*

NC=no change; DB=dentin bridge; PCO=pulp canal obliteration; IRR-NP=internal root resorption-nonperforated form; PDL=periodontal ligament widening; ERR=external resorption; IRR-P=internal root resorption–perforated form; PRL=periradicular lesion.

IRR-NP=5/28 (18%).

IRR-NP=4/39 (10%).

§

Radiographic failures included: IRR, ERR, IRR-P, and PRL; PDL occurring alone was not considered a failure.

Statistically significant at the P≤.05 level.
