To improve oral hygiene management, the effects of toothbrush training on general oral hygiene based on the simplified oral hygiene index(S-OHI) and degree of knowledge about toothbrushing were examined. Pre-and post-training changes in the S-OHI (lower score = better oral health status) showed a significant decrease in score in all variables (gender, age, marital status, occupation, and level of education).Pre- and post-training changes in the degree of knowledge about toothbrushing showed a significant increase. Negative correlations between the S-OHI, oral health status, and degree of knowledge about toothbrushing and the S-OHI and the Decayed, Missing, Filled (DMF) index (the better the oral cavity environment, the lower the DMF index) were observed. Positive effects of repeated toothbrush training on the maintenance of healthy oral cavity environment and continuous oral health management were observed, as reflected by the correct toothbrushing-related knowledge and skills.

Objectives: This study examines the association between emotional support and tooth brushing according to family cohabitation in the socio ecological model. Methods: The study used data from face-to-face interviews of 719 adults aged 30-90 years, living in Gangwon State. The dependent variables were tooth brushing after lunch and dinner (including before going to bed). The independent variables were living conditions and emotional support. Multiple logistic regression analysis was conducted to confirm the association between emotional support and tooth brushing. Results: The results showed that 81.4% of people lived with their family, and 85.9% had family (friends) with whom they could share oral problems (p<0.01). Among those living with their family, 82.3% (p>0.05) brushed after lunch and 81.9% (p>0.05) brushed after dinner. Tooth brushing after lunch was 1.5 times more likely among those who shared oral problems with their family (friends); however, this was not statistically significant (95% CI: 0.92-2.29). Tooth brushing after dinner was 1.0 times more likely among those who shared oral problems with their family (friends); however, this was not statistically significant (95% CI: 0.43-2.35). Conclusions: Emotional support may help to promote tooth brushing practice among adults.

The purpose of this study was to evaluate the abrasion resistance of surface penetrating sealant which was applied on a composite resin restoration and to provide proper time to reapply sealant on composite resin surface. Two hundred rectangular specimens, sized $8\times3\times2mm$, were made of Micronew (Bisco, Inc., Schaumburg, IL, U.S.A) and divided into two groups; F group (n = 10) was finished with coarse and medium grit of Sof-Lex discs and BisCoverwas applied B group (n = 190) after finishing with discs. B group was again subdivided into nineteen subgroups From B-1 group to B-18 group were subjected to toothbrush abrasion test using a distilled water-dentifrice slurry and toothbrush heads B-IM group was not subjected to toothbrush abrasion test. Average surface roughness (Ra) of each group was calculated using a surface roughness tester (Surfcorder MSE-1700: Kosaka Laboratory Ltd., Tokyo, Japan) . A representative specimen of each group was examined by FE-SEM (S-4700: Hitachi High Technologies Co., Tokyo, Japan). The data were analysed using cluster analysis, paired t-test, and repeated measure ANOVA. The results of this study were as follows; 1. Ra off group was $0.898{\pm}0.145{\mu}m$ and B-IM group was $0.289{\pm}0.142{\mu}m$. Ra became higher from B-1 group $(0.299{\pm}0.48{\mu}m$ to B-18 group $(0.642{\pm}0.313{\mu}m$. 2. Final cluster center of Ra was $0.361{\mu}m$ in cluster 1 $(B-IM\simB-7)$, $0.511{\mu}m$ in cluster 2 $(B-8\simB-14)$ and $0.624{\mu}m$ in cluster 3 ($(B-15\simB-18)$. There were significant difference among Ra of three clusters. 3 Ra of B-IM group was decreased 210.72% than Ra of F group. Ra of B-8 group and B-15 group was increased 35.49% and 51.35% respectively than Ra of B-IM group. 4. On FE-SEM, B-IM group showed the smoothest resin surface. B-8 group and B-15 group showed vertically shallow scratches , and wide and irregular vertical scratches on composite resin surface respectively. Within a limitation of this study, finished resin surface will be again smooth and glazy if BisCover would be reapplied within 8 to 14 months after applying to resin surface.

