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).

The dentist total work of RHRVS were estimated to develope of national dental health insurance fee schedule. Three hundred dentists were selected by systematic random sampling. Mailing questionary survey were carried out to investigate dentist total work of RBRVS. Response rate showed 58%. Descriptive and multiple regression analysis were peformed for analysis. The highest total work value was apicoectomy of central incisor and the lowest was radiograph reading of root apex. The highest time consuming treatment was endodontic treatment of maxillary second Molar and the lowest was radiographic reading of root apex. The highest tecnical and physical work value was apicoectomy of central incisor and the lowest was radiographic reading of root apex. The highest value of judgment and psychologic work was endodontic treatment of maxillary second Molar and the lowest was infiltration anesthesia of low incisor. The highest value of stress was endodontic treatment of maxillary second Molar and the lowest was infiltration anesthesia of low incisor. Dentist treatment career, number of patients, rate of non insurance treatment and age distribution of patient factor were significantly influenced to the dentist total work of RBRVS.

The objective of this study was to analize the change of dental caries prevalence in Korean children and adolescents from 1989 to 2000. National oral examination survey reports in 1989,1991,1995 and 2000 were collected for this purpose The major finding were summerized and the results were as follows : 1. The dft of 5-year-old children in creased from 1989 to 1995 and decreased slightly from 1995 to 2000 the dt decreased or remained constant and the ft increased. 2. The dt of 5-year-olds decreased constantly by 1991 in rural area but in urban area, it remained stable by 1991 and the ft increased in rural and urban area. 3. The DMFT of 12-year-old children increased from 1989 to 2000 the DT decreased of remanined constant and the FT increased, the MT remained below 0.05 4. The DT index of 12-year-olds decreased constantly by 1991 in rural area but in urban area, it remained stable by 1991 and FT index increased in rural and urban area 5. The percentage of caries free and caries experience have increased in rural and urban area. According to results the dft of 5-year-olds and the DMFT of 12-year-olds have increased specially among the component of dft and DMFT dt and DT decreased or remain stable while ft and FT increased constantly which means that the restorative index(ft/dft, FT/DMFT) increased also and the percentage of caries experience increased. Based on this study, preventive approach is more required to lower caries prevalence of korean childeren
