Introduction: Endodontics is specialty field, but the majority of endodontic treatment in Pokhara is provided by the general dental practitioners. The aim of this study was to assess the practice of endodontic treatment protocols among general dental practitioners in Pokhara, Nepal. Materials and Methods: A cross sectional questionnaire based study was conducted among all the general dental practitioners working in various government, private hospital and clinic of Pokhara. Information about the materials and techniques used in endodontic treatment was collected and descriptive statistical analysis was done. Results: Out of 89 respondents, only 82 completely filled the questionnaires which were included in the study. Most general dental practitioners (96.34%) regularly treat single rooted endodontic cases. Only 10.97% occasionally use rubber dam during endodontic treatment. Most general dental practitioners (96.34%) used radiographic technique for working length determination. Ninety two percent used stainless steel hand files and step back was the choice of technique by 90.24%. Sodium hypochlorite irrigation and calcium hydroxide intra canal medicaments were used by 93.9% and 98.78% of general dental practitioners respectively. 75.6% used zinc oxide eugenol as root canal sealer and 95.12% obturated root canals with lateral compaction technique. The common complication encountered was mid treatment pain. They seem to overuse antibiotics in cases requiring endodontic therapy. Only 52.43% used autoclave for sterilization of endodontic files. About 92.68% felt the need of further endodontic training and 74.39% preferred post graduate program. Conclusion: This study indicates that many general dental practitioners of Pokhara are not following well acknowledged endodontic quality guidelines; hence there is a need for further endodontic training.

Dental implant has been established as one of the most predictable and conservative approaches for the rehabilitation of missing teeth. With the evolution of newer material and advancement in digital technology, specially in computed tomography, implant planning software and guided implant surgery, the outcome and success in implant dentistry has become more predictable. Computer aided design (CAD) technique is being integrated into treatment planning, and computer-assisted manufacturing (CAM) is becoming more popular for rehabilitation procedures. This case report illustrate the diagnosis, planning and application of 3D guided technology in dental implant surgery

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.

Abstract-This paper discusses the design, development and evaluation of a data visualization prototype for a mobile application, for people with rheumatoid arthritis conditions. The visualizations concern ways of displaying graphically data for monitoring and evaluating the daily activities of rheumatoid arthritis sufferers. An initial visualization was developed and then a second was developed, aiming to be more usable and universally designed than the first version. An empirical experiment was used for evaluation and collection of quantitative data. Furthermore, semi-structured interviews were used for eliciting more qualitative data in terms of participant opinions. The overall results suggest that the second visualization was more usable and more universally designed than the first version. The paper concludes with some recommendations for future improvements.

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.
