Objectives: This study aimed to examine the effect of the Oral Health Education Program (OHEP) on the change in the children's brushing behavior and reduction in the dental plaque index (PI) and to identify changes in their parents' perception of oral health. Methods: The OHEP was applied 44 children recruited from two childcare centers. We conducted a self-reported survey of the parents at baseline and evaluated the oral conditions of the children at baseline and after 5 weeks. Their brushing behavior was assessed once a week during the OHEP intervention period and daily at home thereafter. We measured the PI after a 12-week follow-up and performed repeated measures analysis of varience. Results: The average PI score of children significantly decreased at week 5 as compared to the baseline (1.90±0.53, p<0.001), despite a substantial increase in week 12 (2.67±0.08, p<0.001). OHEP was effective in reducing the PI score and modifying their brushing behavior. Conclusions: OHEP effectively modified the brushing the behavior of the children. Therefore, it is necessary to develop and expand a systematic oral health education program to promote self-management of oral health in children.

The purpose of this study was to evaluate the validity of dental hygienist job according to judgment standard of medical practice in medical law. In this study, we conducted a self-administered questionnaire survey to evaluate the validity of dental hygienist job for 12 professors of dental college in Gangneung-Wonju National University from November 10 to 20, 2017. We investigated whether the dental hygienist job conforms to the three criteria of medical practice such as disease prevention and treatment, patient care, and health hazard. The response rates were scored and classified into four categories according to the final score. As a result of this study, dental hygienist job are classified into four categories according to judgment standard of medical practice. The higher the level of the category, the higher the degree of difficulty, and the higher the level of expertise and skills required. More than 50% of respondents answered that measuring the gingival pocket, bleeding on probing, professional tooth cleaning, oral health education, counseling after dental treatment are all three criteria for medical treatment. And these were classified into Level 4 group which requires the difficulty and expertise in the final score 4.3. It is necessary to develop and utilize standardized guidelines on the level of knowledge, education, and qualification standards required for dental practice in order to effectively allocate work among the dental personnel while ensuring the health rights of patients in the dental clinic field in Korea. In addition, there is a need to evaluate the various aspects of cost effectiveness, dental health service productivity, and health promotion contribution to dental hygienist jobs, And based on this evidence, it is necessary to continue to expand and adjust the dental hygienist job and to reorganize the dental workforce system.

Dental caries has a multifactorial aetiology in which there is an interplay of three principal factors: the host(saliva and teeth), the microflora(dental plaque) and the substrate(diet), and a fourth factor time. There is no single test that takes into consideration all these factors and can accurately predict an individual's susceptibility to dental caries. The risk of dental caries can be evaluated by analysing and integrating several causative factors. The objective of the study was to clarify the relationship between caries activity and the status of caries of primary teeth and the relationship between the quantity of S. mutans in the dental plaque and the status of dental caries. Forty nine children ages 5 were examined with caries indices, Dentocult-SM and quantity of S. mutans. The results were as follows: All the survey results were similar with national means of 5-6 years Korean preschool children. The deft index of subjects was 5.46 and defs index was 9.81. There was 8.6% of negative, 10.9% of mild, 28.1% of moderate and 52.3% of active results at screening strip test. 8.6% was negative, 17.2% was mild, 33.6% was moderate and 40.6% was active in site strip test. The Spearman correlation coefficient was 0.775, and overall kappa index was 0.496 between screening strip test and site strip test. There also was a high correlation between caries incidence, Dentocult-SM test, and quantity of S. mutans. Dentocult-SM test as a caries activity test is a reliable method for measuring the status of dental caries in primary teeth.

The purpose of this study was to closely examine the inhibitive effect of erythritol on growth and acidogenic ability of Streptococcus mutans. As expected, the growth of S. mutans was comparably increased with the addition of sucrose. However, xylitol and erythritol remarkably reduced the growth of S. mutans. Growth inhibition was detected at more than 5% of erythritol although xylitol showed growth inhibition effect at all concentrations tested. Growth inhibition effect was monitored with the combination of same concentration of erythritol and other carbohydrates. Combination of 5% or 10% erythritol with xylitol showed effective growth inhibition. Addition of 2.5%, 5%, or 10% erythritol with sorbitol also showed growth inhibition. From these results, erythritol showed potency of growth inhibition of S. mutans, which is involved in dental caries, and was confirmed to be an excellent sugar substitute, which has effect on preventing caries.

Objectives: The purpose of this study was to determine the importance of brushing before sleeping by comparing the use of oral care products, frequency of dental clinic visits, and oral conditions between individuals who brush and do not brush their teeth before sleeping using data from the 5th and 6th Korean National Health and Nutrition Survey (KNHANES). Methods: Statistical analysis was performed using SPSS 21.0 on data files obtained according to a complex sampling design, and a significance level of <0.05 was set. General characteristics of the participants and year were analyzed using chi-square analysis. Data on the oral conditions, use of oral care products, and frequency of dental clinic visits were analyzed using logistic regression and linear regression. Results: Individuals who brushed their teeth before sleeping showed greater use of oral care products and more frequent dental clinic visits, oral examinations, preventive treatment, and treatment for simple caries (p<0.05) than individuals who did not. Individuals who did not brush their teeth before sleeping showed higher prevalence of permanent teeth caries and periodontal disease, as well as chewing and speaking problems (p<0.05), than those who bushed before sleeping. Conclusions: Individuals who do not brush before sleeping exhibit poorer oral health and lower use of oral care products and frequency of recent dental treatment than those who brush before sleeping. Therefore, it is necessary to alter the government's active policy and improve education about the importance of brushing before sleeping to improve oral health.

This study used 3 kinds of experimental toothpaste prepared with different contents of SLS, i.e. A (0%), B (1.1%), C (2.2%). These 150 subjects were subdivided again into three groups. After 4 weeks application of the three kinds of toothpaste, it was found that there were differences in dental plaque test (PHP) among the 3 groups; that is; a higher SLS content was associated with a lower PHP index. In addition, it was found that all 3 groups showed a reduction in simplified oral hygiene index (OHI-S). After 4 weeks application of the three groups of toothpaste, it was found that a higher SLS content was associated with a lower salivary flow, but there was no significant variation in salivary mucosity and pH. Further, it was found that SLS was negatively correlated with salivary flow, which supports the theory that SLS may induce xerostomia.

The present study purposed to prevent oral diseases and to improve oral health in children. For this purpose, we selected 70 cases who are 5~7 years old preschoolers at the kindergarten affiliated to G College in Gyeongsangbukdo, and analyzed the general patterns of oral care and the relation of the patterns with dental plaque and deciduous dental caries in the children. Specifically, we conducted oral examination and applied pit and fissure sealant according to the eruption of deciduous molar and first molar. In addition, we executed the 1st and 2nd tooth brushing instruction (TBI), and surveyed S-OHI and PHP twice. Excluding 14 preschoolers who did not appear in the 2nd survey, we performed the study with 56 preschoolers and drew conclusions as follows. 1. The number of decayed or missed or filled teeth among deciduous teeth was 3 or more in 42.9% of female children, and 46.4% of male children, so male children showed a slightly higher rate. 2. The degree of dental plaque formation was $1.64{\pm}1.22$ among the surveyed children. 3. The oral health index was lower after TBI than before in all the children (P<.001). 4. Change in the oral health index was particularly larger in 7 year old female children (p<.005). 5. The patient hygiene performance index was lower after TBI than before in both the buccal surface and lingual surface of the children (p<.005). 6. The patient hygiene performance index was lower after TBI than before in all of male children's teeth except the right maxillary first deciduous molar (p<.001).
