Evaluation of the (clinical) relevance of gross anatomical teaching for dental students and practicing oral surgeons in Berlin.

Knowledge of human anatomy is an important scientific basis for every dentist, and the adequacy of its provision by anatomy faculties is therefore constantly being adapted. Students' motivation to comprehend knowledge is a fundamental prerequisite and has been shown to increase when the relevance of the subject is clear. This study examines dental students' perceptions of the relevance of the anatomy curriculum, with particular reference to clinical practice and the dissection course, in conjunction with the perceptions of surgically specialized dentists. The distinctions between the participating groups concerning their perceived relevance are being discussed particularly regarding their applicability to improve the anatomical education of dental students. The overall aim is to find and highlight aspects of the clinical use of anatomical knowledge towards students, which they are unable to apprehend yet. A questionnaire consisting of information on demographics and professional competence as well as a Likert-style section was administered to dental students at Charité Universitätsmedizin in 2019/2020 (n = 322, 84.96%) and a modified version with congruent questions was administered retrospectively to oral surgeons practicing in Berlin in 2020 (n = 81, 63.3%). A Wilcoxon rank-sum test was used to examine differences in responses between the cohorts. Demographic data and professional competence were correlated with the participants' ratings of the given statements using Spearman's rank correlation coefficient. Both groups of respondents expressed a high level of appreciation of the overall relevance of anatomical knowledge, valued the teaching of all human anatomy for dental education, and recognized the relevance of anatomical knowledge for clinical practice. The importance of the dissection course was also rated relatively high by both groups of respondents. The overall appreciation of anatomical knowledge was more prevalent among oral surgeons. There were few correlations between demographics in our findings, showing slightly higher motivation in female students and a growing appreciation of anatomical knowledge as students qualification progressed. The demographics and post-qualification experience of the participating oral surgeons did not influence their perceptions. The results of this survey suggest that there is potential to increase the motivation of dental students to learn anatomy by emphasizing clinical relevance, as perceived by experienced practitioners, during the anatomy curriculum.

Survey of United Kingdom oral and maxillofacial surgery (OMFS) specialists and trainees about the reasons that they retain or drop their registration with the General Dental Council (GDC) including a summary of changes in the numbers registered with the GDC 2014-2023.

When dual degree OMFS training was mandated in the UK in 1995, OMFS specialists were required to be registered with both the General Dental Council (GDC) and General Medical Council (GMC). In 2005 this legal requirement for dual registration with both regulators was removed. During 2021 the authors surveyed UK OMFS specialists and trainees asking them why they chose to remain on or leave the Dental Register to give context to the changing numbers of OMFS specialists and trainees holding Dental Registration between 2014 and 2023. In 2014 of 539 OMFS specialists and trainees only 62 (12%) were solely GMC registered, that is, they had let their Dental Registration lapse. In 2023, of 709 OMFS specialists and trainees, 320 (45%) were solely GMC registered. Those whose first qualification was medicine were less likely to be dually registered. Of those who replied to the survey and remained dually registered, most (40%) based this decision on 'worries about the consequences' of dropping their dental registration. Some other reasons were not based on fact at that time. Cost was the most common reason (49%) given for dropping their GDC registration by respondents who were only registered with the GMC. On the positive side, the January 2023 GDC position statement about OMFS who are not on the Dental Register removed the GDC's previous restriction on location of practice and teaching dental students. However the statement does not unambiguously allow OMFS surgeons to practice across the full OMFS curriculum. Will the 2023 GDC position statement alter the trend of OMFS specialists and trainees towards single medical registration?

Training simulation for oral and maxillofacial surgeons based on the techniques of arthroscopy in the temporomandibular joint.

Arthroscopy is a diagnostic-therapeutic technique used in the treatment of disorders of the temporomandibular joint (TMJ). The difficulties of arthroscopy lie in the manipulation of the tools, which is why training in the technique of triangulation in artificial models is essential. We developed a training system based on the techniques of arthroscopy in the TMJ, using simulators. The first simulator was a metal box containing three holes for insertion of the instruments, and the second was a human artificial model made of polymers. We found that they facilitated training in the techniques of arthroscopy, which subsequently reduced operating time and led to a better execution of skills in reality.

