REVIEWS

Current concepts in oral cancer Over 750 new intra-oral squamous cell carcinomas are registered in Australia each year. In this article, the authors review the epidemiology, aetiology, genetics and spread of intra-oral squamous cell carcinoma. The mechanisms of field cancerization are discussed. The prevention of intra-oral squamous cell carcinoma is highlighted and future treatments are presented.

Dental cervical lesions associated with occlusal erosion and attrition Acid demineralization of teeth causes occlusal erosion and attrition, and shallow and wedge-shaped cervical lesions putatively involving abfraction. From 250 patients with tooth wear, 122 with cervical lesions were identified. From epoxy resin replicas of their dentitions, associations of occlusal attrition or erosion or no wear with cervical lesions were recorded at 24 tooth sites (total 2928 sites).

SCIENTIFIC ARTICLE

Incidence of complicated healing and osteoradionecrosis following tooth extraction in patients receiving radiotherapy for treatment of nasopharyngeal carcinoma A group of 43 patients requiring tooth extraction after radiotherapy for nasopharyngeal carcinoma (NPC) was studied retrospectively to determine the incidence of post-extraction complications. It was found that because of the method used in the delivery of radiation, extraction of maxillary posterior teeth resulted in the greatest risk of complications (28.9 per cent), including a 10.5 per cent risk of osteoradionecrosis (ORN). Based on the findings, a protocol was established for the dental care of such patients.

CLINICAL REPORTS

Custom-made titanium mandibular reconstruction tray Reconstruction of the mandible after ablative surgery can be achieved by using preformed trays or trays formed from models produced by computer-assisted modelling systems. The former presents difficulty in matching the required facial contour, jaw relationship and condylar position; while the latter is expensive. This paper presents a simple and inexpensive method of fabricating a custom-made titanium bone grafting tray.

Integrating the surgical and prosthodontic stages of implant therapy with a sterile implant position registration A new implant position registration technique utilizing an autoclavable thermoplastic material is described. This technique, which has been in use since 1994, allows the clinician to fabricate a provisional restoration for insertion at stage II surgery to enhance the soft tissue contour and the aesthetics of the final restoration.

CASE REPORT

Metastatic neuroblastoma of the mandible mimicking osteogenic sarcoma radiologically. Case report This paper presents a case of a neuroblastoma of the adrenal gland metastazing to the mandible of a 21 month old infant, which presented radiographically as the so-called ‘sun-ray’ appearance, characteristic of osteogenic sarcoma.
