Background: A dental injury is an emergency requiring immediate treatment to reduce pain and restore the tooth's function and aesthetics. The maxillary central incisors are the teeth most commonly affected by trauma. Some articles have reported that 58.6% of patients aged 7-15 years old have sustained dental injuries in the form of maxillary incisor crown fractures. This may occur before or after root formation is complete, and the results may range from pulp inflammation to pulp necrosis. A class IV Ellis fracture describes a traumatized tooth that has become non-vital, with or without the loss of the tooth structure. It is important to determine the pulp vitality and root development stage in order to create a treatment plan. Case report: This paper describes the management of a class IV Ellis tooth fracture in a permanent central incisor via crown restoration with a fiberglass post after an endodontic procedure in a 14-year and 8-month-old patient. Discussion: Non-vital traumatized teeth require root canal treatment followed by crown and post core restoration for intra coronal retention. A fiberglass post and resin is an option in this case because of its advantages when compared to a metal post, including good aesthetics, adhesion to the dentin (mono block dentin-post-core system), and modulus of elasticity, which is almost the same as that of dentin. It can distribute pressure equally in the root, reducing the risk of fracture. Conclusion: The 14-week follow-up examination showed that the restoration remained in place and was successful.
