    Abstract PDF
    The purpose of this study is to analyze the clinical dentistry curriculum in Korea and Japan in order to review the application of integrated curriculum in the field. We collected the clinical dentistry syllabi for 2015-16 of the department of dental hygiene of Korea G University and Japan N University. Using the data from Korea, items that were duplicated and integrated were classified by the subjects covered in clinical dentistry. In addition, through case studies conducted in Korea and Japan, we analyzed and compared the credits, class hours, teaching methods, and evaluation methods, by subject. In Korea the total class hours in clinical dentistry, including clinical practice, was 1,095, and in Japan it was 1,104. In Korea, the syllabus covered by each department consisted of about 200 hours centering on theoretical lectures. In Japan, the integrated form of clinical dentistry was taught, and the instructions included all the contents of clinical dental study and also problem-based learning for approximately 100 hours. To strengthen the competence of dental hygienists as professionals, who are actively involved in dental practice, it is necessary to integrate the education contents of segmented clinical dentistry from the perspective of dental hygiene. It is also important to apply teaching methods that can help students improve their ability to solve problems.

    Na-Ri Shin | 최준선 | 2019, 19(3) | pp.351~362 | number of Cited : 0
    Abstract PDF
    Objectives: The study aimed to analyze the factors affecting the maturity of dental biofilm, which was assessed with quantitative light-induced fluorescence-digital(QLF-D), in a sample of Korean older adults. Methods: This cross-sectional study included 67 participants, aged 65 years and older. All participants completed a questionnaire and tests to measure their manual dexterity and handgrip strength, which are parameters that indicate hand function abilities. To evaluate dental biofilm maturity, 804 surfaces of six index teeth were imaged using QLF-D and then quantified as ΔR values. All data were collected from May 25, 2017 to April 30, 2018. The independent t-test, one-way analysis of variance, and step-wise multiple linear regression were performed to analyze the factors associated with the maturity of dental biofilm (ΔR). Results: The multivariate linear regression analysis revealed that the factor most strongly related to dental biofilm maturity(ΔR) was manual dexterity (β=-0.326), followed by handgrip strength (β=-0.303) and use of interdental cleaning devices (β=-0.283) ( p <0.05). Conclusions: Manual dexterity, handgrip strength, and use of interdental cleaning devices are factors that can predict dental biofilm maturity in adults aged 65 years or older. Therefore, the hand function of a patient should be evaluated first, before assessing the oral hygiene status of the patient or providing him/her with oral health education, and the dental hygienist should provide differentiated oral hygiene care depending on the patient’s hand function ability. Finally, dental hygienists should help older adults to recognize the importance of auxiliary oral hygiene devices such as interdental brushes and keep motivating them to use the devices more frequently.

    Ju-Hui Jeong | So Jung Mun | Ja-Hae Yoo and 1other persons | 2019, 19(3) | pp.363~373 | number of Cited : 0
    Abstract PDF
    Objectives: The purpose of this study was to investigate nail hygiene behaviors and to identify the relationship between hand hygiene beliefs and nail hygiene behaviors among dental hygienists, dental’s aide and dental coordinator in South Korea. Methods: The subjects were 291 dental workers including dental hygienists, dental assistant and dental coordinator working full-time at dental clinics, dental hospitals, general dental hospitals and dental university hospitals in Seoul, Incheon, and Gyeonggi-do. The questionnaire consisted of a total 35 items, including 4 items on general characteristics, 25 items on hand hygiene, 2 items on “nail art” experience, and 4 items on nail hygiene behaviors. The collected data were analyzed using an independent t-test, one-way ANOVA, chi-square test, correlation analysis, and multiple linear regression analysis, where α<0.05 was considered statistically significant. Results: The scores of behavioral beliefs, normative beliefs, control beliefs and nail hygiene behaviors were 5.15±0.58, 5.26±0.81, 3.69±0.96 and 5.03±0.98, respectively. Statistically significant relationships were detected in terms of participants’ clinical experiences with respect to behavioral and normative beliefs ( p <0.05 for all three belief categories). Participants working in general dental hospitals and dental university hospitals demonstrated the highest scores for behavioral, normative and control beliefs ( p <0.05). Participants working in dental clinics reported the highest “nail art” experience rates in the last two years (45.5%) and at the time of the survey (15.7%; p <0.05). Nail hygiene behaviors were more likely to be observed in individuals with stronger behavioral and stronger normative beliefs ( p <0.05). Conclusions: More specific infection control guidelines for “nail art” among dental workers should be established and promoted, so that both patients and dental workers can interact in a safe environment.

