research was to analyze the differences for the oral health status of the elderly people living in the long-term care facilities and the non-resident elderly. The study was conducted on 469 elderly people of the same age, gender and basic living conditions. Elderly residing in long-term care facilities had higher dental caries prevalence(p=0.019), DT(p=0.001), and MT(p=0.047) than non-resident elderly, and had lower FT(p<0.001) than non-resident elderly. The elderly living in facilities were 1.93 times more likely to be caries than non-residents, and 0.73 times more likely to have a filled tooth. The probability of denture use was 0.15 times for the maxillary and 0.13 times for the mandibular. The probability of denture needs was 5.61 times for the maxillary and 5.65 times for the mandibular. All of these results showed significant differences. As a result of this, it can be used as basic data for establishing oral health policy for oral health promotion of the elderly living in Long-term care facilities.

Purpose: This study aimed to evaluate the anatomic circle around the impacted lower third molar to show, document, and correlate essential findings that should be included in the routine radiographic assessment protocol as clinically meaningful factors in overall case evaluation and treatment planning. Materials and Methods: Cone-beam computed tomographic images of impacted lower third molars were selected according to specific inclusion criteria. Impacted teeth were classified according to their position before assessment. The adjacent second molars were assessed for distal caries, distal bone loss, and root resorption. The fourth finding was the presence of a retromolar canal distal to the impaction. Communication with the dentist responsible for each case was done to determine whether these findings were detected or undetected by them before communication. Results: Statistically significant correlations were found between impaction position, distal bone loss, and detected distal caries associated with the adjacent second molar. The greatest percentage of undetected findings was found in the evaluation of distal bone status, followed by missed detection of the retromolar canal. Conclusion: The radiographic assessment protocol for impacted third molars should consider a step-by-step evaluation for second molars, and clinicians should be aware of the high prevalence of second molar affection in horizontal and mesioangular impactions. They also should search for the retromolar canal due to its associated clinical considerations.
Objectives: The purpose of the study was to identify the relationship between metabolic syndrome and oral diseases in the middle aged and elderly in Korea. Methods: The study subjects were 6,390 people over 40 years old from 2010 and 2012 Korea National Health and Nutrition Examination Survey. The survey questionnaire consisted of health, nutrition, and oral examination surveys. The independent variables included general characteristics, health behavior, oral health behavior, and metabolic syndrome. The dependent variables included dental caries experience and periodontal disease. The oral examination was carried out by the dentist based on World Health Organization standard. Results: The average prevalence rate of metabolic syndrome MS was 23.79%, including 54.84% of risk group and 21.37% of normal group. The missing teeth rate was 82.38%, DMFT rate was 90.28% and the periodontal disease rate was 33.15%. Those having abnormal fasting blood glucose had 1.17 fold(95% CI: 1.00~1.37) higher periodontal disease than the normal group. The abnormal HDL cholesterol group had 1.25 times higher odds ratio(95% CI: 1.07~1.46) and the obese group had 1.27 times higher odds ratio(95% CI: 1.07~1.51). The risk group had 1.20 times higher odds ration(95% CI: 1.00~1.44) and that of the metabolic syndrome group was 1.60 times higher(95% CI: 1.29~1.97) in periodontal disease. The high blood pressure group had 1.25 times of missing teeth prevalence rate(95% CI: 1.00~1.37). The metabolic syndrome group had 1.47 times of missing teeth prevalence rate(95% CI: 1.11~1.94). Conclusions: The middle aged and elderly people in Korea had higher rate of metabolic syndrome and oral disease. It is necessary to implement the preventive oral health examination for the control of metabolic syndrome and oral diseases prevalence.

