A case is presented of extreme loss of tooth substance, most probably as a result of dentifrice abrasion. The lesions resulted in many instances of pulpal death and periapical pathosis. In most instances, an opening into the pulp chamber could not be demonstrated using an explorer. In two instances, an opening into the pulp chamber was present and probable. This communication with the oral cavity resulted in pulpal pathosis and an accompanying periapical lesion. In most cases of dental abrasion and erosion, or both, pulpal pathosis and periapical pathosis do not occur because of the ability of the pulp to lay down dentin as the pulp recedes. The findings in this case are not typical.
本文报告一例牙齿物质大量丧失的病例，很可能是由牙膏磨损所致。这些病变导致了许多牙髓坏死和根尖周病变的情况。在大多数情况下，使用探针无法探查到牙髓腔的开口。在两例病例中，存在通向牙髓腔的开口且可能性较大。这种与口腔的连通导致了牙髓病变及伴随的根尖周病变。在大多数牙齿磨损和侵蚀或两者皆有的病例中，由于牙髓在退缩时能够形成牙本质，所以不会发生牙髓病变和根尖周病变。该病例的发现并不典型。
