Objectives : The purpose of this study was to investigate the association factors of infection control practice based on health belief model in the dental hygienists in dental clinics. Methods : A self-reported questionnaire was filled out by 278 dental hygienists in 160 dental clinics in Gwangju by a proportional stratified sampling method from September 13 to October 7, 2013. Data were analyzed by t-test, ANOVA, correlation analysis, and multiple regression analysis using SPSS version 12.0. Results : In multiple regression analysis, practice scores were significantly higher in aged dental hygienists and those who took infectious disease history from the patients before treatment. With regard to health belief model, perceived barrier was negatively associated with the practice(${\beta}$=-.16, p<.001), importance of infection control in hand hygiene(${\beta}$=.14, p=.026), and use of personal protective equipment(${\beta}$=.17, p=.043). The intention of action was positively associated with the practice(${\beta}$=.13, p=.002). Conclusions : This study will provide the basic evidence for the quality improvement of infection control and prevention. So the dental hygienists will be able to put into practice in infection control management.

Objectives: To investigate the real-world re-use of disposable dental supplies (DDS) in dental offices and assess the relationship between general characteristics of dental hygienists and reuse of DDS, with respect to infection control characteristics. Methods: A questionnaire was administered to 277 dental hygienists to assess their general characteristics, awareness of infection control/DDS management, and re-use of DDS. Nine DDS were categorized into the following categories based on their purpose: Critical, Semicritical, Noncritical, and Personal protective equipment (PPE). The association between general characteristics of dental hygienists and re-use of DDS, with respect to infection control characteristics, was assessed using the chi-squared test. Results: All 9 DDS were re-used to different extents. The highest reuse rate of supplies were for masks (64.6%), prophylaxis cups (61.0%) and plastic saliva ejectors (30.0%). Overall, 89.5% of the participants re-used DDS; subgroup analysis showed the following proportions of specific DDS re-use: PPE 66.4%; Semicritical DDS 63.9%; Noncritical DDS 19.5%; and Critical DDS 1.8%. Based on the type of clinic, the rate of re-use was higher in dental clinics than dental hospitals. Thus, the re-use of DDS may be caused by inappropriate or nonexistent guidelines or habitual practice, rather than the awareness or attitude of dental hygienists. Conclusions: In order to ensure a safe environment within the dental clinic, DDS classifications must be clearly outlined in the dental infection control guidelines; moreover, additional studies are needed regarding the regulations for DDS re-use and disposal.

The purpose of this study was to examine the degree of infection control implemented at dental offices and factors affecting it in an attempt to help promote the health of dental health care workers. The subjects in this study were 180 medical personnels who worked at dental offices in the region of South Jeolla Province. A self-administered survey was conducted from April 1 to May 30, 2008, and the collected data were analyzed. The findings of the study were as follows: 1. As for the implementation of infection control at the dental offices, what the health care workers investigated did the most was post-treatment hand washing(95.0), a constant separation of infectious wastes(94.4), wearing rubber gloves all the time during medical instrument cleansing(92.8) and pre-treatment hand washing(91.7). 2. In regard to the implementation of infection control at the dental offices, what the dental personnels did the least was drying their hands with air(5.0), wearing goggles in times of treatment(23.3), receiving regular education on infection control(26.7) and putting sterilizers to a performance test on a regular basis(43.9). 3. The dental health care workers were significantly different according to age in the management of contagious diseases(p=0.005). Their career made a significant difference to the management of contagious diseases(p=0.000) and instrument cleansing/sterilization(p=0.043). The service area made a significant difference to wearing and managing personal protective clothes (p=0.040) and waste management(p=0.040). 4. Concerning the relationship between the acquisition of dental hygienist certificate and the practice of infection control, whether the dental health care workers were certified or not made no significant difference to that. 5. As to the correlation among the factors affecting the prevention and management of contagious diseases, there was a positive correlation among hand washing(r=0.379), wearing and managing personal protective clothes(r=0.349), instrument cleansing/sterilization(r=0.323) and waste management(r=0.388). All the factors made a statistically significant difference to the prevention and management of contagious diseases(p<0.01).

