As a follow up to an apicoectomy case, exploratory surgical re-entry to address the source of a sinus tract provides the opportunity to verify the healing of the cortical plate where apicoectomy was done two years earlier with the Bioceramic Root Repair Material and Putty.

This case verifies the biocompatibility and the ability of the previously described surgical technique to heal.

BC Sealer and Putty have since been shown to be very biocompatible through scientific research.
