Its analysis of their perspectives are as follows. 1. The common characteristics of the subjects are that 40.1% of them are under 25, and their working period was under three years with the 38.9%, and as for their marital status, 70.2% were single, the final education of 80.2% were associated degrees. Their working areas are centered in Gyeongsangnam-do province with 91.2%, the workplace type is for the dental clinic with 80.2%. 2. The comparison of the view point of the medical(technician) law according to the characteristics of the research subjects differed only whether or not the completion of the education, and as a result of the comparison according to the characteristics of those subjects understanding the details of the medical(technician) law, there was a significant difference saying "the current law has clear job description" depending on the working area or "the job duty is definite" depending on the job experience and job details. As for those saying "the job duty is definite", there was also significant difference depending upon marital status, final education and work details. There was no significant difference in all characteristics from findings of the necessity of legal system according to the subjects not understanding the medical(technician) law. 3. As a result of comparing the necessity of the medical(technician) law according to the characteristics of the research subjects, it was found that all the subjects accepted the necessity of the medical law revision including the dental hygienist in the medical person. The "necessity of the professional dental hygienist system" showed a significant difference depending upon the final education and medical institution type. Among the triggering factors in its amendment, there showed significant difference in the "cooperation of other organizations" and "solution of medical law problems" only in the final education. 4. As a result of comparison of the needs of the medical(technician) law revision according to the characteristics of the research subjects, it was found that the significant traits related to the age and job details showed "Legal responsibility would be increased" when the medical law is revised, in case that "it will help broaden the job extension", there showed a significant difference in career, final education, and working institution, and job details. "Legal protection is possible" showed significant difference except the age group and working area, and "it help the system settlement" showed in the final education. There was a significant difference in career, final education, and job details that "I can regulate the education and field practice", and the same in "my status will be improved" depending upon the final education, work area, and job details. Accordingly, in this research, for the establishment of more professional and comprehensive dental health service as suggested from the demand and necessity toward the medical(technician) Law by the dental hygienists.

With the change of medical environment, people are taking interest not just in treatment but in the prevention of oral diseases. As people's interest in oral diseases increases, the number of dental institutions is increasing continuously and this is heightening the necessity and importance of professional dental hygienists equipped with expert knowledge of oral health. Thus the present study purposed to survey and analyze the current state and weight of works carried out by dental hygienists, and to propose dental hygienists' works desirable in the medical environment changing its focus from treatment to prevention. The results of this study are as follows; 1. In the results of dividing dental hygienists' works into oral examination and preliminary examination, preventive works, assistance to dental treatment, oral health education, hospital administration and management, and surveying the performance rate of these works, the work of the highest performance rate in preliminary examination was collection of patients' systemic history (87.6%). It was also scaling (96.9%) in preventive dental treatment, preparation for treatment (96.5%) in assistance to dental treatment, education on the toothbrushing method (92.3%) in oral health education, and tool disinfection and management (72.2%) in hospital administration and management. 2. When the performance rate was surveyed according to age, institution, and work experience, the performance rate by work area was highest in dental hygienists aged between 27~28, those working at a dental clinic, and those with 4~6 years' work experience. 3. The weight of dental hygienists' works was high in order of assistance to dental treatment (59.1%), observation of oral health condition and preliminary examination (12.4%), oral health education (12.4%), hospital administration and management (10.4%), and preventive dental treatment (5.8%), but in the results of surveying perception on the importance of works, the importance was high in order of oral health education (34.7%), preventive dental treatment (29.0%), observation of oral health condition and preliminary examination (19.3%), assistance to dental treatment (11.2%), and hospital administration and management (5.8%), showing that the weight of works carried out current was different from perception on the weight of works regarded as important. 4. To the question on parts to be developed in response to the change of medical environment, the most frequent answers were the establishment of their roles as preventive dental practitioners (75.7%), and the establishment of their roles as oral health educators (74.9%). This was consistent with the works that dental hygienists gave the highest weight to, and suggested that dental hygienists regarded preventive dental treatment as most important. Development of abilities to give counsel to patients was 55.2%, acquisition of theoretical knowledge of dental treatment 42.1%, improvement in quality as a hospital manager 28.2%, and acquisition of skills to assist dental treatment 23.2%. These show that, even with regard to the development of future oriented dental hygienists' capacities, assistance to dental treatment was perceived less important as it was with regard to the importance of work.

