Prosthetics procedures in dental clinics 1) Tooth preparation 2) Temporary restoration 3) Post and core 4) Impression 5) Cementation of final prosthesis The final step in the prosthodontic procedure is the fitting of the final prosthesis to the patient's abutment with an exact fit and occlusal relationship. By the way, this final prosthesis is not made in the clinic but is made in the dental lab and comes to the clinic with some time difference. In the clinic, the only medium to deliver the patient's oral information to the dental laboratory is the impression. However, many errors occur in this process. Dentists and dental technicians should try to identify the cause and make an accurate prosthesis to reduce this error.

연구배경: 장애인의 치과치료는 일반인의 치과치료와는 달리 많은 문제점들을 가지고 있다. 이러한 장애인 환자의 치과치료를 위하여 서울대학교 치과병원에서는 치과마취과를 중심으로 임상 각과가 협진하여 외래마취 기반 하에 1999년부터 장애인 진료실을 운영하고 있다. 이번 연구에서는 서울대학교 치과병원 장애인 진료실의 치료방법을 소개하고 그 동안 치료받은 장애인 환자들의 자료를 바탕으로 마취과적인 특징을 분석하였다. 방법: 2001년 1월부터 2002년 5월까지 치료받은 총 54명의 장애인 환자들의 치료기록지와 마취, 그리고 회복실 기록지를 검토하였다. 환자의 성별, 나이, 전신질환, 수술 전 시행된 검사, 치료에 참여한 협진과, 마취 유도제와 유지제, 총 마취시간과 회복실 체류시간, 그리고 회복실에서 관찰된 합병증을 조사하였다. 결과: 총 54명의 환자들을 대상으로 58건 치과치료가 시행되었다. 한 건의 의식진정 법을 제외하고는 모두 전신마취 하에서 치과치료가 시행되었다. 마취유도제는 thiopental sodium, 근이완제는 vecuronium과 succinylcholine가 가장 많이 사용되었으며 마취 유지를 위해서는 enflurane과 isoflurane의 흡입마취제를 이용하거나 TCI를 이용한 propofol 지속정주를 이용하였다. 총 마취지속시간은 $160.2{\pm}55.5$분이었으며 회복실에서의 체류시간은 $132.8{\pm}50.1$분, 그리고 완전한 회복을 확인하기 위해 병동에 단기 입원시킨 소아환자에서는 $58.7{\pm}16.8$분이었다. 회복실에서 심각한 합병증은 발생하지 않았다. 지속적인 감시를 위하여 4명의 환자가 입원을 권유받았으나 특별한 합병증 없이 다음 날 퇴원하였다. 결론: 서울대학교 치과병원 장애인 진료실은 외래마취에 대한 기존의 연구들보다 긴 마취시간과 회복실 체류시간을 보였다. 그러나 별다른 합병증 없이 일회 방문으로 장애인 환자들에게 필요한 치과치료를 모두 제공할 수 있었다.

The aim of this study was to investigate the change of microbial contamination levels in the different areas and at the different time points after application of a quaternary ammonium compound (QAC) that has mechanical antimicrobial effect. The microbial contamination levels were measured in three different areas; unit chair handle, spit sink area and hand piece holder at different time points using adenosine triphosphate (ATP) monitoring system and ATP surface test kit. Hand piece holder showed the highest level of microbial contamination. In most of the clinics, QAC significantly reduced the levels of microbial contamination, and maintained antimicrobial activity for 4 to 6 months. QAC may be used effectively in dental clinics due to the duration of antimicrobial effect and the minimal exposure of chemicals and further studies are needed with large sample size.

The purpose of this study was to investigate the distribution of microorganisms and the degree of contamination in the air of the dental clinics and to offer basic data as to the contamination of medical equipment and the prevention of the clinics. With this in mind, the researcher gathered air samples from the waiting rooms and medical offices of nine dental clinics in the city of J, South Korea with the use of a method of natural inattention and an air sampler and cultivated the samples on the plain table and drew from it bacteria falling and separated and sorted out the colony with the help of ATB and detected the distribution of the germs. The results are following, The number of bacteria falling in the air of the dental clinics was less than 10(CFU/Plate) with the exception of one dental clinic. This implies that they fit in with standards for hygiene. The number of bacteria falling in the air of the medical offices was less than 10(CFU/Plate) with the exception of one dental clinic. This implies that they fit in with standards for hygiene. The survey on the detection of staph. aureus reveals that all the dental clinics with the exception of B dental clinic proving to be positive had non-pathogenic staphylococci detected. The survey on the detection of pathogenic gram negative bacilli indicates that all the dental clinics but one were none detected. The survey on the distribution of germs shows that germs in 7 out of 9 dental clinics were none detected, and that they in four out of 9 waiting rooms were none detected. All the germs detected in the others were mostly non-pathogenic. The study shows that all the subject dental clinics but one were hygienically controlled and that there was a difference in accordance with cleaning and sterilization. This means that dental clinics should be equipped with systematic programs for cleaning and sterilization designed to prevent infection.

This report demonstrates a method of generating a chair-side and computer-aided template for implant surgery based on the Top-Down and restoration-driven concept. Compared to the traditional CAD-CAM process which requires multiple steps to be taken between dental clinic and laboratory, this alternative procedure, VARO guide system (VARO Guide, CAD, Pre-Guide, VARO-mill, NeoBiotech, Seoul, South Korea) enables accurate and patient-friendly implant surgery as well as immediate provisional restoration in a single visit. First, bite-registration at centric jaw relation and CBCT were taken using the Pre-Guide. The CBCT data was then reorganized directly through the chair-side CAD, and we could determine the most appropriate 3-dimensional position of implant. The STL file was extracted and put into the chair-side CAM (VARO-mill) to fabricate a VARO. This surgical guide allowed the implants to be accurately positioned into the planned sites within an hour.

For the successful prosthetics treatment, the collaboration starting from the initial stage between dental clinic and laboratory is important. However, the collaboration can't persist all the processes, giving the ideal shape to prosthetics is one of the responsible part of dental laboratory. I'm going to explain how to access dental technician to case in restricted circumstance.

The characteristics of dental treatment makes the dental staff frequently contact with patient directly. Also the daily use of high-handpieces, sharp instruments, and needles often causes bleeding on oral cavity. Therefore, the risk of cross transmission grows up. The pathogen from dental practice could spread on not only the practice itself but also the dental laboratory with contaminated impressions and prosthesis. Dental clinic staffs (dentists, dental hygienists and dental technicians) should recognize all the patients have a possibility of cross contamination, and try to prevent the transmission of infection by proper infection control. In this study, we review the articles about disinfection methods and chemical infection agents used for dental impressions, and try to figure out the suitable and effective infection control system of dental impressions.

This research is aimed at cutting off hearing loss and other harmful factors due to noise and providing basic material for noise reduction plan. As the research method, this research assessed noise by measuring acoustic pressure level and frequency in various situation of non-treatment and treatment. As the measurement result, average noise degree of high speed handpiece of non-treatment, ultrasonic waves scaler, and low speed handpiece showed 58~66 dB(A). Average noise degree of scaling of treatment, tooth elimination, and denture adjust showed 73~81 dB(A). The result is inferior to recognized standards of noise induced hearing loss. But the result of assessing this with (noise rating) NR curve was NR-73~78, which exceeded general workplace noise standard. This level can cause hearing loss when exposed to a long time. Therefore, treatment office noise during dental treatment can cause psychological and physical damage in dental clinic employees, and it is urgently required to establish systematic and active noise reduction plan.
