Introduction: C-shaped canal configuration is mostly found in the mandibular second molar. The morphological characteristic of a C-shaped canal is the presence of a fin or web connecting the individual canal, making it difficult for cleaning, shaping, and obturation. The objective of this study was to find out the prevalence of C-shaped canal in mandibular second molar among cases of Cone Beam Computed Tomography in tertiary care hospitals. Methods: The descriptive cross-sectional study was conducted in the department of conservative dentistry and endodontics of tertiary care hospitals from 20th June 2020 to 20th December 2020 after receiving ethical approval from the Nepal Health Research Council on 19 June 2020. Cone-beam computed tomography images of 199 mandibular second molars with completely formed roots were used. Teeth with orthodontic braces, root resorption, root canal filling, and post were excluded from the study. The research was conducted taking a tooth as a unit. Convenience sampling was done. Statistical analysis was done by using Statistical Package for Social Sciences version 16. Point estimate at 95% Confidence Interval was calculated along with frequency and proportion for binary data. Results: The prevalence of C-shaped canal according to this study is 25 (12.6%) (7.99-17.21 at 95% Confidence Interval). Conclusions: The findings of the study conclude that C-shaped configuration is quite frequent in mandibular second molar among cases of Cone Beam Computed Tomography. A careful pre-operative radiographic evaluation may be helpful for diagnosing C-shaped configuration prior to root canal treatment.

The Mean

This study aimed to investigate the olfactory fossa according to the Keros classification using cone beam computed tomography. This cross-sectional study analysed cone beam computed tomography images selected from a database belonging to a radiology centre. The scans of 174 healthy patients were analysed by using the Xoran software. Gender, age, and side were correlated with the Keros classification. The mean age of the 174 patients was 45.3 years. The most prevalent Keros classification was type II (65.52%), followed by type III (20.69%) and type I (13.79%). No significant differences were found between Keros classification and the variables age, right side (pvalue = 0.4620), and left side (pvalue = 0.5709). There were also no significant differences between gender and the variables right side (pvalue = 0.1421) and left side (pvalue = 0.2136). Based on these results, we suggest that cone beam computed tomography can be recommended for analysis of the anterior skull base. Keros type II was the most prevalent type in our sample.

Introduction: The prevalence of Apical Root Resorption (ARR) after orthodontic treatment is high. It is associated with several factors, such as tooth group, type and duration of treatment, applied force and root morphology. Aim: To evaluate the apical root morphology of maxillary incisors in a Brazilian subpopulation using Cone Beam Computed Tomography (CBCT) images. Materials and Methods: In this retrospective and cross-sectional study, 400 maxillary incisors from 167 patients registered in the data base of Dental Radiology Clinics between January 2012 and April 2017 were analysed. The apical root configuration was verified by navigating 0.1 mm/0.1 mm, in the three planes, axial, coronal, and sagittal sections on CBCT images, from the root canal entrance to the apical foramen, as well as from the apical direction to the crown. The standard reference for apical root form corresponded to the long axis of the tooth. The root forms and their frequency were characterised according to the classification proposed by Levander and Malmgren (1988). The qualitative variables were analysed by the Chi-square test. The level of significance was p-value <0.05. Results: A total of 400 maxillary anterior teeth (central and lateral incisors; n=200 each) from 167 patients (101 women; mean age was 41.8±16.20 years) were analysed. The most common apical root form presented in the central incisors was the blunt root {99 (49.5%)}, followed by pipette-shaped root {69 (34.5%)}. The less frequent was the short root {13 (6.5%)} (p-value <0.001). In the lateral incisors, the highest frequency presented was lacerated root {111 (55.5%)}, followed by blunt root {47 (23.5%)}, and pipette- shaped root {37 (18.5%)} (p-value <0.001). Conclusion: Maxillary central incisors had a higher frequency of rhomboid (blunt) root morphology, while lateral incisors had a higher frequency of curved (lacerated) root form.
