  Introduction: Canals can be of different shapes in cross section including round canals, oval canals, long oval canals or ribbon shaped canals. Recesses of nonround canals may not be included in the round preparation created by rotary instruments and thus they remain unprepared. The aim of this study included determination of shape and taper of the apical root canal based on diameter at different levels. Methods: This was a cross sectional study which used convenient sampling technique to determine the sample size. Seventy extracted teeth were sectioned horizontally at one, two and three millimeter from the apex using the diamond disc which was observed under trinocular research microscope for the determination of diameter of root canal under 10x magnification. Results: The most common canal configuration was oval. The taper of the canals was 25% in mesial root and 20% in distal in bucco-lingual orientation and 14% in mesial root and 15% in distal in mesio-distal orientation. Conclusions: The most prevalent canal configuration in this study was non round, however, most of the rotary instruments tend to prepare root canals into round shape making their use questionable. The taper of the root canals was found to be higher in our study than what most of the shaping instruments have to offer. So it would be advisable to consider this fact while selecting instruments and preparing these non-round canals as far as the Nepalese subpopulation is considered.

ABSTRACT Aim To investigate the influence of cervical preflaring on apical file size determination using four different rotary instruments. Materials and methods Fifty root canals from extracted human maxillary premolars with complete root formation, straight roots were used for the study. Access opening was done and the working length established with 8 no K-file for each canal. Teeth were randomly divided into five groups of 10 canals. In Group 1- no preflaring was done and acted as control and in Groups 2, 3, 4 and 5 cervical and middle third preflaring of the root canals were done using Gates Glidden drills, Protaper instruments, Race instruments and Galaxy files respectively. After preflaring, the apical file size determination was done and the initial apical file (IAF) was fixed at the working length. Teeth were sectioned transversally 1 mm from the apex, with the binding file in position. The samples were imaged under stereomicroscope with 30× magnification. Root canal and file maximum diameters were recorded for each sample. The readings were subjected to analysis of variance test and Scheffe's multiple comparison test. Results Preflaring with Race instruments lead to most accurate determination of the IAF. It was followed by Protaper, Galaxy files and Gates Glidden drills. Conclusion Traditional method of apical size determination may lead to a substantial underestimation of actual canal size. Cervical preflaring increases the accuracy of apical size determination. Clinical significance Thus, cervical preflaring is recommended before selection of IAF as it increases the accuracy of apical size determination. How to cite this article Ashwini TS, Bhandari S.

Background: Permanent maxillary first molar normally has three root canals but it can have extra root canals for which several studies were done in many parts of the globe. However, this type of study to explore extra canal is lagging in the context of Nepal. Objectives: The objective was to determine the percentage of extra canal in permanent maxillary first molar in patients undergoing root canal treatment and to compare the same between male and female. Methods: The descriptive cross-sectional study was conducted in the department of conservative dentistry and endodontics of People’s Dental College and Hospital from 20th December 2019 to 20th December 2020 after receiving ethical approval from Nepal Health Research Council on 18th December 2019 (ERB protocol No 888/2019) . One hundred and eighty permanent maxillary first molar teeth without root canal calcification were enrolled. Convenient sampling was done. Access opening was done and all canal orifices were located and recorded. Data were analyzed using Statistical Package for the Social Sciences (SPSS) version 22.0 with frequency table. Chi-square test was used for inferential statistics. Results: Out of 180 teeth, extra canals were present in 44(24.4%) having more numbers in male than in females. Extra canal was present in the mesiobuccal root. Conclusion: Extra canal in the permanent maxillary first molar is present in Nepalese population with greater number in male than in female. Thus, exploration of the pulp chamber in search of an extra canal is necessary to prevent failure of root canal treatment.

Introduction: The objective of the study was to make the comparison of the root canal length of different types of teeth in black-Africans (Bantu) to that of Caucasians and Asians. Materials and Methods: Data from a prospective cross-sectional study of Bantu (Black Africans) subjects aged from 18 to 45 years who were admitted in Service of Conservative Dentistry of Kinshasa University, root canal length were compared with already published data from studies involving Caucasians and Asians. Results: This study includes 720 subjects; 480 (66%) were female and 240 (34%) were male. A total of 818 teeth were examined with 1539 root canals. The upper central incisor and the lower first molar predominated respectively in the maxilla and the mandible regions. There is a significant difference between the canal length of Bantu and Asians in the palatal canal of the upper second molar by 3.1 mm (p= 0.00). Eight different canals of Bantu were longer as compared to a single canal for Asians (p <0.05). This include the Vestibular (V) and palatine (P) canals of Bantu the first premolar (PM1 ), palatal of the second premolar (PM2 ), mesio-vestibular (MV), disto-vestibular (DV) and palatine (P) of the first molar (M1 ) mesio-vestibular and palatal of the second molar (M2 ). The lateral incisors (IL) (p= 0,01) and the canines (p= 0.12) of the Asians were longer than that of the Bantu. The Caucasians presented with longer canines than Bantu with a length difference of 1.7 mm (p= 0.11). Four Caucasians also presented with longer canals of the Mesio-Vestibular (MV) and mesiolingual (ML) of the two molars (M1 and M2 ) as compared to one for Bantu are the longest (p <0.05). Exceptionally, the distal canal (D) of the second molar (M2 ) of the Bantu was longer than that of the Caucasians, with a length difference of 1.5 mm. Conclusion: The root canal length of Bantu is between than those of the most Asian and shortest Caucasian.
