Article Abstract
Objectives: To evaluate the technical quality of root canal obturations performed by undergraduate students.
Methods: The records of 347 patients who underwent endodontic treatment by undergraduate students of Qassim University between 2018 and 2020 were assessed using standardised criteria based on obturation length, density and taper. All teeth that received primary endodontic treatment and had post-obturation periapical radiographs depicting the entire radicular length and the 2-3-mm periradicular area were included in the study.
Results: A total of 653 canals of 397 teeth were evaluated. The maxillary central incisor was the most commonly assessed tooth (15.1%). Overall, 80.2% of the evaluated canals were deemed acceptable based on all three assessment criteria. Maxillary teeth had significantly better obturation quality than the mandibular teeth. The mesio-lingual canal had the lowest quality in all three criteria.
Conclusions: The technical quality of root canal obturations performed by undergraduate students in Qassim University was acceptable in the majority of the evaluated cases. Among the evaluated parameters of obturation quality, length control was the most frequently observed deficiency. Additional measures are therefore required to improve the quality of the obturation length.

Dysregulation of renin-angiotensin-aldosterone system (RAAS) often leads to hypertension and severe cardiorenal complications. Although RAAS-targeted therapies have proven effective, it remains yet optimal in reducing cardiovascular events. The aim of this study was to evaluate the efficacy and safety of angiotensin receptor neprilysin inhibitor (ARNI) compared to control in patients with hypertension.

Background: Programmed cell death ligand 1 (PD-L1) expression on immune cells is correlated with the efficacy of immune checkpoint inhibitor (ICI) therapy in various types of cancer. Platelets are important components of the tumour microenvironment (TME) and are widely involved in the development of many types of cancer including colorectal cancer (CRC). However, the role of PD-L1 positive platelets in ICI therapy for CRC remains unknown.
