  1. a The positive reaction was detected by electric pulp test (EPT), indicating that the pulp tissue was alive on enrollment. The tooth was left with camphorated phenol application in the cavity for 3 months before root canal treatment, and the pulp tissue became completely necrosis with a periapical lesion at that time
