Myofascial pain with or without mouth opening limitation was the commonest diagnosis in TMD patient population s , and disc displacement with reduction was the commonest diagnosis in community sample
The prevalence of myofascial pain and its association with occlusal factors in a threshold country non-patient population
The objective of the study is to assess the prevalence of myofascial pain in a threshold country and to isolate occlusal risk factors . One hundred and seventy-one r and omized selected women were examined by a trained examiner in accordance with the Research Diagnostic Criteria for Temporom and ibular Disorders ( RDC/TMD ) examination procedure . Subscales of the SCL 90-R , grade d chronic pain status , and anamnestic question naires were also used .  Logistic regression  was performed to compute the odds ratios for six common occlusal features with regard to the presence of myofascial pain , in accordance with the RDC/TMD criteria . Fifteen subjects ( 15 / 151 = 9.93 % ) suffered from myofascial pain . Results from logistic regression analysis showed that non-occlusion ( posterior teeth , at least one side ) and open bite increased the risk of myofascial pain . The prevalence of myofascial pain in this study is comparable with that in another study , in a highly industrialized environment , in which the RDC/TMD was used . The role of occlusion in a non-patient population seems to be restricted to serious alterations of normality . This article presents the prevalence of myofascial pain and its association with occlusal factors . This issue will help the clinicians to assess the influence of occlusion in myofascial pain patients and to send the patient to the appropriate specialist
