DHT dental hard tissue, PDL periodontal ligament
^†This category includes teeth that were not reimplanted (n = 141) or could not be found (n = 13) after the accident
More teeth with PDL than with DHT or PDL + DHT injuries extracted: p < 0.001 (Pearson's Chi-squared test)
More deciduous than permanent teeth extracted (data not shown): p < 0.001 (Pearson's Chi-squared test)
