Abstract This study aims to observe the visual acuity of dental students in the function of the use of different levels of magnification of the Galilean loupes and the working distance adopted. Undergraduate students from the 2nd to 5th year will participate. The dependent variables will be the visual acuity and the distance between the operator's eyes/mouth of the mannequin. The independent variable will be the magnification system at 5 levels (naked eye, Galilean loupe simulator device without magnification, Galilean loupe with 2.5x, 3.0x, and 3.5x magnification). Visual acuity will be measured through a table of E-optotypes located in Class I cavities on upper molars. After checking the assumptions of normality and sphericity, the mixed Analysis of Variance will be performed (±=5%). (AU) | |