Oral Surgeons as Cosmetic Surgeons and Their Scope of Practice.

BACKGROUND: In recent years, the practice of cosmetic surgery has expanded to include oral and maxillofacial surgeons. The groundwork for this scope-of-practice expansion was laid in part by the American Dental Association's definition change of the practice of dentistry. This change modified the scope of dentistry from the earlier "teeth and surrounding and supporting structures" to the maxillofacial area and beyond. A number of states adopted this new definition into legislation, giving practitioners the premise on which to perform cosmetic and other medical procedures on the face and potentially other parts of the body. This expansion has created legal and regulatory issues over scope and truth in advertising. The authors hypothesize that this is confused by a lack of federal guidelines and state-by-state variations in scope-of-practice laws for oral and maxillofacial surgeons. METHODS: This article provides a brief overview of the key legal issues and their impact on legislation in some of the battleground states. The authors review the national distribution of scope of practice for oral and maxillofacial surgeons. RESULTS: The most successful path to expanded scope for dentistry has been through control of certification and credentialing. This has marginalized medicine boards from contributory oversight, thus circumventing any arguments over practice parameters. The scope-of-practice dispute is further complicated by the existence of dual-degree oral and maxillofacial surgeons. CONCLUSIONS: With increasing demand for cosmetic surgical interventions, establishing scope-of-practice standards for single-degreed oral and maxillofacial surgeons is critically important. As physicians, the oral and maxillofacial surgery graduates of the dual M.D./D.D.S. degree programs have no such scope-of-practice restrictions. Furthermore, if plastic surgery is to effectively argue against expanded scope of practice for oral and maxillofacial surgeons, more objective data will be necessary.

Health-related impediments to learning among dental and oral surgery students.

Dental education is a challenging experience that places significant demands on students' intellectual, financial, and psychosocial well-being. Dental students who simultaneously experience physical illness, emotional upset, or interpersonal difficulty may be at greater risk of experiencing negative academic consequences. It is well documented that stress affects student learning, however, the impact of other health concerns on academic success is less understood. The purpose of this manuscript is to document the prevalence and perceived academic impact of 24 health concerns on the academic performance of a sample of 130 undergraduate dental students as measured by the National College Health Assessment (NCHA). Health concerns that were most prevalent among dental students were generally also perceived to be most detrimental to their learning. These included upper respiratory infections (cold, flu, sore throat), interpersonal concerns (concerns about a troubled friend or family member, and relationship difficulty), and mental health issues (depression/anxiety/seasonal affective disorder, and stress).

Factors predicting success in the Intercollegiate Membership of the Royal College of Surgeons (MRCS) examination: a summary for OMFS.

The Intercollegiate Membership of the Royal College of Surgeons (MRCS, parts A and B) is a mandatory examination for entry into higher surgical training in the UK. We investigated which factors predict success in both the written (Part A) and clinical (Part B) parts of the examination, and provide a summary for oral and maxillofacial surgeons (OMFS). All UK graduates who attempted both parts between 2007 and 2016 were included. There was a positive correlation between the scores in parts A and B (r=0.41, p<0.01). For Part A, men (odds ratio (OR) 2.78; 95% CI 1.83 to 4.19), white candidates (OR 1.70; 95% CI 1.52 to 1.89), and younger graduates (under 29years of age), were more likely to pass (OR 2.60; 95% CI 1.81 to 3.63). Foundation year one (FY1) doctors had higher pass rates than all other grades (e.g. core surgical trainee 2 compared with FY1 OR 0.50; 95% CI 0.32 to 0.77). The number of attempts at Part A and the final score, as well as ethnicity and stage of training, were independent predictors of success in Part B. Candidates who did well in Part A were more likely to do well in Part B. Several independent predictors of success were identified, but only the stage of training and ethnicity were common predictors in both parts. Higher scores obtained by younger candidates might be relevant to OMFS trainees who take Part A after studying medicine as a second degree.

The American Association of Oral and Maxillofacial Surgeons Simulation Program.

