RESUMO
Background@#This study compares and analyzes the degree of oral health information literacy by 25% for upper and lower grades to assess how differences in mothers’ oral health information literacy affect infants’ oral health behavior. @*Methods@#The study surveyed 201 mothers with infants and children using a 36 question survey tool. Cross-analysis was conducted to determine the difference in oral health information literacy between the upper and the lower 25%. @*Results@#Comparing 25% of the upper and lower grades of verbal oral health information literacy scores, the word with the most significant difference in the correct answer was resin. An item asking about the time to eat after fluoride varnish application showed the most significant difference in the correct answer on the functional oral health information literacy scale. Mothers’ oral and functional oral health information literacy scores showed that verbal literacy was statistically significant for brushing guidance after children’s meals, brushing guidance before children’s bedtime, food intake restrictions before bedtime, and restrictions on consumption of cavity-inducing foods (p＜0.05). Functional literacy was statistically significant in the post-brushing test of children and the correct brushing method map items (p＜0.05). @*Conclusion@#As a result of comparing and analyzing the upper and lower 25% of the mother’s oral health information literacy, it was found that the mother’s oral health information literacy affected the infant’s oral health behavior. Therefore, systematic education is needed to raise literacy by grasping the level of oral health information literacy of mothers, and oral health education by level according to oral health information literacy should be developed.
RESUMO
Background@#This study aims to provide basic data for development of the level-based oral health care program depending on the mother’s oral health literacy by finding out how mother’s oral health literacy can effect on the preschool children’s oral health and behavior. @*Methods@#The survey was conducted on 192 mothers who have preschool children and the data were analyzed by t-test, ANOVA, multiple regression analysis to identify differences in verbal and functional oral health literacy. @*Results@#The study showed statistical significance (p＜0.05) in educational level depending on differences in verbal and functional oral health literacy by sociodemographic factor. In differences in verbal and functional literacy depending on experience of education for oral health behavior and oral health, statistical significance (p＜0.05) was showed highly on verbal and functional literacy in the case that subjects have an experience of education for oral health and their children have not been experienced of oral illness. And when it comes to the case that subjects have experience of education for oral health within one to two years, statistical significance was showed highly on verbal literacy. It showed that verbal and functional oral health literacy effects to oral health care behavior of children judging from results that the higher level of mother’s verbal oral health literacy, the higher score of children’s oral health knowledge, attitude and behavior. @*Conclusion@#It is necessary to develop the systematic program which is appropriate for characteristics of each oral period in childhood depending on level of primary caregiver’s oral health literacy, and systematic education should be preceded to enhance the literacy of the caregiver. It is considered necessary to improve the oral health care of children by developing a manual for oral health care education to enhance primary caregiver’s oral health literacy.
RESUMO
The purpose of this study was to evaluate the remineralization effect of experimental fluoride varnish mixed with nano-tricalcium phosphate (TCP) and nano-hydroxyapatite (HA) on bovine teeth under demineralization and remineralization cycling by Vickers hardness. After fabrication of rosin-based experimental fluoride varnish with 5 wt% of NaF (EX) in the laboratory, 10 wt% of nano-hydroxyapatite (HA+EX) and nano-TCP (TC+EX) were mixed, respectively. Casein phosphopeptide-amorphous calcium phosphate (Tooth mousse) (CP) was used for comparison. Bovine incisors were impregnated by acrylic resin and exposed to caries inducing solution for 72 hours. EX, HA+EX, TC+EX, and CP were applied on the surface of bovine teeth. The specimens were immersed in a demineralization solution for 1 hour and in a re-mineralization solution for 23 hours and the cycle was repeated for 20 days. Vickers hardness was measured at baseline and after each treatment. CP group showed the highest hardness value at 24 hours after application of each material (p0.05).On the 10th day of de-/re-mineralization cycling, the TC+EX group showed the highest hardness value (p0.05). On the 20th day, the TC+EX group kept the highest hardness value, followed by HA+EX and EX groups (p<0.05). In conclusion, experimental fluoride varnish with 10 wt% of nano-TCP showed higher remineralization effect on the enamel of bovine teeth during the de/re-mineralization cycling.
RESUMO
The purpose of this study was to evaluate the sustainability of antibacterial effect against Streptococcus mutans of experimental fluoride varnish mixed with 2-hydroxyethyl methacrylate (HEMA) and/or glutaraldehyde. Experimental fluoride varnish (EX1) was fabricated. To make fluoride varnish with adhesive materials, EX1 was mixed with 5 wt% of glutaraldehyde (EX2), 35 wt% of HEMA (EX3) or both 5 wt% of glutaraldehyde and 35 wt% of HEMA (EX4). 5 μL of each experimental group was applied to 6 mm diameter polyethylene terephthalate film discs. Disks were stored in distilled water in a shaking incubator at 37℃ for 1 hour, 3 hours, 8 hours, 12 hours, 24 hours, 5 days and 10 days. The antibacterial activities against S. mutans were evaluated by agar diffusion test with the discs at each time. The antibacterial activities were sustained up to 10 days in all groups. The antibacterial activities of EX3 and EX4 were significantly higher than other groups from 8 hours to 10 days and there were no significant differences from EX2 at 10 days. HEMA with and without glutaraldehyde can be applied to fluoride varnish to increase the sustainability of antibacterial activities.
