Craniomandibular disorders and headaches.

Area of Science:

• Dentistry
• Neurology
• Pain Management

Background:

• Headache is a common complaint.
• Craniomandibular dysfunction (CMD) is associated with headache.
• The relationship between CMD and headache frequency requires further investigation.

Purpose of the Study:

• To compare headache incidence and frequency in patients with CMD versus a control group.
• To evaluate the efficacy of occlusal splint therapy in reducing headache frequency in CMD patients.

Main Methods:

• A study involving 300 patients, with 141 diagnosed with CMD and 159 in a comparison group.
• Headache incidence and frequency were assessed.
• A subset of 33 CMD patients with headaches received 4-week occlusal splint therapy.
• Headache frequency was recorded before and after treatment.

Main Results:

• Headache incidence was double in the CMD group compared to the control group (p < .001).
• Among those experiencing headaches, CMD patients reported significantly higher frequency (44%) than controls (p < .001).
• Occlusal splint therapy resulted in decreased headache frequency for 63.6% of patients and complete remission for 30.3%.
• The average weekly headache frequency decreased from 5.06 to 2.15 after therapy (p < .001).

Conclusions:

• CMD is significantly associated with a higher incidence and frequency of headaches.
• Occlusal splint therapy is an effective treatment for reducing headache frequency in patients with CMD.
• Further research into CMD-related headaches and treatment modalities is warranted.