Purpose: The purpose of this retrospective study was to investigate the relationships of types of dental insurance coverage in Korea with sociodemographic characteristics and the prevalence of systemic and oral diseases, as well as to evaluate the socioeconomic impact of Korean dental insurance policies. Methods: Sample cohort data from 2006 to 2015 were obtained from the National Health Insurance Service. Patients were divided into 2 groups. The exposed group comprised patients who received insurance benefits for complete dentures, removable partial dentures, and implant care, while the control group comprised patients who did not receive these benefits. The type of insurance coverage and the prevalence of systemic and oral diseases were compared between the 2 groups. Results: Patients who received benefits in the form of complete dentures, removable partial dentures, and implants had similar sociodemographic characteristics in terms of sex, age, income quintile, and type of insurance coverage to the control group. The prevalence of hypertension, anemia, renal disease, rheumatoid arthritis, osteoporosis, asthma, and cerebral infarction was higher in the exposed group than in the control group (P<0.05). The prevalence of periodontal diseases and dental caries was also higher in the exposed group. Conclusions: Korean dental health insurance policy has been beneficial for the medical expenses of low-income and elderly people suffering from a cost burden due to systemic diseases. However, since there is a tendency to avoid invasive interventions in older patients due to the high risk of systemic diseases, insurance coverage of dentures may be more helpful from a socioeconomic perspective than coverage of dental implant treatments.

Objectives: The aim of this study was to investigate the effect of water fluoridation program(WFP) on dental caries prevention in Ulsan, Korea. Methods: The data of control group were extracted from 2012 Korean National Oral Health Survey(KNOHS). Since 1998, WFP was implemented in Ulsan. The subjects were 670 subjects including 10 to 12-years old children in 2009. The control subjects were 4,871 people in non-fluoridated metropolitan cities comparable to Ulsan. The control subjects were selected from 2012 KNOHS. A self-reported questionnaire was completed by the variables including oral health behaviors on daily frequency of toothbrushing, eating snacks and beverages. Oral health examination was carried out by two dentists who received a training in KNOHS with an inter-examiner-agreement. Caries preventive fraction was calculated by the difference of DMFT and DMFS index. The preventive effects of the WFP program were focused on gender, number of fissure sealed teeth, daily frequency of toothbrushing, eating snacks and beverages. Data were analyzed using SPSS $19.0^{(R)}$(SPSS Inc., Chicago, IL, USA) statistical package. Results: DMFT indices of 12-year-old subjects(n=670) in WFP and control population(n=4,871) were 2.11 and 1.23, respectively with an estimated prevention effect of 41.7%. Conclusions: WFP in Ulsan reduced the prevalence of dental caries. WFP should be recommended for the public oral health program in other metropolitan cities.
Objectives: The aim of this study is to analyze the differences in factors related to the incidence of dental caries between children in fluoridated and non-fluoridated areas and compared the DMFT and DMFS scores to confirm the effect of water fluoridation program (WFP) in Geoje and Changwon. Methods: The oral health examination and questionnaire survey were conducted in fluoridated and non-fluoridated areas. The number of surveyed children aged 8, 10, and 12 years in the fluoridated and non-fluoridated area of two cities was 1,524 and 1,383, respectively. Self-recorded questionnaires included self-perception of their own dental health, daily toothbrushing frequency, intake frequency of cariogenic sweet snacks and beverages, experience of gingival bleeding, experience of unmet dental treatment, and use of oral hygiene device except for toothbrush and toothpaste. The prevalence of caries and fissure-sealant status were surveyed. The logistic regression analysis was used to analyze the difference in children's self-rated oral health status between the fluoridated and non-fluoridated area. The mean number of sealed teeth and surfaces, marginal means of the DMFT and DMFS scores adjusted for the difference in the samples' sex distribution, and region were compared between the fluoridated and non-fluoridated areas. Results: In the fluoridated area, the experience rate of unmet dental treatments was higher among children aged 10 years, intake frequency of cariogenic sweet snacks and beverages were higher among the whole sample, and experience rate of professional fluoride application were lower than in the non-fluoridated area. The DMFT score for permanent dentition adjusted for differences in sex, region, and mean number of fissure-sealed teeth in the fluoridated area was significantly lower among whole samples and 8-, 10-, and 12-year-olds alone than in the non-fluoridated area. Conclusions: WFP can alleviate oral health inequality because it is effective in reducing the incidence of caries among children is disadvantaged demographic, socioeconomic, and cultural contexts.

