Abstract : Objectives: This study aimed to objectively evaluate factors associated with musculoskeletal disorders by measuring the range of motion of the cervical spine. Using three-dimensional motion analysis, the degree of flexion, lateral flexion and rotation were compared between dental hygiene students and dental hygienists during dental scaling. Methods: Muscle activity in the range of motion of the cervical vertebrae was measured in 35 dental hygiene students and 15 dental hygienists while scaling. Data were collected and processed using the biofeedback exercise function of the 2EM (4D-MT, Relive, Gimhae, Korea), an electromyography measuring device. A three-dimensional motion analysis sensor was attached to the subject’s right external auditory canal, and the joint angle was measured at 20 Hz. Results: Cervical flexion (15°-45°) was measured higher in dental hygienists than in students. Cervical flexion within 15° of the normal range was higher in students than in dental hygienists. For cervical lateral flexion of 15°-45° and >45°, dental hygienists measured higher than students. In contrast, cervical lateral flexion within 15° of the normal range was higher among students than dental hygienists. Cervical rotation (15°-45°) was measured higher in dental hygienists than in students. No dental hygienist’s cervical rotation measured over 45°, and more students reached the 45° measurement than dental hygienists. Conclusions: Flexion, lateral flexion, and rotation were measured higher in dental hygienists then dental hygiene students. The results indicated that the range of motion of the cervical spine in the two groups exceeded the average scores for normal flexion, lateral flexion, and rotation by more than 15°, thereby increasing the risk of musculoskeletal disorders.

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.

Abstract : Objectives: The purpose of this study was to identify whether stress experienced by those working in the local civil service was related to their oral health during the COVID-19 pandemic. Methods: A survey was conducted on 431 civil servants from eight districts, currently working in the Daegu City Hall had COVID-19 related work duties during the pandemic. Results: Several factors associated with oral health related quality of life were explored. Demographic details revealed that men had significantly better oral health related life quality as compared to women; further, being younger, being unmarried, and having a lower position had better outcomes for oral health related quality of life. Regarding the relationship between oral health behavior and oral health related quality of life, it was found that the better the subjective oral health, the higher the rate of not visiting the dentist in the past year. The COVID-19 pandemic has been a particularly important time to explore in order to understand how the stress experienced by local government officials is related to their oral health. It has been especially noted that the higher the work stress, the worse the oral health related quality of life amongst individuals. Conclusions: Results of this study emphasize that at a time when fatigue among civil servants is increasing due to the prolonged COVID-19 pandemic, oral conditions caused by stress should be identified and greater awareness should be created about oral health care.

Abstract : Objectives: The purpose of this study is to investigate the trend of dental caries inequalities according to the household income level of children and adolescents, using data from Wave 4 (2007-2009) to Wave 7 (2016-2018) of the Korea National Health and Nutrition Examination Survey (KNHANES).Methods: The raw data were obtained from the website of KNHANES. The data by year within each wave were integrated and used for the analysis. In accordance with the guidebook for data users, the experience rate and prevalence rate of dental caries in primary and permanent teeth were estimated. Additionally, the absolute difference (AD) between the lowest and highest household income levels and the prevalence ratio (PR) by household income level were calculated.Results: The AD in the experience rate of dental caries showed a tendency to marginally decrease in primary teeth and moderately increase in permanent teeth. The PR was not statistically significant (P>0.05) in all waves. The AD in the prevalence rate of dental caries decreased by 5.4% and 8.2% in primary and permanent teeth, respectively. The PR in Wave 7 showed that all statistical significance disappeared (P>0.05).Conclusions: In Korean children and adolescents, dental caries inequalities by household income level showed a tendency to gradually decrease in primary or permanent teeth, and statistical significance was no longer confirmed.

Abstract : Objectives: This study aims to determine the influence of social exchange relationships, leader’s political skills, job stress, job satisfaction, and organizational commitment on turnover intention among dental hospital hygienists. Methods: A self-administrated questionnaire survey was conducted from April 1-May 12, 2020, involving 209 dental hospital hygienists in Seoul, Busan, and Gyeongnam. The collected data were analyzed using SPSS and AMOS statistical analysis programs. Results: In the hypotheses testing, 9 of 18 hypotheses were supported. In social exchange relationships, job stress, job satisfaction, and organizational commitment, the path to turnover intention had a significant effect, but it was not statistically significant in leader’s political skills. With regard to mediating effect, job stress, job satisfaction, and organizational commitment played a complete mediating role in the path from social exchange relationships to turnover intention. Conclusions: To increase job satisfaction and organizational commitment, and lower job stress in order to have a positive impact on turnover intentions, it is imperative to develop and apply a program to enhance social exchange relationships.

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.
