The prevalence of mandibular dysfunction. Part II: A multiphasic dysfunction profile

The frequency of occurrence of 20 signs and symptoms commonly associated with mandibular dysfunction was used to numerically rate the clinical severity of mandibular dysfunction. Some signs and symptoms had a clearly direct relationship whereas other signs demonstrated a diminished direct relationship, no relationship, or an inverse relationship in advanced dysfunction stages. Further study is needed to determine if there exists an exact relationship of some clinical signs to mandibular dysfunction.
