*
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.
