Background: The aim of the study to investigate the accessibility and frequency of use of magnification systems in endodontics and to evaluate the economic and logistical factors., Methods: A survey comprising of 34 questions, created in Survey Monkey, was sent to 874 clinicians. The survey consisted of three main sections: demographic information, the use of magnification systems, and financial factors. Descriptive analysis and chi-square tests were performed., Results: Of the participants, 42.3% were endodontists, and 57.7% were postgraduate students in endodontics. Nearly 26.1%, 32.7%, and 41.1% reported using a dental operating microscope (DOM), a loupe, and no magnification system, respectively. When asked how long it would take to recoup the cost of the DOM, considering additional charges or patient preferences, the most common response (40%) was 1-2 years., Conclusion: Although the use of magnification systems has become quite widespread today, it is important to increase their use further. The procurement and use of DOMs have not created a long-term financial burden for clinicians., Competing Interests: Declarations. Ethics approval and consent to participate: Ethical approval for the study was obtained from Kütahya Health Sciences University Non-interventional Clinical Studies Ethics Committee (Approval number: 2024/01–04).

Background: Growth factors embedded in the extracellular matrix of the dentin play an important role in the migration, proliferation, and differentiation of dental pulp stem cells in regenerative endodontics. In regenerative endodontic treatments, the type of irrigation solution used is crucial for the release of growth factors (GFs) from the dentin matrix. This study evaluated the effectiveness of different irrigant activation techniques (IAT) using two different chelating agents, 17% ethylenediaminetetraacetic acid (EDTA) and 9% etidronic acid (HEDP), in terms of their GF release., Methods: Seventy-two mandibular premolar teeth were prepared to simulate an open apex. The root fragments were irrigated with 20 ml of 1.5% sodium hypochlorite and 20 ml of saline solution. Eight root fragments were randomly separated for the control group, and the remaining 64 fragments were randomly separated into eight groups based on two different chelating agents (17% EDTA and 9% HEDP) and four different IAT ((conventional needle irrigation (CNI), passive ultrasonic irrigation (PUI), sonic activation with EDDY, and XP-endo Finisher (XPF)). TGF-β1, VEGF-A, BMP-7 and IGF-1 release levels were determined using an ELISA, and statistical analysis was performed using the Kolmogorov-Smirnov test, ANOVA, and the Tukey test (p < .05)., Results: Compared to the control group, the experimental groups showed significantly higher GF release when using EDTA or HEDP. Among the activation groups, the EDDY group triggered the highest GF release, and the CNI group triggered the lowest., Conclusions: IAT with EDTA and HEDP can increase GF release, with EDDY being the most effective IAT method. Using chelating agents with IAT may be beneficial in regenerative endodontic treatments., (© 2024. The Author(s).)

Objectives: This study aimed to evaluate the content, quality and demographics of YouTube videos about rubber dam as an information source for clinicians and dental students., Materials and Methods: "Rubber dam," "rubber dam application," "dental isolation," "rubber dam isolation," and "dental dam" were determined as keywords for the detection of YouTube videos related to rubber dam. Seventy 3 videos were evaluated and a total of 34 videos met the inclusion criteria. All selected videos were evaluated according to 8 parameters. The videos were scored 1 if the videos contained information about the selected parameter, but if the videos did not contain enough information, they were scored 0. The data were statistically analyzed with the analysis of variance and post hoc Tukey test ( p < 0.05)., Results: We found that 41% of the videos have poor, 47% have moderate, and 12% have good information. There is a statistically significant difference in time between poor and good information content ( p < 0.05). There is a statistically significant difference between the poor and good information in the video information and quality index 1., Conclusions: Rubber dam-related videos available on YouTube are generally moderately informed and insufficient. YouTube is currently not sufficient as a source of information for patients and clinicians at the moment. The YouTube platform should be developed and enriched with quality information on current and dental issues., Competing Interests: Conflict of Interest: No potential conflict of interest relevant to this article was reported., (Copyright © 2024.
