IMPACT OF DENTAL TRAUMA IN PRIMARY DENTITION ON THE DEVELOPMENT OF THE PERMANENT TOOTH GERM

Abstract

Introduction: Dental trauma in primary dentition is a common childhood occurrence that can lead to severe and irreversible repercussions on the permanent successor's germ due to the close anatomical relationship between these structures. Objective: To analyze the impact of dental trauma in childhood and its repercussions on the development of the permanent tooth germ. Methodology: Descriptive literature review conducted in PubMed, SciELO, and VHL databases (2021–2026). Retrospective studies, systematic reviews, and clinical guidelines relating primary tooth injuries to sequels in successors were selected. Results: The severity of the sequel is directly linked to the type of trauma and the child's age. Intrusions and luxations are the injuries with the highest potential for damage to the permanent tooth. The main identified changes include enamel hypoplasia, discoloration, root dilacerations, and eruption disturbances. Discussion: There is a consensus that longitudinal follow-up is essential, as many sequels only manifest years after the trauma during the successor's eruption. Early intervention and radiographic monitoring are decisive for a better prognosis. Conclusion: Trauma in primary dentition is a significant risk factor for dental development anomalies. Immediate diagnosis and parental guidance are fundamental to minimizing functional and aesthetic complications in the permanent dentition.