This study researched into literature materials in order to utilize basic data on job importance in dental coordinator, and analyzed questionnaire on job importance in dental coordinator for about 2 months from August and September in 2008 targeting dental hygienists and other manpower for dental hospitals & clinics where are located in D region and neighboring region. The following are the results: 1. Dental hospital & clinics where dental coordinators work were surveyed to be totally 66.9%. Dental coordinators were indicated to be 71.1% as for dental hospital$^{\circ}{\S}$clinic(women), and to be 28.4% as for a case with none. There was significant difference according to final academic degree and working place(P<.001). 2. License holders(women) for dental hygienist as dental coordinator accounted for 39.8%. The opposite case accounted for 60.2%. A case of doing duty of dental coordinator given not dental hygienist was indicated to be high. There was significant difference according to working place(p<.01). 3. The task importance on job that a dental coordinator directly performs was indicated to be averagely 3.24, thereby having been recognized to be important. 4. As for the recognition on job importance according to working-year number, it was indicated to have higher recognition on task importance in the more working-year number regarding customer management(p<.01), organization management(p<.05), and self-management(p<.01). 5. Given seeing difference in recognition on task importance according to medical institution, it was indicated to be 3.34 for dental clinic and 3.25 for dental hospital. Thus, the task importance was indicated to be slightly high in a person who works for dental clinic. There was no significant difference. In light of the above results, in order to educate dental coordinator who can successfully perform a role at dental hospital & clinic, a dental hygienist is required who is equipped with dental-clinic career rather than a person without a major. A professionally educational program for dental coordinator needs to be developed. Even in a dental coordinator's task, there is necessity for the curricular development and the specialized education.

Adhesion of composite resin to tooth structure has been of tremendous signgicance in clinical dentistry. Due to the lack of adhesion between composite restorative resins and enamel and dentin, microleakage occurs at the tooth/restoration interface. This may lead to discoloration, secondary caries, marginal breakdown, postoperative sensitivity, and even pulpal pathology. According to extensive use of composite resin, every effort on improving bonding strength and reducing microleakage between a tooth and composite resin has been continued. This study was conducted to determine the difference in microleakage in enamel and dentin treated with air-abrasion, acid etching and combination when restored with composite resin. Class V cavities were prepared on 30 premolars. The specimens were divided into following groups. group 1:air-abrasion+Scotchbond Multi-purpose group 4 :air-abrasion+All-Bond 2 group 2:acid etching+Scotchbond Multi-purpose group 5 :acid etching+All-Bond 2 group 3:combination+Scotchbond Multi-purpose group 6 :combination+All-Bond 2 #combination:air-abrasion + acid etching The specimens were filled with Z-100 after application of Scotchbond Multi-purpose and All-Bond 2. Thermocycling was conducted by alternately dipping the specimens in $5^{\circ}C$ and $55^{\circ}C$ water for 30 seconds 500 times. 1% methylene blue was applied and the specimens were left for 24 hours at $37^{\circ}C$. After washing out the dye, the tooth was sectioned buccolingually along the axis. The sectioned surface was observed with stereoscope for dye penetration. The author has measured the microleakage in teeth prepared with air-abrasion, acid ethching and combination to study the difference in microleakage following different methods of tooth surface treatment and has come to following results. 1. In comparing microleakage between groups, group 1 and 4 showed statistically significant difference from group 2, 3, 5 and 6(p<0.05). There was no significant difference among group 2, 3, 5, 6(p>0.05) nor between group 1 and 4(p>0.05). 2. In comparing microleakage among tooth surface treatment methods, Air-abrasion group showed significantly more microleakage than acid etching group and combination(airabrasion + acid etching) group(p<0.05). Combination(acid etching+air-abrasion)group tended to show lesser microleakage than acid etching group, but this was not statistically significant(p>0.05). 3. In comparing microleakage between bonding agents, there was no statistically significant difference between Scotch bond Multi-purpose and All-Bond 2(p>0.05).

