Although the healing of extraction sites is generally a rapid and uncomplicated process, delayed healing or overt infection of recent extraction sockets may involve a variety of causes and the clinician must be aware pre-operatively of both local and systemic influences. Retarded or non-healing extraction sites always require investigation. This paper looks broadly at the subject of non-healing extraction sites and reports an unusual case involving an inverted papilloma of the maxillary antrum. To the authors' knowledge this is the first reported case of an antral papilloma causing delayed extraction wound healing.

A case report of aneurysmal bone cyst of the mandible in a twenty-four year old woman is presented. Although uncommon, such lesions should be considered in the differential diagnosis of radiolucent lesions of the jaws. The Occurrence of this lesion in the jaws has not been previously reported in the Australian dental literature.

Various factors have resulted in an increased demand for relatively minor surgical treatment requiring general anaesthesia to be carried out in the surgery on an outpatient basis. Previous studies have reported significant decreases in oxygen saturation in patients under intravenous sedation and in patients under general anaesthesia. This study examined the levels of oxygen saturations in outpatients undergoing oral surgical procedures under general anaesthesia. The results confirm the value of pulse oximetry and suggest that this mode of monitoring and the administration of supplemental oxygen be routinely utilised during the recovery period.