The incidence and several characteristic features of fused and geminated teeth were studied radiographically, with full mouth periapical radiogram and pantomogram, in 4201 patients of mixed dentition and 5358 patients of permanent dentition. The obtained results were as follows: 1. The prevalence was revealed to 2.86%, 0.32%, 0.33%, and 0.06% in deciduous fused tooth, permanent fused tooth, deciduous geminated tooth and permanent geminated tooth respectively, and these anomalies were occured in female more than male. 2. Fused teeth were observed predominantly in lower anterior teeth area, especially in lateral incisor and canine region, and many cases of deciduous geminated tooth were observed in upper central incisor region. 3. Congenital missing rates of succedaneous tooth in deciduous fused teeth were 57.1 %, 85.7%, 71.0%, 69.0% in upper right and left central-lateral incisor regions, lower right and left lateral incisor-canine regions, respectively. 4. Prevalence of dental caries was 42.3%, 18.8% and 5.6% in deciduous fused, deciduous geminated and permanent fused tooth, respectively. 5. In classifying of fused and geminated teeth into 9 types, by following appearance such as number of crown, root, pulp chamber and pulp canal of those teeth, it was more favorable that Type Ⅰ(2 crown, 2 root, 2 pulp chamber, 2 pulp canal) in deciduous fused tooth and Type Ⅸ (I crown, 1 root, 1 pulp chamber, 1 pulp canal) in permanent fused tooth, deciduous and permanent geminated tooth.

The aim of this study was to evaluate the effect of a water fluoridation program (WFP) on prevention of dental caries in Gimhae City, Korea, with reference to the results of 2012 Korean National Oral Health Survey (KNOHS). In WFP population, 972 subjects including 8-, 10- and 12-year-old children in Gimhae City were examined in 2009. The WFP in Gimhae city has been implemented since 1999. 1872 subjects in non-fluoridated small and medium sized cities similar to Gimhae city were selected from 2012 KNOHS data as the control population. Two dentists who received training in KNOHS with an inter-examiner-agreement examined oral health status of all subjects. To assess the effects of WFP on dental caries, caries preventive fraction was estimated by assessing the differences of decayed, missing, and filled teeth (DMFT) index and decayed, missing, and filled surfaces (DMFS) index, DMFS in pit and fissures and smooth surfaces between WFP population and the control. Univariate analysis of variance adjusted for gender and number of fissure-sealed teeth or surfaces was conducted. DMFT of 12-year-old subjects (n=354) in WFP and control population (n=1,518) were 1.60 and 2.12, respectively, with an estimated prevention effect of 24.7%. Caries preventive fraction on pit and fissure, and smooth surfaces of WFP subjects was estimated 27.5% and 24.0%, among subjects aged 12 years, respectively. WFP in Gimhae City, Korea reduced the prevalence of dental caries and is recommended as a public oral health program where a fluoride-containing toothpastes are commonly used.
1,596 ‘H' primary school children were surveyed every year on their oral hygiene status from 1981 to 1984. The results were as followings. 1.dmft rate; 27.94%/ 28.32%/33.33%/28.98% 2.dmf index;2.51/2.90/3.21/2.93 3.dmf rate ;11.87%/11.44%/13.77%/11.26% 4.dmf index ;5.33/5.86/6.63/5.70 5.DMFT rate ;6.96%/5.00%/6.52%/6.34% 6.DMFT indes;1.07/0.67/0.90/0.86 7.DMFS rate ;2.03%/1.46%/1.98%/1.79% 8.DMFS index;1.57/0.98/1.36/1.22
