Distribution of diagnoses in a population of patients with temporomandibular disorders

Prevalence of temporomandibular joint disorders in a Mexican elderly group.

“…Prevalence was similar among men and women, results that differs with most other studies 1,2,5,[7][8][9][10]13,14,16,[19][20][21][22][23][24][25] , except with the findings reported by Dallanora et al 12 in the Brazilian population. TMD distribution per group according to DC/TMD varies between studies: Manfredini1 observed a higher prevalence of group I TMD, Caselín et al 9 of group II, and Guarda-Nardini 15 of group III.…”

“…Therefore, the study of TMD in other age groups, such as the elderly population, is also very relevant 7,10,12,[15][16][17][18] . In addition, many studies suggest that TMD has a higher prevalence in women 1,2,5,[7][8][9][10]13,14,16,[19][20][21][22][23][24][25] , except in the study conducted by Dellanora et al 12 , in which no differences between both sexes were observed. Prevalence by type of TMD in each group, according to the diagnostic criteria for temporomandibular disorders (DC/TMD), is also very variable.…”

“…Group I shows no difference with groups II and III 1,9,20 . With respect to the type of TMD, displacement with disc reduction is the most frequent disorder 1,11,14,[18][19][20] , followed by muscle disorders 16,19,20,21,26 , myofascial pain 9,11,[13][14][15]20 and arthralgia 14,20,26 .…”

Disfunção temporomandibular em gestantes

“…The literature suggests that it is 1.5 to 2 times more prevalent in females as compared to males and that 80% of patients treated for TMD are females [2][3][4] . The severity of symptoms is also related to patients' age, with peaks at reproductive age, with the highest prevalence in females aged between 20 and 40 years 5,6 , and low prevalence in children and older adults 6,7 .…”

“…Most individuals looking for TMD treatment are females in reproductive age 5,6 , however there is still no consensus in the literature about the reason for the higher prevalence among females 6 . Highest TMD prevalence at reproductive age, added to the pattern of starting after puberty, higher association to pre-menstrual period and lower prevalence in the post-menopausal period suggest that female hormones may play important role in TMD etiology or maintenance 6,8,9 .…”