    Abstract PDF
    Objectives: The purpose of this study was to provide basic data for gingivitis management programs by dental hygienists by evaluating the effect of oral health education, oil pulling, and professional toothbrushing on gingivitis. Methods: A total of 38 subjects were divided into three groups: control group (12 subjects), experimental group 1 (13 subjects), and experimental group 2 (13 subjects). The control and experimental groups were instructed to brush using the rotating method. Distilled water was provided to the control group after training. Coconut oil was provided every morning for about 10 minutes. In the experimental group 2, a professional brushing method was used at each visit. Results: There were no significant differences in oral health among the three groups, and there was homology between patient hygiene performance (PHP) index ( p =0.144) and bleeding rate ( p =0.213). The PHP index showed a significant interaction between the group and measurement time. The control and experimental groups showed changes in the PHP index with time (F=3.711; p =0.013). The bleeding rate showed a significant interaction between the group and measurement period. The control and experimental groups showed changes in the bleeding rate with time (F=6.707; p <0.001). Conclusions: Oral health education, professional toothbrushing, and oil pulling specialists in oral care of gingivitis were effective in managing gingivitis. It is necessary to educate people on self-management methods for oral health promotion using gingivitis management programs by dental hygienists.

    Abstract PDF
    Objectives: This study was conducted to examine the subjects’ oral health status and changes in the oral environment after mouthwash with effervescent Vitamin C and its intake and to understand the impact on changes in the number of bacteria causing periodontal diseases in the oral cavity based on the oral health status and oral environmental condition. Methods: After obtaining approval from the Institutional Review Board of DーUniversity, 45 people (24 in an experimental group and 21 in a control group) who participated in the oral health program were selected, among visitors of the Clinical Dental Hygienics Laboratory of D. University in B. Results: Based on the subjects’ periodontal health status, the number of bacteria causing periodontal diseases in the oral cavity decreased in both experimental and control groups before and after the experiment. However, in the experimental group, it was significant when the Bleeding on Probing(BOP) level was below average, and Calculus index(CAL) was above average, in Aggregatibacter actinomycetemcomitans and the red complex. It was also significant when CAL was above average in the orange complex in the control group. Regarding bacterial changes in periodontal diseases based on the subjects’ oral environmental condition, there was a significant change in the Adenosine Tri Phosphate (ATP : intraoral contaminants test) test in the oral cavity in A. actinomycetemcomitans and the red complex in the experimental group and in the O’Leary index in the control group. Further, there was a significant change in the orange complex in the ATP test in the experimental group. Conclusions: A comprehensive analysis of the results revealed that the oral health care program for dental hygiene decreased the number of bacteria causing periodontal diseases in the oral cavity in both experimental and control groups.

    Abstract PDF
    Objectives: In this study, by a professional who provides medical services by gauging the level of personality recognition among dental hygienists, the basic data is provided to suggest the need for personality education in dental hygienists' education. Methods: A questionnaire survey was conducted with the members attending conservative education in 2018, and the results of the analysis of the total of 348 members were as follows. Results: The average age of the participants was 31.6 years, and their average career duration was 9.4 years. The total personality score was 3.74 points. The highest score was 4.10 points for conscience, and the lowest score was 2.98 points for habit. In terms of differences between general characteristics and personality domains, the personality perception score was statistically significantly higher for hygienists who were married than for those with a higher education level and working at a higher hospital level. There was a statistically significant positive correlation between the personality domains and the highest competence domain (r=0.790) in relation to total personality. The higher the competency, the higher the total score. Conclusions: Personality is not a part of being formed in the short term. It should be recognized that it is important to recognize the importance of personality in the dental hygiene education curriculum and to provide opportunities to develop personality through systematic programs.

