The purpose of this study is to propose a management method to maintain the pleasant indoor air quality of the dental clinic by measuring and analyzing the indoor air quality of the dental clinic. The measurement was conducted in two rooms, a lobby where many residents stay in the reception room for waiting for medical treatment, and a VIP room where treatment activities are mainly performed. Measurement items are Temperature, Humidity, $CO_2$, CO, $NO_2$, $CH_2O$, VOC, $PM_{10}$ and measurement were taken on April 27, 2018. As a result of analyzing the temperature and humidity of the dental clinic, it was analyzed that the average indoor temperature was maintained at $25^{\circ}C$ and the humidity was kept at around 50%, maintaining proper indoor temperature and humidity environment. $CO_2$ was 855ppm in the VIP Room, which satisfied the maintenance standard. In the case of the lobby, it was analyzed to be 1,160ppm, which exceeded the maintenance standard and it is judged that the carbon dioxide generated by the respiration of the people staying in the lobby is the main reason. The mean concentration of formaldehyde in the VIP room was analyzed as $436{\mu}g/m^3$, exceeding the maintenance standard, and $2,100{\mu}g/m^3$ for the VOC exceeded the recommended standard. It was analyzed that the concentration was relatively higher due to the use of disinfectant and other drugs. The mean concentration of PM-10 in the lobby was analyzed as $65{\mu}g/m^3$ and it was analyzed that it satisfied the maintenance standard. To maintain a pleasant indoor air quality in a dental clinic it is necessary to minimize the effects of formaldehyde, VOC, $CO_2$ in the VIP rooms and lobby. For this purpose, the entire ventilation system and air purification system of the dental clinic should be installed. In case of the VIP room, local exhaust ventilation should be installed and workers should wear personal protective equipment.

본 연구는 치과병원에서 진료 시 발생하는 소음특성을 NR-곡선, PSIL에 적용하여 소음수준 및 적절한 대화거리를 산정한 결과를 제시하고자 실시하였다. 치과병원에서 치료 시 소음특성을 분석한 결과 소음에 의한 건강 보존한계 값인 60dB(A)을 초과하고 고주파 성분의 소음도가 높은 것으로 분석되었다. NR곡선에 적용하여 평가한 결과 일부 치료 시 작업장 소음기준을 초과하고 근무자와 환자 사이에 이루어지는 대화에 대한 회화방해도 수준을 분석한 결과 보통크기의 소리일 경우 0.13m~0.42m, 큰 소리일 경우 0.26m~0.85m 정도 인 것으로 분석되어 환자와 근무자 간의 정확한 의사전달을 위하여 가급적 1m 이내의 거리에서 대화가 이루어지는 것이 바람직 할 것으로 판단된다. 병원의 의료서비스 질의 향상을 도모하고 치과공포를 감소시키기 위하여 근무자에게 방음보호구를 지급하고 소음 발생원(진료 시 사용되는 치료기기) 및 수음원(환자 및 근무자)에 대한 방음대책도 필요 할 것으로 판단된다.

A comparative study was conducted to evaluate the relationship of investing medium to the amount of vertical occlusal changes and to the differences of surface smoothness during denture construction. Three groups of 20 dentures, 30 sets of upper and lower were fabricated of conventional heatcuring acrylic denture base resin, using silicone-gypsum molding techniques, with or without covering the occlusal surfaces of the teeth by artificial stone and all-gypsum molding techniques. The distance between the two reference points indented by 1/2 round bur on the upper and lower frontal surfaces of each articulator were measured and recorded before processing and again after processing and remounting of each denture on the articulator. The differences between the two recordings indicated the amount of vertical opening during denture processing. The difference of surface smoothness were investigated and determined by 3 observers continual comparing of the two randomly selected dentures with each other, which were seperately selected as pairs from the different two groups of 20. The results obtained were as follows: 1. During resin processing no statistically significant differences of the amount of vertical occlusal changes were detected between any of the two groups of two silicone-gypsum and one allgypsum molding techniques, although the amount of vertical opening was somewhat increased when silicone-gypsum molding technique was used. 2. Surface smoothness of the processed denture was makedly by increased when silicone-gypsum molding technique was used.

