Case Report: Case report: Rapidly progressing tooth wear dominated by intrinsic and extrinsic erosion.

Tooth wear is multi-factorial presenting as a combination of abrasion, attrition, and erosion. This case report represents a case of combined tooth wear in a 46-year-old Indo-Trinidadian male, with a predominant erosive component with both the clinical signs and features of intrinsic and extrinsic erosion. This patient case is unique since the wear predominated by dental erosion has occurred rapidly evidenced by the physical clinical appearance of a lack of compensation and the upper left premolars and molars relatively unaffected by the overall effects of tooth wear. This lack of compensation, where opposing teeth have not supra-erupted to maintain inter-arch stability, and the maintenance of occlusal vertical dimension on the left due to the non-worn posterior maxillary teeth, provides the benefit of simplifying subsequent restorative management. The medical and diet history corroborates the diagnoses of intrinsic and extrinsic erosion respectively. Complications noted with rapid tooth wear, such as dentine sensitivity and pulpal necrosis are known sequelae of tooth wear however the patient presented in this case report shows a concomitant high caries experience and poor oral hygiene. Cases such as the one presented here require not only comprehensive dental management, utilizing a restorative approach but also medical referral for confirmation of a diagnosis and management of gastroesophageal reflux disease. Inherent to the management of this patient should be a multidisciplinary medical and dental approach, with confirmation and management of the cause of the intrinsic erosion as well as restorative dental management, together with dietary counseling to mitigate the effect of intrinsic and extrinsic sources of acid on dental hard tissue. A key lesson learned from this case is the importance of history and targeted questioning when trying to determine the cause of tooth wear dominated by intrinsic and extrinsic erosion.
