Objectives: The study was to promote patient safety by analyzing the effect of dental hygienist's perception of patient safety culture on infection control activities. Methods: The study is based on a survey of 377 dental hygienists in total working in dental settings. The questionnaire consisted of 119 questions, including 34 questions on perception of patient safety culture, and 85 questions on infection control activities. Hierarchical regression analysis was used to examine the relationship between the perception of patient safety culture and infection control activities. The data was analyzed using the SPSS version 20.0, and p<0.05 was adopted to decide on significance. Results: The longer dental hygienists have worked n the dental settings, the more active they become in infection control activities. Among the different types of dental care settings, general (university) hospitals had the largest number of infection control activities, followed by dental clinics, and network dental clinics, in descending order. The dental settings possessing a higher number of dental hygienists were found to conduct more infection control activities than other dental settings. In addition, it was found that when a dental setting adopts a patient safety policy across all the units in the hospital, more systems and procedures for patient safety tend to be established, and that stricter management response to error leads to improvement of infection control activities. Conclusions:In order to enhance infection control activities, infection control activity programs should develop and implement periodic reinforcement of infection control education. regular monitoring of infection control activities.

Korean dental hygienists perform more tasks in dental clinics than are described in the law. The purpose of this study was to investigate the actual work of Korean dental hygienists in dental clinics using an observational study design. Two dental hygienists observed and recorded the work performed in 1 day from the time of commencement to the time of leaving work by 18 dental hygienists working in the dental clinic in a single area. Data management, prevention of infection, counseling, calculus removal, radiography, assistance of fixed orthodontic treatment, assistance of fixed prosthetic treatment, and preparation for implant surgery were recorded. Among the tasks that take more than 1 min, the most time-consuming tasks were document management, infection control, consultation, calculus removal, preparation for implant surgery, assistance of orthodontic treatment, and assistance of fixed prosthetic treatment. Korean dental hygienists are performing various tasks, such as infection control, dental hospital/clinic management, oral disease prevention, and dental treatment assistants.

This study aims to help utilize the dental treatment institutions for the disabled and provide high quality of medical services in the future by identifying the satisfaction factors for the patients of the dental clinics for the disabled. As a study method, surveys were completed 200 patients who visited the dental hospital for the disabled. Among these, the surveys from 187 patients were statistically analyzed. The main findings of this study are as follow. Since the study showed that there were differences in the satisfaction factors between the disabled and non-disabled people, subsequent studies needs to be done to develop measuring tools to accurately accommodate the satisfaction factors of the disabled. In addition, as the low spatial accessibility in terms of distance and location was found in this study, more dental treatment institutions for the disabled are required. In the meantime, the survey results found that the most satisfactory aspect was the lower treatment cost compared to other clinics, and that the most important factor when choosing a clinic was also treatment. In addition, given the fact that the group that took a prosthetic treatment, which was non-insured treatment, showed higher satisfaction compared to the group that did not, it suggests that the economic burden plays an important role for the dental treatment of the disabled.

In accordance with Article 33(8) of the Korean Medical Law, it is stated that a medical person cannot open or operate a medical institution by borrowing the name of another medical person. However, the publicity of medical care is threatened by the recent illegal network dental clinics. The purpose of this study is to investigate the actual condition of illegal network dentistry and to analyze the cases and to find out the reason why the prohibition of double opening & operating of medical institution. As a result, the illegal network dental clinics treated less health care insurance treatment such as dental caries and periodontal treatment than general dental hospitals. In contrast, the rate of implementation of illegal network dentistry was high in endodontics treatment and extraction, which could lead to uninsured treatments such as crowns and implants. As a result of Supreme Court precedent analysis, it is concluded that illegal act is not only the opening of a medical institution by borrowing the name of other medical personnel, but also the duplicated operation which has the authority to make decision about management matters of medical institutions. The results of the patient's case survey also showed that excessive dental treatment due to such as dental staff incentive system. In conclusion, the illegal network dental clinics not only threatens the oral health of the public, but also causes leakage of health insurance premiums. In other words, the ban on opening and operating the multiple medical institution should be strictly applied as a strong protection device for protecting the patient in dental case.

This study was performed to investigate the mean life expectancy of dental prosthetic restorations. The author has examined 352 dental prosthesis clinically and radiologically, and decided the success(survival) and failure(mortality) of the dental prosthesis. The dental prosthesis which had been treated in the Seoul National University Dental Hospital, two private clinics in Seoul, one university dental hospital, and two private clinics in local province were included in this study. The survival analysis using product limit estimator was used and the mean life expectancy of each type of dental prosthesis was calculated. The results were as follows : 1. The life expectancies were 10.5 years in gold crown and bridge, 8.5 years in porcelain fused to metal crown and bridge, 8.3 years in nonprecious metal crown and bridge, 8.1 years in removal partial denture, and 7.7 years in full denture. 2. The causes of mortality were in the order of dental caries(24.6%), fracture of dental prosthesis(19.2%), periodontal problems(18.6%), chronic chewing difficulty and dysfunction due to dental prosthesis(15.0%), excessive exposure of abutments due to the marginal defect of dental prosthesis(14.4%), abnormal occlusion due to severe attrition of artificial teeth in dentures(3.0%), periapical problems(2.4%), perforation of dental prosthesis(1.8%), and loose contacts with neighboring tooth(1.2%). 3. Among survival cases, 66.5% showed normal chewing ability and 31.9% showed partial chewing ability. However, 1.6% of them complained loss of chewing ability. 4. Among failure cases, 6.6% showed normal chewing ability and 38.9% showed partial chewing ability. However, 54.5% of them complained loss of chewing ability.
