Statement of problem. Luster loss in esthetic anterior ceromer restoration can occur and can be related with rough surface texture. Understanding durability of surface finishing methods like polishing and surface coating have critical importance. Purpose. This study evaluated the effect of tooth brushing and thermal cycling on surface luster of 3 ceromer systems (Artglass, Targis, Sculpture) treated with different surface finishing methods. Material and methods. Seventy-two samples were prepared: 12 for control group Z100, 12 for Artglass, 24 for Targis, and 24 for Sculpture. Half of the Targis and Sculpture were polished according to the manufacturer's recommendation. The rest of the samples were coated with staining and glazing solution for Targis and Sculpture, respectively. All specimens were subjected to 10,000 cycles between $5^{\circ}C\;and\;55^{\circ}C$ with 30 seconds dwell time. Tooth brushing abrasion tests were performed in a customized tooth brushing machine with 500g back and forth for 20,000 cycle. Luster comparisons were based on grading after direct observation, and light reflection area was measured with Image analysis software. Results. All materials showed an decrease in luster grade after thermal cycling and tooth brushing. The post-tooth brushing results revealed that the glazed Sculpture had greater mean luster grade than did any other groups. While, the stained Targis group showed greatest changes after tooth brushing (p < 0.05), polished Targis and Sculpture did not show significant changes. However, glazed Sculpture showed discretely fallen out glaze resin. Conclusion. From the results of this study, all of the ceromer specimens were much glossy than control composite group after tooth brushing. coatings used for Targis and Sculpture had not durability for long term use.
Background: In this study, we investigated the changes and factors that affect daily health behaviors due to COVID-19 among adolescents. We intend to provide basic data so that a systematic and comprehensive health education program that includes physical and oral health can be made. Methods: This study was a secondary data analysis of the from the 2019 and 2020 Korea Youth Risk Behavior Web-based Survey. A final sample of 112,251 participants was anlayzed using chi-square test, and ordinal logistic regression. Results: In the case of tooth brushing, the frequency of 'never' increased in most general characteristics compared to before COVID-19. In the case of handwashing, it was found that handwashing behavior increased (increased) after COVID-19 compared to before COVID-19. As a result of confirming the factors affecting tooth brushing behavior before and after COVID-19, it was found that girls brushed teeth 2.2 times more regularly after lunch than boys. As a result of adjusting all other factors, regular tooth brushing behavior after COVID-19 was reduced by 0.79 times compared to before COVID-19. Conclusion: It is judged that it is necessary to operate a comprehensive health management program in the school so that the most basic tooth brushing for oral health and handwashing for health can become a habit. In addition, by confirming the impact of the COVID-19 pandemic on handwashing and tooth brushing behavior through this study, it is expected to be used in the development of policy data such as raising awareness of brushing and improving behaviors applicable in the current and upcoming new pandemic situations.
Background: Like direct infection from COVID-19, psychological concern about infection could affect health. Concern about COVID-19 infection was associated with individual habits to practice rules for preventing infection. Therefore, this study aimed to check occupational types and whether to practice tooth brushing after lunch depending on the occupation of economic workers and find correlations between concerns about infection due to COVID-19 pandemic and tooth brushing after lunch. Methods: The raw data was from the community health survey conducted in 2020. Among 229,269 adult participants aged 19 years and older, 138,970 economic workers were included in the final analysis. The chi-squared test was used to find differences in psychological concerns due to the COVID-19 pandemic. According to the participants, the rate of practicing tooth brushing after lunch was based on COVID-19-related psychological concerns. Multiple logistic regression analysis was conducted to check the influence of psychological concerns due to the COVID-19 pandemic on the rate of practicing tooth brushing after lunch. Results: According to occupational classifications, professionals and office workers and career soldiers had 1.551- and 1.581-times higher practicing rates than managers, respectively, whereas machine operators, agricultural and fishery sector workers, and daily laborers had lower practicing rates. Regarding COVID-19-related psychological concerns, the group with a lower concern about infection had a 1.076 times higher practicing rate than that with greater concern. The group with greater concern about blame from neighbors had 1.119 times higher practicing rate than that with lower concern. Conclusion: The correlations between higher economic workers' concerns about infection and blame from neighbors and higher recognition of the necessity to prevent COVID-19 and practice tooth brushing after lunch were confirmed. It is necessary to prepare measures for practicing tooth brushing after lunch suitable to the characteristics of occupational types and work environments of economic workers.

