title: Associations among different orofacial dysfunctions in 6-8 year olds.
abstract: Associations among several orofacial dysfunctions such as articulatory speech disorders, craniomandibular disorders (CMD) and problems in coordinating the orofacial muscles were examined in two groups of Finnish first-graders, i.e. children with and without speech disorders. In the whole sample of 287 subjects the mean age was 7.5 yr. A speech therapist diagnosed articulatory speech disorders and a phoniatrician examined the morphology and function of the articulators. Signs and symptoms of CMD, capacity for mandibular movement, and prevalence of occlusal interferences were examined by a dentist. Deviations in motor skills, but not in morphology of the articulators, were associated with speech disorders. The findings also suggested that capacity for mandibular movement, deviation of the jaw during maximal mouth opening and occlusal interferences were related to certain speech disorders among these 6-8 yr olds. Different orofacial dysfunctions appear to be associated with each other during growth.
