Background: Contemporary undergraduate dental education aims to equip the dental students with clinical competence, empathy, and professionalism to enable them to deliver safe and effective dental care to the communities. The purpose of this study was to assess the self-reported preparedness of final year dental students and interns at three Saudi dental institutions, using the pre-validated Dental Undergraduates Preparedness Assessment Scale (DU-PAS)., Methods: A cross-sectional study design was employed to assess the self-reported preparedness of the participants using the DU-PAS. Following ethics approval, a probability sampling technique was used to recruit undergraduate dental students and interns from three dental institutions in Saudi Arabia. The data was collected online on Google Forms and all participants provided their consent to participate in the study prior to providing their responses to DU-PAS., Results: Responses were received from 397 participants including 171 males and 226 females yielding a response rate of 60.3%. The total mean score of the participants was 81.85 ± 13.11. Although higher scores were reported in males, the interaction between gender and DU-PAS scores were not significant. Interaction between DU-PAS scores and stage of education showed significant effect of the stage of education with interns reporting higher overall scores. The participants reported that they were able to perform most clinical procedures independently. However, low confidence was reported in performing multi-rooted endodontics, fabrication of removable dentures and orthodontic assessment. The participants also expressed their confidence in a wide range of behavioural attributes related to communication, teamworking and professionalism. However, lack of experience was noted in referral for oral cancer, interpreting research, and evaluation of new dental products using an evidence-based approach., Conclusion: The study provides useful insights into the self-reported preparedness of undergraduate dental students and interns in three dental institutions. While the overall preparedness of the participants was comparable to their international peers, the findings underscore the need for further enhancements to the teaching and training of undergraduate students particularly in multirooted endodontics, removable prosthodontics and orthodontics., (© 2024.

Light-activated disinfection (LAD) has emerged as a novel approach toward antimicrobial disinfection within the root canal. This approach is based on the concept that porphyrins and photosensitizers (PSs) can be activated by light to produce cytotoxic elements that induce the desired therapeutic effect. Unlike antibiotics, LAD can act on multiple targets within a bacterial cell, including membrane lipids, genomic DNA and various proteins, including enzymes, thus reducing the ability of the organism to acquire resistance.The aim of this review was to develop an understanding of the potential use of LAD in endodontics and to suggest strategies to maximize the antibacterial effects of LAD.The electronic searches of the PubMed/MEDLINE, Web of Science, Scopus, and Cochrane databases were complemented by a manual hand search. A total of 303 studies were evaluated for essential parameters, which included the origin, types/variations, methodology, and application of LAD in in vitro and in vivo studies.It can be concluded that LAD is effective against the vast majority of bacterial pathogens, including antibioticresistant Gram-negative and Gram-positive bacteria, along with several yeasts, viruses and protozoan species. The literature tends to suggest that LAD can be used either as a substitute or an adjunct to the conventional antimicrobial treatment regimens that are implemented to battle polymicrobial biofilms.
