Natural Root Endo Tooth 45 with Access Cavity

Tooth 45 Version 2 has three flutings that suggest the possibility of extra canals, but there are none. The medium-sized pulp chamber is easily found during access; however, the canal is small and has multi-planer curvature that offers a slight challenge to negotiation, requiring file bending and effective direction of the bent file tip to reach this terminus, with an access cavity.
