Priority setting in national health insurances in major advanced countries and the nation was investigated to draw the criteria for priority setting and suggest the most rational criteria for dental insurance so as to help secure the efficiency of medicare financing and individual's health right and also elevate medical consumers' satisfaction with health insurance. 1. Priorities in national health insurance are different from country to country, depending on the medical security systems, priority introducing conditions, and social environment, but have many common factors. 2. The priority setting criteria for national health insurance in those countries include the following in common: the efficiency, equity, and cost effect of treatment, emergency of treatment, consumption of expense, efficacy of treatment, patient's receptiveness, patient's demand, severity of disease, and patient's responsibility for the disease. 3. In oral diseases, severe diseases including oral cavity cancer are low in rate, and in-hospital treatments are few. From the above findings, it is suggested that dental insurance should establish discriminative criteria for priority setting by reflecting the aspects of dental diseases and system difference between dental and other health insurances and taking account of efficiency of treatment through prevention, cost effect, prevalence and incidence of generalized diseases, and individual's financing burden.

Medication-related osteonecrosis of the jaw (MRONJ) has recently associated to the increase in antiresorptive and anti-angiogenic drugs prescriptions in the treatment of oncologic and osteoporotic patients. The physiopathogenesis of MRONJ remains unclear and available treatments are unsatisfactory. Newer pharmacological treatments have shown good results, but are not curative and could have major side effects. At the same time as pharmacological treatments, mesenchymal stem cells (MSCs) have emerged as a promising therapeutic modality for tissue regeneration and repair. MSCs are multipotential non-hematopoietic progenitor cells capable to differentiating into multiple lineages of the mesenchyme. Bone marrow MSCs can differentiate into osteogenic cells and display immunological properties and secrete paracrine anti-inflammatory factors in damaged tissues. The immunomodulatory, reparative, and anti-inflammatory properties of bone marrow MSCs have been tested in a variety of animal models of MRONJ and applied in specific clinical settings. The aim of this review is to discuss critically the immunogenicity and immunomodulatory properties of MSCs, both in vitro and in vivo, the possible underlying mechanisms of their effects, and their potential clinical use as modulators of immune responses in MRONJ, and to identify clinical safety and recommendations for future research.

This study aims to discuss plans to improve the satisfaction level of dental services by understanding characters of beliefs about dental manpower and analyzing its related factors. Data were collected by structured questionnaire whose subjects consist of 1607 persons from 13 years old to 69 years old, who have ever experienced dental institution. Both univariate and biovariate analyses were employed to analyze level of dentist and dental hygienist's beliefs and its related factors and the results gained from the surveys and search are as follows. 1. Among the questions to measure dentist's beliefs, 'Respect for patients' was evaluated as the best, and the lowest items were 'not-hopeful explanation about prognosis of dental treatment', 'satisfactory explanation' and 'whether treatments are stopped by pains or not'. In addition, among questions to measure dental hygienist's beliefs, 'kindly welcome' and 'detailed explanations about medical directions' are the items evaluated as the best and 'notice of waiting time' marked the lowest evaluation. 2. The factors related to beliefs about dentists were age, ache experiences, dental fear, self-reported dental health status, frequence and primary purposes of the visits dental institutions, elapsed time from recently visited, present of favorite dental clinic to visit regularly. 3. The factors related to beliefs about dental hygienists were age, education, occupation, ache experiences, frequence and primary purposes of the visits dental institutions, periodic check of teeth, present of favorite dental clinic to visit regularly. 4. Direct painful, painful treatment experience under insufficient local anesthetic, indirect painful experience and dental fear were positively correlated. And the relationships were positive between ache experiences, dental fear and self-reported dental health status, but relationships were negative between ache experiences, dental fear and dentist! dental hygienist's beliefs.

With these changes in the environment of dental service, dental hygienists are suggested to change their roles to cope with the changes. Hygienists are putting forth many efforts to promote smooth and efficient dental treatments, and as a practical measure. As a part to cope with such changes. Korea Dental Hygienists Association(KDHA) has prepared the system of Specialized Dental Hygienist and put the system into enforcement through an affiliated organization, Korean Academy of Dental Hygiene. The purpose of this study is to investigate the specialized nurse system in our country's medical environment and the specialized dental hygienist systems in other countries as similar cases comparable to the specialized dental hygienist system in our country and present basic data for the establishment of specialized dental hygienist system. For this study, a survey of dental specialists, such as dentists, dental hygienists and nurses, and patients, has been conducted qualitatively through person-to-person depth interview. The interview questions were related to the need for a specialized dental hygienist system, educational programs, functions and roles, and issues that must be solved for establishment of the system. Based on the interview results, the following conclusions were derived. The specialized dental hygienist system must encourage dental hygienists to possess advanced abilities in clinical practices, present systematic and developmental directions in educational programs, and stimulate specialized dental hygienists to actively work as manager and supervisor, medical health service providers, educators, and researchers. Lastly, for issues that must be solved for the establishment of the system, the duties and jobs of specialized dental hygienists must be defined more concretely, which must be acknowledged by people working in related occupations, citizens and the government. Furthermore, we need to examine the scope of duties of dental hygienists and enact laws and systems to protect the scope. These roles will lead dental hygienists to lay the foundation that allow them to make enthusiastic activities as an oral hygienist and clinician as well as show the way how to act as an educator, a researcher, a manager and an administrator.

With the explosive increase of esthetic demands by patients, many dental materials for the esthetic restoration have been introduced. Recently, zirconia based restorations are using for the cases of single crown, bridges, implant prostheses etc. Zirconia have superior mechanical properties and biocompatibility. Owing to the properties of high strength, zirconia has to be manufactured by CAD/CAM system. Dental CAD/CAM system is a futuristic treatment and technical system which makes it possible to produce the precision and uniform prosthesis and also standardize the treatments. This article introduces the characteristics of zirconia, fabrication procedure using CAD/CAM system and procedure for the cementation of zirconia based restoration.

Patients with severe gag reflex (SGR) have difficulty getting the treatment they require in local clinics, and many tend to postpone the start of their treatment. To address this problem, dentists have used behavioral techniques and/or pharmacological techniques for treatment. Among the pharmacological methods available, propofol IV sedation is preferred over general anesthesia because it is a simpler procedure. Propofol in combination with remifentanil is characterized by stable sedative effects and quick recovery, leading to a deep sedation. Remifentanil acts to reduce the pain caused by lipid-soluble propofol on injection. The synergistic effects of propofol-remifentanil include reduction in the total amount of drug required to achieve a desired sedation level and anti-emetic effects. In this case report, we outline how the use of propofol-remifentanil IV sedation enabled us to successfully complete a wide range of dental treatments in a patient with SGR.
