Background: Talon cusp is a rare anomaly projecting from the dento-enamel junction to a variable distance towards the incisal edge of an anterior tooth. Hyperactivity of the enamel organ during morphodifferentiation has been accredited to its formation. When it occurs, the effects are mainly aesthetic and functional and so early detection and treatment is essential in its management to avoid complications. Case presentation: An unusual case of talon cusp on the lingual aspect of a mandibular central incisor with fusion is reported. Conclusion: The management and treatment outcome of talon cusp depends on the size, presenting complications and patient cooperation.
Dens Invaginatus (DI) is a rare developmental anomaly, which presents as an infolding of enamel and dentine extending into the pulp chamber and sometimes into the root. The aim of this case report was to describe its radiographic findings, to emphasize the inexplicable morphology. Considering the likelihood of an early pulpal involvement and the chronic periapical lesions often associated with this anomaly without any clinical symptoms, dens invaginatus is clinically significant. Difficulties are encountered during the endodontic treatment, owing to the complex root canal anatomy. Therefore, a proper diagnosis and evaluation of the anomaly is essential to save the involved tooth.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
