The aim of this study was to analyze the relationship between salivary flow, salivary buffer capacity, level of mutans streptococci and dental caries experience in Korean dental college students. A total of 81 students of the school of dentistry, Chonbuk national university, mean age of 26.1 years, were subjected to oral examination to establish the DMFT and DMFS according to WHO guidelines. Saliva samples from the students were collected for quantitating stimulated and unstimulated salivary flow rate. Buffering capacity was estimated using a commercial colorimetric strip test, and number of mutans streptococci was determined from stimulated saliva using a strip mutans test. The means of DMFT and DMFS were 6.57 and 12.65, respectively. The stimulated salivary flow rate was correlated with DMFT(${\acute{o}}\;=\;-0.219$) and high levels of salivary mutans streptococci were significantly correlated with higher DMFT and DMFS scores(P<0.05). Level of mutans streptococci was significantly correlated with dental caries experience, in both DMFT and DMFS score, and buffering capacity was inversely correlated to DMFT score. However, unstimulated salivary flow rate was not correlated with caries experience.

Periogen is a new caries activity test using real-time polymerase chain reaction. The aim of this study was to assess the validity of Periogen by evaluating the correlation with dmft, dmfts indices and comparing with Cariview and caries risk assessment tool (CAT). 83 children under 6 participated in this study. Dmft, dmfts indices and CAT were collected through an examination of oral health status. Plaque samples for Periogen and Cariview were collected and manipulated according to the manufactures' instructions. The correlation coefficient of Periogen, Cariview and CAT with the dmfts index were 0.38, 0.56 and 0.66 in each (p < 0.01). The sensitivity of Periogen, Cariview and CAT were 43%, 76% and 95% and specificity were 80%, 72% and 74% respectively. Area under curve under the receiver operating characteristic curves in each method indicated 0.69, 0.81 and 0.85. CAT and Cariview were more effective in evaluation the risk of dental caries than Periogen so far. To be used Periogen clinically, more improvements for higher validity were needed.
This study surveyed and analyzed on the relationship between obesity and oral health in early child hood and on the oral health realities targeting 90 young children at K Child Care Center where is located in Gangwon-do Province from 10 to 11, June, 2011. As a result, DMF rate accounted for 56.7%. D rate accounted for 42.2%. The young children with the higher age, height in 100~110cm, and weight in 25 kg were indicated to be higher in DF rate than other toddlers. The young children with height in 110~115 cm were indicated to be higher in prevalence of dental caries in deciduous teeth than other young children. It was indicated that the young children in the higher age and weight leads to the higher in DFT index and DFS index. It was indicated that the young children in the more overweight leads to the higher in the index of dental caries in primary teeth, the filling deciduous teeth index, DFT index, DMFS, and DFS index. Accordingly, the child care center needs to systematically perform the oral health education and oral health management for young children, to allow Young children to acquire right food habit, and to pay close attention even to selecting snack.

Objectives: The purpose of this study was to analyze the influence of four lifestyle-related diseases, diabetes, hypertension, obesity and hypercholesterolemia, on oral health in the rural elderly in Korea. Methods: We enrolled 399 subjects over 60 years of age over a six year period, year 2000-2006/ year 2001-2007. All subjects received a routine health examination as part of a program conducted by the National Health Insurance Corporation at Seongju-gun Public Health Center in Gyeongsangbuk-do Province, South Korea. All subjects were surveyed and examined to determine their general and oral health statuses. Results: Our results suggest that the duration of lifestyle-related diseases has a significant influence on oral health. The following factors were all significant in the results of analyses: duration of diabetes, tooth decay, which teeth had decayed, missing and filled teeth(DMFT), duration of hypertension, and duration of obesity and hypercholesterolemia(p<0.05). Our results also suggest that the number of lifestyle related diseases has a significant influence on oral health. Subjects with more than two diseases had significantly greater numbers of missing teeth and greater numbers of DMFT(p<0.01). The results of simple regression analysis indicate that patients exhibiting longer durations of diabetes also exhibit more tooth decay, and that patients exhibiting longer durations of hypertension and obesity are characterized by greater numbers of missing teeth. The longer the duration of any of the four lifestyle-related diseases we considered, the more DMFT we observed. Multiple regression analyses also demonstrated that longer duration of lifestyle-related disease was associated with greater numbers of missing teeth. As the number of lifestyle-related diseases increased, DMFT also increased. Conclusions: In summary, lifestyle-related diseases such as diabetes, hypertension, obesity and hypercholesterolemia have significant influences on oral health in the elderly. In this context, the prevention and management of lifestyle-related disease is critical for the maintenance and promotion of oral health.