Purpose : Hypochlorous acid (HOCl), a major inorganic bactericidal compound of innate immunity, is effective against a broad range of microorganisms. In particular, HOCl is well-known as a non-antibiotic antimicrobial substance. However, effects of HOCl as an antimicrobial agent are still needed to study these functions against various specific type of microorganisms. In this study, we investigated the antimicrobial effect of hypochlorous acid (HOCl) in S. mutans and A. actinomycetemcomitans to cause dental caries and periodontal disease. Experiments were conducted to observe whether HOCl become effective replacement of disinfectant. Methods : To observe antimicrobial effect of HOCl, stabilized HOCl is prepared in the form of a physiologically balanced solution in pre-conditioned and post-conditioned HOCl solution. As a control, commercially available disinfectant MAXCLEAN was used as positive control. Moreover, S. mutans and A. actinomycetemcomitans distribution in gagrin, filtered tap water, and culture media. Cell viability were measured by viable cell count methods and disk diffusion test. Results : Our results showed that treatment of HOCl have no effect against antimicrobial effect compare to control group especially gagrin in disk diffusion test. HOCl tended to reduced viability against S. mutans in group of post-conditioned than pre-conditioned of HOCl solution however, there was no significant difference as well as no effect in A. actinomycetemcomitans. Conclusion : HOCl showed tendency to reduce viability against S. mutans in group of post-conditioned of HOCl solution and no effect of antimicrobial effect. Although HOCl is well known as effective against a broad range of microorganisms, HOCl seems to have diversity following type of species to be used as antimicrobial drug following our results. Therefore, it is necessary to be rigidly controlled and regulated in using HOCl solution clinically.

In dental prosthetics, the application of metal-ceramic restorations has steadily increased since their introduction. This is due to excellent esthetics in combination with high mechanical stability. In order to optimum bond strength between metal and ceramics, controlled oxidation of metal substructure is essential factor. Beryllium containing and beryllium free Ni-Cr alloys for metal-ceramic restorations were evaluated for the metal-ceramic bond strength by changing heat treatment for oxide formation. A mechanical three-point bending test was employed to evaluate the interfacial bond strength of metal-ceramic. In each metal, plate type specimens were used for mechanical three-point bending test. With Ni-Cr alloys for metal ceramics, mechanical three-point bending test showed that double degassing was more available preheat treatment method than another. It was found that beryllium containing Ni-Cr alloys are more effective than beryllium-free for metal-ceramic bond strength.

3-dimensional information for anatomic stucture plays a role as integral part in clinical aspect of dental practice. CBCT(cone beam computed tomography) has been accepted as useful diagnostic tool offering Volume data and images for evaluating teeth and jaws in lower radiation dose than conventional CT. CBCT equipment is essential for the quality assurance of it to ensure continued satisfactory performance and result of adequate images. Dental practitioner and oral and maxillofacial radiologist should have a responsibility and critical thinking to deliver this technology to patients in a responsible way, so that diaganostic value is maximised and radiation doses kept as low as resonably achievable. CBCT imaging modality should be used only after a review of the patient's health and imaging history and the completion of a thorough clinical examination. Clinical guidelines are systematically developed statements to assist practitioner and patient decisions about appropriate health care for specific clinical circumstances Dental practitioners should prescribe CBCT imaging only when they expect that the diagnostic yield will benefit patient care, enhance patient safety or improve clinical outcomes significantly. Knowledge of patient dose is essential for clinicians who are making the decision regarding the justification of the exposure. There are some limitation in the measurement of patient dose in CBCT for the approval and adaptation of conventinal methodolgy in CT. It is also important to ensure that doses are optimised and in line with any national and international guidelines. The higher radiation doses of CBCT compared with conventional radiography, mean that high standards must be maintained. The Quality Assurance(QA) programme should entail surveys and checks that are performed according to a regular timetable. QA programme should be maintained by staff to ensure adherence to the programme and to raise its importance among staff.
