Long-Term Sequelae of Primary Tooth Injuries on Permanent Successors: A Case Series

Trauma to the primary dentition is a common occurrence in early childhood and poses a significant risk to the developing permanent successors due to their close anatomical relationship. The sequelae may have delayed presentation, where symptoms may arise even years after the trauma in the form of developmental disturbances to the permanent teeth. This case series presents five children who presented with developmental sequelae to their permanent successors after traumatic injury to their predecessor primary teeth. The presentations in the cases included enamel hypoplasia, crown dilaceration, delayed eruption, impaction, odontome-like formations, and pulpal pathologies, which required multidisciplinary management including endodontic, orthodontic, surgical, and restorative intervention based on the individual presentation of the developmental disturbance. Primary tooth trauma can have diverse sequelae in the permanent successors with delayed presentation, and requires multidisciplinary management, early diagnosis, and long-term follow-up to ensure the best functional and esthetic outcomes.