Patient safety in dental anesthesia has been called into question in recent years. Simulation training has been proposed and developed as one possibility for increasing preparedness and training in cases of adverse events in dental anesthesia. This article presents an overview of the challenges of patient safety in dental anesthesia and how to address them with simulation training. The American Association of Oral and Maxillofacial Surgeons simulation program is unique in its potential to become a standardized, validated competency course with objective grading criteria, mastery-based cooperative learning model, and low facilitator-to-participant ratio, leading to a practical delivery cost structure.

3D Printed Surgical Simulation Models as educational tool by maxillofacial surgeons.

INTRODUCTION: The aim of this study was to evaluate whether inexpensive 3D models can be suitable to train surgical skills to dental students or oral and maxillofacial surgery residents. Furthermore, we wanted to know which of the most common filament materials, acrylonitrile butadiene styrene (ABS) or polylactic acid (PLA), can better simulate human bone according to surgeons' subjective perceptions. MATERIALS AND METHODS: Upper and lower jaw models were produced with common 3D desktop printers, ABS and PLA filament and silicon rubber for soft tissue simulation. Those models were given to 10 blinded, experienced maxillofacial surgeons to perform sinus lift and wisdom teeth extraction. Evaluation was made using a questionnaire. RESULTS: Because of slightly different density and filament prices, each silicon-covered model costs between 1.40-1.60 USD (ABS) and 1.80-2.00 USD (PLA) based on 2017 material costs. Ten experienced raters took part in the study. All raters deemed the models suitable for surgical education. No significant differences between ABS and PLA were found, with both having distinct advantages. CONCLUSION: The study demonstrated that 3D printing with inexpensive printing filaments is a promising method for training oral and maxillofacial surgery residents or dental students in selected surgical procedures. With a simple and cost-efficient manufacturing process, models of actual patient cases can be produced on a small scale, simulating many kinds of surgical procedures.

African Americans in Oral and Maxillofacial Surgery: Factors Affecting Career Choice, Satisfaction, and Practice Patterns.

PURPOSE: There are few data available on the experience of minority surgeons in the field of oral and maxillofacial surgery (OMS). Therefore, the purpose of this study was to 1) explore factors that contribute to African Americans choosing OMS as a career, 2) examine satisfaction among minority oral and maxillofacial surgeons with the residency application and training process, 3) report on practice patterns among minority oral and maxillofacial surgeons, and 4) identify perceived bias for or against minority oral and maxillofacial surgeons in an attempt to aid the efforts of OMS residency organizations to foster diversity. MATERIALS AND METHODS: A 19-item survey was sent to 80 OMS practitioners by use of information from the mailing list of the National Society of Oral and Maxillofacial Surgeons, an American Association of Oral and Maxillofacial Surgeons-affiliated organization. All surveys were sent by mail and were followed by a reminder mailing after 8 weeks. Responses returned within 16 weeks were accepted for analysis. RESULTS: Of the 80 mailed surveys, 41 were returned within the 16-week parameter, representing a return rate of 51%. Most of the minority surgeon respondents were married men with a mean age of 60 years who worked as private practitioners. Most respondents practiced on the eastern and western coasts of the United States. Exposure in dental school was the most important factor in selecting OMS as a specialty. Location and prestige were the most important factors in selecting a residency program. Most respondents reported that race did not affect the success of their application to a residency program and did not currently affect the success of their practice. However, 25 to 46% of participants experienced race-related harassment, and 48 to 55% of participants believed there was a bias against African Americans in OMS. CONCLUSIONS: Our data suggest that a substantial number of minority oral and maxillofacial surgeons subjectively perceive race-based bias in their career, although it does not appear to affect professional success.

The aim of this study was to undertake a review of modern methods of health care professionals training in the framework of continuous medical education profile introduced by the Ministry of Health. The paper presents the best IT practices of Central Research Institute of Dentistry and Maxillofacial Surgery in the training of dentists and maxillofacial surgeons aimed for the modernization of medical education.

Educational Utilization of Microsoft Powerpoint for Oral and Maxillofacial Cancer Presentations.

Electronic presentations have become useful tools for surgeons, other clinicians and patients, facilitating medical and legal support and scientific research. Microsoft® PowerPoint is by far and away the most commonly used computer-based presentation package. Setting up surgical clinical cases with PowerPoint makes it easy to register and follow patients for the purpose of discussion of treatment plan or scientific presentations. It facilitates communication between professionals, supervising clinical cases and teaching. It is often useful to create a template to standardize the presentation, offered by the software through the slide master. The purpose of this paper was to show a simple and practical method for creating a Microsoft® PowerPoint template for use in presentations concerning oral and maxillofacial cancer.

