BACKGROUND: To prepare for possible emergency situations during dental treatment, it is helpful to know how often and what kinds of emergencies may arise. This study set out to evaluate the incidences, causes, treatments, and outcomes of emergency situations in the outpatient clinic of a dental teaching hospital in Korea. METHODS: We retrospectively reviewed the records of patients who had experienced an emergency situation and emergency response team activated in a selected outpatient clinic between November 2004 and November 2013. Specific information about the emergency cases was collected, including the patient characteristics and the frequency, types, treatments, and outcomes of the emergency situations. RESULTS: We identified 35 instances of emergency situations in 2,890,424 patients (incidence = 0.012 per 10,000 outpatients). The number of cases was as follows: 10 (28.6%) in the Department of Periodontics, 10 (28.6%) in the Department of Oral and Maxillofacial Surgery, 6 (17.1%) in the Department of Oral and Maxillofacial Radiology, 4 (11.4%) in the Department of Prosthodontics, 2 (5.7%) in the Department of Conservative Dentistry, 2 (5.7%) in the Department of Pediatric Dentistry, and 1 (2.9%) in the Department of Orthodontics. Three (8.6%) of the emergency situations arose before treatment, 22 (62.9%) during treatment, 7 (20.0%) after treatment, and 2 (5.7%) in a patient's guardian. CONCLUSIONS: In accordance with the growing elderly population and more aggressive dental procedures, the number of emergency situations may increase in the future. We recommend that clinicians keep in mind airway management and the active control of emergency situations.

Panoramic radiographs are a relatively simple technique that is commonly used in all dental specialties. In panoramic radiographs, in addition to the formation of real images of metal objects, ghost images may also form, and these ghost images can hinder an accurate diagnosis and interfere with the accuracy of radiology reports. Dentists must understand the formation of these images in order to avoid making incorrect radiographic diagnoses. Therefore, the present study sought to present a study of the formation of panoramic radiograph ghost images caused by metal objects in the head and neck region of a dry skull, as well as to report a clinical case n order to warn dentists about ghost images and to raise awareness thereof. An understanding of the principles of the formation of ghost images in panoramic radiographs helps prevent incorrect diagnoses.

Chinese Journal of Stomatology 2022;57(10):997-1002
In recent years, with the rapid development of digital technology, the application of oral virtual patients in prosthodontics, orthodontics, oral and maxillofacial surgery, and other disciplines has gradually increased. Although the focus on oral virtual patients varies in different disciplines, the application of oral virtual patients in assisting the prediction of treatment effects and the formulation of treatment plans will have good prospects. The construction accuracy and presentation effects of oral virtual patients can be influenced by the source of three-dimensional (3D) image, and methods of registration. Based on the studies and clinical experiences of our team, researches of other teams, the source of 3D images, the construction methods, and the clinical applications of virtual patients in prosthodontics will be presented, so as to provide a reference for normalized application and development of oral virtual patients and to offer a future development direction of oral virtual patients.

PURPOSE: The aim of this study was to assess the esthetic outcome of maxillary anterior single implants by comparing the esthetic perception of dental professionals and patients. MATERIALS AND METHODS: Twenty-three patients with single implants in the esthetic zone were enrolled in this study. Dentists of four different dental specialties (Three orthodontists, three oral surgeons, three prosthodontists, and three periodontists) evaluated the pink esthetic score (PES)/white esthetic score (WES) for 23 implant-supported single restorations. The satisfactions of the patients on the esthetic outcome of the treatment have been evaluated according to the visual analog scale (VAS). RESULTS: The mean total PES/WES was 12.26 ± 4.76. The mean PES was 6.45 ± 2.78 and mean WES was 5.80 ± 2.82. There was a statistically significant difference among the different specialties for WES (P<.01) and Total PES/WES (P<.01). Prosthodontists were found to have assigned poorer ratings among the other specialties, while oral surgeons gave the higher ratings than periodontists, orthodontists, and prosthodontists. CONCLUSION: Prosthodontists seemed to be stricter when assessing aesthetic outcome among other specialties. Moreover, a clear correlation existed between dentists' and patients' esthetic perception, thereby providing rationales for involving patients in the treatment plan to achieve higher levels of patient satisfaction.

PURPOSE: This study was to evaluate the beam quality of intraoral X-ray equipments used at Yonsei University Dental Hospital(YUDH) using the half value layer(HVL) and the characteristic curve of intraoral standard X-ray film. MATERIALS AND METHODS: The study was done using the intraoral X-ray equipments used at each clinical department at YUDH. Aluminum filter was used to determine the HVL. Intraoral standard film was used to get the characteristic curve of each intraoral X-ray equipment. RESULTS: Most of the HVLs of intraoral X-ray equipments were higher than the least recommended thickness, but the REX 601 model used at the operative dentistry department and the X-707 model used at the pediatric dentistry department had HVLs lower than the recommended thickness. The slopes of the characteristic curves of films taken using the PANPAS 601 model and REX 601 model at operative dentistry department, the X-70S model of prosthodontic dentistry department, and the REX 601 model at the student clinic were relatively low. CONCLUSION: HVL and the characteristic curve of X-ray film can be used to evaluate the beam quality of intraoral X-ray equipment. In order to get the best X-ray films with the least radiation exposure to patients and best diagnostic information in clinical dentistry, X-ray equipment should be managed in the planned and organized fashion.

AIMTo examine what impact the loss of funding had on the utilization of the oral pathology service.
METHODOLOGYBiopsy records were retrieved and examined in the two year period before and after the elimination of the subsidies in 2003.
RESULTSAfter the loss of funding, there was a 31% decrease in the number of specimens submitted from practitioners in private practice, with the greatest drop noted in submissions from endodontists.
CONCLUSIONDespite the immediate decrease in the number of biopsies submitted after the introduction of fee-for-service, the number of specimens being submitted appears to be on the rise again, as practitioners appear to recognize the value of a specialized oral pathology diagnostic service.
