We report a case in which the extraction of an upper second molar was complicated by a maxillary tuberosity fracture. Delivery of the tooth and bone fragment under local anaesthesia was unable to be achieved because of pain, brisk bleeding and tethering by the lateral and medial pterygoid muscles. The eventual removal of the fragment under general anaesthetic required the control of haemorrhage deep within the infratemporal fossa. When this complication is recognised by the general dentist the maxillary tuberosity should not be removed and the patient referred to a specialist unit.
Among the most important factors in a thorough clinical examination is the dentist's ability to recognize and make distinctions among normal oral structures, variations of normal structures, and pathologic entities. The practitioner's diagnostic acumen is essential to this process and is a skill gained and refined by clinical experience and continuing education. In this introductory article, the authors describe normal entities, anomalies, and benign soft tissue lesions of interest to the clinician. For presentation, these structures are organized according to their location within the oral cavity.
