The success of a dental restoration is influenced by the marginal adaptation. This study describes a calibration exercise conducted by 20 dental faculty members to evaluate ceramic onlays on maxillary right second molars. The participants aimed to identify the largest gap between the restoration and gingival cavosurface margin of nine IPS e.max (Ivoclar Vivadent) milled onlay restorations fabricated using computer-aided design/computer-assisted manufacture technology. This blinded exercise consisted of, and aimed to compare, both tactile and radiographic evaluations. Of the 180 tactile evaluations, 48.33% rated the marginal gaps as clinically unacceptable using United States Public Health Service criteria (> 100 μm). When radiographs were used, 88.33% of the evaluations revealed unacceptable marginal gaps. Thus, this pilot study showed a discrepancy between tactile and radiographic evaluations. The results suggest that clinicians are better able to interpret marginal gaps and their clinical acceptability when using digital radiographs than when using a no. 17 explorer and tactile evaluation.