When the exposure surface of restoration is brushed with various toothpaste in the mouth, wear or undesirable surface deposit of restoration can occur. Surface change of gallium alloys according to brushing and toothpaste may directly affect oral hygiene. The aim of this study was to evaluate the surface alterations of Gallium alloys during tooth brushing with different prophylactic agents. Two gallium-alloys and an amalgam as a control were investigated. Without and with brushing were applied with three kinds of prophylactic agents on the sample for 0, 1, 5, 10, 60 and 360 minutes. At each time interval, surface roughness was recorded by a profilometer and some pictures were taken by a SEM. All results were analyzed by the one-way ANOVA, followed by Tukey multiple comparisons and the simple linear regression analysis. The results indicate that gallium alloys are more susceptible to surface degradation during tooth brushing than amalgam with respect to the specific prophylactic agent used.
Ceromers, new indirect resin system, are now being adopted for esthetic restorations. Despite of its translucency and good color matching, color stability after long-term use was unknown till now. This in vitro study was designed to evaluate color stability of some ceromers when subjected to brushing after thermocycling. Three types of ceromers: Scupture, Targis, Artglass and a direct resin system, Z100 were prepared to disks 12 mm in diameter, 2.5 mm in thickness. All specimens were polished, and Sculpture and Targis specimens were divided two groups, respectively. Then, half of them were glazed according to manufacturer's instructions. All specimen were brushed 20,000 times after 10,000 cycle thermocycling. Color was measured with spectrophotometer after 1,000, 3,000, 10,000 times thermocycling and 20,000 time brushing, respectively. Color difference (${\Delta}E$) was calculated according to CIE LAB system. During thermocycling, Sculpture & Targis system with polished surface showed greater color change than any other groups. After brushing, color difference was reduced significantly. Mean values of ${\Delta}E$ ranged 0.98 to 2.98. All Ceromers were considered clinically acceptable after thermocycling and brushing, and color change mechanism was affected by the brands and finishing methods. It might be concluded that color change of ceromer is due to surface alteration.
This study was conducted to find proper material of brushing stimulation for height suppression of tomato plug seedlings. The tomato seeds were sown in 40-cell plug tray filled with commercial seedling medium and brushing stimulation was started at 18 days after sowing. Acrylic, polypropylene film, and weaving film were used by materials of brushing stimulation and, non-treatment and diniconazole treatment were used as the control. In acrylic treatment, the plant height was the shortest and the stem diameter was the thickest. Leaf growth was the lowest in diniconazole treatment. However, the SPAD value was the greatest in diniconazole treatment. The dwarf rate was the greatest in acrylic treatment. In acrylic treatment, the T/R ratio was the lowest and compactness was the greatest. In conclusion, use of the acrylic as material for brushing stimulation has higher dwarf rate than diniconazole treatment, and has advantages height suppression and seedling quality.

To maintain good oral hygiene, plaque control is essential and the most common and effective method is appropriate brushing. However accurate brushing is so difficult for children that the importance of brush is getting higher. We investigated the effect of tooth brushing instruction in plaque control for 40 children who came to Kyunghee university dental hospital, department of pediatric dentistry. We examined basic information by self-assessment, evaluated plaque index, tooth & tongue cleanness, malodor index for 4 times and compared values before and after tooth brushing instruction. Plaque index decreased(p<0.01) and tooth & tongue cleanness increased(p<0.01). There were no significant differences in mal-odor index. In conclusion, tooth brushing instruction is effective in removing dental plaque and its beneficial role is highly expected in establishing children's good oral hygiene.
In order to evaluate the effectiveness of tooth brushing, mouth gargling and gum chewing in reducing halitosis, 84 individuals ranging in age from 22 59 28 years old were examined. These individuals had no gross oral abnormalities, other than mild gingival inflammation, dental caries, nasopharyngeal disorder, or systemic diseases that were associated with halitosis. They were divided into a tooth brushing group, a mouth garging group, a gum chewing group and a control group that did not use any halitosis removing method. Each of the groups included 21 persons, B.B. Checker (Tokuyama Soda Col, LTDl, Japan) was used to measure the concentrations of intraoral volatile methyl mercaptan of each group. The concentrations of intraoral volatile methyl mercaptan were measured before and after lunch, and after removing halitosis by toothe brushing, mouth gargling and gum chewing. The obtained results were as follows : 1. The average concentration of intraoral volatile methyl mercaptan before lunch was 1.79ppm and after lunch it was 2.02ppm, an increase of 12.9%. 2. In the tooth brushing group the average concentration of intraoral volatile methyl mercaptan was 0.61ppm, in the mouth gargling group it was 1.15ppm, in the gum chewing group it was 1.64ppm and in the control group it was 1.92ppm. It decreased 69.5% in the tooth brushing group, 43.8% in the mouth gargling group, 18.4% in the gum chewing group and 5.4% in the control grop (p<0.05). 3. There were significant differences between the tooth brushing and control group, tooth brushing and gum chewing group and between mouth gargling and control group in concentrations of intraoral volatile methyl mercaptan after using the halitosis removing methods (p<0.05). According to the above results, tooth brushig and mouth gargling are effective ways to reduce halitosis.