본 연구에서는 CT 장비의 국내에서의 보급률과 이용률이 증가되고 있는 흐름과 증가의 변화와 장치의 변화가 검사부위에 나타나는 빈도 등을 정량적으로 파악하기 위하여 현재 우리나라의 의료기관 종별 및 시기별의 의료영상 진단 장비인 CT장치의 보유현황, 검사료 등을 조사하였다. 최근 10년간의 우리나라 의료기관 종별(상급종합병원, 종합병원, 병원, 의원, 치과병원, 보건의료원, 한방병원) 및 연도별(2003~2012)에 따른 CT장치 보유현황, 연도별 CT검사료를 의료기관 종별의 분포를 조사하였다. 우리나라 CT장치는 상급종합병원과 종합병원급 의료기관에서 보유한 총 비율은 2003년에 25.6%, 2011년에 32.5%정도인 반면, 병원과 의원급 의료기관에서 보유한 비율은 2003년에 73.5%와 2009년에 67.5%로 약 70%를 차지하고 있는 것으로 나타났다. 2011년도를 기준으로 하였을 때 상급종합병원과 종합병원에서 총 검사료의 82.4% 정도인 반면, 병원과 의원에서는 총 검사료의 17.6%로 나타났다. CT장비는 병원급은 증가하고 있는 추세이나 의원급은 감소하고 있는 것으로 나타났다. CT검사료 대부분은 80% 이상이 상급종합병원과 종합병원에서 청구하는 것으로 나타났다. 의료기관 종별 CT장비 보유현황과 검사료간의 상관관계가 유의미함을 알 수 있다. 그 중에서도 상급종합병원의 CT보유대수와 검사료간의 상관관계가 높았으며(p<.001), CT보유대수가 많아질수록 검사료 청구액도 높아진 것으로 나타났다.

우리나라 구금시설은 구강건강 관리 인력과 시설이 부족하고, 수용자의 구강질료 시 절차가 복잡하여 필요할 때 적절한 진료를 제대로 받지 못하는 편이다. 이러한 문제로 인해 수용자의 건강권이 충분히 보호받지 못하고 있다. 정보노출을 기피하는 구금시설로부터 수용자와 관련된 자료를 수집하는 것도 어렵다. 따라서 수용자의 전신건강에 대한 연구는 매우 드물며, 구강건강에 관한 논문은 거의 찾아볼 수 없다. 이에 이 연구는 구금시설 내 치과진료체계 및 구강보건의료인력을 파악하기 위하여 관련 문헌조사, 전화 및 설문조사를 시행하여 다음과 같은 결과를 제시하는 바이다. 1) 문헌조사 1. 2002년 당시 수용자의 69.0%가 입소 시에 건강검진을 받았지만, 구강검진은 18.5%만이 받았다. 2. 2004년 당시 전체 46개 구금시설 중 42개에 치과의무실이 설치되어 있었다. 2) 전화 및 설문조사 1. 2009년 현재 총 26명의 전임 치과 공중보건의사가 배치되어 있었으며, 구강보건의료인력을 모두 갖춘 곳은 한 곳도 없었다. 2. 하루 평균 약 10명의 수용자가 구강진료를 받고 있었고, 외부의 치과의사는 한 달에 평균 4회 방문하였다. 그리고 '구강진료의료인력 부족'으로 인해 치과진료가 원활하게 진행되지 않는다고 여기고 있었다. 3. 수용자의 외부진료가 대부분 수월하지 않다고 답하였고, 그 주된 이유로는 '환자의 출입이 통제되어서'라고 응답하였다. 4. 구강보건교육은 일부 치과의사가 진료 시에 수행하고 있었으나, 전체 수용자를 대상으로 하는 정기적인 구강보건교육은 전혀 이루어지지 않고 있었다. 무엇보다 구금시설 수용자의 의료처우 개선과 구강건강증진을 위해서는 수용자의 구강건강 요구도 등을 제대로 파악해야 한다. 이 연구는 앞으로 구금시설의 치과진료체계에 대한 문제점을 개선하고, 수용자의 구강건강 문제를 해결하는데 필요한 참고자료로 활용할 수 있을 것이다.
