  • The purpose of this study was to evaluate the correlation between caries experience, Quantitative Light-Induced Fluorescence-Digital (QLF-D) redings and new caries activity test (Cariview) results in preschool children. Fifty-seven healthy kindergarten children (male 28, female 29) were participated this study. The calibrated dentist investigated the caries experience of children and new caries activity test. Cariview samples were incubated in the activated medium at $37^{\circ}C$ for 48 hours. All QLF-D taking and readings were performed by one experienced and trained operator under identical conditions in a dental unit chair located in a darkened room. Analysis range was limited to the maxillary and mandibular anterior teeth. QLF-D redings (white spot and dental plaque) were analysed using QLF system. The dft index had a relatively high correlation with the QLF-D redings (white spot: r=0.617, simple plaque score: r=0.500) (p<0.01). Also, there was significant correlation between dft index and the Cariview score (r=0.286) (p<0.05). However, the Cariview score had no significant correlation between dt index and ft index (p>0.05). QLF-D can be evaluated objectively the initial caries lesions and dental plaque correlated with caries experience. Therefore, QLF-D will be useful to the study of caries prediction.

  • The objective of this study was to examine whether there is an association of oral health conditions between mothers and their preschool children in Korea. A sample of 823 preschool children and their mothers were selected for this study from the database of the fourth Korean National Health and Nutrition examination Survey. Preschool children were defined as children aged 4, 5, and 6 years old. The subjects were clinically examined for the presence of caries lesions (dft index) and their mother was checked for the presence of dental caries (DMFT index) and periodontal status (CPI). The socio-demographic characteristics and mother's oral health behaviours were considered covariates in this study. Univariate and multivariate analysis was adapted to assess the association of oral health condition between mothers and their preschool children. In univariate analysis, there were significant differences between preschool children's dft index and their mother's age (p=0.005), dental treatment demand for the past one year (p=0.034), and DMFT index (p=0.016). In multivariate analysis, only mother's DMFT index was significantly associated with their children's dft index after adjusting for covariates. In conclusion, the mother's oral health was partly associated with their preschool children's oral health in Korea.

  • The purpose of this study was to examine association between oral health status and perceived general health symptom. We analyzed 14,231 subjects who participated in Korea National Health and Nutrition Examination Survey (2007~2009). All individuals were examined by a questionnaire about socioeconomic history, smoking and drinking habit, the frequency of daily tooth brushing, the presence of regular dental visit, and EuroQol-5D. Dental survey was conducted to find the decayed, missing, and filled teeth (DMFT) index and community periodontal index. Subjects with perceived problem with mobility had higher DMFT index (odds ratio, 1.18, p<0.001). Subjects with with perceived problem with pain/discomfort had higher DMFT index (odds ratio, 1.16, p<0.001). Self-rating general health symptom was not associated with periodontitis (p>0.05). Perceived general health was associated with DMFT index. It is recommendable that we can use the perceived general health to predict oral health status.

  • Molar Incisor Hypomineralization(MIH) have recently gained intensive research interests and various clinical trials. Most prevalence, etiology, treatment studies in MIH were carried out in the European countries, and data from the Korean were seldom. This study aimed to investigate the prevalence of MIH and the status of dental caries and treatment on the first permanent molars in primary school children. For this study, 1,344 primary school students in Busan and Ulsan cities were examined directly the permanent incisors and first molars. The results of the survey were as follows: 81 MIH cases were identified among 1,344 cases. The prevalence of MIH in this group of children was 6.0%. Children with MIH showed a significantly higher DMFT value for permanent teeth than children without MIH. The mean number of decayed, missed, and filled in 1st permanent molars(DMFT index) was 1.17. The rate of children with restoration on 1st permanent molar was 13.6% and the sequence of restoration materials was as follows : composite resin, amalgam, gold inlay.

  • Since it is favorable to include the incipient caries lesion in the diagnostic criteria in adolescence, this study had surveyed dental caries status of adolescents at ages of 13 and 16 by using WHO basic methods and ICDAS-II codes. In this study, mean DMFT index was 3.71, and mean DT index was 1.94. For both indices, the age 16 group showed higher values than the age 13 group. By groups of teeth, DMFT index and DT index exhibited highest to the lowest values in molar, premolar, and anterior teeth, respectively. 77.46% of total numbers of teeth were classified as code 0 in ICDAS-II. Compared to anterior teeth, numbers of decayed teeth were increased in posterior teeth. All caries lesions in anterior teeth and premolars were limited to enamel. ICDAS-II code is an useful method to detect the incipient caries lesion, allowing preventive control on caries management.

  • The purpose of this study was to investigate the correlation between food intake pattern body component bone mineral density(BMD) and dental caries experience of college women and we wanted to determine the correlation of these factors with dental caries experience. Research was conducted to offer basic data to develope a nutritional program for the future prevention from oral disease. The subjects in this study were 132 college women who participated in the food intake survey and who's body component and BMD was measured. The statistical analysis was done by using the SPSS 15.0 program. The results of this study were as follows; 1. The food intake pattern was not directly correlated with DMFT index. 2. The body component was not directly correlated with DMFT index. 3. The SOS, BQI was directly correlated with DMFT index(p<0.05). 4. T-score of BMD had the greatest influence on DMFT index(p<0.05). Above results indicated that bone mineral density are related with the incidence of dental caries experience and further research is necessary to develop a nutritional and health promotional program in order to prevent oral illness.

