Background: Legal regulations and fees have been established in Korea to provide visiting oral health care services to individuals with long-term care insurance (LTCI). However, beneficiaries of this service are very limited. Therefore, to improve the Korean system we propose a comparative analysis with the Japanese system. Methods: This study is a descriptive analysis based on secondary data, such as statistics, laws, and service record forms from Korea and Japan. The most recent institutional documents were obtained through a Google search. The variables investigated were financial resources of LTCI, co-payment structure, monthly limit of LTCI benefits, care levels of LTCI, service providers, service costs, contents of service, and the number of cases of service. Results: In both Korea and Japan, LTCI is financed through a combination of taxes and insurance premiums. However, the monthly limit for receiving LTCI services in Japan is about 2.4 times higher than in Korea. Visiting medical and dental treatment is also possible in Japan. Furthermore, nursing staff can provide daily oral health care services according to dental hygienists' instruction unlike Korea. Oral health care services in Korea are focused on oral hygiene and prevention of oral diseases, while Japan additionally provides oral function screening, patient education for oral health management, and training for nursing staff to enhance oral function, eating, and swallowing of the patients. Conclusion: We concluded that the possibility of visiting dental treatment, differences in monthly limit of LTCI benefits, oral function assessment and guidance, as well as collaboration with other healthcare professionals contributed to the difference in the frequency of utilization of visiting oral health care services between Korea and Japan.

Dental caries and periodontal disease are considered to be chronic, but can be prevented through an incremental oral health program covering all ages. The National Oral Health Program for adults provides oral health exam and scaling, and is covered by national health insurance for those over 20 years of age in Korea. The aim of this study was to collect basic data for developing an oral health program for adults by identifying factors related to awareness and need. The data were obtained by convenience sampling of 303 subjects. The use of dental plaque disclosing agents affected tooth brushing frequency, toothbrushing time and use of oral auxiliary devices. Education on toothbrushing methods affected toothbrushing time and use of oral auxiliary devices. Of those surveyed, 93.1% replied that an incremental oral health program for adults was needed, and 68.0% intended to participate. In a regression model, the factors that had an effect on the perceived need for an oral health program were education level, use of oral hygiene auxiliary devices, and toothbrushing time, and the factors affecting intent to participate were education for prevention of periodontal disease and the use of oral hygiene auxiliary devices. The subjects stated that the following oral health programs were needed: an oral bacteria exam (74.3%), toothbrushing education (71.6%), a bad breath exam (69.3%), education on use of oral hygiene auxiliary devices (46.9%), a dental plaque exam (42.9%) and a saliva exam (37.6%). Oral health education appears to be an important factor for participation in an incremental oral health program.

Background: Extrusion of debris is a major factor that results in postoperative pain during root canal treatment with various instruments and instrumentation techniques. Therefore, instrumentation techniques that extrude minimal debris into the periapical area while reducing pain are desirable. This study aimed to compare the incidence of postoperative pain and intake of analgesic medication (frequency and quantity) after endodontic treatment of mandibular posterior teeth using two single files and full-sequence continuous rotary systems with different kinematic motions. Methods: Thirty-five of 105 patients were assigned equally to three groups according to the instrumentation system used: ProTaper Next (PN) X2, 25/06 (Dentsply, Maillefer, Ballaigues, Switzerland), One Shape (OS), #0.25/06 (Micro Mega, Besancon, France), and Wave One Gold (WG), Red - #0.25, 0.07 (Dentsply, Maillefer, Ballaigues, Switzerland). Five specialists were included in this study design; each professional prepared 21 teeth, and randomly selected 7 per instrument system. The VAS sheet ranging from 0 to 10 was used to record the initial and postoperative pains at 24, 48, and 72 h, and 7^th day after single visit endodontic treatment in mandibular premolars and molars with a diagnosis of asymptomatic irreversible pulpitis with or without apical periodontitis. Postoperatively, an analgesic, ibuprofen 400 mg was administered for intolerable pain at a dose of 1 tablet for 6 h. The patients were asked over the telephone regarding postoperative pain at intervals of 24, 48, and 72 h, and 7^th day using a visual analogue scale. Result: There were no statistically significant differences among the PN, OS, and WG systems (P > 0.05) with regard to the incidence of postoperative pain at any of the four time points assessed. Conclusion: The intensity of postoperative pain, frequency, and analgesic intake were similar across all three types of instrument systems; however, the reciprocating single file (WG) was associated with less postoperative pain than the full sequence continuous rotary file.

The purpose of this study was to investigate the relationship between oral cancer and such factors as smoking and drinking pattern, oral health status, dietary intake pattern, socio-economic status. Oral cancer patients and other disease patients who visited Yonsei University Dental Hospital from May to September in 2000 were selected as the study subjects. The numbers of cases and controls were 41, 108, respectively. Two groups were matched with age and sex for case control study. Oral examination and questionnaires survey was performed by the dentist. To assess the strength of associations between oral cancer and other variables, chisquare tests were performed. The results were as follows : 1. The durations of smoking and alcohol drinking were not related significantly with oral cancer. But the doses of smoking and alcohol intake increased the risk of oral cancer significantly(OR=2.52, 4.11, p<0.05). 2. Denture wearing, the number of missing teeth and spicy and salty food, coffee, tea and fresh fruit intake frequency did not significantly increase the risk of oral cancer. But low education level, residency in rural area increased risk of oral cancer significantly(p<0.01).

Objectives: The purpose of the study is to investigate the cognition of dental caries prevention by the level of socioeconomic status based on Gallup survey in Korea. Methods: This study was done by Korean Gallup survey in October, 2010. A trained researcher carried out the computer aided telephone interview(CATI) using a structured questionnaire. This study was based on the latest population statistics of resident registration and whole country's phone data base. This survey included 869 selected Korean adults over 19 years old, and they were asked to answer a CATI. The questionnaire consisted of general characteristics of the subjects and socioeconomic factors including age, gender, education level, monthly income, and residential area. Cognition of dental caries prevention was measured by Likert 4 scale including 'much', 'a little', 'rarely', and 'never'. The attitude toward dental caries prevention consisted of daily tooth brushing frequency, experience of oral health education, regular dental checkup, chewing gums(xylitol), regular scaling, and use of oral care devices. Data were analyzed using SPSS 20.0 for frequency analysis, t-test, chi-square test, and one way ANOVA. Cronbach's alpha was 0.462 in oral health concern and attitude. Results: Mean of the frequencies of daily tooth brushing in men was 2.54 times and 2.78 in women. By the comparison to age group, 35-44 years old group had 2.82 times, 19-37 years old group had 2.72 times, and 45-64 years old group had 2.51 times. The level of education and monthly income was proportional to the tooth brushing frequency. Highly educated and higher monthly income group received regular dental checkup within a year and used the auxiliary oral health care devices. Conclusions: This study suggested the relationship between dental caries prevention and socioeconomic status. It is important to provide the low socioeconomic group with the better oral health promotion services in the future.
