Dentinogenesis Imperfecta in Primary Dentition: Case Report

Background and Clinical Significance: Dentinogenesis imperfecta is a hereditary dentin disorder that compromises tooth structure, esthetics, and function.
Case Presentation: We report the case of a 1.5-year-old female presenting with generalized discoloration of the primary dentition and intermittent sensitivity to thermal stimuli. The diagnosis of dentinogenesis imperfecta was established based on characteristic clinical features, radiographic findings, and a positive family history. The patient was followed longitudinally from 2020 to 2025, with documentation of diagnostic findings, radiographic changes, therapeutic interventions, and outcomes. Management included placement of composite veneers on the maxillary incisors for esthetic rehabilitation and sealants on second primary molars as a preventive measure. Although various management approaches have been described in the literature, evidence regarding optimal strategies and long-term outcomes in the primary dentition remains limited. This case highlights the occurrence of asymptomatic periapical pathology and root resorption despite minimal clinical symptoms, underscoring the challenges of relying on symptom-based assessment alone.
Conclusions: Early diagnosis, regular radiographic monitoring, and individualized, risk-based treatment planning are essential in managing dentinogenesis imperfecta. This case emphasizes the importance of recognizing asymptomatic disease progression and integrating psychosocial considerations into comprehensive care.