  • The purpose of this study is to evaluate oral health status, caries-inducing bacterial activity of the mental retardation students, and developing motivation method for improving oral hygiene management by clarifying the relationship between caries-inducing bacterial activity and oral health status of mental retardation students. Caries experience indices, caries susceptibility test, gingival health evaluation, and oral hygiene management and oral health survey were performed. Results were as follows : 1. The DMFT index of disabled students(12 years) was 2.07. 2. The gingival inflammation was occurred more frequently in older ages. 3. There also was a high positive correlation between caries incidences and the results of caries-inducing bacterial activity test especially in deciduous teeth. This result suggested that the Dentocult SM mutans test as a caries activity test is a reliable method for measuring the status of dental caries in mental retardation students. Because it would motivate the mental retardation students to care more actively for their oral hygiene if they learn how much dental caries-inducing bacteria are living in their mouth by observing the bacterial colony on the cultured test strip, it can become a possibly efficient educational tool for the mental retardation students.

  • The purpose of this study was to obtain the data for dental caries experience and occlusal pattern to utilize these data for motivating oral health promotion and activating oral health care programme in preschool children of multicultural family. Caries prevalence on primary teeth was surveyed for 3-5 years old 190 children of multicultural families in Chonbuk province. The results were as follows : 1. Dental caries prevalence rate of primary teeth (dmf rate) was 61.7% at 3 years of age, 88.7% at 4 years of age, and 92.6% at 5 years of age (p>0.05). 2. Average score of dmft index was 2.22 at 3 years of age, 4.97 at 4 years of age, and 6.62 at 5 years of age (p>0.05). 3. Most of the caries-prevailed tooth was maxillary primary central incisor and showed 28.8% at 3 years of age, 56.7% at 5 years of age. 4. dmft index and dmfs index of children of Vietnamese, Cambodian, and Filipinos women were higher than those of Chinese and Japanese. 5. In sagittal primary molar relationship, flush terminal plane type was 82.6%, distal step type was 5.2% and mesial step type was 8.4%. This study is the first report for children of multicultural families in Korea. More attention for children of multicultural families will be needed in aspect of oral disease prevention and treatment.

  • The purpose of the present study was to evaluate the relationship between the malocclusion and dental caries in adolescents with permanent dentition. The subjects of the study were 385 adolescents aged 12 to 15 years. Dental Aesthetic Index (DAI) and DMFT index were recorded as clinical indicators of malocclusion and dental caries. The mean Dental Aesthetic Index (DAI) score of the subjects was 12.42 and the mean DMFT index of the subjects was 2.89. Four students (1.04%) were included in the group of orthodontic treatment mandatory, which signifies the handicapping malocclusion. Moreover, the result of gender-specific analysis of the DAI components observed that the prevalence of midline diastema and mandibular overjet were significantly higher among boys (p < 0.05). In 7 components (missing teeth, incisal segment crowding, maxillary anterior irregularity, mandibular anterior irregularity, mandibular overjet, anterior openbite, antero-posterior molar relationship) among the 10 DAI components, abnormal groups showed significantly higher DMFT index than normal groups (p < 0.05). The subjects in the group of definite to handicapping malocclusion (DAI ${\geq}$ 26) showed significantly higher DMFT index than the subjects in the group of minor or no malocclusion (p < 0.01). In addition, the DAI score had significant positive linear correlation with the DMFT index (r = 0.584, p < 0.01). Consequently, the current findings suggested a positive relationship between the malocclusion and caries prevalence. And several specific types of malocclusion were supposed to be significantly correlated with dental caries.

  • This study aims to evaluate the influence of vitamin and mineral supplement intake, and degree of calcium and phosphorus intake on occurrence of dental caries in primary teeth. Research data was derived from the Fourth Korean National Health and Nutrition Examination Survey (KNHANES) and 1,139 Korean children of 3 to 6 years were selected as subject for this study. The dft index, nutrition factor including vitamin or mineral supplement intake and degree of intake for calcium (Ca) and phosphorus (P) were identified. Chi-square test was performed to assess the difference in socioeconomic status, oral health behavior and nutrition factor, including vitamin or mineral supplement intake and degree of intake for Ca and P. Linear regression analysis was performed to identify the relationship between the dft index and the related variables. As a result, the dft index was increased with the age. Significant differences in Ca intake was examined according to the sex, and P intake was different according to the sex in 3-year-old group. Among the 4-year-old children, the vitamin and mineral supplement takers had 1.206 less dft index than the non-takers. In conclusion, intake of Ca, P and vitamin/mineral supplement was not a pivotal factor to influence the incidence of primary teeth caries. However, significantly low dft index was observed from 4-year-old group who intake vitamin or mineral.
