Functional disturbances of the masticatory system in school children.

The centralization of treatment for functional masticatory disturbances by the Copenhagen Municipality Children's Dental Service has made possible the present survey of symptoms and results of treatment in a child population. Over a period of four years, a total of 366 children, aged six to sixteen (two thirds girls), were referred for treatment. Their symptoms differed from those reported by adult patients by a marked attrition of the mandibular incisors and concomitant sensitivity to thermal and mechanical stimulation. Other symptoms of functional disturbance, such as reduced mandibular mobility and muscle tenderness, were similar to those reported for adult subjects. Treatment conformed to conventional principles with widespread use of soft bite-splints (Figure 5). Both symptoms and signs were eliminated in about 60 percent of the patients, while 34 percent were essentially symptom-free at the conclusion of treatment. The survey showed that functional disturbances in the mandibular apparatus occur in children, and that many can be treated with good results. The symptomatology, however, resembles that of a wide range of other ailments, especially with respect to headache and facial pain, necessitating a careful differential diagnosis before functional corrective treatment is started.
