FLORES-MAS, Ricardo. Bone morphology of the temporomandibular joint in patients with Parkinson’s disease. Rev. Estomatol. Herediana [online]. 2014, vol.24, n.4, pp.248-255. ISSN 1019-4355.

Objective: To investigate the morphological alterations of temporomandibular joint in patients with Parkinson’s disease. Determining condyle-fossa relationship, concentric position of the condyles and the dimensional and positional symmetries between the right and left condyles. Methods: 20 subjects 45-80 years of age with Parkinson’s Disease time of 6-9 years. Where performed CT scan of the temporomandibular joints. The images obtained from axial views evaluated possible asymmetries in the size and position between the condylar process. Likewise, sagittal sections were used to assess the depth of the mandibular fossa, the condyle-fossa relationship, and concentric position of the condyles in patients with the Parkinson’s disease. It was decided to use the Student t test for independent samples and the test of Mann-Whitney U. All tests were worked at a significance level of 5%. Results: No significant asymmetries were found in the temporomandibular joints for both the right and left side of this sample. The findings differ from the results of other studies in patients without Parkinson’s disease. Conclusion: Of all the evaluated measurements, no statistically significant differences between the right and left sides was found. 90% have no geometric center, showing a difference of 2.45 mm between the right and left side. Evaluation of the concentric position of the condyles in their mandibular fossa showed no concentric positioning for the 2 sides.
