The purpose of this study was to collect basic data for the development of effective oral health education program in elementary school. The subjects in this study were 604 fourth-year, fifth-year and sixth-year students of an elementary school in Seoul. Oral health awareness and behaviors were surveyed and analyzed. The findings of this study were as follows: 1. The most common time for toothbrushing was after dinner(62.0%) and before bedtime(62.3%). By school year, the largest number who brushed their teeth after dinner were fourth and fifth graders while the greatest number who did so after breakfast were sixth graders Seventy-four percent of respondents brushed the teeth twice or more a day. By school year, the fifth-year students brushed their teeth the least while girls outperformed the boys in daily toothbrushing frequency(p<0.05). Regarding the intake of cariogenic food, 62.1% took that kind of food once or more a day. By school year, the fifth graders took the most (p<0.05), and girls took more cariogenic food than the boys(p<0.05). 2. Ninety percent of the respondents had visited a dental clinic. By grade, the sixth-year students had visited a dental clinic more frequently and girls more frequently than boys. Eighty percent of the respondents visited a dental clinic to receive treatment but just 12.3% visited a dental clinic to prevent oral diseases. Concerning the fetor of dental treatment only 14.4% expressed fear. School year made no difference, yet the percentage of girls who experienced fear was higher than that of boys(P<0.05). Regarding preventive treatment, 39.7% experienced pit and fissure sealing and 24.2% experienced the application of fluorides. All the students hadn't much experience in preventive treatment regardless of school year -- gender didn't make a difference. 3. Fourty-six percent of respondents had a preference for the fluoride mouth rinsing program; 38.4% wanted that grogram to continue. As to the reason for preference, 38.2% preferred it because of the prevention of dental caries, 43.0%, the largest percentage, didn't favor it because they found it too much trouble to do(some of the respondents gave two different answers). 4. Despite an increase in the frequency of toothbrushing at the right time, they still took cariogenic food frequently Their visit to a dental clinics also aimed at treatment more than at prevention, and they had very narrow experience of preventive treatment. Furthermore, the fluoride mouth rinsing program failed to draw their interest. Therefore, it is recommended that a successful real health education program should be developed.

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.

Hyock-Soo Moon,Sun-Chui Choi,Pill-Hoon Choung3 대한구순구개열학회 2001 대한구순구개열학회지 Vol.4 No.2

This study was performed to determine the prevalence of hypodontia and hyperdontia of permanent teeth among Korean schoolchildren, and to compare differences in the prevalence between Korea, other country, and other ethnic groups. The sample consisted of 346 girls aged 6.9~0.3 yr and 375 boys aged 6.8~0.4 yr on whom a panoramic radiograph was taken at Yeonchun-Gun community in Korea. The prevalence of congenitally missing teeth (third molars excluded) was 6.7% in boys and somewhat higher, 9.5% in girls, and 8.0% for both sexes combined. On the average, number of missing teeth per affected child was 1.9 teeth. The most commonly congenitally missing teeth were the mandibular second premolar (32.7%), followed by the mandibular incisor (28.7%), the maxillary second premolar (16.7%), and the maxillary lateral incisors (10.2%). The prevalence of supernumerary teeth was 2.1 % in boys, 1.4% in girls, and 1.8% for both sexes combined. The most common supernumerary teeth were the mesiodens (76.9%), followed by the supernumerary premolar (23.1%). The affected male-female ratio was 1.6: 1.0. The prevalence of congenital missing teeth in this study was similar to in studies of Japanese, Danish, American and German. The frequency of hyperdontia was lower in this study than in studies of Chinese children, Japanese and American.
