Raghavendra SS, Napte BD, Desai NN, Hindlekar AN - J Conserv Dent (2015 Mar-Apr)

Bottom Line: Cone-beam computed tomography (CBCT) was employed to confirm the extension of the unusual anatomy.The clinician should expect to encounter unusual features when performing endodontic treatment.Use of diagnostic aids like CBCT, improved magnification with dental operating microscope, and the use of novel file systems like SAF ensure success.

ABSTRACT
The variability of root canal system morphology presents a continuous challenge to endodontic diagnosis and therapeutics. There have been reports of teeth with multiple roots and canals as also those with lesser number of root and root canals. Variations of root canal systems need not always be in the form of extra canals. Clinicians should be aware that there is a possibility of existence of fewer numbers of roots and root canals than normal, which presents varied canal anatomy and poses a challenge to the clinician's expertise. This case report deals with the management of an unusual case of C-shaped canal in mandibular molar with two buccally fused roots. Cone-beam computed tomography (CBCT) was employed to confirm the extension of the unusual anatomy. The Self Adjusting File (SAF) system was used to ensure complete cleaning of the canal system. One-year follow-up of the case showed good healing. The clinician should expect to encounter unusual features when performing endodontic treatment. Use of diagnostic aids like CBCT, improved magnification with dental operating microscope, and the use of novel file systems like SAF ensure success.

Mentions: Working length was determined using an apex locator (Root ZX II, Morita, Tokyo, Japan) and confirmed with radiographs. Cleaning and shaping was done using circumferential filing technique with ISO 2% taper files up to size 25 (Mani Inc, Tochigi-Ken, Japan) and further cleaning and shaping done with SAF (ReDent Nova, Israel) of 2mm diameter and 21mm length with pecking motion having 0.4mm amplitude and 5,000 oscillations per minute [Figure 1d]. Irrigation was performed using normal saline (Nirma Pvt limited, Gujarat, India), 5.25% sodium hypochlorite solution (Vishal Dental Products, Mumbai, India), and 17% ethylene diamine tetra acetic acid (EDTA; Prime Dental Products Pvt Ltd, Mumbai, India) as final flush. Final rinsing of the canal was performed using normal saline. The canal was dried with absorbent points (Dentsply Maillefer, Ballaigues, Switzerland) and obturation was performed using sectional method for the apical third [Figure 2a], followed by backfill with thermoplasticized gutta-percha using Obtura II (Obtura Spartan, Wendt Street Algonquin, IL, US) and AH Plus resin sealer (Maillefer Dentsply, Konstanz, Germany) [Figure 2b]. After completion of root canal treatment, the access cavity was restored using resin composite (3M ESPE Dental Products, St Paul, MN), followed by full coverage crown. One-year follow-up showed good healing [Figure 2c].
