BROKEN INSTRUMENTS…OR MODIFIED ROOT FILLING?
Here we present a relatively interesting case, #14, with a recurrent infection associated with the MB root. Other than pain associated with this tooth, medical history remains unremarkable. We were able to remove the “root filling” which appears to be endodontic instruments that may have also been used in initial instrumentation. In any case, we were able to remove the all three instruments and locate a previously untreated MB2 canal. This would prove to be significant as this it the only canal in the MB root that was able to be instrumented to full root length. Pre-operative CBCT would suggest that both MB root canals may share a common exit. This is also the rationale for using bioceramic sealer in obturation as it is hypdrophilic and expansive. Stay tuned for the follow-up!
