Abstract
The aim of this article was to carry out a prospective audit on a convenience sample of all new patients referred to the toothwear clinic at Cardiff University Dental Hospital to establish the prevalence of undiagnosed periapical pathology.

Article
Toothwear is a clinical problem that is frequently encountered in dental practice and prevalence values in adult patients of up to 82% have been reported.1 The most recent Adult Dental Health Survey (1998) reported that 11% of adults had anterior toothwear with extensive involvement of dentine.2 Toothwear is thought to be multifactorial in nature and may be caused by a combination of attrition, abrasion and erosion.3 Attrition is caused by tooth to tooth contact, both occlusally and interproximally, and is often associated with tooth clenching and grinding habits. Abrasion is caused by abrasive particles introduced into the mouth as part of the diet. A good example is the abrasive particles found in toothpaste.
Dental erosion may be defined as an irreversible loss of dental hard tissues due to a chemical process without the involvement of micro-organisms.4 This process may be caused by either extrinsic or intrinsic agents. Extrinsic agents include:
