case_images: CBCT was recommended to evaluate the root canal system; however, the patient preferred to complete the treatment without CBCT evaluation (Figure 1A). The root lengths were estimated and confirmed using an apex locator (Root ZX; Morita, Tokyo, Japan) and a radiograph (Figure 1B). Post-operative instructions were provided and the patient was referred to his general dentist for permanent restoration (Figure 1C). At the two year follow-up the treated tooth was functional and asymptomatic; radiographic evaluation showed normal periradicular tissues (Figure 1D).
