The prevalence of symptoms of craniomandibular disorders (CMD) was studied by using a questionnaire in a random sample of 76-, 81-, and 86-year-old subjects living in Helsinki, Finland. Symptoms were reported with lower prevalence with increasing age. Of the total group of 364, 34% reported awareness of one or more symptoms of CMD, but only 2% found their symptoms extremely severe. Thirty per cent reported pains in the head and neck region, and 4% had headache daily.
