Abstract:

Introduction:  Knowing root canal anatomy with all its exceptions is a key factor for the success of the endodontic treatment. Radix entomolaris is an anatomical variation of lower first molars which is very rarely found in patients from the European race.

Case report: A clinical case of a 28-years old patient with radix entomolaris is presented. Dental operating microscope and standard sector radiographs were used for the diagnostics and treatment of tooth 36. Root canals were instrumented with Ni-Ti rotary and reciprocating files. Clinical and radiographic healing was observed at the end of the first year after treatment.

Conclusion: Instrumentation of all existing root canals and their three dimensional sealing leads to predictable clinical result of the endodontic treatment. Good knowledge, usage of magnification and contemporary endodontic instruments aid the dentist in the treatment of complex clinical cases like radix entomolaris.
