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.

With change in the pattern of disease occurrence and increase in the interest in health, efforts to assess the health status on patients covering their subjective awareness at the same time as clinical and objective evaluation on health are continued. To measure health-related quality of life can be one of these efforts. This study was performed to evaluate the relevance of the quality of overall health-related-life and oral health condition. Also the second year (2014) materials in the 6th the National Health and Nutrition Survey were applied to this study. The factors affecting general health related quality of life measured by EuroQol-5 dimension (EQ-5D) have been confirmed by gender, age, education level, income level, private health insurance, perceived health status, toothache experience during the last 1 year, remaining tooth number. As oral health plays an important role in determining the overall health conditions, objective oral health state influences the whole body health. Hence, it can be regarded that oral health is ultimately related to the general health-related quality of life.

Tobacco abuse is a major preventable cause of premature death and disease, including various cancers. The Global Adult Tobacco Survey India (GATS) 2009-10 revealed that more than one-third of adults use tobacco in one form or the other. Nearly two in five smokers and smokeless tobacco users made attempts to quit the habit in the past 12 months. Tobacco dependence is a chronic condition characterized by susceptibility of relapse over years. It can be well handled by sustained professional support from health care providers mainly through behavioral counseling and pharmacotherapy. Dental professionals can play a pivotal role in diagnosing and effectively managing tobacco dependence. Dental Institutions have rapidly grown in last two decades across the country and so has the curriculum been adapted to improve student competencies to accommodate changing disease patterns and technological advances, but not in regard to tobacco cessation. Untapped dental manpower like undergraduates, dental hygienists and other paramedical staff need effective training to be more penetrative. The present review paper explores the potential role of dental training institutions and recommends various approaches to counter public health jeopardy of tobacco related diseases.

Objectives: The objective of the study was to investigate oral health index between adequate and inadequate dental care following preventive scaling in regular dental check-up and management. Methods: The subjects in Busan were assigned to two groups including inadequate dental care (140 patients) and adequate dental care (88 patients) after preventive scaling from January 2014 to June 2015. The study instruments included oral health knowledge, awareness, practice, and community periodontal index of treatment needs (CPITN). Results: CPITN was significantly different between the two groups (p<0.05). Positive correlations were found in oral heath knowledge and awareness (r=0.462, p<0.05) before application of preventive scaling. There was a close correlation in oral health awareness and practice (r=0.205, p<0.05) before application of preventive scaling. After application of preventive scaling, oral health knowledge and awareness showed positive correlation (r=0.643, p<0.05). After application of preventive scaling, there was also a close correlation between oral health knowledge and practice (r=0.453, p<0.05). Oral health awareness and practice (r=0.512, p<0.05) showed positive correlation after the application of preventive scaling. However, oral health practice and CPITN (r=-0.189, p<0.05) showed a negative correlation. Conclusions: Practice made periodontal condition improve. To promote oral health practice in the group without adequate dental care, it is necessary to pay attention to adequate dental care and preventive scaling through education by dental hygienists.

Purpose: This study aimed to investigate the effects of the sintering conditions of zirconia core on the adaptability. Methods: Ten specimens of each of commercial brand of zirconia(Razor 1100, U&C international, Seoul, Korea) were made and sintered under three different conditions. Specimens were divided into three subgroup(n=10) and sintered with various total time(1hr, 3hr, 9hr) at the maximum temperature(1500℃). The digitized data was superimposed with 3D inspection software to quantitatively obtain the adaptation of a zirconia core, and visual differences were confirmed with a color map. The root mean square(RMS) values of group were statistically analyzed with one-way ANOVA(α=0.05). Results: The overall adaptation of the zirconia cores were as follows; ss-1hr: 36.18±5.2㎛, ss-3hr: 39.55±3.9㎛, cs-9hr: 46.62±4.3㎛. They were statistically significant differences between groups for adaptation(p<0.05). Conclusion: Based on the results of this study, it could be considered that sintering condition of 1500℃ and 1~3 hour is recommended for the better marginal and internal fit. Speed sintering can be widely utilized to fabricate zirconia prothesis as the properties of those almost are to dentistry uses.
