, Sang-Im Lee , Jae-Young Lee , Jong-Hwa Jang Abstract : Objectives: This study aimed to determine the relationship between English communication ability and job satisfaction of dental hygienists involved in the process of providing dental health services to foreigners and to analyze factors related to job satisfaction. Methods: Both online and offline surveys were conducted in parallel to measure English communication competency and job satisfaction. Participants were 195 clinical dental hygienists provided dental health services to foreigners. Spearman’s rho analysis was performed on the correlation between English communication ability, and job satisfaction, and a stepwise multiple regression analysis was performed on the factors related to the job satisfaction of the dental hygienist. Results: The job satisfaction of dental hygienists was 2.99 point out of 5 points. There was a strong positive relationship between English communication ability and english communication frequency (r=0.682), and the higher the English communication ability, the higher the job satisfaction (r=0.357). Factors affecting job satisfaction were English communication ability (β=0.378, P
Abstract : Objectives: The purpose of this study is to investigate the impact of COVID-19 on dental technicians and dental laboratories. Methods: In June 2020, self-reported questionnaires were distributed to and completed by dental technicians who attended the Seoul Dental Technologist Association’s academic conference (n=210). The responses were cross analyzed with frequency analysis (α=0.05). Results: Due to COVID-19, the number of employees has decreased to less than 20%, and sales of dental laboratories have decreased by 21-40%. On the Likert 5-point scale for individual precautions, ‘I wear a mask when using public transportation’ was the highest at 4.80. If infected with COVID-19, ‘my family’s infection is most concerned’ was the highest 3.89, but there was no significant difference between having children under the age of 13 in the family and having an elderly family over 65 years old (P>0.05). Conclusions: To prevent infection by dental technicians, it is mandatory to check body temperature when going to work and refrain from eating while working. As COVID-19 continues for a long time, it is necessary to continuously investigate the status of infected persons among dental technicians and vaccination rates as health care workers.
, Myung-Gu Lee , Joon-Haeng Lee , Yeol-Mae Jeon , Hyun-Jun Yoo Abstract : Objectives: This study aimed to evaluate the antibacterial activity of phytoncide on oral biofilm. Methods: Antibacterial activity of phytoncide was examined on the bacteria Streptococcus mutans, Aggregatibacter actinomycetemcomitans, Enterococcus faecalis, Porphyromonas gingivalis, and oral biofilm. After mixing the phytoncide, S. mutans, A. actinomycetemcomitans, E. faecalis, and P. gingivalis with a culture alone turbid and mixed, and they were then incubated at 37°C under anaerobic conditions and cultured. Following incubation, a microplate reader was used to measure the absorbance and observe the amount of bacteria. In addition, non-polarized saliva containing bacteria was grown for 72 h under anaerobic conditions for the determination of biofilm biomass and bacterial numbers. Various concentrations of phytoncide were added to the saliva biofilm. Statistical significance tests were conducted using the Mann-Whitney test and SPSS 24.0. Results: S. mutans, A. actinomycetemcomitans, E. faecalis, P. gingivalis, and antibacterial effects were shown as phytoncide concentrations increased in oral biofilm. Observing the growth of bacteria using phase difference microscopes showed that the number of bacteria decreases as the phytoncide concentration increased. Also, the formation of biofilm in the saliva decreased compared to the control group. Conclusions: Based on the experimental results of phytoncide on oral biofilms causing oral cavity formation in the saliva decreased compared to that in the control group. Phytoncide showed antibiosis against oral biofilms when it remained inside the mouth for above certain concentrations. Accordingly, using phytoncide as a clinical method for preventing oral disease is deemed to be effective.
, Deok-Young Park Abstract : Objectives: This study aims to determine whether National Health Insurance dental implant coverage increased instances of tooth extraction in older adults.Methods: Three periods were identified to analyze dental implant uptake in older adults-pre-coverage, intermediate-coverage, and post-coverage. Data for analysis were obtained from two sources. Frequency of tooth extraction and dental treatment data were obtained from the Healthcare Bigdata Hub. Data on the dental health status of older adults were obtained from National Health and Nutrition Examination Survey.Results: In 2019, the National Health Insurance supplied 10.2 dental implants per 100 older adults in Korea. The frequency of tooth extractions increased slightly after dental implant coverage for older adults, but statistically, the number of missing teeth was significantly reduced. Dental caries indices in older adults were also exacerbated during this period. The DMF rate and DMFT index for older adults increased significantly. However, the illness rate due to dental caries was also reduced. There was no significant difference in the prevalence of periodontal diseases. Based on the National health data and the frequency of related services, the slight increase in tooth extractions may be due to increased utilization of dental services.Conclusions: The authors could not find clear evidence that dental implant coverage increased the frequency of tooth extraction in older adults.

