Clinical Research On Relationship Between The Curve Of Wilson And Temporomandibular Joint Disorders In Teenagers

Objective:To investigate the relationship between the angular of curve of Wilson(COW)and temporomandibular joint disorders(TMD)in teenagers.Methods:A total of 105 undergraduates who volunteered without TMD and teenage patients with TMD visiting the First Affiliated Hospital of Xinjiang Medical University from January to August 2017 were recruited in the study.The subjects were divided into the TMD group and the normal control group,and the subjects were examined for the symptoms of muscle pain and sounds of the temporomandibular joint(TMJ),The angular curve of Wilson were measured by CBCT.Related data were analyzed statistically with one-way analysis of variance and t-test.Results : The difference was statistically significant between the COW of TMD group and the normal control.The average angle of COW in TMD group is greater.The angular of Molar buccal lingual inclination of ipsilateral of patients with TMJ sounds was significantly larger than the opposite side of no sounds;while contralateral the angular of Molar buccal lingual inclination of patients with TMJ sounds had no significant differences with those of normal groups.There was no statistically significant difference in the COW between the patients with and without muscle pain.Conclusion:TMD patients with TMJ sounds showed a deeper COW than normal controls.The angular of Molar buccal lingual inclination of ipsilateral of patients with TMJ sounds was significantly larger than the opposite side of no sounds.A larger COW causes an increased risk of TMD disease.The TMD muscle pain symptoms were no significantly relation.
