Background: This study was conducted to determine the level of job satisfaction and patient safety cultural activities for dental hygienists and to determine the relationship between job satisfaction and patient safety cultural activities. Methods: A survey was conducted on 214 dental hygienists, and data from the final 180 were analyzed. Job satisfaction consisted of a total of 20 questions, and patient safety cultural activities included a total of 25 questions. The survey was conducted on a 5-point scale. Results: The average job satisfaction score of the study subjects was 3.44 points. Among patient safety cultural activities, infection control had the highest average score (4.12 points) and radiation safety management had the lowest average score (3.10 points). Patients with less than 3 years of clinical experience (4.01 points) had higher patient safety culture activity scores than those with 3 to 10 years of clinical experience (3.72 points) and those with more than 10 years of clinical experience (3.69 points). The level of patient safety cultural activities was statistically significantly higher as age, less clinical experience, and job satisfaction increased (p<0.05). Conclusion: In the case of dental hygienists, patient safety cultural activities must be carried out throughout the entire work, so an active will to practice patient safety cultural activities is necessary. In order to improve the performance of patient safety cultural activities, it is necessary to adjust the workload of dental hygienists to improve job satisfaction and create a work environment in which they can focus on patient safety cultural activities.

This study was conducted to understand the degree of personality and interpersonal relationships among dental hygiene students. The survey was conducted from April 1, 2021 to June 30, 2021. As a result of the study, personality was 3.42 points and interpersonal relationships were 3.46 points. In general, there was a statistically significant difference in both personality and interpersonal subdomains in interpersonal satisfaction and college life satisfaction (p<.05, p<.001). The more experience they had in clinical practice, the lower their scores for friendship and professorship among interpersonal relationships. Among the sub-domains of personality, morality and sociality were analyzed as having the highest positive correlation (r=.674), and in interpersonal relationships, the relationship between friends and professors was analyzed as high (r=.606). Therefore, for the holistic growth of dental hygiene students as preliminary dental hygienists and their adaptation to the dental care field, a long-term strategy and continuous educational approach are needed at the university for cultivating character and interpersonal relationships, which are the basics. In addition, various programs related to the duties of dental hygienists should be developed and methods to be applied should be sought.

This study was conducted to investigate the types and methods of dental impression materials used in dental clinics in south Korea, the questionnaire was surveyed by a self-administered method for one dentist in a one dental clinic, the collected data were statistically analyzed using SPSS 20. The most frequently used addition silicone impression materials were used in most dental treatment. It was confirmed that the method of taking impression materials having different flow properties(light body and heavy body) was most preferred at one time, also, the implant impression taking method was the most preferred for two rubber impression materials with different flow properties, both direct and indirect. There were statistically significant differences in age and clinical experience between the methods of impression taking of casting restorations and prosthetic according to general characteristics. These results are expected to be helpful for the development of theoretical and practical work based on the basic data for impression material development and research and the preference of impression materials required for dental professional in clinical practice.

Purpose: The purpose of this study was to provide basic data of oral health policy and effective nonsmoking educational the basic data comparing the subjective oral health recognition and tooth brushing pattern by smoking whether or not, the subjects were adults to visit dental clinic. Methods: The subjects were a total of about 245 adults visited dental clinics in Busan metropolitan city and Gyeongnam province some areas. The datas were collected from December 17, 2012 to February 17, 2013. Data analyses were done with SPSS program through frequency analysis and chi-square test. Results: The tooth brushing pattern of non-smokers were more brushing after meals and snacks, and then brushing within three minutes before bedtime and brushing with more than 3 minutes, brushing with rotating method is pretty more, smokers were not brushing after the meal, a snack, and then within 3 minutes before going to bed without brushing, more than three minutes brushing with rotation method. Subjective oral health status of non-smokers, the more awareness is pretty healthy, but smokers were the more unhealthy side, the greater the smoking amount among smokers subjective oral health were recognized as a bad side. Conclusion: It was necessary to recognize subjective oral health status and to provide a way to practice corrective brushing pattern according to smoking or not and smoking amount. Subjective oral health awareness and brushing pattern directly related to the smoking or not and smoking amounts of the subject, so when dental care, it should be followed to recognize exactly what to give oral health status of subjects and provide a way of effective oral health management in order to improve the oral health and quality of life.

