Radix mesiolingualis and radix distolingualis: a case report of a tooth with an unusual morphology

Gurudutt Nayak,Himanshu Aeran,Inderpreet Singh 대한치과보존학회 2016 Restorative Dentistry & Endodontics Vol.41 No.4

Variation in the root and canal morphology of the maxillary first molars is quite common. The most common configuration is 3 roots and 3 or 4 canals. Nonetheless, other possibilities still exist. The presence of an additional palatal root is rather uncommon and has been reported to have an incidence of 0.06 - 1.6% in varying populations studied. Whenever two palatal roots exist, one of them is the normal palatal root, the other is a supernumerary structure which can be located either mesiolingually (radix mesiolingualis) or distolingually (radix distolingualis). This case report describes successful endodontic treatment of a maxillary first molar with radix mesiolingualis and radix distolingualis. Identification of this variation was done through clinical examination along with the aid of multiangled radiographs, and an accurate assessment of this morphology was made with the help of a cone-beam computed tomography imaging. In addition to the literature review, this article also discusses the epidemiology, classifications, morphometric features, guidelines for diagnosis, and endodontic management of a maxillary first molar with extra-palatal root.

Biodentine-a novel dentinal substitute for single visit apexification

Gurudutt Nayak,Mohammad Faiz Hasan 대한치과보존학회 2014 Restorative Dentistry & Endodontics Vol.39 No.2

Use of an apical plug in management of cases with open apices has gained popularity in recent years. Biodentine, a new calcium silicate-based material has recently been introduced as a dentine substitute, whenever original dentine is damaged. This case report describes single visit apexification in a maxillary central incisor with necrotic pulp and open apex using Biodentine as an apical barrier, and a synthetic collagen material as an internal matrix. Following canal cleaning and shaping, calcium hydroxide was placed as an intracanal medicament for 1 mon. This was followed by placement of small piece of absorbable collagen membrane beyond the root apex to serve as matrix. An apical plug of Biodentine of 5 mm thickness was placed against the matrix using pre-fitted hand pluggers. The remainder of canal was back-filled with thermoplasticized gutta-percha and access cavity was restored with composite resin followed by all-ceramic crown. One year follow-up revealed restored aesthetics and function, absence of clinical signs and symptoms, resolution of periapical rarefaction, and a thin layer of calcific tissue formed apical to the Biodentine barrier. The positive clinical outcome in this case is encouraging for the use of Biodentine as an apical plug in single visit apexification procedures.

Asymmetry in mesial root number and morphology in mandibular second molars: a case report

Gurudutt Nayak,Shashit Shetty,Rhitu Shekhar 대한치과보존학회 2014 Restorative Dentistry & Endodontics Vol.39 No.1

Ambiguity in the root morphology of the mandibular second molars is quite common. The most common root canal configuration is 2 roots and 3 canals, nonetheless otherpossibilities may still exist. The presence of accessory roots is an interesting exampleof anatomic root variation. While the presence of radix entomolaris or radix paramolarisis regarded as a typical clinical finding of a three-rooted mandibular second permanentmolar, the occurrence of an additional mesial root is rather uncommon and representsa possibility of deviation from the regular norms. This case report describes successfulendodontic management of a three-rooted mandibular second molar presenting withan unusual accessory mesial root, which was identified with the aid of multiangledradiographs and cone-beam computed tomography imaging. This article also discussesthe prevalence, etiology, morphological variations, clinical approach to diagnosis, andsignificance of supernumerary roots in contemporary clinical dentistry.

Endodontic management of a maxillary first molar with three roots and seven root canals with the aid of cone-beam computed tomography

Gurudutt Nayak,Kamal Krishan Singh,Rhitu Shekhar 대한치과보존학회 2015 Restorative Dentistry & Endodontics Vol.40 No.3

Variation in root canal morphology, especially in maxillary first molar presents a constant challenge for a clinician in their detection and management. This case report describes the successful root canal treatment of a three rooted right maxillary first molar presenting with three canals each in the mesiobuccal and distobuccal roots and one canal in the palatal root. The clinical detection of this morphologic aberration was made using a dental operating microscope, and the canal configuration was established after correlating and computing the clinical, radiographic and cone-beam computed tomography (CBCT) scan findings. CBCT images confirmed the configuration of the canals in the mesiobuccal and distobuccal roots to be Al-Qudah and Awawdeh type (3-2) and type (3-2-1), respectively, whereas the palatal root had a Vertucci type I canal pattern. This report reaffirms the importance of careful examination of the floor of the pulp chamber with a dental operating microscope and the use of multiangled preoperative radiographs along with advanced diagnostic aids such as CBCT in identification and successful management of aberrant canal morphologies.