    KyeongHee Lee | Yoon Young Choi | 2019, 19(3) | pp.409~419 | number of Cited : 0
    Abstract PDF
    Objectives: The purpose of this study was to analyze the factors affecting antibiotic prescription in dental outpatients. Methods: The present study was conducted using data from the National Health Insurance Service – National Sample Cohort. We analyzed prescriptions issued in the dental outpatient department in 2015, for adults over 19 years of age. Antibiotic prescription rates and mean prescription days were analyzed by sex, age, insurance type, presence of diabetes mellitus and hypertension, season in treatment, type of dental institution, and location of dental institution. Multivariate logistic regression was also performed to analyze the factors affecting antibiotic prescription in dental outpatients. Results: A total of 257,038 prescriptions were analyzed. The mean prescription days of antibiotics in dental outpatients were 3.04±1.08 days, and the prescription rate was 93.0%. Two variables (presence of diabetes mellitus and insurance type) were excluded from the multivariate logistic regression analysis model because they did not significantly affect antibiotic prescription. The possibility of antibiotic prescription was higher in men ≥61 years of age and those with hypertension. Furthermore, antibiotics were most frequently prescribed in dental clinics rather than dental hospitals, and more frequently in Busan compared to other areas ( p <0.001). Conclusions: Several factors were determined to affect antibiotic prescription, and detailed guidelines for consistent antibiotic prescription are needed.

    Abstract PDF
    Objectives: The purpose of this study was to compare the dental treatment needs of workers depending on their shifts and working patterns. Methods: Only workers aged 15 or older according to the 6th Korea National Health and Nutrition Examination Survey (2013–2015) were considered eligible. A total of 9,092 people who responded to health surveys and completed oral examinations and interviews were selected for the study. Statistical analysis was carried out by the complex samples general linear model. Results: As the daytime workers’ age increased, the requirement for restorative treatment decreased. In contrast, the requirement for tooth extraction caused by dental caries and periodontal disease increased. As the evening shift workers’ age increased, the requirement for restorative treatment decreased. In the case of shift workers, the requirement for restorative treatment was lowest in those aged 50–64 years and highest in those aged 30–49 years. In the case of smokers; the daytime workers required a higher amount of restorative treatment, pulpal treatment, and tooth extraction due to dental caries and periodontal disease; the night shift workers required a higher amount of restorative treatment; and the shift workers required a higher amount of tooth extraction caused by periodontal disease. The results of comparing the dental treatment needs depending on working patterns were: the need for restorative treatment was higher in night shift workers (0.377) than in shift workers (0.245); the requirement for pulpal and restorative treatment was higher in daytime workers (0.055) than in night shift workers (0.010); requirement for tooth extraction due to periodontal disease was higher in night shift workers (0.060) than in evening shift workers (0.012). Conclusions: There are differences in dental treatment needs depending on the workers’ working patterns. Collective oral health care is needed at workplaces to promote the workers’ oral health.

    Sun-Mi Lee | 권홍민 | 김창희 | 2019, 19(3) | pp.437~448 | number of Cited : 0
    Abstract PDF
    Objectives: The purpose of this study was to suggest an effective instruction method for dental hygiene students by determining the degree of importance and satisfaction that they attach to the courses. Methods: Data obtained from a survey that was conducted on 654 dental hygiene students were analyzed. Statistical Package for the Social Sciences version 23.0 was used for the statistical analysis. A paired t -test was conducted to detect the differences between the degree of importance that the respondents attached to the courses and the degree of satisfaction they achieved. A comparative analysis of the two was performed using the IPA analysis. Results: Regarding the items, the respondents found the environment most important, followed by the content, method, perspective, and assessment. Regarding satisfaction, they were most satisfied with the environment, followed by the perspective, method, content, and assessment. Regarding the importance of ideal teaching, the respondents gave the highest priority to ‘a class in which the core content is summarized, emphasized, and explained.’ The satisfaction was the highest toward ‘PowerPoint-based classes in which the core content is well-organized.’ Based on the results of the IPA analysis, the respondents regarded 16 items as requiring maintenance and continuous efforts, 12 items as low priority, and 4 items as requiring excessive efforts and timely improvement. Conclusions: An ideal class requires the instructor to utilize various teaching methods that would enable the students to comprehend the detailed teaching content and elicit active interaction and feedback from the students through easy-to-understand lectures that are appropriate for students.
