5 Reproducibility of measurements of occlusal contact area obtained with an occlusal examination device

Abstract

We investigated reproducibility of measurements of occlusal contact area obtained with the T-Scan II system, which is an occlusal examination device. We measured the occlusal contact area at the five levels for 25, 50, 75, 90, and 100% maximum voluntary contraction (MVC). Five repetitions were made for each measurement over two days. Reproducibility of the occlusal contact area measurements was evaluated by intraclass correlation and by the standard error of measurement. The most stable measurements were obtained from the second and third clenching tests. We found reproducibility for within-day and between-days measurements of the occlusal contact area.
