The dependent variable was (1) individuals having occasional or no TMD pain, opening difficulties CAL-101 nmr or clicking (n65?=?5596; n75?=?3285) and (2) individuals with great or rather great problems regarding TMD pain, opening difficulties or clicking (n65?=?246; n75?=?104). No significant difference between the response and non-response groups was found concerning either gender or county of origin when the two age groups were taken together. However, there were significant gender differences when the age groups were analysed separately. In the 75-year-old group there were 46.8% men and 53.2% women in the response group, while the corresponding numbers for non-response were 41.3% and 58.7%. In the 65-year-old group, there were 49.3% men and 50.7% women in the response group; the corresponding numbers for non-response were 53.3% and 46.7%. Thus there was a difference between the response and non-response groups according to gender, controlled for age group, but no difference for county of origin. TMD symptoms.? Most responders were not aware of any TMD-related problems. Among those reporting any such symptom less than 4% of the subjects considered any of them to be rather great or severe. However, there was evident difference between the sexes: 5.4% of the 65-year-old women and 3.8% of the 75-year-old women considered their symptoms severe or rather severe; the corresponding prevalences for the men were 2.9 and 2.3%, respectively. The prevalence of the three reported troublesome TMD symptoms was higher in women than in men in both age cohorts (Table?1). The differences were significant for all three symptoms at age 65 (p?<?0.001) but only for TMJ pain (p?<?0.01) and opening (p?<?0.001) at age 75. The 75- compared to the 65-year-old women had a significantly lower prevalence of TMJ pain (p?<?0.001) and TMJ sounds (p?<?0.01), but not of mouth opening (p?=?0.1). The older men reported fewer symptoms than the younger ones, but the differences were not statistically significant. The prevalence of awareness of bruxism was higher among women than men in both cohorts (p65?<?0.01; p75?<?0.001). The 75-year-old subjects of both sexes reported bruxism less frequently than the 65-old subjects (Table?1) (p?<?0.001). The prevalence of problems to open the jaw wide and pain in the TMJ region was markedly (six to nine times) greater in subjects who did report than in those who did not report problems with TMJ sounds (Table?3). The prevalence distribution was similar in both age groups, but the prevalence of problems was higher among the 65- compared to the 75-year-old subjects. Subjects in both age groups who reported bruxism exhibited a significantly higher prevalence of TMD symptoms than those who were not aware of bruxism (Table?4). The distribution of the results was similar in both age groups although the prevalence was higher for TMJ sounds than for the other two symptoms.
