In this systematic review, we compare the quality and accuracy of computer-aided design (CAD)/computeraided manufacturing (CAM) techniques currently employed in dentistry with those of traditional materials. Published literature on the study topic was searched in the online MEDLINE, PsycINFO, PubMed, and Cochrane library databases and the database of Indian Council of Medical Research. For this systematic review, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework was applied for the assessment of studies fit for investigation. Of the total 103 papers searched, 54 underwent indepth evaluation. Using criteria for what to include and what to leave out, we chose research that was relevant to our review and narrowed it down to 14 papers that met the review's guidelines. According to our findings and the analysis of the chosen articles, the prospects and current advances of CAD/CAM technology are fascinating and are revolutionizing the field of dentistry. Even though researchers are excited, it is important to make sure that different materials have been tested and looked at well enough before making firm claims and choices to replace materials that have been made in the past. Based on previous research, it has been determined that the CAD/CAM methodology used in the dental field is the most popular method at the moment since it is quick, simple, and efficient. Since there are different kinds of CAD/CAM systems, it is very important to choose the right one and come up with a good plan for treating a patient.
Background: When taking into account several factors, including the kind and intensity of the light source, the season, the angle of incidence, the patient's attire, age, gender, and the time of day and year, color is one of the most crucial variables of aesthetic dentistry. The most challenging part of prosthetic dentistry is choosing a replacement tooth's color so that it blends in with the surrounding teeth and covers gingival tissue. As a result of the fact that having an understanding of the concept of color is extremely important in order to achieve good aesthetics, and the distribution of color is highly important to achieve shade matching.Aim of the study: The goal of this study was to evaluate dental professionals' self-reported knowledge, attitudes, and practices regarding anterior tooth shade matching in Saudi Arabia.Methodology: This research study was conducted in Saudi Arabia from February to April 2022. Two hundred fifteen registered dental practitioners participated in the cross-sectional, closed-ended questionnaire-based survey. Dental health professionals working in dental colleges, dental clinics, or other dentally significant institutions like hospitals (both government and private) and their respective private practices in various capacities as professors, teachers, or post-graduate students answered the research questionnaire. Dentists who were not involved actively in shade selection or declined to participate in contact through the mail were excluded. Chi-square and Fisher's exact tests were used for the comparison of categorical data, and a p-value of 0.05 at 95% CI was statistically significant.Results: Among the questions that were asked, the majority of them said age, sex, gender play, and appointment timing, along with patient opinion play a very important role in shade selection. Moreover, among the patients, 34% noted the manual method of shade selection, and 45.6% of them chose a combination of manual and mechanical methods. When they were asked about the commonest reason they came across for doing a shade selection of anterior teeth, around 52.60% said aesthetics, while 20.90% said fracture of anterior teeth. While 19.1% of people used rubber dam isolation, 34.0% of them preferred the use of cotton rolls and absorbing points, and only 16.7% of them often used Teflon tape. The majority of them had difficulty with shade selection due to the light source, as viewing shades in poor quality light influences how color is perceived; thus, the quality of light is the most influential factor in shade-taking practices. Around 44.7% of them preferred to do shade selection under natural daylight.Conclusion: Based on the results obtained from the current study, the authors would like to conclude that more attention should be focused on improving the knowledge of color science and its application in aesthetic dentistry, as the color and appearance of teeth are complex phenomena with many factors. Hence, for a good aesthetic outcome to be achieved, the dentist should consider all possible entiti...
Background : This knowledge, attitude, and practices (KAP) survey will provide baseline data and identify gaps that may facilitate understanding and further action to plan, implement, and evaluate practice toward 3D-printing technology among dental practitioners in Saudi Arabia. Aims and objectives: The present study aims to assess dental practitioners' self-reported knowledge, attitude, and practice of 3D printing in Saudi Arabia. Methodology: A cross-sectional, closed-ended questionnaire of registered dental practitioners in Saudi Arabia was conducted. A sample size of 156 was considered for analysis. After obtaining approval from the Institutional Review Board, Riyadh Elm University, the research was conducted during the month of April 2022 amongst 154 registered dental practitioners. The research was distributed among dental health specialists either working in dental colleges, dental clinics, or both in government as well as private settings. Dentists who were not actively involved in 3D printing were excluded. SPSS software, version 25.0, (IBM Corp., Armonk, NY) was used to analyze the data. Results and conclusion: Of all dentists included in the study, 98% were found to be aware that 3D printing in dentistry is used in Saudi Arabia and 2 % were not aware of its usage in Saudi Arabia. In total, 78.60% of the dentists felt that 3D-printed implant guides made the placement of implants the most accurate and least complicated procedure, and 21.40% of the dentists felt it was the least accurate and most complicated procedure.
Digital dentistry has gained significant attention in recent years due to its potential to improve the accuracy of implant placement and prosthesis fabrication. However, the literature on its effectiveness remains controversial, and a systematic review and meta-analysis are necessary to evaluate the available evidence. A comprehensive search was conducted across multiple online databases using MeSH keywords and Boolean operators. Data extraction was performed, and a bias assessment was conducted based on modified CONSORT guidelines. The pooled odds ratios (OR) and risk ratios (RR) and corresponding 95% confidence intervals (CI) were then calculated. Five studies met the inclusion criteria. The overall analysis showed no statistically significant difference in the accuracy of implant placement and prosthesis fabrication between digital and conventional techniques (OR: 0.95, 95% CI: 0.73 to 1.23 and RR: 0.95, 95% CI: 0.73 to 1.23). Subgroup analysis based on individual studies did not demonstrate consistent results. This review suggests that digital techniques do not significantly impact the accuracy of implant placement and prosthesis fabrication compared to conventional techniques in an in vitro setting. However, the overall evidence is limited by the small number of studies and the heterogeneity observed. Future well-designed studies, including randomized controlled trials and clinical studies, are needed to provide more robust evidence on the effectiveness of digital dentistry in clinical practice.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
