Panoramic radiography has become a commonly used imaging modality in dental practice and can be a valuable diagnostic tool in the dentist's armamentarium. However, the panoramic image is a complex projection of the jaws with multiple superimpositions and distortions which may be exacerbated by technical errors in image acquisition. Furthermore, the panoramic radiograph depicts numerous anatomic structures outside of the jaws which may create additional interpretation challenges. ⋯ This article will describe how osseous structures, soft tissues, air spaces and ghost shadows contribute to the final panoramic image. A systematic and repeated approach to examining panoramic radiographs, which is recommended to ensure that critical findings are not overlooked, is also outlined. Examples of challenging interpretations, including variations of anatomy, artefacts and disease, are presented to illustrate these concepts.

Randomized Controlled Trial Comparative StudyInhaled methoxyflurane (Penthrox) sedation for third molar extraction: a comparison to nitrous oxide sedation.
The aim of this study was to evaluate the use of inhaled methoxyflurane (Penthrox) in the reduction of dental anxiety in patients undergoing mandibular third molar removal in a specialist surgical suite and compare it to the conventional nitrous oxide sedation. ⋯ The Penthrox Inhaler can produce a comparable sedation to that of nitrous oxide for the surgical extraction of third molars under local anaesthesia.

Simulation of medical emergencies in dental practice: development and evaluation of an undergraduate training programme.
The evidence available suggests that many dentists on graduation do not feel competent managing medical emergencies; a problem requiring improved undergraduate training. This study developed a comprehensive simulation based training programme for final year undergraduate dental students and assessed student attitudes towards training. ⋯ Realistic simulation training in management of medical emergencies for dental students is an effective adjunct to traditional lecture style teaching. Given the importance of this subject, this mode of training would benefit students if incorporated into undergraduate dental courses.

Case ReportsManagement of third molar removal with a single dose of recombinant Factor IX (BeneFIX) and local measures in severe haemophilia B.
Patients with inherited bleeding disorders have historically had factor cover for oral surgery. Factor support is expensive, time consuming and places the patient at a potential risk of blood-borne diseases. This case describes the use of a significant reduction in factor support for a severe haemophilia B patient having third molars surgically removed. ⋯ Oral surgery may be performed on patients with inherited bleeding disorders using minimal factors and local haemostatic measures. A study of this patient population has commenced at The Alfred Hospital.
