case_images: After determination of an estimated working length (WL) (Figure 2A), the canal space was filled with 5.25% NaOCl and was prepared with RaCe rotary instruments (FKG Dentaire, La-Chaux-de Fonds, Switzerland) up to 50/0.04 as the master apical file. CEM cement (BioniqueDent, Tehran, Iran) mixed according to user's instruction. Confirmation radiography was taken (Figure 2B) and after permanent crown restoration the patient was put on a scheduled follow-up. After six (Figure 2C) and 12 months (Figure 2D), the patient was symptom-free and the tooth was in function.
