Pulpitis	Chronic ulcer	Chronic ulcer^a	Acute suppurative	Chronic ulcer	Chronic ulcer
Unnecessary tooth	Upper right 3rd molar	Upper right 3rd molar	Upper right 3rd molar	Upper left 3rd molar	Upper left 3rd molar
Time between pulpectomy and transplantation	11 weeks	3 weeks	6 weeks	3 weeks	12 weeks

^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
