Root Canal Treatment of a Hypertaurodont Mandibular Second Molar: A Case Report

Abstract

Taurodontism is a morphologic feature of generally multi-rooted teeth with large pulp chambers and shortened roots. A case of endodontic treatment in a 24-year-old male with the chief complaint of swelling and pain in the right mandibular region is described. Periapical lesion was present in the radiographic examination of hypertaurodont second mandibular molar.Four root canals were detected with an endodontic microscope. The canals were prepared and obturated with lateral condensation technique in the second appointment. The patient was asymptomatic in the 18-month follow-up.

Endodontic management of taurodontism with an open apex in mandibular first molar: A case report

“…Modified filling technique which is a combination of lateral condensation in the apical region with thermoplastic obturation system for obturating elongated pulp chamber has been recommended. [5,7,8] Moreover, in this case, we had another challenge that was an open apex of distal root. It was not possible to make an entire seal apically with lateral condensation technique in immature root canals.…”

“…MTA has many important characteristics including biocompatibility, marginal adaption, and less cytotoxicity than other materials which has been suggested to use as an apical plug at the end of immature roots with and open apices. [8,9] Hence, plug MTA was used to seal the apical region of distal root. This technique made it easier to have control during obturation of distal root by lateral condensation technique.…”

“…We used CBCT to evaluate our treatment after 9 months as it has been suggested in many current studies due to providing detailed information of the anatomy of roots. [4,7,8]…”

“…[5][6][7] High degree of variation of the size and shape of the pulp chamber, canal configuration, apically positioned canal orifices, and possible additional root canal systems have made the endodontic treatment of taurodont teeth so complicated. [8] In immature teeth, making an apical seal is the biggest problem endodontically. [9] Many studies have shown that mineral trioxide aggregate (MTA) due to some features including less leakage, high marginal adaptation, PH of 12.5, biocompatibility, and bioinductivity is the material of choice for use as a barrier to create an apical seal in immature teeth with an open apex.…”

Clinical implications of a diagnosis of taurodontism: A literature review

“…Because of this, the authors recommend the use of sodium hypochlorite to dissolve the remaining pulp that cannot be removed with instruments. 13,18 Kulkarni et al described a case of a patient who underwent root canal irrigation of tooth 37 with 2.5% sodium hypochlorite, 17% aqueous ethylene diamine tetra-acetic acid (EDTA) solution, 2% chlorhexidine gluconate, and saline. 4 According to Bharti et al, an irrigation with 5% sodium hypochlorite for 20 min-2 h can completely dissolve the pulp.…”