Integrating Patient Safety in the OMFS Curriculum: Survey of 4-Year Residency Programs.

PURPOSE: In 2003, the Institute of Medicine's (IOM) Committee on Health Professions Education Summit reported that students in all health professions should demonstrate competency in patient safety and performance improvement strategies to reduce the incidence of preventable medical errors. These recommendations have been adopted in medical, pharmacy, and nursing accreditation standards, yet not required in dental education. The purpose of this study was to explore if 4-year oral and maxillofacial surgery (OMFS) residency programs are aligned with other health professions in following the Institute of Medicine's recommendations to incorporate evidence-based patient safety training in the postgraduate curricula. METHODS: In October of 2012, a multiple choice questionnaire was sent to 27 four-year oral and maxillofacial surgery residency program directors via a link to Survey Monkey. A descriptive analysis of responses was performed upon achieving a 74% response rate. RESULTS: Ninety-five percent of the responding 4-year OMFS programs have integrated patient safety training in the residency curriculum. Seventy percent complete between 2 and 10 hours of safety training per academic year. Eighty percent of the programs apply human factors and system engineering theories in morbidity and mortality conferences, and 50% require residents to perform root cause analyses (RCA) of adverse events. CONCLUSIONS: The results of this study indicate that the majority of 4-year OMFS programs include patient safety education in the residency curriculum, although the duration of training and integration of acquired knowledge into practice varied among participants.

Learning Curve of a Minimally Invasive Technique for Transcrestal Sinus Floor Elevation: A Split-Group Analysis in a Prospective Case Series With Multiple Clinicians.

AIMS: To assess the learning curve of a minimally invasive procedure for maxillary sinus floor elevation with a transcrestal approach (tSFE) and evaluate the influence of clinician's experience in implant surgery on its outcomes. MATERIALS AND METHODS: Patients were treated by clinicians with different levels of experience in implant surgery and inexperienced with respect to the investigated tSFE technique. The initial (n = 13) and final (n = 13) groups treated by the expert clinician were compared for tSFE outcomes. Additionally, the high, moderate, and low groups (n = 20 each) treated by the expert, moderately experienced, and low experienced clinician, respectively, were compared. RESULTS: (1) No significant differences in clinical and radiographic outcomes were observed between initial and final groups; (2) high, moderate, and low groups showed substantial vertical augmentation in limited operation time with treatment outcomes being influenced by the level of experience in implant surgery. CONCLUSIONS: The investigated technique allows for a substantial vertical augmentation at limited operation times when used by different clinicians. The extent of sinus lift (as radiographically assessed) seems to be influenced by the clinician's level of experience in implant dentistry.

Predictors of blood loss during orthognathic surgery: outcomes from a teaching institution.

PURPOSE: The objective of the study was to correlate different orthognathic surgical procedures with operating time and blood loss, reported from an accredited resident training institution. METHODS: Ninety-five patient records were evaluated retrospectively. Individual blood volume, percent blood volume lost (BVL), and estimated blood loss (EBL) for each patient were recorded and correlated with operating time (OT). Statistics included independent t tests, one-way analysis of variance, and linear regression. RESULTS: The mean OT for all procedures was 203 min with mean blood loss 556 ml. Mean EBL for males was 676 ml versus 468 ml for females. Overall BVL was 12.4 %, while for males, BVL was 13.3 % compared to 11.8 % for females. For a single orthognathic procedure (n = 45), mean OT 145 min., EBL 414 ml, and BVL 9.0 %; two procedures (n = 41), mean OT was 239 min., EBL 659 ml, and BVL 15 %; three procedures (n = 9), mean OT 328 min, EBL 793 ml, and BVL was 17 %. CONCLUSION: Examination of individual procedures suggests a shorter OT for Le Fort I procedures with slightly greater EBL. Concomitant orthognathic procedures are associated with greater OT and EBL. Blood volume should be calculated for male and female patients separately. Percent BVL can be predicted based on OT using a basic equation.
