  • The purpose of this study was to examine the relationship between the Dentocult SM and LB scores of students and their DMF rate. The subjects in this study were 134 special school students in south Gyeong-sang province. After they were tested to find out their, they received tooth brushing education and preventive treatment. The test, education and treatment were all conducted from March 17 to April 9, 2008. Their oral state was checked and recorded by using a mirror and explorer, and then the data on oral state were analyzed to their DMFT, DT, FT and MT rates. All the collected data were analyzed with SPSS 15.0 for Windows program, and independent-samples t-test, one-way ANOVA and crosstabs analysis were implemented to see what differences their disability type, gender, Dentocult-SM scores and Dentocult-LB scores made. The findings of the study were as follows: 1. As for connections between disability type and DMFT rate, the students with mental retardation were similar to the other students in that regard. The mentally retarded students had higher DT and FT rates than the other students, and the MT rate of the latter was higher than that of the former. 2. Concerning the relationship of gender to DMFT and DT rates, the girls had larger DMFT and DT rates than the boys, and the FT and MT rates of the boys were higher than those of the girls. 3. As to links between Dentocult SM scores on the tongue and DMFT, the students whose bacteria was mildly activated had the highest DMFT rate, and the students who had a severely activated bacteria had the highest DT and FT rates. Those who had a moderately activated bacteria had the highest MT rate. 4.Regarding the connection of Dentocult SM scores on maxillyright molar to DMFT and DT rates, the students whose bacteria was severely activated had the highest DMFT and DT rates. Those who had no activated bacteria had the largest FT rate, and the students who had a mildly activated bacteria had the highest MT rate. 5.Regarding the connection of Dentocult SM scores on maxillyleft molar to DMFT and DT rates, the students whose bacteria was severely activated had the highest DMFT and DT rates. Those who had no activated bacteria had the largest FT rate, and the students who had a mildly activated bacteria had the largest MT rate. 6. Regarding the connection of Dentocult SM scores on mandibularright molar to DMFT and DT, FT rates, the students whose bacteria was severely activated had the highest DMFT and DT, FT rates. Those who had a moderately activated bacteria had the highest MT rate. 7. Regarding the connection of Dentocult SM scores on mandibularleft molar to DMFT and DT rates, the students whose bacteria was mildly activated had the highest DMFT and DT rates. Those who had no activated bacteria had the largest FT rate, and the students who had a moderately activated bacteria had the highest MT rate. 8. Regarding the connection of Dentocult LB scores to DMFT and DT rates, the students whose bacteria was severely activated had the highest DMFT and DT rates. Those who had no activated bacteria had a moderately FT rate, the students who had a mildly activated bacteria had a mildly MT rate.

  • Mobile oral exam at the facilities for the disabled in Seoul is to improve the oral health of the disabled who can hardly approach dental clinic. We analyzed 1609 oral exam records at 24 facilities (11 special-education schools, 10 living facilities, 2 mental hospitals, 1 health care facility for the elderly) in 2011. The purpose of this study is to figure out the oral health state of the disabled in facilities in Seoul and to compare with the non-disabled in National Survey 2010 and 2008. 1. Special-education school : DMFT index of age 15 is 5.4 which is higher than 3.6 (DMFT index of age 15) of National Survey in 2010. 2. Living facility : DMFT index of ages 35~44 is 8.4 which is higher than 5.2 (DMFT index of ages 35 ~44) of National Survey in 2008. DT rate is higher (31.3% vs 19.2%) and MT rate is lower (7.6% vs 15.5%). 3. Mental hospital : DMFT index of ages 35~44 is 11.3 which is higher than 5.2 (DMFT indext of age 35~44) of National Survey in 2008. DT rate is significantly higher (50.7% vs 19.2%) and FT rate is lower (35.1% vs 65.3%). 4. Health care facility for the elderly : DMFT index of ages 65~74 is 7.1 which is slightly lower than 8.7 (DMFT index of ages 65~74) of National Survey in 2008. The number of existing natural teeth is similar (16 vs 18).

  • This study was implemented for 84 students of dental hygiene to show the correlation between dental caries experience and improved caries activity test. Dental caries experience for the sample groups was examined and stimulative saliva secreted for 5 minutes was collected into the tube to check saliva secretion rate. Dentocult LB test was executed to observe Lactobacilli colonies after 96 hour cultivation of culture slides moistened with stimulative saliva. Dentocult SM test(screening strip, site strip) was done to measure SM colonies distribution after 48 hour cultivation of culture strips applied with collected saliva and dental plaque respectively, and salivary buffering capacity was checked by means of Dentobuff strip kit. Following conclusions are obtained after examining the relation between Dentocult LB, Dentocult SM, Dentobuff strip test results and DMFT index, salivary secretion rate. 1. Showed no significant difference between Dentocult LB test results and DMFT index, salivary secretion rate. 2. Showed no significant difference between Dentocult SM(screening strip) test results and DMFT index, salivary secretion rate. 3. Showed significant difference between Dentocult SM(site strip) test results and DMFT index(pE0.05), but showed no significant difference between Dentocult SM(site strip) test results and salivary secretion rate. 4. Showed no significant difference between Dentobuff strip test results and DMFT index, but showed a very wide difference between Dentobuff strip test results and salivary secretion rate(pE0.01).

  • 연구목적: 이 연구는 지역사회 치면열구전색 사업의 치아우식 예방효과를 평가하고자 시행되었다. 연구방법: 연구 대상자는 2005년부터 2008년까지 김천시에 소재한 34개 초등학교에 재학 중인 9,001명 중 2005년 최초 구강검사 당시 상·하악 제1대구치에 치아우식이 없는 치아와 학생 4,768명을 최종 대상자로 선정하였다. 2005년도에 치면열구전색을 실시한 1,478명에 대해 3년간 추적조사가 이루어졌고, 2006년에 치면열구전색을 실시한 999명에 대해 2년간 추적조사를 하였으며, 2007년에 치면열구전색을 실시한 458명에 대해 1년간 추적조사 후 기술통계 및 교차분석을 시행하였다. 연구결과: 치면열구전색 실시군의 DMFT rate는 1년 추적 후 1.4%에서 3년 추적 후 4.1%, DMFT index는 1년 추적 후 0.18개에서 3년 추적 후 0.70개로 추적기간이 길어질수록 높게 나타났다. 1일 평균 칫솔질 횟수는 DMFT rate와 DMFT index에 영향을 미쳤다. 즉 치면열구전색을 실시한 대상자라도 1일 평균 칫솔질 횟수가 적으면 DMFT rate와 DMFT index는 높게 나타났다. 결론: 치면열구전색을 실시한 대상자에서도 올바른 칫솔질에 대한 구강보건교육이 선행되어야 한다.
