Abstract
INTRODUCTION Benzodiazepines such as midazolam are widely used to moderately sedate patients during impacted wisdom tooth extraction to reduce anxiety in outpatient surgery. This present protocol was designed to determine whether continuous intravenous remimazolam, a new ultrashort-acting benzodiazepine, produces superior postoperative recovery quality to that of midazolam in patients undergoing extraction of impacted wisdom teeth. METHODS AND ANALYSIS This study is a multicentre randomised controlled trial conducted at Peking Union Medical College Hospital, Beijing Anzhen Hospital and Beijing Shijitan Hospital in China. Approximately 150 participants undergoing extraction of impacted mandibular wisdom teeth will be randomly allocated to two groups (remimazolam and midazolam). The participants will be administered standard interventions to ensure they achieve a sedation level of III on the Ramsay sedation scale during the treatment. Preoperative and anaesthesia management and surgical techniques will be standardised for all participants. The primary outcome is recovery time for complete alertness and the secondary outcomes are anterograde amnesia during and after surgery, and interruption during operation for poor compliance or safety concerns. ETHICS AND DISSEMINATION This study has been approved by the Ethics Review Committee of Peking Union Medical College Hospital (approval number: ZS-3142), Beijing Anzhen Hospital (approval number: KS2022082) and Beijing Shijitan Hospital (approval number: 2023-4). TRIAL REGISTRATION NUMBER NCT05350085.

Abstract
Entering into surgical academia can seem a daunting prospect for an oral and maxillofacial surgery (OMFS) trainee. However, the streamlining of academic training by the NIHR to create the integrated academic training (IAT) pathway has simplified academic training and more clearly defined academic positions and entry points for trainees. In this article we review the current NIHR IAT pathway and the various grades and entry points available to OMF surgeons, both pre- and post-doctoral. We highlight the unique challenges facing OMF trainees and provide advice and insight from both junior and senior OMFS academics. Finally, we focus on the planning and application for a doctoral research fellowship - discussing funding streams available to OMF surgeons.

Abstract
INTRODUCTION Endodontic microsurgery is a very important technique for preserving the natural teeth. The outcomes of endodontic microsurgery largely depend on the skill and experience of the operators, especially for cases in which the apices are located far away from the labial/buccal cortical bone. A dynamic navigation system (DNS) could provide a more accurate and efficient way to carry out endodontic microsurgery. This study is devoted to comparing the clinical outcomes of the DNS technique with those of the freehand technique. METHODS AND ANALYSIS Sixteen patients will be randomly assigned to one of two groups. For the experimental group, the osteotomy and root-end resection will be performed under the guidance of dynamic navigation. For the control group, these procedures will be performed freehand by an endodontist. The required time to perform these procedures will be used to evaluate the efficiency of the DNS technique. A Visual Analogue Scale will be used to evaluate pain at 1, 3 and 7 days after endodontic microsurgery. Preoperative and postoperative cone beam CT scans will be obtained to evaluate the accuracy of the DNS technique. The global coronal deviations, the apical deviations and the angular deflection will be measured. The root-end resection length deviation, the root-end resection angle deviations, the extent of the osteotomy and the volume change of the buccal cortical bone will also be measured. Periapical radiographs will be obtained to evaluate the outcome at 1 year after microsurgery. The time to execute the study, including follow-ups, will last from 1 June 2022 to 31 December 2025. ETHICS AND DISSEMINATION The present study has received approval from the Ethics Committee of Peking University School and Hospital of Stomatology. The results will be disseminated through scientific journals. TRIAL REGISTRATION NUMBER ChiCTR2200059389.

Abstract
OBJECTIVES We aimed to evaluate the patient-reported outcome measures (PROMs) of dental implant surgeries and analyse the associated indicators. DESIGN A cross-sectional study design was used. SETTING Department of Oral Implantology, Hospital of Stomatology, Wuhan University (May 2020-April 2021). PARTICIPANTS Participants with missing teeth in need of implant-supported rehabilitation. INTERVENTIONS Dental implant placement and/or bone augmentation procedures. PRIMARY AND SECONDARY OUTCOME MEASURES The primary outcome was discomfort on postoperative day 1, measured using a numerical rating scale (NRS). Secondary outcomes included pain and anxiety during surgery; discomfort on postoperative days 3, 7 and 14; and post-surgical complications. RESULTS A total of 366 participants were included, of which 288 (78.7%) and 328 (89.7%) reported no to mild pain and anxiety (NRS 0-3) during surgery, respectively. The proportion of patients reporting discomfort decreased from postoperative day 1 (57.7%) to day 3 (36.1%) and day 7 (17.5%). The most frequent postoperative adverse events were pain and swelling. Patient-related factors (age, sex, smoking, alcohol consumption, history of periodontitis, and pain and anxiety during surgery) and surgery-related factors (type and extent of surgical procedure) were analysed. The factors associated with the severity of discomfort after surgery included alcohol consumption, pain perception during surgery, bone augmentation procedures and age (p<0.05). Similarly, the factors associated with the duration of discomfort included alcohol consumption, pain perception during surgery and age (p<0.05). CONCLUSIONS PROMs related to dental implant surgeries can be predicted using certain risk indicators. Alcohol consumption, pain during surgery and age were associated with discomfort following dental implant surgery.

Abstract
Background Despite the integral role of cephalometric analysis in orthodontics, there have been limitations regarding the reliability, accuracy, etc. of cephalometric landmarks tracing. Attempts on developing automatic plotting systems have continuously been made but they are insufficient for clinical applications due to low reliability of specific landmarks. In this study, we aimed to develop a novel framework for locating cephalometric landmarks with confidence regions using Bayesian Convolutional Neural Networks (BCNN). Methods We have trained our model with the dataset from the ISBI 2015 grand challenge in dental X-ray image analysis. The overall algorithm consisted of a region of interest (ROI) extraction of landmarks and landmarks estimation considering uncertainty. Prediction data produced from the Bayesian model has been dealt with post-processing methods with respect to pixel probabilities and uncertainties. Results Our framework showed a mean landmark error (LE) of 1.53 ± 1.74 mm and achieved a successful detection rate (SDR) of 82.11, 92.28 and 95.95%, respectively, in the 2, 3, and 4 mm range. Especially, the most erroneous point in preceding studies, Gonion, reduced nearly halves of its error compared to the others. Additionally, our results demonstrated significantly higher performance in identifying anatomical abnormalities. By providing confidence regions (95%) that consider uncertainty, our framework can provide clinical convenience and contribute to making better decisions. Conclusion Our framework provides cephalometric landmarks and their confidence regions, which could be used as a computer-aided diagnosis tool and education.

Abstract
Novel corona virus, named as SARS-Cov-2 is the seventh coronavirus causing Corona Virus Disease (COVID-19) in human. It is one of the very few rare events in history of mankind to affect public health at such an enormous scale globally. Whole world is on standstill with this outbreak, which was declared pandemic by WHO in March 2020. All healthcare workers and especially the ones working in vicinity of nasal/oral regions are high risk group to be infected by this airborne virus. Recently, a 62 years old ENT specialist Liang Wudong died while treating patients with COVID in Wuhan city. Numerous reports of health care workers getting infected while serving their patients are coming from all parts of world. As health care providers are struggling to ensure safety and survival of people, their own wellbeing and preventing further spread of infection is also their responsibility. As head and neck surgical specialties are uniquely vulnerable to infection transmission, this communication highlights various instructions and suggestions given by International & National health agencies to safeguard the patient, surgical team, health workers and community. Though the decision regarding treatment is surgeon’s discretion, we hope these guidelines will help in decision making.
