Abstract

Objective: To examine the availability and extent of magnification device use across dental specialties at Vietnamese institutions, including dental schools, specialty dental hospitals, and general hospitals with dental departments. Materials and Methods: A cross-sectional survey was conducted at 16 institutions comprising 11 educational units, 3 specialty dental hospitals, and 2 general hospitals with dental departments. An online questionnaire captured data on availability, duration of adoption, frequency and perceived necessity by specialty, and perceived advantages and drawbacks. Descriptive statistics were generated, and Chi-square tests were used to assess associations between sources of knowledge and level of understanding. Results: Endodontics reported the highest rates of use and perceived necessity for all three device types (≥70%). Most adoption duration was under 5 years. The most frequently cited advantages were improved visualization (about 25 to 30 percent), greater procedural precision (about 20 to 24 percent), and better working posture (about 20 to 24 percent). High cost (31 to 65 percent) was the most prominent barrier. There was a significant association between source of knowledge and level of understanding for loupes (p = 0.0012), while no significant differences were observed for operating microscopes or 3D microscopes. Conclusions: Magnification devices yield clear benefits in dental practice, particularly in endodontics, but their uptake is constrained by cost and bulk. Formal training plays a key role in improving understanding and adoption.
