Dens Evaginatus and Dens Invaginatus in Dilacerated Maxillary Lateral Incisor Diagnosed Using Cone Beam Computed Tomography - A Case Report and Review of Literature.

ABSTRACT

INTRODUCTION: Dens invaginatus (DI) and Dens evaginatus (DE), the developmental anomalies affecting the morphology of the tooth structure are extremely rare to occur. DI occurs because of invagination of a crown into dental papillae. DE is a tubercular emergence from occlusal surfaces of posterior teeth and lingual surfaces of anterior teeth. The two anomalies on separate teeth are frequently mentioned, but their co-occurrence in a single tooth is a rare entity. PATIENT CONCERNS A 20-year-old male patient presented with the rare combination of DE and DI on a dilacerated maxillary right lateral incisor diagnosed using cone beam CT. Treatment The patient was managed conservatively and is undergoing fixed orthodontic treatment for malocclusion. Despite its uniqueness, very few localized cases have been documented. TAKEAWAY LESSONS These anomalies act as an etiological factor for several dental problems for neighboring & opposing tooth. Early diagnosis of such anomalies should be done so that prophylactic management can be initiated.
