Introduction: The legal duties of Korean dental hygienists are different from the actual tasks. These factors cause dental hygienists to experience work stress. Therefore, it is necessary to investigate what tasks the dental hygienist expects to perform. Methods: This study examined the perception of dental hygienists' work on 158 prospective graduates of the 3rd-year and 4th-year course of dental hygiene. The questionnaire about the dental hygienist's duties was prepared based on the job description of dental hygienists by the Korea Health Personnel Licensing Examination Institute. Results: More than 84% said that all of the work in the second job description was possible as dental hygienists. subjects responded that the following items were not dental hygienists' duties: treatment plan based on medical history and dental history, treatment plan based on an intraoral and extraoral examination, treatment plan based on the results of teeth and periodontal examination, analysis of oral health data in community, planning of oral health promotion in community, planing of water fluoridation, reading of radiography, root planing, physical treatment on head and neck, using an ultrasonic device on head and neck, dealing with laser devices, making a temporary crown, suture and stitch-out, and intramuscular injection. Conclusions: Most graduates of dental hygiene departments have recognized that the tasks described in the second job description are dental hygienists' work; therefore, it is necessary to improve the gap between expected work and legal work.

Objectives: The purpose of the study is to investigate the awareness and practice of dental unit waterline management in dental hygienist. Methods: A self-reported questionnaire was completed by 377 dental hygienists in Seoul and Gyeonggido from March 2 to April 30, 2015. The data were collected by direct visit and informed consent was received after explanation of the study. The questionnaire consisted of general characteristics of the subjects, awareness of dental waterline, practice of dental waterline, and implementation of dental waterline disinfection. Data were analyzed using SPSS 12.0 program. Results: There was a significant correlation between the dental unit waterline disinfection and the appropriateness of the water used for dental treatment(p<0.01, p<0.001). The handpiece was the most commonly used device before treatment and the majority of the subjects answered that they didn't take water out of ultrasonic scaler and air-water syringe on a daily basis. Conclusions: The majority of the dental hygienists did not know the right understanding and proper practice of dental unit waterline management. To reduce the dental device contamination, the continuing education of waterline management should be done for the dental hygienists.

Objectives: The study was conducted to evaluate the effects of the students majoring in dental hygiene on their oral health beliefs and oral health behavior. Methods: The survey was conducted using selfadministered questionnaires targeting 619 female students majoring in dental hygiene at three Universities in k and J province. The stronger health oral belief means higher score in susceptibility, severity, benefit and salience, but the higher score in barrier means stronger recognition in obstacle. Results: There was significant correlation between susceptibility and experience of not-treated oral disease (OR [odds ratio] 2.40; 95% CI [confidence interval] 1.73-3.34)' and 'dental caries (OR 2.36; 95% CI 1.25-4.45)'. Benefit had significant correlation with 'visiting dental clinic (OR 1.58; 95% CI 1.14-2.19)'. Salience had significant correlation with 'experience of not-treated oral disease (OR 0.70; 95% CI 0.52-0.94)'. Barrier had significant correlation with 'visiting dental clinic (OR 0.73; 95% CI 0.56-0.95)' and 'removing oral plaque (OR 0.71; 95% CI 0.52-0.95)'. There was no significant correlation between oral health belief and 'using of oral hygiene device' or 'regular tooth brushing'. Conclusions: Diverse oral health behaviors were affected by susceptibility, benefit, salience and barrier in oral health belief. The programs for oral health education and preventing oral disease should be prepared to change oral health belief to promote the oral health systematically based on the results of this study.

The purpose of this study was to investigate the antibacterial effect of the low temperature atmospheric plasma device with needle tip designed for easy approach to the oral cavity and root canal against Streptococcus mutans, Enterococcus faecalis and Candida albicans. The antibacterial activities evaluated by measuring clear zone of agar plate smeared with each bacteria after plasma treatment. To quantify antibacterial effects, dilution plate method was used. In addition, scanning electron microscope (SEM) was used for observation of changes in bacterial morphology. As treatment time of plasma increased, the clear zone was enlarged. The death rate was more than 99%. The SEM results showed that the globular shape of bacteria was distorted. These results suggest that needle tip plasma could be an innovative device for prevention of dental caries, and treatment of apical infection and soft tissue diseases.
