OBJECTIVES. The aim of this study was to investigate the advantages obtained from the use of optical magnification loupes in Class V composite restoration placement and finishing. MATERIALS AND METHODS. Twenty four extracted premolar teeth were used for the study. After obtaining a Black's Class V cavity, the samples were divided into two groups in view of subsequent restoration, namely Group A (test): 12 samples prepared through head-mounted loupes at 4X magnification and at working distance of 300 mm, and Group B (control): 12 samples restored without magnification system. RESULTS. Group A presented marginal gaps between 0 and 2.7 mm, versus values between 0 and 10.2 mm presented by Group B. The use of magnification influenced the percentage of irregularities in tooth-restoration surface and yielded an average error of 8.14 ± 6.01% in Group A versus 42.12 ± 9.83% in Group B. There was a significant (p < 0.0001) statistical difference between Group A and B. CONCLUSIONS. The use of magnification loops influences restoration in all its aspects and greatly reduces cavity marginal and surface irregularities. It follows that constant and sustained use of these instruments in clinical practice breeds excellent results.
