Radiographic Predictors of Postoperative Inferior Alveolar Nerve Injury in Mandibular Third Molar Surgery.

Background: Cone-beam computed tomography (CBCT) provides additional 3-dimensional information on the relationship between the mandibular third molar (M3M) and the inferior alveolar nerve (IAN). As such, CBCT is being increasingly utilized in preoperative M3M assessment.

Purpose: The purpose of the study was to compare the radiographic findings on panoramic and CBCT and their association with postoperative IAN paresthesia.

Reasons for why Medical Students Prefer Specific Sleep Management Strategies.

Objectives: Insomnia symptoms are common among medical students. This study explored the perspectives of medical students about which sleep management strategies to use.

Methods: Medical students responded to an online survey on their thoughts about the use of various sleep management strategies.

Surgical accuracy of CAD/CAM splints using virtual surgical planning in orthognathic surgery: policy implications for healthcare in Australia.

Background: This study examines post-surgical outcomes of maxillary position using virtual surgical planning (VSP) with computer designed and manufactured surgical splints, without the use of costly patient specific implants (PSI), in the treatment of routine nonsyndromic orthognathic patients. The cost of these personalized medical devices and their impact in the setting of cranio-maxillofacial surgery is currently under review by The Department of Health and Aged Care in Australia.

Methods: This is a single-centre retrospective analysis of 49 patients who underwent bimaxillary orthognathic surgery by a single surgeon at Epworth Richmond Hospital (Victoria, Australia) over a period spanning 2016 to 2020.

Sleep Management Strategies Among Medical Students At the University of Otago.

Objectives: We aim to investigate factors which might affect the sleep of medical students, and how they currently manage their sleep.

Methods: An online survey was sent to medical students at the University of Otago.

Results: After adjusting for gender, ethnicity and age, depressive symptoms (: odds ratio (OR) = 6.

Osteoarthritis of the temporomandibular joint: a review of aetiology and pathogenesis.

The aim of this review was to assess the level of evidence for genetic, biological, and functional predictive and predisposing factors for end-stage temporomandibular joint arthritis within the published literature. A comprehensive review based upon PRISMA guidelines was performed from all literature relevant to the topic. Case series and animal studies were included given the rare nature of the disease and goal of finding root-cause predictive factors.

Degree of Compression of the Inferior Alveolar Canal on Cone-Beam Computed Tomography and Outcomes of Postoperative Nerve Injury in Mandibular Third Molar Surgery.

Purpose: Cone-beam computed tomography (CBCT) offers the advantage of a 3-dimensional representation of the anatomic relationship of the mandibular third molar tooth and the inferior alveolar canal (IAC), as compared to a panoramic radiograph. We hypothesized that a novel method of categorizing the degrees of compression of the IAC were reliable predictors for postoperative nerve injuries.

Methods: We conducted a retrospective analysis of the outcomes in third molar surgery for patients who obtained a CBCT scan in additional to a plain film radiograph over a 12 months period and underwent surgical removal of their mandibular third molars; 257 consecutive patients were identified, and 416 mandibular third molars were surgically removed.

Preference for sleep management strategies among prostate cancer patients: An Aotearoa/New Zealand perspective.

Introduction: Many men with prostate cancer (PCa) experience insomnia symptoms post-treatment. We explore here PCa patients' preference for strategies to manage their sleep.

Patients And Methods: A brief online survey was launched on Facebook and promoted by Prostate Cancer Foundation New Zealand.

The panoramic dental radiograph for emergency physicians.

Dental emergencies are common reasons for presenting to hospital emergency departments. Here, we discuss the panoramic radiograph (orthopantomogram (OPG, OPT) as a diagnostic tool for the assessment of mandibular trauma and odontogenic infections. In this article, we review the radiographic principles of image acquisition, and how to conduct a systematic interpretation of represented maxillofacial anatomy.

Spontaneous bilateral osteonecrosis of the mandible in a bisphosphonate-naive patient.

Medication-related osteonecrosis of the jaw is a well-described, yet poorly understood disease of bone that is commonly associated with antiresorptive and antiangiogenic drugs. We report a case of spontaneous bilateral osteonecrosis of the mandible in a patient with no previous exposure to either.

Clinical uses of botulinum toxin A in smile aesthetic modification.

In this article we review the pharmacodynamics of commercially available preparations of botulinum toxin type A, and discuss the potential uses of the drug in smile modification. A major emphasis is placed on applications relevant to modern dental practice, and to the complications arising from its use. Botulinum toxin A, when applied correctly, is a safe and effective means of achieving aesthetic smile modification, with limited data on any demonstrable long-term adverse effects.

Orbital fractures in the emergency department: a review of early assessment and management.

Orbital fractures are a common, potentially vision-threatening presentation to an emergency department. Appropriate early management and referral by the emergency medicine practitioner has a significant role in preventing cosmetic and functional sequelae of orbital trauma. In this paper, we review the emergency, non-specialist management of traumatic injuries to the orbit.

Unusual complication of repair of fractured mandibular angle.

Internal fixation with miniplates remains an accepted and reliable approach to the management of mandibular fractures, and erosion through the oral mucosa is a well-recognised long-term complication. We report a case of erosion of a miniplate through the skin 5 years after internal fixation of a fracture of the left mandibular angle.

Multicentric Castleman's Disease in a Hepatitis C-Positive Intravenous Drug User: A Case Report.
