Background: Dimension and location of pulp chamber are important during access cavity preparation. It allows clinician in instruments selection, orientation and depth of cutting during the process. Analysis of these has been done in preoperative intraoral periapical radiograph that gives two-dimensional image. The radiograph has been blamed now and then for the inaccurate results and iatrogenic damage occurred due to the inaccurate results. Cone-Beam Computed Tomography (CBCT) provides three-dimensional images and is taken as standard. Hence the aim of the study is to compare intra-oral periapical (IOPA) radiograph and CBCT to determine the landmarks for accurate results Methods: 50 intact two-rooted maxillary first premolars were collected and numbered. Periapical radiograph Images and CBCT images of these 50 teeth were taken and divided as; Group I: 50 IOPAR and Group II: 50 CBCT images. Landmarks marking and measurement was done using tracing paper and x-ray viewer for IOPA images and Planmeca Romexis software for CBCT images. Data were collected and analysed with descriptive and inferential statistics by using Statistical Package of Social Science (SPSS) software version 16. Results: The averages of group I are 7.44, 10.23mm 14.33mm, 4.1mm, 6.89mm and 2.79mm respectively. The averages of in group II are 6.95mm, 9.58mm, 14.03mm, 4.45mm, 7.07mm and 2.63mm respectively. There is statistically significant difference in measurement A and measurement B between group I and group II. Conclusions: This indicates that there are chances of overestimation of measurement A and B with IOPAR.
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.
In the present study, possibility of non-surgical endodontic re-treatment for correction of symptomatic endodontic failure with and without periradicular pathosis was evaluated both clinically and radiologically. The main objective of this study was also to assess, verify and establish the non-surgical re-treatment method as primary approach to resolve endodontic failures irrespective of sex. A total 69 cases of endodontic failure with or without periapical pathosis were studied of which 24 (34.78%) were male and 45 (65.21%) were female .The mostly affected teeth were Mandibular 1 st molars 19 in number (27.53%) followed by Maxillary central incisors 17 in number (24.63%). After one year follow up, the final outcome was success-47 (75.80%), doubtful-2 (3.22%) and failure-13 (20.96%)
Background: The success of root canal therapy depends on proper knowledge of root canal system, presence of extra canals, complete debridement and three-dimensional obturation of the entire root canal system. Previous studies have reported three to five canals in mandibular first molars. There might be chance of missing the canal that may lead to root canal failure, because of the variability in the number of root canals. The objective of this study was to determine the percentage of extra canal in the permanent mandibular first molar in patients undergoing root canal treatment. Methods: This cross-sectional study was conducted in the Department of Conservative Dentistry and Endodontics of Peoples Dental College and Hospital over a period of ten months from 6th September 2021 to 31st July 2022 after receiving ethical clearance from Institutional review Committee (IRC) Peoples dental college on 5th September 2021 (ref no1/ch no 5,2078/2079). About 350 mandibular first molar was selected by convenient sampling. After access preparation, all canal orifices were located and data were recorded. Data were analyzed using Statistical Package for the Social Sciences (SPSS) version 22.0 with frequency table. Results: Out of 350 patients, the percentage of three canals, four canals and five canals were respectively 273(78%), 76(21.7%) and 1(0.3%). Conclusions: The finding of this study supports the presence of extra canals in mandibular first molar. Thus, the clinicians require more diagnostic approaches, access modifications, and skills to locate, clean and shape the entire root canal system.
