School dental clinic programs is the most active and effective programs to prevent the oral disease for school-children and it is one of the recommended programs by the advanced and welfare countries. In Korea, 15 primary schools have been established the school dental clinics in 1999 as one of the public oral health programs supported by the Ministry of Health and Welfares, and expanded more every year. 11 school dental clinics among 15 were participated for 2-years evaluation project. Such items as the structure, the process, the supply of dental services, the promotion of the health level and the community supports were evaluated through the standardization by governmental suggestions. Average score for 2-years evaluation was estimated as 81.35% as considerably good remark. In detail, score 4.74 for the structure, 22.10 for the process, 19.77 for supply of dental services, 26.22 for promotion of the oral health level and 8.53 for the community supports were calculated. In conclusion, school dental clinic programs in Korea were evaluated considerably good and they should be extended to all primary schools as possible.

The purpose of this study was to obtain database for developing a model of incremental dental care system in Korea. The author conducted the incremental dental care for 232 persons during one year in personal dental hospital. The data was analyzed improvement of oral health conditions during initial stage and 1st incremental care stage, and required cost during one year. The results were as follows ; 1. Active caries free rate was increased from 75.43% to 94.83% during incremental dental care. 2. The mean care time was estimated 486.1 minutes per one person. The dental chair-time for incremental dental care was 314.9 minutes and the indirect required time was 171.2 minutes. 3. The mean care cost of incremental dental care was estimated 413,159 Won based on customary fee and 284,576 Won based on relative value scale, 278,521 Won based on labor cost and clinic operating cost. 4. The proper incremental dental care cost of the first year until highschool student was estimated about 280,000 Won, and the cost seemed to be reduced from second year. 5. It is suggested that incremental dental care program in personal dental clinic is effective means of improving oral health and it is recommended to extend the incremental dental care program.

The purpose of this study is to estimate the preventive effect for dental caries by 3 years water fluoridation of Ok-cheon county in Korea, and to examine the dental fluorosis and other systemic diseases. Dental and medical surrey had been done for 223 children from the year 1997 to 2000, for 6-year old, 9year old and 11-year old children at Ok-cheon County. The obtained results were collected and compared with the control group. The obtained results were as follows. 1. Dental caries were reduced at the 27% on DMFT index and 14% on DMFS index in children of age 11 for 3 years. 2. There is neither evidence for the increase of dental fluorosis rate nor the physical specification syndromes at the On-cheon County children for 3 years. 3. We need more water fluoridation periods for expecting more fluoridation effect.

Detect of initial caries is important to get the preventive or treatment planning. Dentists used to examine the teeth with their naked eyes and sometimes it causes to make the faults for preventive caries of sealants. Now a days, DIAGNOdent(KaVo Co) was deviced to determine the early caries lesion by use of soft laser beam and it make easy to decide to care either sealing or filling. The study was devided two steps as laboratory experiment and clinical study. In laboratory initial caries lesion were selected and determined the caries levels as no caries, initial caries enamel or advanced caries for dentine, and preventive planning as no cares, sealing, sealing with filling or filling, by naked eyes, intraoral X-ray taking, and by use of DIAGNOdent device. The results were compared with the results of examined samples of longitudinal section of the deepest pit each tooth. In addition, 50 posterior teeth with no caries or initial caries for 10 volunteers were examined by 10 dentists and determined by DIAGNOdent, in order to make caries decision and preventive plans for each teeth. The data were collected and compared each other, and fined considerable differances by each checking methods, DIAGNOdent offers the highest degree of sensitivity. From visual inspection carried out by a group of general practitioners, the correct diagnosis of fissure caries was achieved in only 68% of all caries, but over 70% when using the DIAGNOdent. In this study the DIAGNOdent numerical data indicates no caries lesions in the enamel show values of between 0 and 15, and initial lesion in the enamel show values of between 16 and 70, and that values of beyond that indicate dentine caries.

권혁주,서현석,신승철 대한구강보건학회 2001 大韓口腔保健學會誌 Vol.25 No.1

The author had performed the physico-chemical experiments and clinical evaluation for the newly developed dentifrice contained with such ingredients as zeolite of salt granule and sodium metaphosphate, in order to increase the plaque removal effect on the interdental area and the stain removal effect and to inhibit the calculus formation. The study evaluated the physico-chemical experiments of zeolite for the plaque adsorption effect, the granule breakage test, the cleaning effect of interdental area and the stain removal effect and the clinical evaluation participated by 90 young adults volunteers who provided a consent for their participation. The obtained results were follows 1. The plaque adsorption capacity of zeolite was highly effective than any other abrasives like DCPD(dicalcium phosphate, dihydrate) and calcium carbonate. DCPD was more effective than calcium carbonate. 2. The dentifrice containing sodium metaphosphate and zeolite was effective in the cleaning of interdental area. 3. The granulated zeolite was broken with the 200-300g/㎠ of manual toothbrushing power. 4. The result of stain removal test using hydroxyapatite disc was significant difference between the dentifrice containing sodium metaphosphate and zeolite and the control by 10, 27 at the ΔL value(p<0.05). 5. In clinically, the dentifrice containing sodium metaphosphate and zeolite was highly effective in the plaque removal effect among three dentifrice and the dentifrice containing sodium metaphosphate was more effect than the control(p(0.05). 6. The dentifrice containing sodium metaphosphate and zeolite was clinically effective in the initial inhibition of calculus formation(p<0.1).