, Na-Yeoung Kim , Ji-Eun Kim , Choong-Ho Choi , Ki-Ho Chung Abstract : Objectives: The purpose of this study was to evaluate the tooth erosion potential of liqueur and to confirm the anti-erosive effect of calcium. Methods: After purchasing commercially available liqueur in Korea and measuring the pH, products with low pH and high consumption were selected and used as experimental beverages. Calcium (1%) was added to the selected beverages. Chamisul was used as a negative control, and Coca Cola was used as a positive control. Healthy bovine teeth samples were soaked in the selected beverages for 1, 3, 5, 10, 15, and 30 minutes. The changes in the tooth surface after beverage treatment were observed and analyzed using microhardness (VHN, Vickers hardness number) and scanning electron microscopy. Results: Jinro Grapefruit (-88.03±13.05) had the highest surface microhardness difference (ΔVHN) before and after 30 minutes of treatment in each group, followed by Coca Cola (-61.31±21.90) (P0.05). When comparing changes in surface microhardness over time, Jinro Grapefruit+Calcium (pH 3.75) had slightly lower surface microhardness than Chamisul, but the difference was not statistically significant. Jinro Grapefruit+Calcium has a lower surface microhardness change value than Coca-Cola and grapefruit dew group (P
, Hyo-Won Oh , Heung-Soo Lee Abstract : Objectives: This study aimed to examine oral health literacy (OHL) in mothers and the factors that influence it. Methods: A total of 431 mothers of preschool children were chosen as study participants using the convenience sampling method. A self-administered questionnaire was used in this study. The survey contents included the socioeconomic characteristics of the participants as well as their level of oral health literacy. Results: In total, 44.8 percent of the participants had a low level of verbal oral health literacy (0-6 grade), and 16.9 percent had a low functional oral health literacy (≤6). Educational level and family income were significantly associated with the participants’ oral health literacy (Pearson correlation). Verbal oral health literacy of the participants was related to their family’s income, whereas their functional oral health literacy was related to their educational level. Conclusions: Many of the participants had a low level of oral health literacy. For mothers, to improve their oral health literacy, an oral health literacy program must be in place. Oral health literacy programs should be targeted toward mothers with low socioeconomic status.
, Hyun-Ju Park , Hyang-Ah Park Abstract : Objectives: This study aims to understand the perceptions regarding preventive dental services among dental professionals. Methods: In-depth interviews were conducted with three groups of dental professionals―dentists, dental hygienists, and dental hygienists that specialized in preventive service―who were selected using a convenience sampling method. Results: First, there was limited awareness among dentists regarding the need for preventive care, because of the treatment-oriented philosophy and scarcity of preventive care success models. Second, dental hygienists commented that there was a lack of the person in charge and systematic process for preventive services. It would not help when they decided to change working place even though they had high anxiety working for preventive care. However, both these professionals agreed that preventive treatment is important as the core of care and that it was important to develop various improvement methods to promote preventive services. Conclusions: To activate preventive services in dental clinics, it is essential to improve the operating system and encourage dental professionals to realize the importance of preventive services.
, Ja-Won Cho , Hyun-Jun Yoo , Soon-Sung Kwon Abstract : Objective: This study aimed to investigate the characteristics of the high-risk group for dental caries among 12- and 15-year-old children in Laos. Methods: Oral health survey was conducted on 12-year-old (N=537) and 15-year-old (N=490) children in Laos. The oral examination data were listed from highest to highest based on the permanent caries experience index. Then the caries experience permanent index of the participants corresponding to the top third was calculated. In the final high-risk group, 179 and 163 children aged 12 and 15 years, respectively, were analyzed for the Significant Caries (SiC) Index. Results: The Decayed, Missing and Filled Teeth (DMFT) index of 12-year-old children in Laos was 1.59 (urban area 1.72, rural area 1.46), and the SiC index of the high-risk group for dental caries was 3.93 (urban area 4.01, rural area 3.85). DMFT index of the 15-year-old group was 2.04 (2.37 in urban areas, 1.74 in rural areas), and the SiC index of the high-risk group for dental caries was 5.17 (5.90 in urban areas, 4.49 in rural areas). Conclusions: Children aged 12 and 15 in the high-risk group for dental caries in Laos showed a higher caries experience permanence index than the overall average in the high-risk group. Based on the outcome of the investigation that the high-risk group had a lot of experience with dental caries, it is thought that the priority dental caries prevention project for the high-risk group of dental caries should be carried out.
, Yong Jeon Shin Abstract : Objectives: The high co-payment of dental care service providers reduces access to dental care and exacerbates health inequality among different social classes. Dental care services are affected by several socioeconomic factors including those related to the household, regional factors surrounding individuals, and individual factors. In this study, we identified household and regional factors that affect unmet dental care needs, after appropriately adjusting for individual-level and provided suggestions for improving the future coverage of dental and oral health care services. Methods: Using the 2019 Korean Community Health Survey data, 101,718 middle-aged (40-64 years old) and 72,807 elderly (65 years and older) individuals were analyzed to identify the unmet needs of dental care services by age group. To identify factors affecting unmet dental care needs by age group, a multilevel analysis of the overall rate (T1) was conducted with three dependent variables: (a)availability, (b)economic accessibility, and (c) acceptability. Results: The unmet need for dental care service rate (T1) was 15.43% for middle-aged individuals, 14.73% overall, and 13.00% for the elderly. The results of the multi-level analysis indicated that at the household level, the number of household members aged 19 years and above had an effect on the overall (T1) total unmet needs of dental care services and economic accessibility for the middleaged group. At the regional level, economic accessibility influenced the degree of financial independence and the number of dental hospitals and clinics per population. Conclusions: In order to reduce the unmet needs of dental care services, it is necessary to comprehensively consider not only individual-level factors but also household-level factors and regionallevel factors according to age.