Background: The purpose of this study was to identify the connection between handwashing and toothbrushing, focusing on eating habits, and to verify whether eating habits can be used as an action cue for forming health habits. Methods: This was a cross-sectional study using secondary data from the 2019 community health survey. The participants included 229,099 adults aged 19 years or older, representative of the South Korean people. We employed two dependent variables: one was washing hands, and the other was brushing teeth. Eating habits was a major independent variable. Socioeconomic variables, such as age, gender, income, occupation, economic activity, education, and residence were adjusted as confounders. Multivariate logistic regression was performed to calculate adjusted odds ratio and 95% confidence intervals. Results: Most of the participants had good health behaviors: those who wash their hands and brush their teeth were each approximately 80%. Our finding indicated that brushing teeth and washing hands can be connected with eating habits. After adjusting for confounders, it was found that people who wash their hands before meals (compared to those who did not wash their hands before meals) had a higher toothbrushing rate after meals (i.e., socioeconomic status) (Adjusted Odds Ratio: 2.0, Confidence Intervals: 1.9 to 2.1). Conclusion: Those who practice either washing hands before meals or brushing teeth after meals were found to have a connection between washing hands and brushing teeth based on the results of practicing other health behaviors. This implies that eating habits can be connected as a behavior cue to promote health habits, such as washing hands before meals and brushing teeth after meals.

Objectives: The purpose of the study was to analyze the association between indirect vision skills and neck, shoulder, and back pain in dental hygienists. Methods: This cross-sectional study included 85 dental hygienists working full-time at dental clinics. A survey was performed for musculoskeletal symptoms in the neck, shoulders, and back of the subjects. The O'Connor tweezer dexterity test was performed using a mirror to evaluate their indirect vision skills. For statistical analyses, the t-test and one-way analysis of variance were performed. Results: The neck was the most common region of musculoskeletal pain (89.4%). The most intense pain was experienced in the neck (70.6%) and right shoulder (60.0%). Neck pain (20.0%) caused the most interference with clinical practice. Indirect vision skills were lower in the group with severe pain in the left shoulder or with high interference in work due to the left shoulder pain (p=0.026 and p= 0.017, respectively) or right shoulder pain (p=0.004). Conclusions: In this study, neck pain was a major musculoskeletal symptom among dental hygienists, and poor indirect vision skills were associated with the development of shoulder pain. Therefore, to prevent such musculoskeletal symptoms, dental hygienists should become proficient in indirect visualization, which enables a balanced and neutral posture.

A dental treatment room is always exposed to diverse kinds of pathogenic bacteria, and may be a mediating place of cross-infection given being contaminated the interior of a room through several routes in the form of patient's secretion and aerosol. The main agent of preventing cross-infection is a dental hygienist in the dental treatment and the dental treatment room where are scattered about a risk of cross-infection. A dental hygienist needs to have right recognition on infection control before being active as a clinical expert. This infection-control recognition level is influenced from the clinical practice. Accordingly, to survey recognition of infection control, a self-administered questionnaire research was conducted targeting 314 students who are fixed the clinical practice as regular subject in the junior course out of curriculum for the Department of Dental Hygiene at some of 4-year universities. Data collection was performed from December 9, 2011 to February 22, 2012. Except 11 copies of questionnaire with insincere response among the collected materials, 303 copies were finally analyzed by using SPSS WIN 20.0. The following conclusions were obtained. In the infection disease section, both on and off campus showed 4.89 points from 'the importance of recognizing the infections prevention', 4.65 points from 'recognizing the compulsory preventative injection for hepatitis type B', 4.77 points from 'recognizing the necessity of the preventative injection for hepatitis type B', 4.71 points from 'whether practice the prevention in reality or not', and 4.76 points from 'the educational helps to the prevention'. In other words, the section recorded the highest and meaningful points. It is considered to be needed the development in systematic and diverse infection-control educational programs and the differentiated education depending on school year for dental hygiene students.

Background: As a restorative material used to treat dental caries, the light-curing type resin is widely used, but it has the disadvantage of polymerization shrinkage. The Bulk-Fill composite resin was developed to solve these shortcomings, but the existing research mainly focused on comparing the physical properties of a composite resin and a Bulk-Fill resin. A study on the light curing time and distance of the Bulk-Fill resin itself tend to be lacking. Methods: This study compares the surface microhardness of specimens prepared by varying the light curing time and distance of smart dentin replacement (SDR) as a flowable Bulk-Fill resin and Tetric N-ceram as a packable Bulk-Fill resin, and confirms the polymerization time and distance that becomes the optimum hardness. To determine the hardness of the specimen, it was measured using the Vickers Hardness Number (Matsuzawa MMT-X, Japan). Results: In SDR, the surface microhardness decreased as the distance increased in all time groups in the change distance from the curing tip. In the change of light curing time with respect to the distance from curing tip, the surface microhardness increased as the time increased. In Tetric N-ceram, the surface microharness showed no significant difference in the change of the distance of curing tip in the group of 20 and 60 second. But in the group of 10 and 40 seconds, decreased as the distance increased. The surface microharness increased as the light curing time increased in all distance groups. Conclusion: When using SDR and Tetric N-ceram in clinical practice, it is considered that as the distance from the polymerization reactor tip increases, a longer light curing time than the polymerization time recommended by the manufacturer is required.
