Background: Nowadays, dental health problems in Indonesia are still quite high. It is one of which influenced by low public awareness of the importance of maintaining the health of teeth and mouth that can be measured by toothbrushing behavior. Based on the results of RISKESDAS 2018, only 2.8 percent of the population has a proper toothbrushing behavior. Behavior tends to form at age 6 to 12 years. At this age, children begin to develop habits that tend to settle until adulthood, including toothbrushing behavior. Social cognitive theory is a theory of behavioral change that explains that behavioral changes are influenced by the environment, personal, behavior where these three factors influence each other. This study aims to identify changes in the dental behavior of second grades students before and after the joint toothbrushing at school for 21 days. Methods: A pre-experimental study-design was conducted on elementary school by pre-post treatment method where there are 2 classes that get intervention and 2 other classes as control. A joint toothbrush is performed every morning before the school activities begin. Before and after the joint toothbrushing, all classes are given questionnaires to see if there are any changes in behavior seen through knowledge, attitudes, and practice. Results: Respondent group showed increasement on their knowledge, attitudes, and behaviors towards toothbrushing. In contrast, the control groups showed no significant differences in the 3 factors. Conclusion: In this study the education of toothbrushing through environmental changes is quite effective in elementary school children. Insights into the benefits of this program and refinements of optimally targeted intervention, including longitudinal studies are needed to improve the results.

Purpose: This study is to investigate the distribution of natural tooth shades in the Korean elderly population to quantify the correlation and changes of tooth color with age and gender. In addition, the possible effects of habits on tooth color were assessed. Materials and Methods: The tooth color of one of the maxillary central incisors of 200 Korean individuals aged 50 to 89 years, males and female, was measured using the portable intraoral spectrophotometer (VITA Easyshade V). CIELab and CIELCh color coordinates were recorded. We conducted the survey about the tobacco smoking, chronic disease, medication, eating habits, oral health behaviors and satisfaction with tooth color. Experimental data were statistically analyzed by using the t-test (P<0.05), two-way analysis of variance and Pearson's correlation test. Result: The most frequent color in the Korean elderly population was 3M3 & A3.5 shade. L^* and h^* values decreased, whereas C^*, a^* and b^* values increased progressively with age. There was a significant interaction between age and color coordinates for b^* values (r=0.245, P<0.05). Males generally have significantly higher C^*, a^*, b^* values and lower L^*, h^* value compared to females. Individuals who consumed alcohol had a higher L^* value (P<0.05). Conclusion: Within the limitation of this study, the central incisors were getting darker, more reddish, and yellowish with age. Information on the chromatic range of natural teeth by age and gender could help to select colors for esthetic dental restorations.

This study was performed to assess the effect of eating behaviors and health-related variables on overall dietary quality. Ninety-four(male 21, female 73) elderly who were over 60 residing in middle income areas in Cheongju city participated. Information on general characteristics of the elderly, health-related life style, regularity of meal, meal balance and desirable eating habits were obtained by interview based on questionnare. Dietary nutrient intake data were obtained through the 24 hour recall method. The mean age and BMI of the subjects were 73.3 years old and 23.3(male 21.8 female 23.7) respectively. The proportions of underweight and hypertension were 19.2% and 36.2%. Most nutrients except vitamin $B_2$ and calcium were consumed over 75% of the RDA. The Mean Adequacy of Ratio(MAR) of nutrient intake was 0.64(male 0.72, female 0.62). The average score of regularity of meal, meal balance, and desirable eating habits was 14.4 out of a possible 16, 13.7 out of a possible 24 and 5.5 out of a possible 16 points respectively. Male than female, older subjects than young subjects, and those living with their spouses than with other family or living alone had better scores in eating behaviors. Smoking, chewing ability and eating alone vs eating with company affected overall of regulality of meal and meal balance(p<0.05). Positive correlation (p<0.05) was also dietary quality. There was a positive correlation between the mean adequacy ratio, score observed between scores in regularity of meal and meal balance. Therefore, the elderly should be encouraged to eat a variety of food, maintain good dental health, keep regularity of meal and have meals with company to help improve overall dietary quality and eventually achieve optimal nutritional status.

In this study, ion release and biocompatibility of sintered Ni-Cr-Ti alloy for dental prosthodontics have been researched by corrosion and cell culture test. The microstructures of the alloys were observed by optical microscope, and corrosion behavior was investigated using potentiostat (Model PARSTAT 2273, EG&G, USA). Cell culture was carried out using hGf cell in DMEM (Welgene Inc., South Korea) supplemented with 10% fetal bovine serum (FBS) (Welgene Inc., South Korea) and antibiotic antimycotic solution (Welgene Inc., South Korea). After corrosion and cell culture test, surface morphologies were observed by field-emission scanning electron microscopy. For wettability behaviors, contact angles were measured by wettability test. As the content of Ti increased, the number of pit decreased and the corrosion resistance was improved from anodic polarization test, also, polarization resistance of samples containing Ti remarkably improved as compared with the alloy not containing Ti. The sintered alloy showed a low contact angle due to the pores formed on the surface. The addition of Ti element showed that the cell survival rate was better than that of the control group.
