Figure 2. Comparison among baseline (B), occlusal splint (OS), and palatal control device (PCD) nights for the number of (a) bruxism episodes per hour, (b) episodes with tooth-grinding noise, and (c) bursts per hour. Median is shown for episodes/hr, since the data distribution was not normal; otherwise, means ± SEM are shown (nine subjects). * p 0.05 when compared with baseline value (details in Table).