Objectives : This study was conducted to investigate the actual state of dental hygienist's behavior for infection control during dental practice and radiologic examination and to evaluate the dental hygienist's awareness of the importance of infection control in dental office. Methods : A survey on 218 dental hygienists was carried out. The respondents to complete a questionnaire were the dental hygienists who were in dental office on Gwang-ju area or attended complementary training conducted by the Seoul Branch of Korean Dental Hygienists Association in April 2010. The data were collected and analyzed with $x^2$ test, t-test, ANOVA using SPSS program. Results : The ratios of educational experience for infection control in dental practice and radiologic examination room accounted for 87.6% and 30.3% respectively. Behavior degree of mask-wearing in the dental practice and radiologic examination room were $4.60{\pm}0.70$ and $3.77{\pm}1.09$ respectively. Behavior degree of glove-wearing in the dental practice and radiologic examination room were $4.40{\pm}0.91$ and $3.68{\pm}1.17$ respectively. In case of the relation between educational experience and behavior degree in mask-wearing or glove-wearing, there was no significant difference in the performance of mask or glove wearing during dental practice, and mask-wearing during radiologic examination. However, there was a significant difference (p<0.05) in the performance of glove-wearing during radiologic examination, which revealed that behavior degree between the respondents having educational experience and the others no having it were $3.92{\pm}1.19$ and $3.58{\pm}1.14$ respectively. The surface disinfection control for radiation and protective equipments used in radiologic examination room was done by occasional needs without premeditated schedules. Conclusions : The result of this study shows lower behavior degree during radiologic examination compared with one during dental practice.

치과 진료의 특성 상 치과 진료 인력의 손이 환자의 입안에 직접 접촉하는 상황이 빈번하게 발생한다. 또한 고속 절삭 도구와 날카로운 기구, 주사바늘을 일상적으로 사용하기 때문에 출혈이 동반되는 경우가 대부분이므로 교차 감염의 가능성은 매우 높다. 진료실에서의 병원체는 오염된 인상체, 보철물을 통해 치과 진료실 뿐만 아니라 치과 기공실에도 전파될 수 있다. 치과 진료 인력(치과의사, 치과위생사, 치과기공사)은 모든 환자가 교차 감염의 위험성이 있음을 인식하고 적절한 감염 관리를 통해 감염이 전파되는 것을 방지할 수 있도록 노력해야 한다. 본 논문에서는 문헌 고찰을 통하여 치과용 인상체의 소독 방법과 화학적 소독제에 대하여 고찰해 보고, 임상에서 효율적으로 적용할 수 있는 인상체의 감염 관리 방법에 대하여 알아보고자 하였다.

Objectives: The purpose of the study was to investigate the perception and practice of the infection control by empowerment in the dental hygienists. Methods: A self-reported questionnaire was filled out by 200 dental hygienists in Gyeongbuk from January 3 to February 20, 2013. Data were analyzed by SPSS 12.0 program. The instrument of impowerment was adapted from Spreitzer and consisted of 12 questions including meaning(4 questions), competency(4 questions), self-decision(4 questions), and impact(4 questions). Impowerment was score by Likert 5 scale and higher score means higher impowerment. The instrument for hand washing recognition and practice was adapted from Kim and consisted of hand washing(5 questions), personal protective clothing management(5 questions), contaminated appliance management(3 questions), sterilization(3 questions), and infection control environment(8 questions). The empowerment instrument was score by Likert 5 scale and the mean was 3.83 points. Based on 3.83, infection control recognition and practice were divided into upper group and lower group. Cronbach alpha was 0.951 in empowerment, 0.931 in recognition, and 0.924 in practice in the study. Results: Based on the average points of 3.83, the groups were divided into two groups including upper group and lower group. The upper group showed higher score in hand washing than the lower group. In the protective clothing management, the upper group changed the mask at one-hour interval(p<0.001). Conclusions: In the viewpoint of empowerment, it had a significant influence on the perception and practice of the dental infection control in the dental hygienists.
