Crown Fracture of an Unerupted Incisor in a Young Child: Case Report and Restorative Protocol

Deise Kamanski et al. Int J Clin Pediatr Dent. 2022 Sep-Oct.

Abstract

Aim: This case report describes a protocol for restoring a crown fracture of an unerupted permanent incisor in a child.

Background: Crown fractures are an important concern in pediatric dentistry due to the negative impact on oral health-related quality of life (OHRQoL) in children and adolescents resulting from functional limitations as well as consequences related to social and emotional well-being.

Case description: An enamel and dentin fracture of the crown of unerupted tooth 11 due to direct trauma is being presented in a 7-year-old girl. The restorative treatment involved minimally invasive dentistry, including computer-aided design (CAD)/computer-aided manufacturing (CAM) technology and direct resin restoration.

Conclusion: The treatment decision was essential for maintaining pulp vitality and continued root development, as well as ensuring esthetic and functional results.

Clinical significance: Crown fracture of an unerupted incisor may occur in childhood, requiring a long-term clinical and radiographic follow-up. Predictable, positive, and reliable esthetic outcomes can be achieved using CAD/CAM technology combined with adhesive protocols.
