Psychosomatie Characteristics of Patients with Mandibular Dysfunction

In Relation to Occlusal Appearance

Abstract

To find the role of psychosomatic characteristics as a factor of mandibular dysfunction, personality tests given to two groups of mandibular dysfunction patients were analyzed. These patients were divided according to the following mandibular dysfunction state; the first group being patients with unstable occlusion such as interference, premature contact, infraocclusion, open bite, and cross bite. The second group being patients with normal occlusion.
1) 25. 6% of the malocclusion group and 54. 5% of the normal occlusion group belonged to region III or N of the CMI test.
2) 18. 0% of the malocclusion group and 45. 5% of the normal occlusion group belonged to type B or E of the Y-G test.
3) 15. 4% of the malocclusion group and 54. 5% of the normal occlusion group belonged to the high anxiety group.
4) 16. 2% of the malocclusion group and 27. 3% of the normal occlusion groupb elonged to the “I'm not-OK, you are not-OK” group.
These results showed personality characteristics to be one factor in the ethiology of mandibular dysfunction.
