Comparative Analysis of Dental Treatment Accuracy Using 2.5× Magnification Loupes Versus the Naked Eye: A Randomized Clinical Trial.

Background Magnification systems such as dental loupes have been increasingly incorporated into clinical dental practice to improve visualization, precision, and ergonomics. However, evidence evaluating their effectiveness during routine periodontal procedures performed by dental interns remains limited. The present study aimed to assess the effect of 2.5× dental magnification loupes on psychomotor skill acquisition and clinical treatment outcomes during ultrasonic scaling. Methodology This randomized clinical trial was conducted in the Department of Periodontology at Narayana Dental College and Hospital. A total of 20 patients requiring routine scaling were randomly assigned to either a magnification group (2.5× dental loupes) or a control group (conventional scaling without magnification), with 10 participants in each group. Ultrasonic scaling procedures were performed by dental interns. Clinical outcomes were evaluated using the Calculus Surface Index (CSI) component of the Oral Hygiene Index before and after scaling. Operator fatigue, treatment duration, and postural comfort were also assessed. Statistical analysis was performed using SPSS version 25, and a p-value <0.05 was considered statistically significant. Results Both groups demonstrated significant reductions in CSI scores following ultrasonic scaling, with mean reductions of 1.40 ± 0.52 in the control group and 1.90 ± 0.88 in the magnification group (p < 0.001). Baseline CSI scores were comparable between the groups (p = 0.913). However, the magnification group showed a greater reduction in CSI scores after treatment compared with the control group (p < 0.05). Postural comfort was significantly better among operators using magnification loupes (p = 0.012). Nevertheless, the magnification group demonstrated slightly higher fatigue scores and longer procedure duration. Conclusions The use of 2.5× dental magnification loupes during ultrasonic scaling may enhance calculus detection and improve clinical outcomes while promoting better operator ergonomics. Incorporating magnification-assisted techniques into dental training may contribute to improved psychomotor skills and clinical performance.
