The Association of Sleep, Awake, or Combined Sleep/Awake Bruxism and Temporomandibular Disorders Subtypes: A Cross-Sectional Population Study

Bruxism increased the risk for TMD subtype development, but it varied among the three bruxism types assessed (SB, AB, or combined SB/AB), and it was also modulated by sleep and psychosocial variables. SB and AB, separately and in combination, contribute to TMD subtype development and must be assessed in all studies.
