Pulp Canal Obliteration Following Trauma in Primary Teeth

Abstract

Introduction: Dystrophic calcification in the root canal is a progressive process that occurs due to the deposition of tertiary dentin in response to trauma, mainly after luxation injuries. It generally indicates viable pulp tissue and may present with color changes in the dental crown, causing concern for parents or guardians. Therapeutic approaches for this condition range from preventive endodontics to clinical monitoring to avoid complications. Objective: to review the current scientific literature to identify the diagnosis and appropriate management of dystrophic pulp calcification after trauma in deciduous teeth. Literature Review: Pulp canal obliteration is common in children who have suffered dentoalveolar trauma in the deciduous dentition, affecting both sexes equally. Studies show that pulp calcification does not affect the exfoliation or eruption of permanent successors. Radiographic follow-up is essential to identify and prevent adverse outcomes. Color changes and calcification do not necessarily indicate pulp necrosis; other pathological signs must be considered. Conclusions: After trauma in deciduous teeth, proper diagnosis and management are crucial, with guidance for parents on post-trauma clinical signs. Recommendations: Despite the good prognosis, management of pulp canal obliteration includes periodic follow-up with clinical and radiographic examinations until the eruption of permanent successors
