Occlusal relationship in patients with pain-dysfunction symptoms in the temporomandibular joints

A total of 135 patients (thirty-three males, 102 females) seeking treatment for pain and dysfunction of the TMJ were divided into five subgroups using the clinical dysfunction index of Helkimo. No relation could be found between the number of occluding molars and premolars and the severity of the symptoms nor the evolution of the complaints. A weak correlation was found between the outcome of the treatment with the occlusal splint and occlusal adjustment, and the above mentioned occlusal parameters (r = 0.47).
