Microscope in Endododontics. Case Study Number 513236.

We have been confronted to this three rooted mandibular first molar (Radix Molar or Radix Entomolaris), a rare anatomical variation of teeth, where a third supernumerary root is located distolingually in mandibular molars. Root canal system calcifications and a small radius root canal curvature with an “S” form made this endodontic procedure a complex one.

The prognosis of dilacerated teeth that require endodontic treatment … is difficult to predict before treatment, and in many cases, the prognosis will not become evident until the practitioner has undertaken initial endodontic treatment to determine wether the canal can be negotiated completely and then adequately disinfected and filled.

In that specific case, endodontist  operative microscope was most helpful when striving to find the fourth canal entry in distal root, allowing for us not to omit the fourth deeply embedded root canal. This microendodontic case study enlightens how dental operative microscope may assist the practicing dentist into a more secure root canal procedure for his patient. Root canal preparation and filling as been completed with stainless steel K endodontic files in conjunction with the Pro Taper system from Dentsply. Root canal obturation as been completed with gutta percha and Pulp canal Sealer from Kerr using the Schilder-Yu condensation technique.
