RCT #30 through a Zirconia Crown. There was an extra DL root with considerable apical curvature.
RCT #15 through a temporary bridge. Note the conservative access made to preserve as much remaining tooth structure as possible.
RCT #8 through a Porcelain Crown and restored following treatment. This case was calcified into the coronal root third. A conservative access was made with the help of cone beam imaging to preserve peri-cervical dentin, keep the current crown, and give the overall case a great long term prognosis.
Retreatment #3. Access was made through the existing crown, a palatal post was removed, additional MB anatomy was found, and all canals were retreated.
RCT #30. Note the deep split in distal anatomy. Usually we have a good idea additional anatomy is present by looking at traditional periapical radiographs. Sometimes additional 3D imaging is necessary.
RCT #’s 14 & 15. In these cases we removed all decay and made conservative accesses into the pulp chambers. The DB canal of #15 was 25mm long and had a 90 degree curvature. These are fairly predictable canals to treat once we have a good glide path and crown down with rotaries.
RCT #31. Note the additional anatomy found with sealer and down packing. We typically see this in our cases after thorough irrigation.
RCT #14. An extremely conservative access was made though a brand new crown and restored following treatment. When new crowns are present, we do everything we can to preserve the existing crown and remaining tooth structure.
RCT #3. I included this case to show management of considerable canal curvature.
Retreatment #19: This is an example of complex restorative treatment that can be completed at our office following root canal therapy. A deep alloy buildup was placed and rough preparation was done following treatment. This case has a questionable long term prognosis. However, the patient has a history of failed implants and was intent on keeping #19 as long as possible.
RCT #18. This is very straightforward. A one canaled molar that we see every so often. Note the apical anatomy sealed by using advanced irrigation techniques, and proper down packing during obturation.
