Abstract
BACKGROUND/AIM
Clinical and radiographic sequelae are common following traumatic dental injuries to primary teeth. The aim of this systematic review was to assess the prevalence of such sequelae.
MATERIALS AND METHODS
Searches were conducted in the PubMed, Scopus, Embase, Web of Science, and BBO/LILACS databases as well as the gray literature. The outcome of interest was the prevalence of the most common sequelae following traumatic dental injuries to anterior primary teeth. Observational studies that evaluated such sequelae were included. Data were extracted, and methodological quality was appraised using the Joanna Briggs Institute Critical Appraisal Checklist for Studies Reporting Prevalence Data. The number of sequelae per tooth and the total number of teeth evaluated in each study were considered to calculate pooled prevalence rates with 95% confidence intervals (CI). The quality of the evidence was determined using the GRADE approach.
RESULTS
Twenty-five articles were included in this systematic review and meta-analysis. The prevalence of each complication in descending order was as follows: 39.7% crown discoloration (95% CI: 29.52-50.32), 24.3% pulp necrosis with infection (95% CI: 17.34-32.06), 16.2% periapical radiolucency (95% CI: 8.88-25.49), 15.9% premature tooth loss (95% CI: 9.93-23.15), 14.8% pulp canal obliteration (95% CI: 8.46-22.73), 11.9% pathological root resorption (95% CI: 7.68-16.98), 7.1% abscess/fistula (95% CI: 4.4-10.6), and 1.8% ankylosis (95% CI: 0.82-3.17). The certainty of the evidence was very low.
CONCLUSIONS
Crown discoloration was the most common sequela in injured primary teeth, but this should be interpreted with caution due to the very low certainty of the evidence. Considerable variation was found in the prevalence of each sequela.
