“…CBCT overcomes these limitations by enabling us to visualize the third dimension and also eliminating super-impositions. It also aids in-depth understanding of the true morphology of root canals 26,27. CBCT in the present case guides the assessment of severity of the curvature of the root canals, the number of roots and root canals, and identifying separated or unseparated root canals.…”

Endodontic management of a mandibular second molar with radix entomolaris: a case report

2014

View full text Add to dashboard Cite

The presence of radix entomolaris (RE) in a mandibular first molar is a common occurrence in certain ethnic groups, but the presence of RE in a mandibular second molar is a rare occurrence. In the present case, RE was identified from preoperative radiographs and confirmed using cone-beam computed tomography (CBCT). The access cavity was modified to locate the RE. Cleaning and shaping were performed with nickel-titanium rotary instruments. Obturation was completed with gutta-percha cones using AH Plus (Dentsply Detrey GmbH) as sealer. From the CBCT axial images, the RE was determined to have a Type III curvature by the De Moor classification, Type B separate RE by the Carlsen and Alexandersen classification, and radiographically, a Type i image by the Wang classification. The presence of RE in the mandibular second molar makes it essential to anticipate and treat the distolingual root canal. This case report highlights the usefulness of CBCT for assessing RE in the mandibular second molar, which can help the clinician in making a confirmatory diagnosis and assessing the morphology of the root canal.

“…However, cases of maxillary lateral incisors with more than one canal and separate roots have been reported [4, 8, 27]. Variations in the number of canals are associated with dental anomalies or intrusive trauma to the primary teeth during the development of the permanent successors [27, 28].…”

“…Maxillary lateral incisors normally have a single root and single canal [3]. However, morphological variations for these teeth include the presence of two [4, 5], three [6, 7], four [8], and even five canals [9], usually associated with the occurrence of traumatic stimuli during tooth development process [10]. Other morphological variations such as dens invagination [9, 11], radicular groove [12], and fusion [13] have also been reported.…”

This paper reports a case of gemination in a maxillary lateral incisor with two root canals and crown-root dilaceration. A 16-year-old male patient was referred for endodontic treatment of the maxillary left lateral incisor and evaluation of esthetic and functional complaints in the anterior region. The patient reported trauma to the anterior primary teeth. There was no spontaneous pain, but the tooth responded positively to the vertical percussion test and negatively to the pulp vitality test. Clinical examination showed esthetic and functional alterations and normal periodontal tissues. CBCT imaging confirmed the suspicion of gemination and crown-root dilaceration and also revealed the presence of two root canals and periapical bone rarefaction. The root canals were instrumented with Reciproc R40 and 1% NaOCl irrigation and were filled by lateral condensation of gutta-percha and AH Plus sealer. The tooth was definitely restored with composite resin to recover esthetics. Continued follow-up over 6 months has shown absence of pain or clinical alterations as well as radiographic image suggestive of apical repair.

“…One such precaution was the staining of the tooth with methylene blue which, theoretically, would enhance the visibility by showing how far the PRG extend into dentin. 30 Recent evidence, however, suggests that staining may not necessarily enhance the detection of cracks because the dye cannot flow into craze lines unless there is a break on the surface. Once a crack propagates into a fissure or fracture, these can be stained with dyes.…”

“…Therefore, clinicians must be aware of the many variations in the root canal morphology of the tooth. 7 , 30 The success of the technique we implemented rests on proper infection elimination, adequate bone formation, disappearance of the underlying pocket, regaining of form and function, and patient's comfort.…”

Surgical management with intentional replantation on a tooth with palato-radicular groove

et al. 2015

View full text Add to dashboard Cite

A palato-radicular groove (PRG) is a developmental anomaly primarily found in the maxillary lateral incisors. It is a potential communication path between the root canal and the periodontium that decreases the survival prognosis of the affected tooth, therefore compromising the stability of the dental structure in the oral cavity. The aim of this case report is to present an original technique where a PRG was treated by means of intracanal disinfection, PRG sealing with glass ionomer, replantation with intentional horizontal 180 degree rotation of the tooth, and an aesthetic veneer placed to provide adequate tooth morphology. The clinical and biological benefits of this novel technique are presented and discussed.
