Abstract

The purpose of this paper is to report the case of an 8-year-old female with occlusal interferences involving the permanent maxillary right central incisor (PMRCI) due to a Type 1 dens evaginatus, also known as a talon cusp (TC), causing displacement of the affected tooth. Clinical concerns related to TCs include occlusal interferences and increased risk for dental injury, displacement of the affected tooth, caries, tongue irritation and esthetic concerns. The TC in this report was reduced periodically over two months. Following each reduction, 5% topical sodium fluoride varnish was applied as a desensitizing agent. Upon completion and removal of the TC, sealant (Ultra Seal XT R plus TM, Ultradent Products, Inc. USA) material was applied to the lingual surface of the affected tooth. The patient was evaluated five weeks after treatment completion, during which time, no clinical signs or symptoms related to the reduction were reported.
