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).

영구치 우식발생에 작용하는 다양한 요인들의 예측기간에 따른 예측인자로서의 타당성과 안정성을 평가하기 위하여, 부산광역시 D 초등학교 1학년 남녀 학생 249명을 대상으로 연구 1차년도에는 3년간 추적 조사할 우식발생 관련 요인의 확인을 위하여 대상자의 유구치 우식상태, 구강건강관리행위, 인구통계학적 변수, 타액과 구내미생물의 특성에 대하여 조사하였고, 연구 2-4차년도에는 각각 대상자의 1-3년간 영구치 우식발생 여부를 조사하여 다음과 같은 결론을 얻었다. 1. 1년간 영구치 우식발생은 Dentocult LB 판정결과가 2도 이상인 학생이 1도 이하인 학생에 비하여 2.3배 높았다. 2. 2년간 영구치 우식발생은 우식경험유구치면수가 0개인 학생에 비하여 1-10개인 학생이 5.2배, 11개 이상인 학생이 6.3배 높았다. 3. 2년간 영구치 우식발생은 Dentocult LB 판정결과가 2도 이상인 학생이 1도 이하인 학생에 비하여 2.3배 높았다(p=0.036). 4. 3년간 영구치 우식발생은 우식경험유구치면수가 0개인 학생에 비하여 1-10개인 학생이 3.9배, 11개 이상인 학생이 8.5배 높았다.

The aim of this study was to evaluate the competency of the Easyperio test, a genetic test method based on real time PCR for the detection of bacteria that cause dental caries and periodontal disease. To verify the validity of this text, various dental health evaluations were administered to 33 boys between the ages of 12 to 14, as this age group commonly experiences dental caries. These evaluations included a dental caries experience survey, a first molar health evaluation, the Dentocult Streptococcus mutans (SM) strip mutans, the Dentocult Lactobacillus spp (LB) test, and the Easyperio test. The correlation coefficients between the level of the Dentocult SM strip mutans and the dental caries experience were DT (R=0.570, p=0.001), DMFT (R=0.376, p=0.031), and first molar health (R=-0.395, p=0.023). The correlation coefficients between the amount of SM in the Easyperio test and dental caries experience were DT (R=0.528, p=0.002), DMFT (R=0.369, p=0.035), and first molar health (R=-0.426, p=0.013). The correlation coefficients between the level of the dentocult SM strip mutans and the SM amounts of the Easyperio test were S.mi (R=0.564 p=0.001) and S.mu (R=0.621, p=0.002). The correlation coefficients between the level of the Dentocult LB test and the SM amount of Easyperio test was S.mi (R=0.495, p=0.003). In conclusion, Easyperio test may be an easy and effective method for the differentiation and diagnosis of dental caries through quantitative and qualitative analysis of oral bacteria.

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.

Objectives : Prunus mume has been used for the folk medicine from old times. The purpose of the study was to investigate the antimicrobial activity of prunus mume extract to various oral microbes. Methods : This study was carried out to examine the antimicrobial effect of Prunus mume extract against oral microbes. Data were collected using a Dentocult SM Strip mutans and Dentocult LB Strip mutans from April 5 to May 4, 2013. A total of 36 experimental and 32 control group were selected for this study. Results : The MIC of Prunus mume extract was tested for 0.39% in S. mutans, S. salivarius and S. auerus, 0.78% in S. mitis, S. equi and E. coli. In vivo, experimental group showed significantly the lower Streptococcus mutans levels by the use of the gum contained Prunus mume extract from 15 days compared with control group(p=0.012). The reduction was more significant in Lactobacilli level of the experimental group than the control group(p=0.022). Conclusions : These findings suggest that the oral products containing Prunus mume extracts is effective in preventing oral diseases.
