Impact of Traumatic Injuries to Primary Teeth on the Development of Permanent Dentition: Findings From a Retrospective Cohort.

ABSTRACT:

Objective

This retrospective cohort study aimed to analyze the occurrence of sequelae in permanent teeth resulting from traumatic injuries to primary dentition among children treated over a 14-year period at a specialized Dental Trauma Center.

Methods

Data from 140 children with complete records on trauma and sequelae were evaluated. Poisson regression was applied to calculate relative risks (RR) with 95% confidence intervals (CI).

Results

Out of the 244 primary teeth affected by trauma, 81 (33.2%) exhibited sequelae in their permanent successors. The majority of sequelae were mild, with enamel discoloration being the most common type. Intrusive luxation and avulsion were the main causes of sequelae. Factors influencing sequelae included age, trauma location, and trau