RESUMO
We evaluated the antibacterial, anti-inflammatory, and inhibitory effect of osteoclast differentiation of Brachypodium sylvaticum (BS) to find out the possibility of preventing periodontal disease. The inhibition of Porphyromonas gingivalis (P. gingivalis) growth by BS and the sustainability of the antibacterial activity was assessed. The production of pro-inflammatory cytokines from lipopolysaccharide (LPS)-induced RAW 264.7 cells were measured using enzyme-linked immunosorbent assays (ELISA), and the production of nitric oxide (NO) and cell viability were measured. Osteoclast differentiation was evaluated by Tartrate-resistant acid phosphatase (TRAP) staining, and TRAP activity. BS showed significant antibacterial activity and sustainable antibacterial activity in P. gingivalis. We also found out that the BS significantly decreased secretion of pro-inflammatory cytokines [tumor necrosis factor (TNF-α) and interleukin-6 (IL-6)] and NO production without cytotoxicity. Furthermore, BS inhibited the differentiation of bone marrow macrophages (BMMs) obtained from mouse bone marrow cells into osteoclasts without cytotoxicity. Taken together, BS can be a promising candidate for a preventive and improving agent of periodontal disease having antibacterial, anti-inflammatory, and inhibitory effects of osteoclast differentiation.
RESUMO
This study aimed to evaluate the antibacterial activities sustainability of antibacterial agents mixed with experimental fluoride varnish on hydroxyapatite disc against Streptococcus mutans (S. mutans). On the hydroxyapatite disc with 4.8 mm of diameter, 5 μL of 1 mM antibacterial agents mixed with experimental fluoride varnish were applied. Positive control and vehicle control were 10 μg/mL ampicillin and dimethyl sulfoxide (DMSO) mixed with fluoride varnish, respectively. The discs were stored in distilled water in a 37℃ shaking water bath at 120 rpm for 30 minutes, 4 hours, 1 day, 5 days, 20 days, and 30 days. Antibacterial activities were evaluated with the inhibition zone by the agar diffusion test. The antibacterial activities of all antibacterial agents were sustained for 30 days. Among them, Bakuchiol, Bavachromene, and Bavachalcone showed higher antibacterial activities for up to 30 days. The antibacterial agents when mixed in the experimental fluoride varnish with increased and prolonged antibacterial activities can be applied to prevent dental caries effectively.

RESUMO
This study aimed to assess the sustainability of antibacterial agents mixed with experimental fluoride varnish (EFV) against S. mutans. Five antibacterial agents [Xanthorrhizol (XAN), Bakuchiol (BAK), Bavachalcone (BCC), Isobavachromene (IBC), and Bavachromene (BCM)] were used and incorporated into the EFV to make the final concentration of 10 mM. Then, 5 μL of antibacterial agents mixed with EFV were applied on polyethylene terephthalate film disc (5 mm diameter). The positive and vehicle control were ampicillin and DMSO mixed with EFV, respectively. Each group was stored in distilled water in a 37℃ shaking water bath at 80 rpm for 0 hour, 4 hours, 1 day, 2 days, 3 days, 5 days, 10 days, 20 days and 30 days. The sustainability of the antibacterial activities was evaluated with the inhibition zone by the agar diffusion test. The antibacterial activities of all antibacterial agents were sustained for 30 days. Among them, BCC showed relatively higher antibacterial activities up to 30 days compared to other groups. This study suggests that antibacterial agents including BCC can be used with fluoride varnish to have sustained antibacterial activities.
RESUMO
BACKGROUND: We investigated somatization symptoms experienced by dental hygienists due to stress from emotional labor. Our aim was to provide basic research data that could be useful in the development of efficient stress management schemes for this occupational group. METHODS: We analyzed data collected from 208 dental hygienists working in Jeollabuk-do Province, Korea. To measure the level and intensity of emotional labor among research participants, we used the Korean Emotional Labor Questionnaire. We used the Somatization Symptom Checklist-90-Revised (SCL-90-R) to measure the level of somatization symptoms among participants. RESULTS: On analyzing the level of emotional labor and somatization symptoms according to general characteristics, participants aged 23~25 years showed high scores for stress due to emotional labor (p<0.05). Working 5 days per week, subjective health status, and organizational support and protection systems were found to correlate with the level of stress due to emotional labor (p<0.05). In the analysis of correlations between emotional labor and somatization symptoms, scoring high across all domains of emotional labor was associated with scoring high for somatization symptoms in the subdomains of emotional labor. When emotional labor and demographical variables were used as independent variables, having higher scores for emotional labor and having poor subjective health status were found to be associated with having higher levels of somatization symptoms (p<0.05). CONCLUSION: Our results showed that working at night and organizational support and protection systems were correlated with emotional labor and somatization symptoms. Measures must be taken at the organizational level to reduce emotional labor and somatization symptoms.

The aim of this study was to investigate the antibacterial effect of fluoride varnish with antibacterial agents on Streptococcus mutans (S. mutans). Experimental fluoride varnish (EFV) with 5% NaF was fabricated. Five antibacterial agents were tested with 1 mM and 10 mM concentrations, respectively: Bakuchiol (BAK), Bavachalcone (BCC), Isobavachromene (IBC), and Bavachromene (BCM). MIC and MBC test was performed by antibacterial agents with and without EFV using 1.1 × 10¹⁰ CFU/ml of S. mutans. Cell viability test were performed using MTT test. Statistical analysis was done with ANOVA and Duncan's multiple range test at α=0.05. In the antibacterial agents without EFV, the MIC of BAK, BCC, and IBC was the lowest (0.015 mM), and the MBC of BAK was the lowest (0.031 mM). For the antibacterial agents with EFV, the MIC (0.031 mM) and MBC (0.062 mM) of BAK was the lowest, respectively. In MTT test, 1 mM BCM showed the highest cell viability (P < 0.05). This study suggest that BAK can be applied the fluoride varnish under the control of the concentration to develop antibacterial fluoride varnish.
