Aim and Objective: This study aims to evaluate the knowledge and attitude of practicing dental health professionals (DHPs) (dentist and dental auxiliaries) toward Middle East Respiratory Syndrome coronavirus (MERS-CoV) in Saudi Arabia. Materials and Methods: A cross-sectional descriptive study was undertaken among practicing DHPs in Saudi Arabia. A total of 202 DHPs participated in this study. Knowledge and attitude were assessed using self-administered and pretested questionnaire. The questionnaire was administered online through Survey Monkey® program by sending link to the registered E-mail. Descriptive statistics were performed on demographic data. Mean knowledge and mean attitude scores of DHPs were calculated. Mann-Whitney U-test and Kruskal-Wallis tests were used to disclose the differences between study variables. Chi-square tests and Spearman's correlation tests were applied to find the associations between the variables. Results: The study participants showed mean knowledge score of 12.26 +- 2.27 (based on 17 knowledge questions) and attitude score of 8.63 +- 1.68 (based on 10 attitude questions). The spearman's test showed the positive correlation between knowledge and attitude of DHPs about MERS (r = 0.093, P = 0.188). Knowledge gaps were reflected in questions related to the duration of infectivity (47.5%), treatment of MERS (39.6%), reservoir of MERS-CoV (38.1%), availability of vaccination against MERS-CoV (25.2%), the likelihood of infection (24.3%), and the type of MERS-CoV (23.3%). DHPs showed a positive attitude toward adherence to universal precautions given by CDC and WHO (0.94 +- 0.25), active participation infection control program (0.94 +- 0.24), and use of gowns, gloves, mask, and goggles while dealing with MERS-CoV patients (0.97 +- 0.17). Male DHPs showed significantly higher knowledge and positive attitude toward MERS-CoV infection compared to females. Conclusion: DHPs participated in this study showed good knowledge and positive attitude toward MERS. However, still few lacunae in the knowledge and attitudes toward MERS-CoV were found requiring extensive educational programs.

Digital imaging has surely resurfaced dentistry as an extremely modern practice, thereby increasing diagnostic and treatment-planning capabilities to a whole new level, thus enhancing patient care and clinical efficiency. This transition from film-based radiography to digital technologies, including digital radiography, intraoral cameras, cone-beam computed tomography, and intraoral scanners, has significantly improved diagnostic accuracy, reduced radiation dosage, and smoothed the workflow. Cone beam computed tomography has given a fillip to detailed 3D imaging in complex cases of implantology and orthodontics; intraoral scanners and CAD/CAM systems have come to enhance restorative accuracy. Even with some drawbacks persisting, this integration of artificial intelligence into dental medicine, or rather being at the threshold of new technologies such as augmented reality, augurs well for further development. This review has outlined the paradigm shift of digital imaging in various dental specialties and looks forward to future opportunities for maximizing its application in a clinical setup.

The accuracy of definitive impressions has a significant impact on the quality of the final prosthesis. Elastic impression materials are commonly used in the traditional approach to replicate anatomical structures while indirectly fabricating prostheses. Digital impression has gained increasing popularity due to its various advantages, including three-dimensional previsualization, cost-effectiveness, and reduced time consumption. The objective of this study is to evaluate existing studies to provide an overview of the comparative advantages of digital impression techniques over conventional techniques. The review will focus on evaluating the accuracy, patient acceptability, operator preference, and time effectiveness of digital impression techniques in comparison to conventional techniques. The Population, Intervention, Comparison, and Outcome framework served as the basis for this study's search strategy. We conducted a comprehensive literature review by electronically searching articles published between 2000 and 2023 in PubMed, Medline, Cochrane, and the Web of Science. Furthermore, additional manual searches were conducted. The study examined the differences between optical impressions and traditional impressions in terms of accuracy, patient outcomes, and operator outcomes. It included both clinical and preclinical studies as well as randomized controlled trials. In conclusion, this review provides a short summary indicating that digital impressions exhibit comparable accuracy to conventional impressions without any statistically significant difference. This conclusion is based on an evaluation of accuracy, patient preference, and operator preference.
