Objectives: This study aimed to validate the moderating effect of oral health on the relationship between perceived health status and health-related quality of life in the elderly and to use this information as primary data to suggest oral health policies for the aged society. Methods: This study included 3,707 subjects aged over 65 years who answered all the variables used in the study model and completed the health questionnaire and screening survey based on the sixth Korea National Health and Nutrition Examination Survey. Baron & Kenny's linear regression analysis using SPSS 22.0 and SPSS Macro Version 3.1 programs was performed to confirm the moderating effect of the number of remaining natural teeth, chewing difficulty, and cardiovascular disease on the relationship between perceived health status and healthrelated quality of life in the elderly. Results: The number of remaining natural teeth, chewing difficulties, and cardiovascular diseases affected the perceived health status of the elderly. As the number of remaining natural teeth increased, the effect of perceived health status on the quality of life in the elderly was buffered. The effect of perceived health status on the quality of life increased with chewing difficulties and the number of cardiovascular diseases. In particular, it was confirmed that chewing difficulties, rather than the number of cardiovascular diseases. had a greater effect on the quality of life in the elderly. Conclusions: Oral health policies and projects are required to ensure oral rehabilitation with dentures and implants and restore chewing function to improve the quality of life of the elderly in Korea.

Purpose: This study was conducted to identify factors influencing fundus examination to prevent diabetic retinopathy in diabetes patients to provide basic data to improve screening rates of fundus examinations. Methods: Raw data from the 6th Korea National Health and Nutrition Examination Survey, which is a cross-sectional and nationally representative survey, were used in this study. The subjects of the study were 1,029 adult diabetes patients over the age of 19 years who had been diagnosed with diabetes. The demographic characteristics, diabetes and disease-related characteristics and health behavior characteristics according to the fundus examinations were analyzed by the chi-squared test and logistic regression analyses were used to examine the factors influencing fundus examination. Results: A total of 333 patients underwent fundus examination at a screening rate of 32.2%. We identified factors influencing fundus examination in patients with diabetes as level of education, type of diabetes care, period of diabetes, and smoking. Conclusion: A multiple approach is required to raise the low screening rate of fundus examination, including specialized education for low-education groups. Moreover, nursing intervention should focus on subjects who do not engage in insulin and oral hypoglycemic agents and with diabetes for a long period.

This study aimed to evaluate the effects of national dental screening for children in Korea in the aspects of prevention of dental caries, the number of treatments related to dental caries, and cost of dental care. The study used the national cohort data on children health screening provided by National Health Insurance Service, and analyzed 32,937 1st dental screening, 22,608 2nd dental screening, 13,708 3rd dental screening, and 241,043 cases from the dental care of 27,944 children born in year 2008 and 2009. The decayed-filled teeth index and decayed-filled person rate, calculated from the results of the 2nd and 3rd dental screening, decreased as the number of preceding dental screening increased. Glass ionomer and amalgam restoration, pulp treatment of primary teeth and extraction of primary canine and molar were shown to decrease as the number of examined dental screening increased, and the total cost of dental care covered by national health insurance also decreased as the number of dental screening increased. In conclusion, national dental screening for children is an efficient and economical oral health care method that prevents dental caries and lowers the possibility of dental caries related treatment, thereby reducing cost of dental care.

Purpose : To evaluate the efficacy of panoramic radiography by comparing the results of clinical examination with radiographic findings. Materials and Methods: We studied 190 patients (20 men and 170 women; mean age, 40 years; range, 22 to 68 years) who visited the health promotion center of Korea Medical Science Institute and were examined both clinically and by panoramic radiography. We compared results from both examinations. Treatment options by clinical examination were described as "no treatment indicated", "treatment of dental caries", "removal of calculus", "treatment of periodontal disease", "prothodontic treatment" and "extraction of the third molar". Findings taken from the panoramic radiography were: dental caries, periapical lesion, alveolar bone loss, calculus deposition, retained root, impaction of the third molar, disease of maxillary sinus, bony change of mandibular condyle, etc. Results: The prevalence of panoramic findings were: 37.9% of dental caries, 17.4% of periapical lesions, 44.7% of alveolar bone losses, 62.6% of calculi deposition, 7.9% of retained roots, 26.8% of third molar impactions, 6.3% of diseases of maxillary sinus, 2.1 % of bony changes of mandibular condlye and 35.8% of miscellaneous lesions. Abnormal conditions revealed by panoramic radiography which had not been discovered on clinical examination were: 24.2% of the patients had dental caries, 17.4% had periapical lesions, 7.4% had calculi deposition, 5.3% had retained roots, 15.3% had third molar impactions. The opposite cases were: 5.2% had dental caries, 12.6% had calculi deposition, and 9.5% had third molar impactions. Conclusion: The use of panoramic radiography as a supplement to the clinical examination might be a valuable screening technique.

This study aimed to investigate parents' and dentists' perceptions of the national oral health screening for infants and children (OHS), and evaluate the dentists' accuracy of analyzing the results of OHS. A questionnaire survey was conducted, face-to-face or online, for 90 parents of children who received OHS in the Department of Pediatric Dentistry at Yonsei University Dental Hospital and 100 dentists working at local clinic or university dental hospital from May to October 2021. Most parents and dentists were aware of the importance of OHS, and approximately 96.7% of parents were satisfied with OHS. The requirements of parents and dentists about OHS were different. The reasons for having difficulties in explaining parents after OHS and the opinions on appropriate period and number of OHS were disagreed between pediatric dentists and general dentists. Regardless of dentists' major, work experience, elapsed period after taking online education program, the accuracy of the examination result was low. In this study, various opinions of parents and dentists on OHS were collected. Efforts should be made to enhance the oral health of infants and children by considering the requirements of parents and dentists and improving the accuracy of examination results.

