  		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 TableGo).

  		Figure 3. Individual data distribution for the number of bruxism episodes per hr for baseline (B), occlusal splint (OS), and palatal control device (PCD) nights. The median is circled. A decrease more important than night-to-night variability (25%) was observed for six and five patients, respectively, when occlusal splint and palatal control device nights were compared with the baseline night.
