Sometimes most of the Clinicians, especially Endodontists, encounter the variations in conventional or usual anatomy of the root canal systems. One of those unconventional and also strange complexities of canal morphology has been discussed in the present case. A 35-year-old female patient referred to the Department of Conservative Dentistry & Endodontics. On intraoral hard-tissue examination, deep occlusal caries was observed in relation to tooth number #34. After taking pre-operative IOPA radiograph it was noticed that both the premolars; #34 & #35 had two roots and also #35, which had a full crown restoration on it, was poorly obturated. So for this reason a primary root canal treatment was planned for #34 and Retreatment was planned for #35 (after removal of the full crown). Before starting any treatment a CBCT scan was done to see the three dimensional morphology of the concern teeth and that’s when a strange configuration of root as well as canal morphology was noticed. #34 had two roots; one mesial and one distal whereas #35 had two roots; one buccal root and one lingual root. Also tooth #36 showed multiple canals in distal root and after crown removal secondary caries was seen approaching the distal pulp horn with #36. So all three teeth went under Endodontic therapy under magnification using Dental operating microscope and were treated successfully.