This study proposed a registered dentist model for the disabled based on consumer in-depth interview and supplier survey. This study proposed that dental clinics in the community take role as registered dentists for the disabled. Qualification screening and facility prerequisites are required to be selected as the registered dentists for the disabled and patients of the registered dentists were restricted to the disabled who can cooperate to dental treatment services with or without the aid of physical bondage. In order to encourage the participation in the program, subsidies for the registered dentists were necessary. Also, this study proposed financial supports for the medical expenses for patients at the same level as the current dental care center for the disabled. The registered dentist program for the disabled meets the needs of disabled consumers, such as accessibility of medical institutions, expertise of medical staff, and ongoing treatments with familiar medical staff. The registered dentist program for the disabled is expected to provide prevention and ongoing management for oral health promotion of disabled people and it also contribute to lower economic burden of oral health care of the disabled.

The purpose of this study was to analyze the screening rates and examination results of the national dental screening program for infants and children since its initiation. Data for this study were obtained from the annual health screening statistical yearbook of the National Health Insurance Service. The investigation focused on the screening rate according to year, age, and region, as well as examination results from 2008 to 2021. The study revealed a general increase in screening rates over the years, with a simultaneous decrease observed as the age of the subjects increased. Regional variations in screening rates were observed, with the highest and lowest rates in Sejong and Jeonbuk, respectively. Analysis of examination results revealed an increasing proportion of subjects requiring treatment as they aged. From 2008 to 2013, less than 15% of subjects aged 18 - 24 and 18 - 29 months required treatment, whereas over 30% required treatment in the remaining age groups. Between 2014 and 2021, the proportion of subjects in the 18 - 29 month age group requiring treatment remained under 15%, but it exceeded 40% in the other age groups. In conclusion, active participation in national dental screening for infants and children is crucial to improving oral health outcomes.

Background: Leukoplakia is an asymptomatic and potentially malignant change in the oral mucosa and high frequencies have been reported among smokers. The present study concerned the prevalence of tobacco use and leukoplakia and also associations between the two. Study design: This cross sectional survey was conducted amongst the Gond tribal population of Kundam Block, Jabalpur district, Madhya Pradesh state, Central India during 2007 to 2009. Screening for leukoplakia was conducted by a medical officer with two mouth mirrors. It is only based on visual inspection and oral pathology was not performed. A semi-structured questionnaire was used to collect information on socio-demographic and smoking habits. Prevalence of leukoplakia among users and non-users of tobacco was calculated in terms of percentages. Results: Of 1,552 individuals aged more than 12 years of age who were screened, 144 (9.3%) were found to have oral leukoplakia. The prevalence of leukoplakia was significantly elevated among tobacco users as compared to non-users (11% vs 2.5%; p<0.001). The percentage of leukoplakia was almost similar in both tobacco smokers and chewers (9% vs 11%; p=0.304). However, the percentage of leukoplakia was especially high among those chewers who also smoked tobacco (21.9%). Conclusions: The findings of the present study showed a positive effect of tobacco use and prevalence of leukoplakia. Also the prevalence was very high among Gond tribe, a marginalized population living in central India. There is a need for effective screening and treatment of leukoplakia in this area.

The most critical health effect of lead exposure is the neurodevelopmental effect to children caused by the increased blood lead level. Therefore, the endpoint of the risk assessment for lead-contaminated sites should be set at the blood lead level of children. In foreign countries, the risk assessment for lead-contaminated sites is conducted by estimating the increased blood lead level of children via oral intake and/or inhalation (United States Environmental Protection Agency, USEPA), or by comparing the estimated oral dose to the threshold oral dose of lead, which is derived from the permissible blood lead level of children (Dutch National Institute for Public Health and the Environment, RIVM). For the risk assessment, USEPA employs Integrated-Exposure-Uptake-Biokinetic (IEUBK) Model to check whether the estimated portion of children whose blood lead level exceeds 10 µg/dL, threshold blood lead level determined by USEPA, is higher than 5%, while Dutch RIVM compares the estimated oral dose of lead to the threshold oral dose (2.8 µg/kg-day), which is derived from the permissible blood lead level of children. In Korea, like The Netherlands, risk assessment for lead-contaminated sites is conducted by comparing the estimated oral dose to the threshold oral dose; however, because the threshold oral dose listed in Korean risk assessment guidance is an unidentified value, it is recommended to revise the existing threshold oral dose described in Korean risk assessment guidance. And, if significant lead exposure via inhalation is suspected, it is useful to employ IEUBK Model to derive the risk posed via multimedia exposure (i.e., both oral ingestion and inhalation).

Purpose: This study was conducted to survey children's health status and need of customized visiting health care services in one province. Methods: The participants in this study were 237 caregivers of infants and preschoolers. Data were collected at the participant's home or public health center. Results: Many of the children did not receive developmental screening tests or dental examinations. In the beneficiary group, the prenatal checkup rate and children's vaccination rate were lower, and caregivers had more health problems than the other groups. On the assessment of home safety, unsafe conditions were more frequently found in the beneficiary group. The caregivers in the beneficiary group showed lower child rearing confidence than the other groups, and wanted customized visiting health care services most in the areas of developmental screening, regular health check-up and counseling, nutritional supplementation, and oral health care. Conclusion: These results indicate that it is necessary for children and parents in poverty to be provided with professional home visiting interventions for the promotion of child health and prevention of developmental problems and diseases. These findings can be used for developing future customized visiting health care service programs for infants and children in this community area.
