Background: A comprehensive understanding of the root form and canal anatomy is essential for successful endodontic treatment. This study aimed to evaluate the root canal anatomy of mandibular premolars in the Pakistani population using cone beam computed tomography (CBCT) and to classify the findings with the new classification proposed by Ahmed et al. METHODS: Ethical exemption was obtained from Aga Khan University Hospital, Karachi. A total of 707 CBCT scans from Karachi and Lahore were included, comprising 592 scans from a tertiary care hospital in Karachi and 115 scans from a radiology center in Lahore. The study focused on sound, fully formed mandibular first and second premolars, excluding those with significant caries, restorations, or prior root canal treatments. Scans from different equipment were used, and calibration was achieved between a specialist endodontist and two dental residents. Data was analyzed using the Statistical Package for the Social Sciences (SPSS) software, version 26. Descriptive statistics, Chi-square tests to determine association between the variables, and a significance level set at 5% (p <0.05) were utilized.
Results: A total of 2403 mandibular premolars were analyzed. The most common configuration was MPM (82.90%), with rare variations such as MPM (0.04%) and MPM (0.04%). Single-rooted premolars were predominant (98.87%), and no significant differences were observed when data was stratified by age or gender.
Conclusions: This is the first study in Pakistan involving multiple centers and using the classification system by Ahmed et al. to understand the anatomy of mandibular premolars. The findings indicate that while most premolars have a single root and canal, variations exist. These variations highlight the importance of understanding canal morphology for improving the success of endodontic treatment. Future studies should include a larger and more diverse dataset to fully represent the Pakistani population.

This micro-computed tomography (micro-CT) analysis in vitro study was designed to compare void volume in root canal fillings performed using the single-cone (SC) technique and the continuous wave condensation (CWC) technique with bioceramic (BC) sealer. Forty human-extracted, single-rooted mandibular premolars were cleaned, shaped, and divided into two groups (n = 20) based on the obturation technique. In the first group, obturation was performed using the CWC technique with TotalFill HiFlow BC sealer.

Background: Endodontic emergencies, often presented as acute pain or swelling, constitute a substantial challenge in dental practice. While effective management emphasizes prompt intervention, antibiotics are typically indicated only when systemic signs and symptoms are present. There is limited research exists on evaluating the knowledge and clinical approach of dental practitioners in managing endodontic emergencies from our region of the world.

This study evaluated the cytotoxicity and biocompatibility of a new strontium silicate-based root canal sealer (C-Root SP), in comparison with those of iRoot SP and AH plus. The sealer extract was diluted to the concentrations of 100%, 75%, 50%, and 25%. L929 cells were cultured for 24 h, and the absorbance value was determined.

Objectives: To compare the mechanical performance of partially replaced (repaired) intra-coronal restorations to totally replaced ones in root canal-treated teeth.
Methods: Thirty maxillary second premolars were selected according to strict criteria, mounted on moulds, and had mesio-occluso-distal (MOD) cavities prepared. Resin composite restorative material was used to perform the initial restoration, followed by aging procedures using thermo-mechanical cycling fatigue to replicate six months of intraoral aging.

Objectives: This study aimed to investigate cracked teeth and vertical root fracture observable on micro-CT images of extracted roots of mandibular incisors, after fiber post removal.
Materials And Methods: Thirty mandibular incisors were selected with any degree of slight incisal wear inspected with the aid of a stereomicroscope under 12x magnification, in order to have a group of young adult specimens according to the criteria of Hugoson et al. A sample of twelve mandibular incisors were selected, aged between 20 and 30 years old, with similar dentine volume and thickness.
