Purposes: This study aims to compare financial performances and factors affecting profitability between dental university hospitals and medical university hospitals and suggest ways of improving dental university hospitals’ business performance. Methodology: Data from 2016 to 2019 was collected from financial statements, public open data in 8 dental university hospitals and 8 medical university hospitals. For the study, independent sample t-test for comparing mean difference and multiple regression for identifying factors affecting profitability were applied. Findings: There were significant mean differences between dental and medical university hospitals in current ratio, liabil ity, long-term borrowings to total assets, employment cost rate, material cost rate, management expense rate, non-operating revenue rate, patient revenue per a specialist and an employee, outpatient revenue rate, patient revenue per a patient, patient revenue per a inpatient. Profitability of both hospitals were affected by employment cost rate, material cost rate, manage ment expense rate. Practical Implication: To improve dental university hospitals’ business performance with research results, firstly, it needs to actively invest medical business with proper amount of current assets and borrowings. Secondly, it is necessary to extend non-operating business such as rental revenue, research grants, contribution income. Thirdly, it is required to analysis and manage their cost to build sustainable business environment.
Purpose: Phosphatase and tension homolog (PTEN) has been known to play a role of maintenance of homeostasis over the body. It is little known about the roles of PTEN in periodontal complex. The purpose of this study was to explore the role of PTEN in periodontal complexes after removing PTEN from osteoblasts and odontoblasts. Materials and Methods: The resulting OCN‐Cretg/+;Ptenfl/fl mice were created after by conditionally eliminating the PTEN gene using an Osteocalcin (OCN) Cre driver and the resulting OCN‐Cretg/+;Ptenfl/fl mice (experimental group) were compared with the wild type mice (control group) using micro-CT, histology and immunohistochemical analyses. The amount of dentin and alveolar bone was analyzed, and osteopontin and bone sialoprotein in the periodontal ligament space (PDL) were evaluated and collagen in the PDL was analyzed quantitatively and qualitatively. Results: Micro CT showed that dentin and bone were significantly accumulated in an experimental group. Dentin sialo protein was significantly increase in dentin of an experimental group. Internal balance in the PDL was altered with increased expression of PCNA in an experimental group. Conclusions: Loss of PTEN causes an increase of dentin and bone in the periodontal complexes with an alteration of internal balance in the PDL. These findings underscore the effect of PTEN on homeostatic control of periodontal complexes.
Cardiopulmonary resuscitation guidelines are revised based on scientific evidence for emergency treatment of cardiac arrest patients. Refreshing the scientific knowledge of cardiopulmonary resuscitation leads to changes in the social-medical environment for cardiac arrest treatment. It aims to ultimately increase the survival rate of cardiac arrest patients by re-learning with changed guidelines every five years. Most emergency situations that occur to outpatients visits dental clinic are relatively low in risk. However, as the number of elderly patients is increasing and sedative anesthesia is becoming more common, life-threatening environments such as fainting, allergic shock, respiratory arrest, and cardiac arrest are increasing. As a medical practitioner, dentists should be able to provide appropriate emergency treatment. In this article, we would like to discuss the major changes in the revised Korean Association of Cardiopulmonary Resuscitation(KACPR) and American Heart Association (AHA) guidelines in 2020.
The American Dental Association states that the administration of local anesthesia, sedation and general anesthesia is an integral part of dental practice. It is significant that the American Dental Association defines sedation as well as local anesthesia as an integral part of dental practice. A new sedation guideline was published in Korea in 2022. This guideline has been published to help both anesthesiologists and non-anesthesiologists provide safe and effective moderate sedation to patients consistently, without limitation, at any medical institu tion. This guideline was developed with a focus on moderate sedation before, during, and after examinations or procedures for diagnostic and therapeutic purposes. Considering that there is a possibility of transition from moderate to deep sedation depending on the drug administered and the characteristics of each patient, the guide line also includes items for monitoring and coping with complications that may occur due to cardiovascular and respiratory depression. It consists of recommendations for a total of 15 PICO (participants, intervention, com parator, outcome) questions. Individual items covered include education on sedation providers, requirements for supplying drugs and equipment for sedation, selection of appropriate patients, referral to an anesthesiologist when performing sedation for high-risk patients, fasting before sedation, and typical use in adults and children. Comparison of drugs, monitoring of respiratory system, cardiovascular system, depth of sedation during seda tion, measures to cope with respiratory complications during sedation in children, and discharge criteria after sedation are included.
Pain control according to sensory nerve innervation in the oral and maxillofacial area is an important part of clinical dentistry for treating diseases of teeth, periodontal tissue, oral mucosa, temporomandibular joint, and maxillofacial area. Local anesthesia has been used the basic pain control procedure in dental treatment. Dental local anesthesia is a basic procedure in the curriculum of dental schools, and is the most frequently used dental procedure by many dentists in clinical practice. As one of these procedures, we would like to review the consid erations of whether clinical guidelines for these procedures are necessary