The purpose of this study was to develop a practical caries activity test using laser fluorescence. The subjects of study were 30 children of $7\sim10$ years old. Fluorescence from initial carious lesion of teeth illuminated by an argon laser(488nm) was observed through barrier alter. For evaluation of accuracy and propriety of this method fer caries activity test, teeth with initial caries lesion on buccal or labial surface of children was examined with visual inspection and laser fluorescence. Visual examination for the dDfFtT and the $Cariescreen^{(R)}$ test were also done. The results from the present study can be summarized as follows: 1. Laser fluorescence test could differentiate initial caries lesions more easily than visiual inspection. 3. There was highest correlation(= 0.73) between laser fluorescent test and $Cariescreen^{(R)}$ test and. And also apparent correlation(= 0.66) exists between laser fluorescent test and caries experience measured by dDfFtT.

A new colorimetric test ($Cariview^{(R)}$) using a new type of pH indicator can reflect the acidogenic potential of plaque bacteria. The objective of this study was to evaluate the correlation between $Cariview^{(R)}$ and the caries experience (measured through the dmft index) of children, and to compare $Cariview^{(R)}$ with Dentocult $SM^{(R)}$. Having obtained informed consent, 135 children less than 6 years old participated in the study. We examined their dmft index, and performed two caries activity tests ($Cariview^{(R)}$ and Dentocult $SM^{(R)}$) according to the manufacturers' instructions. In the results, $Cariview^{(R)}$ showed a moderate correlation with the dmft index (r = 0.43, p < 0.01). $Cariview^{(R)}$ showed a sensitivity of 68.8%, a specificity of 69.2%, and an area under curve of 0.686 in the ROC curve analysis. $Cariview^{(R)}$ had a significant correlation with the children's caries experience and had a slightly better explanatory ability than Dentocult $SM^{(R)}$. Furthermore, $Cariview^{(R)}$ was convenient and easy to use on uncooperative children, and also had an educational effect with its visual colors. It is suggested that $Cariview^{(R)}$ could be used clinically to identify the children susceptible to develop caries and to establish a preventive strategy.
The present study attempts to find the ways to efficiently manage dental caries, one of the major causes of tooth loss, and to cope with oral diseases that deteriorate oral health. For this purpose, this study seeks to obtain fundamental data needed in planning the oral health projects. The study was conducted to the first-grade elementary school students in Hwa-Seong city, Gyeonggi-do, from April 1 - 30, 2002. The result was as follows: 1) Among a total of 2,710 subjects, 598 (274 boys and 324 girls) have more than 1 permanent tooth with a caries legion whether it was treated or not. 2) The number of permanent teeth examined is 6,029, in which girls' teeth are more (3,165) than boys' (2,864). 3) Out of a total of 6,029 teeth examined, 1,106 permanent teeth (508 boys' and 598 girls') have caries legions. 4) Out of 1,106 permanent teeth with caries legions, 170 (15.4%) were treated - 67 teeth for boys (13.2%) and 103 teeth for girls (17.2%). 5) 22.1% of the children have experienced dental caries in their permanent teeth. Among them, 20.1% are boys and 24.1% are girls. 6) The rate of the permanent teeth that once had, or now have caries legions are 21.2%, among which the rate for boy's teeth is 20.1% and that for girl's teeth is 22.1%. 7) The number of the permanent teeth that had caries legions is 0.5 for all the subjects. A boy has 0.4 and a girl has 0.5 teeth with caries legions regardless of whether it was treated or not. 8) The rate of the permanent teeth with caries legions is 86.7% for overall subjects - 88.3% for boys and 85.3% for girls. 9) The rate of treated permanent teeth is 13.3% for all the subjects - 11.7% for boys and 14.7% for girls. Based on the above result, the study draws a conclusion that in order to prevent dental caries in young students and to perform an early treatment for the dental caries that already occurred an oral health office should be installed at all the elementary schools so that elementary school students don't experience a loss of time and effort for learning and suffer nutritional imbalance or disorder. Besides, the oral health education concerning the importance of dental care should be conducted to the citizens, especially to the young people, in the community as an essential project of oral health centers in the community health offices, the public medical institutions.