In this study, 110 adults aged 40 to 69 years were surveyed from April 28, 2016, to May 28, 2016 to analyze their periodontal status according to daily stress, coping methods, and oral health behavior. The collected data were analyzed using the t-test, one-way analysis of variance, and hierarchical multiple regression. Daily stress levels of all subjects were most frequent potential risk 64.5% of the subjects, the high risk 19.1% and 16.4% of the health group. Regarding stress coping methods, active methods recorded 2.46, passive methods recorded 2.32. Regarding oral health behaviors, subjects brushed an average of 2.45 times daily, for an average of 2 minutes. Futhermore, 69.1% of subjects brushed before bedtime and 89.1% practiced scaling. Regarding periodontal status, the O'Leary index was 73.45, gingivitis index was 1.30, an average of 2.83 quadrants possessed a periodontal pocket. The hierarchical multiple regression analysis identified, type of employment (${\beta}=-0.348$), scaling (${\beta}=-0.253$), and age (${\beta}=0.244$) as factors that influence the number of quadrants possessing a periodontal pocket. These results confirmed that the oral health behavior of scaling, but not stress levels of coping methods, strongly influenced periodontal status.

It is widely believed that the increase in the prevalence of dental erosion is due to soft drinks. The purpose of this study was to assess the influence of soft drinks and etchant on the erosion of tooth enamel and the effect of tooth brushing on the abrasion of eroded enamel, and the effect of milk, saliva and Tooth $Mousse^{(R)}$ on the remineralization. The changes in tooth enamel surface were observed by scanning electron microscophy. The results were as follows; 1. The pH of Coca-Cola and Chilsung-Cider were higher than the pH of FineEtch 37 and $Tyrian^{TM}SPE$. 2. The SEM photos revealed that the pattern of the surface eroded by Coca-Cola and Chilsung-Cider were more obvious than that eroded by etchants. 3. The results of remineralization by saliva, milk, Tooth $Mousse^{(R)}$ were not different from each other. 4. The remineralization by saliva decreased tooth brushing abrasion.

This study was to figure out the influence of oral health behavior and periodontal status on their OHIP-14. Explained to 255 people who visited the scaling center of Dental Hygienics of a college in Gyeongbuk from March 7th to June 13th 2014 and it was agreed to perform. Result of dental plaque and calculus rate of those with no TBI were high; the less frequent do they teeth brushing the higher were their rate of dental plaque, bleeding and calculus, while their OHIP-14 was low. The rate of calculus of whom with no education on dental floss use and who do not use dental flosswas high. The more powerful for those with higher rate of dental plaque; while the lower was the rate of calculus the higher was OHIP-14. Therefore, the more do they brush their teeth and the lower are the rate of their calculus, the more positively has it been figured out to influence on the quality of their life of oral health. Consequently, public health program should be developed to educate them on the necessity of scaing on a regular basis and the cause calculus of occurrence, as well as a media through which they can easily participate in the program.

The purpose of this study was to examine the relationships between depression, stress, self-esteem, oral health-related quality of life (OHIP-14) in middle-aged women. Data were as collected by self-reported questionnaires from 205 middle-age women. The instruments were the Center for Epidemiologic Studies Depression scale (CES-D), Brief Encounter Psychosocial Instrument (BEPSI), Self-Esteem Scale (SES). The data were analyzed using t-test, one-way ANOVA, Pearson correlation coefficients and multiple regression with IBM SPSS Statistics ver. 21.0. Pearson correlation coefficient analysis found that oral health impact profile (OHIP) was significantly associated with depression (r=-0.560, p<0.001), stress (r=-0.595, p<0.001), self-esteem (r=0.522, p<0.001). The OHIP was explained 39.4% by stress (${\beta}$=-0.362, p<0.001), self-esteem (${\beta}$=0.203, p=0.009) using multiple regression analysis. These results indicate that the intervention program of oral health promotion for community-middle- aged women is needed from now on.
