Zaror C, et al. - The effect of traumatic dental injuries (TDIs) on the oral health-related quality of life (OHRQoL) of preschoolers and schoolchildren was evaluated, by synthesizing the available evidence. This meta-analysis concluded that TDIs had a negative effect on OHRQoL of both preschoolers and schoolchildren. Outcome standardization to measure OHRQoL impact was needed, such as mean score differences and cut-off points. To confirm these findings and to understand how TDIs’ impact changes with time, prospective cohort studies were recommended.
