최은미,백대일,김종배 경복대학 2002 京福論叢 Vol.6 No.-

In an individual, four first molars are the most important ones of twenty deciduous teeth and thirty two permanent teeth. Therefore, all dentists and dental hygienists emphasize in each country that the life of them should be prolonged as long as possible. Besides, the first molars are called six years molars, because those are erupted at the age of six. Moreover, because Korean people say six years molar as youk-se koo-chi and June 9th as youk-wol koo-il in Korean, Korean dentists have presumed that youk-se koo-chi can efficiently be emphasized on youk-wol koo-il in each year. In connection with this reason, every June 9th has been designated as a day for educating Korean people in six years molar cares by Korean Dental Association since 1946. As a result, Korean dentists and dental hygienists have emphasized on June 9th each year that the life of six years molars should be prolonged as long as possible and educated Korean people in six years molar cares by the various educational methods during a week, which follows June 9th each year and is called Dental Health Week in Korea. In the result, the various dental health educational activities on June 9th and during Dental Health Week each year have been called a 6ㆍ9 event in Korea for more than 50 years. Nevertheless, the effectiveness of the 6ㆍ9 events has not been evaluated till now. For the purpose of confirming the effectiveness of the 6ㆍ9 events implemented for more than 50 years and selecting the contents of the more effective six years molar care education, the knowledges of six years molar cares had been surveyed in the freshmem of the educational course by questionnaire. The authors analyzed the freshmen's awarenesses of six years molars, period using six years molars, causative diseases for extracting six years molars, programs for preventing dental caries, programs for preventing periodontal disease, programs for treating dental and periodontal diseases at the early stages and necessities for dental and periodontal diseases to be prevented and discussed. The obtained results were as follows: 1. The effectiveness of the 6ㆍ9 events implemented for more than 50 years was not reliable, because the level of knowledges of six years molar cares was not high in the fresh men the college educational course. Therefore, it was concluded that the 6ㆍ9 events should be corrected in it's contents and methods. 2 In the 6ㆍ9 events, the student should be taught that the first molar is the six years molar and il must be used for a whole life. 3. The student should also be taught in the 6ㆍ9 events that almost all the six years molars are extracted due to dental caries and periodontal disease. 4. It should be emphasized in the events that the dental and periodontal diseases must be prevented for prolonging the life of six years molar. 5. The student should be taught in the events that the communal water fluoridation programs and pit & fissure sealing programs must be developed for preventing dental caries and the school based toothbrushing drills for preventing periodontal disease. 6. It should also be emphasized in the events that the periodic incremental dental care programs should be developed for treating dental and periodontal diseases at the early stage for prolonging the life of six years molar.

The purpose of this study was to obtain data relating to the growth and developmental patterns of faces in Korean female students during two years after six years of age, which were necessary to design the models for estimating the growth and developmental patterns of faces. Since forty two cephalometric measurements representing lateral facial pattern were measured on the lateral radiograms of 210 six year old girls resding in yeon Cheon-Gun county, Kyungki-Do province in 1995, they were longitudinally measured each year until the year 1997. Accoriding to the profile classification criteria reported by Lee and Moon, the profile of 210 six year-old students were classified into seven profile groups. During the two years after six years of age since 1995, the changed forty two cephlometiic measurements representing the growth and development of lateral facial pattern were discussed respectively in the seven profile groups. The obtained conclusions were as follows: 1. Cd-Pog Cd-Gn Ar-LIE Ar-Id Go-LIE Go-LIE Go-Pog and Ba-Pog distances were continued to increase each year after six years of age in all female seven profile group(P<0.01). 2. UIE-UIA/Cd-Or UIE-UIA/PNS-ANS and UIA-UIE/N-A angles were continued to increase each year, but GoI-Me/UIA-UIE angles were continued to decrease each year after six years of age in all female seven profile groups(P<0.01). 3. Sixteen lateral facial pattern composing angle and twenty six lateral facial pattern composing distance had statistially significant differences among seven profile groups at each year. 4. The distance change of PNS-ANS and Sd-Id per 10㎜ per 2years per 10㎜ during 2years had statistically signficant differences among seven profile groups, unlike any other lateral facial pattern composing distance change per 10㎜ per 2years.

The purpose of this study was to assess relative tooth abrasivity and to measure effective fluoride concentration of dentifrices selling in Korea for help consumer's selection of suitable dentifrice. Assessment of the abrasion on tooth produced by different dentifrices were carried out on bovine teeth in the laboratory and tested by radioactive dentin abrasion method. And total soluble fluoride concentrations within the dentifrices was determined using fluoride ion selective electrode with standard curve obtained from standard solutions of known fluoride concentration. 10 dentifrice samples were stored at 49t for 15 weeks and the measurements were made for each dentifrice in 1 week, 2 weeks, 3 weeks, 13 weeks and 15 weeks and 11 dentifrice samples were stored at 40.6C for 3 weeks and the measurements were made for each dentifrice in 1 week and 3 weeks. Tooth abrasivity of selling dentifrices is suitable for toothbrushing but dentifrice which recommended for patient who have tooth abrasion or erosion was somewhat high abrasivity level. Effective fluoride concentrations of selling dentifrices were maintained generally optimal level. But some dentifrices contaning CaCO_(3), as abrasive were decreased as time elapsed. It was suggested that relative tooth abrasivity must be marked on package and fluoride level should be maintained acceptable level in dentifrices for consumer's selection of suitable dentifrice.
