Why Keeps Hemorrhage?
A 48-year-old man has Class I malocclusion associated with multiple treatment, including implants at #3 and 4 and RCT at #8 and 14 in this office. A few years post composite restoration, the tooth #28 (linguoversion) develops acute pulpitis (Fig.1). Initial RCT reveals profuse hemorrhage from the seemingly single and large canal, even after debridement with 40/.04 rotary file. Ca(OH2) paste is placed and the patient is discharged. Four weeks later, the tooth is still sensitive. After local anesthesia, rubber dam is reloaded. Assuming that the incomplete treatment is due to insufficient length, attempt to extend the canal debridement fails. What should be done?
