DC/TMD Axis I diagnosis criteria wasused for the clinical examination of pain disorders andtemporomandibular joint (TMJ) disorders. Also, in DC/TMD Axis I, The TMD Pain Screener, focusing on painwithin the last 30 days, was used. In DC/TMD Axis II evaluation, the Jaw Functional Limitation Scale-8 (JFLS-8) waspreferred to detect symptom severity and functional limitations. The data analysis was conducted by using theChi-square, Kruskal Wallis test, and the Bonferroni correction for the Mann-Whitney U test.RESULTS: Out of 128 patients, 120 patients (93.75%) hadTMJ disorders that were accompanied by muscle pain disorders. The effect of gender and age on TMJ/muscle paindisorders was not significant (TMJ disorders; p=0.123,p=0.263; Muscle pain disorders; p=0.145, p=0.100, respectively). According to JFLS-8, the limitation in mastication(item 1 and 2) and joint mobility (item 4) were major complaints in the group of patients with ‘disc displacementwithout reduction with limited opening’ compared to theother TMJ disorders (p=0.001, p=0.004, p=0.007, p<0.008).CONCLUSION: DC/TMD Axis I is a significant reference toclinicians in the diagnosis and evaluation of TMD. In DC/TMD Axis II, JFLS-8 is an efficient instrument for the measurement of functional limitation associated with temporomandibular disorders.eninfo:eu-repo/semantics/openAccessArticle10.17214/gaziaot.56754437116448474