The aim of this study is to identify the relationship between obesity and dieting to dental care in a convergent manner. This is a secondary analysis study using data from National Health and Nutrition Survey(2008 & 2018), and the subjects of the study are those with permanent treatment experience. The data in this study were t-test, ANOVA and regression analysis using SPSS /WIN 24.0. As a result of the study, The experience of permanent tooth caries according to gender was high in woman(M=.76, W=.83), and the experience of permanent tooth caries according to the educational level showed that the caries experience of high-educated level(College or higher=.92). In the difference according to the subjective body type recognition, it was confirmed that obesity was associated with the experience of permanent tooth caries. Among the weight control methods, fasting was the most influential on the permanent tooth caries experience. The experience of permanent tooth caries according to the weight change was found to have an effect on both weight loss and increase, In future studies, not only studies of sugar intake related to obesity, but also proper oral health education study that informs about the risk of dental caries in the diet that is progressing in line with the current trend should be continued.
The primary purpose of this report is to investigate the index of dental caries experiences and the state of oral hygiene for the children with mental retardation, cerebral palsy, and autism. In order to get those things we investigated 99 students that ages from 8 to 13 in three special schools (which are the school for the children with mental retardation, physical difficulties, emotional disturbance). Then collected the statistics and examined if there were some regardful differences among each type. (1) The investigation shows that there is no regardful differences among them in statistice. However, the averages of their dental caries experience have a little gap. The average of the children with mental retardation group is the highest and the autistic children group is the lowest, as we can see the facts of 4.70 for group of children with mental retardation, 4.58 for group of children with cerebral palsy, 3.67 for group of autistic children, children with mental retardation group is severe, autistic children group is few. (2) The conclusion from research of oral hygiene among each type, statistically regardful differences were revealed (p<0.05). It shows children with cerebral palsy is on worst state, children with mental retardation is on next state, autistic children is on best state by compare for averages among each type, 32.30 for group of children with mental retardation 35.00 for group of children with cerebral palsy, 27.79 for autistic children.

The purpose of this study was to compare the validity of $Cariview^{(R)}$, a new colorimetric caries activity test, with $CRT^{(R)}$ bacteria, a conventional bacterial culture method. In addition, this study assesses the correlation between the dental caries experience and activity between mothers and their children. 34 pairs of mothers and their children under the age of 6 years participated in this study with informed consent. After filling out a questionnaire and oral examination, the two caries activity tests above were performed on each subject. In the results, $Cariview^{(R)}$ scores were statistically significant with children's caries experience (r = 0.598, p < 0.01) and showed higher correlation than $CRT^{(R)}$ bacteria scores. $Cariview^{(R)}$ scores showed statistically significant correlation with the number of decayed teeth in both mothers and children (p < 0.05). In both $Cariview^{(R)}$ and $CRT^{(R)}$ bacteria tests, there was no statistically significant correlation between caries experience and caries activity (p > 0.05). $Cariview^{(R)}$ colorimetric test will be clinically useful for predicting future caries risk and establishing a preventative strategy in pediatric dentistry.
