[Changes in the masticatory system in myasthenia gravis]

Myastenia gravis causes by a hypofunction of the striated musculature a variable motor dyscoordination, which was examined in 106 patients. Hypofunction alone does not have any periodontal consequences, caries intensity however was obvious. Incoordination caused by hypofunction often is the cause for TMJ damage. The increase in mouth opening and of masticating force by Tensilon therapy is a characteristic and diagnostically useful test for myasthenia patients.
