The present case report highlights the need to identify variations in root canal anatomy as a prerequisite for effective nonsurgical root canal therapy planning. As clinicians, we need to develop our observational and clinical abilities as well as amend our understanding of the complexities of the canal anatomy. Reports describing the structure of teeth and pulp canals rarely report the presence of two pulp canals in two permanent upper 1st molars. In this case, it describes the nonsurgical root canal therapy of the upper right 1st permanent molar with two pulp canals, which was confirmed by a cone beam.

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 second molar. Cone-beam computed tomography (CBCT) was employed to conrm the extension of the unusual anatomy. 3-D Obturation done with the help of thermoplastic obturation unit.

Objective: The complex root canal anatomy is inherently colonised by microbial flora. Endodontic treatment success is always related to adequate disinfection of the root canal space, which ultimately affects the treatment outcome. A thorough understanding of the external and internal root canal anatomy by using adequately imaging modalities is essential before planning any treatment. The aim of this study was to investigate the number and morphology of the root canals of maxillary and mandibular premolars in Chennai population. Material and Methods: Full-size cone-beam computed tomographic images were randomly collected from 100 patients, resulting in a total of 200 first and 200 second maxillary premolars as well as 200 first and 200 second mandibular premolars. All the eight premolars were analysed in single patients, who underwent cone-beam computed tomography scanning during pre-operative assessment (before implant surgery, orthodontic treatment, diagnosis of dental-alveolar trauma or difficult root canal treatment). Total number of roots and root canals, frequency and correlations between men and women were recorded and statistically analysed by using chi-square tests. The root canal configurations were rated according to the Vertucci’s classification. Results: In the maxillary first premolar group (n = 200), 36.3% had 1 root, 56.7% had 2 roots and 7.0% had 3 roots, with most exhibiting a type IV canal configuration. In the maxillary second premolar group (n = 200), 60% had 1 root, 29.8% had 2 roots and 10.2% had 3 roots, with the majority of single-rooted second premolars exhibiting a type I canal configuration. In the mandibular first premolar group (n = 200), 80.5% had 1 root, 9.8% had 2 roots and 5% had 3 roots. In the mandibular second premolar group (n=200), 90.1% had 1 root, 6.4% had 2 roots and 3.5 % had 3 roots, with most exhibiting a type I canal configuration. No statistical correlation was found between number of roots, gender and tooth position. Conclusion: This cone-beam computed tomographic study confirmed previous anatomical and morphological investigations. Therefore, the possibility of additional root canals should be considered when treating premolars. Keywords: Cone-beam computed tomography; Mandibular; Maxillary; Premolar; Root canal; Morphology.

Patient Reported

The filling material should be restricted to the root canal, and not extend to the periradicular tissues. Overextension occurs when there is an overflow of gutta-percha and sealer, whereas overfilling refers to the overflow only of sealer beyond the apical foramen. Both may cause several negative clinical consequences. Nevertheless, an accurate diagnosis of where they occurred cannot always be performed by conventional radiographic examination, because of the two-dimensional aspect of the image. This paper describes a clinical case of labiomandibular paraesthesia after overfilling into the mandibular canal (MC), as diagnosed by cone-beam computed tomography (CBCT), later used to perform the treatment planning. A 34-year-old Caucasian female patient sought a private dental clinic complaining of pain in the right mandibular posterior region. After taking the anamnesis and performing clinical and radiographic exams, the patient was diagnosed with pulp necrosis in the second right mandibular molar, and underwent root canal treatment. The final radiography showed overextension or overfilling, probably into the MC. About 2 hours after the procedure, the patient reported paraesthesia of her lower right lip and chin. A CBCT confirmed a small overfilling into the MC. For this reason, vitamin B12 was prescribed as the first treatment option. After 7 days, the patient reported a significant decrease in paraesthesia, and was completely normal after 15 days. This case report shows that CBCT is an effective radiographic diagnostic tool that can be used as an alternative in clinical cases of labiomandibular paraesthesia caused by overextension or overfilling.   Keywords Endodontic treatment; Overfilling; Paraesthesia; Conebeam computed tomography.

Unusual Case Report

This case report showed an AOT in a 12-year-old female patient referred for orthodontic-surgical of both impacted right mandibular canine and lateral incisor. Cone beam computed tomography revealed a well-defined mixed hyperdense/hypodense lesion, involving the crown of the mandibular lateral incisor. The surgery consisted in surgical exposure of the mandibular right canine and lateral incisor, bonding of the lateral incisor for orthodontic traction and curettage of the mandibular lesion. Histopathological examination revealed several columnar epithelial cells with minimal stromal connective tissue, lobular pattern and rosettes and duct-like structures, confirming the diagnosis of AOT. After, the patient was referred for orthodontic traction of the impacted teeth. At 1 and 3-year postoperatively, follow-ups examinations showed extensive bone repair, resolution of the tooth-retention and absence of recurrence. Although AOT is an uncommon lesion in the mandible, it should be considered in the differential diagnosis of the mixed profile lesions in this region.

Inflammatory Changes

Cystic lesions of jaws are fairly common of which radicular cysts that form as a result of inflammatory changes associated with a non-vital pulp are most frequent. The removal of source of infection by either root canal treatment or extraction of the involved tooth leads to resolution of inflammatory cysts. However, infrequently, certain lesions may persist even after appropriate treatment which are termed as ‘residual cysts’. Although residual cysts are histopathologically indistinguishable from radicular cysts, certain changes may occur owing to removal of the aggravating stimulus which may lead to a varied histopathological picture. The present case report comprises of a residual cyst with a relatively unusual histopathological presentation.

Tooth Structure

Teeth with calcific metamorphosis pose a challenge to the endodontist in achieving proper access, identification, and debridement of the root canal. With the conventional technique, radiographs and bur orientation have dictated the access cavity preparation, which leads to the removal of more sound tooth structure and iatrogenic errors. To overcome these issues, the recent diagnostic imaging techniques such as cone beam computed tomography followed by three-dimensional fabrication of template have been proposed, which aid the clinician to accurately locate and negotiate the obliterated canal. The present case report describes the importance of conservative access cavity preparation with the use of the guided endodontic technique for the treatment of calcified canals in the maxillary central incisor.
