The secondary objective was to observe the correlations of the 2\u2010PD test with regard to pain intensity and psychological and disability variables.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Intra\u2010 and interexaminer reliability of 2\u2010PD in the trigeminal region was assessed in 40 asymptomatic individuals and 54 patients with TMD.

Statistically significant differences (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a0.001) were obtained between the asymptomatic participants and the patients with TMD regarding the mean values from trials of the three trigeminal branch measurements, with a large effect size.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Reliability of the 2\u2010PD test was considered good\u2010moderate. Patients with TMD showed greater distances in the 2\u2010PD test, suggesting that tactile acuity in the trigeminal region is impaired in patients with TMD. Assessment of tactile acuity with 2\u2010PD test in patients with TMD should be considered
