Background: Recently, a piezoelectric ultrasonic scaler based on a feedback control mechanism was introduced for pain relief. This study aimed to investigate the effects of a new ultrasonic scaler in reducing pain and discomfort in adults. Methods: A newly introduced ultrasonic scaler (Master 700^®) was used as the test device and a conventional ultrasonic scaler device (PIEZON^®) was used as the control device. Forty-one healthy adults visited the dental clinic for dental scaling but did not undergo scaling or periodontal treatment within 6 months. Intraoral examinations were performed before scaling and 3 months later; before scaling, both devices were randomly assigned on the left or right side of each dentition (split-mouth model) and scaling was performed by a registered dental hygienist. The levels of pain and discomfort during scaling were evaluated subjectively and objectively using the visual analog scale (VAS) and physiological monitoring of the heart rate (HR), respectively. Time was measured for each device. Results: All clinical indicators, except bleeding on probing, significantly improved with both devices. The treatment times were 7 minutes, 13 minutes (control) and 6 minutes, 59 minutes (test). VAS scores for pain were 4.89±2.12 (control) and 4.58±2.77 (test) points out of 10; for noise, these were 4.68±2.33 (control) and 4.55±2.55 (test), and for vibration, the values were 4.26±2.0 (control) and 4.18±2.48 (test). HR averages were 72.34±3.39 (control) and 75.97±9.78 (test) beats/min. No statistically significant differences were observed between the devices. Conclusion:The pain, discomfort levels, and scaling time of the new piezoelectric ultrasonic scaler did not differ from those of the conventional device. Further research and development are necessary for more prominent pain-relief effects of scaling devices.

Background: The importance of infection with COVID-19 is being emphasized in dentistry with high risks such as aerosols. The purpose of this study is to investigate the knowledge and practice of infection control, stress and coping, and turnover of dental hygienists. Methods: Questionnaire was conducted knowledge and practice of infection control, occupational stress and coping, turnover. Survey data was investigated about 149 dental hygienists from February to March 2021 Data were analyzed t-test, ANOVA, Pearson's correlation using statistical programs of PASW Statistics ver. 21.0. Results: Regarding occupational stress, relationship conflict was higher in the group with less than 2 years of experience (p<0.05). Job anxiety, organizational system, inadequate compensation, and workplace culture were highly surveyed in the 3 to 5 year of experience. The group with more than 6 years of experience had the highest perception of lack of job autonomy (p<0.05). The group with higher knowledge of infection control had lower mean inappropriate rewards and stress (p<0.05). The group with high infection control performance had a lower average in items such as job instability, organizational system, inadequate compensation, workplace culture, and stress. And problem-focused coping ability was found to be high (p<0.05). Infection control knowledge and performance were positively correlated (r=0.251, p<0.01), infection control practice and stress were negatively correlated (r=-0.264, p<0.01), and stress and emotional coping were positively correlated (r=0.367, p<0.01). Stress was positively correlated with turnover rate (r=0.549, p<0.01). Conclusion: Infection control training was required to reduce occupational stress. Occupational stress was highly correlated with turnover, a holistic and systemic organizational operation and improvement of the quality of medical care were required to reduce stress.

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.

Purpose: This study was conducted to test the effect of a scenario based hand hygiene education program on hand hygiene knowledge, hand hygiene perception, hand hygiene compliance and hand hygiene method in nursing students. Methods: A non-equivalent control group, non-synchronized quasi-experimental design was used. Forty five nursing students participated in the study with 22 in the experimental group and 23 in the control group. Data were analyzed using descriptive statistics, ${\chi}^2-test$, t-test, and repeated measures of ANOVA. Results: There were significant increases in hand hygiene knowledge (t=-4.28, p<.001) and accuracy of the hand hygiene method by week (F=7.33, p<.001). However, hand hygiene perception (t=-1.67, p=.102) and hand hygiene compliance rate (F=7.33, p=.405) were not significantly changed. Conclusion: The effects of the scenario based hand hygiene education program provided in this study were excellent, compared to the other hand hygiene education programs. Moreover, as a result of investigating the education effects through direct observation for 4 weeks, appropriate feedback was offered in the third week, and it was found that maintaining the effect was necessary. However, the current status of hand hygiene compliance and accuracy of methods for ensuring hand hygiene need to be studied further.

The purpose of this study was to examine the influence of the self-control of dental hygiene students on their stress and stress-coping style. The subjects in this study were dental hygiene students who were selected by convenience sampling from three different colleges. After data were gathered, the answer sheets from 561 respondents were analyzed. The findings of the study were as follows: 1. Concerning the level of self-control, the dental hygiene students got a mean of 3.22. As to self-control by grade, the juniors got the highest scores of 3.27 (p<0.05), and those who were under heavier stress were poorer at self-control (p<0.05). 2. In regard to stress-coping style, they got a mean of 3.28 and 3.34 in active coping and passive coping respectively. Passive coping was more prevailing, and the students whose economic status was higher made more use of active coping styles (p<0.001). There were statistically significant differences in active coping styles according to stress level (p<0.01) and the effect of stress on health (p<0.05). 3. Better self-control led to more frequent use of active coping styles. The above-mentioned findings imply that self-control is one of factors to affect stress coping. Therefore the development of counseling programs is required to step up the improvement of self-control.
