Unilateral Dens Invaginatus in Immature Maxillary Central Incisor: A Case Report

Introduction: Dens invaginatus (DI) is a rare developmental malformation occurring as a result of the invagination of the enamel organ. The aetiology of this anomaly remains unclear. However, the knowledge of classification and anatomical variations of teeth with DI are very significant for the best treatment. The most commonly affected tooth is the maxillary lateral incisor. The treatment varies depending on the severity of the case. This paper presents a case of DI on an immature permanent maxillary central incisor.

Case Report: An eight-year-old healthy Malay girl came to the paediatric dental clinic for regular dental check-up. The intra-oral examination revealed presence of deep pit on the permanent maxillary left central incisor. The radiograph showed the presence of invaginatus confined within the crown indicating DI. The tooth partially erupted with the open apex. The best treatment option was the placement of fissure sealant on the affected tooth.

Conclusions: A thorough examination, early diagnosis, and proper treatment are important to prevent any dental complication that may associate with this anomaly.
