Abstract:
Objective:To investigate the relationship between CBCT imaging changes of condyle and clinical features,and related risk factors in patients with temporomandibular disorders(TMD).Methods:453 patients with TMD were enrolled and underwent CBCT scan for bilateral temporomandibular joints(TMJ),3D reconstruction of the TMJs was analyzed.Logistic regression analysis was performed to investigate the relationship between condylar bone changes and TMD clinical features.Results:Patients＜18 years old were more likely to have condylar bone changes than the adults.The symptoms of pain and restricted mouth opening were more likely to be detected in the condylar bone change group(n=133)than in the normal condylar bone group(n=320).The incidence of brux-ism in the normal condylar bone group was higher than that in the condylar bone change group.Univariate logistic regression analysis showed that only bruxism(OR=0.550),pain(OR=1.844)and mouth restriction(OR=2.024)were included in the regression equa-tion.Multivariate logistic regression analysis showed that,due to the protective effect of bruxism,the OR value of pain decreased from 1.844 to 1.791,and the OR value of mouth restriction decreased from 2.024 to 1.847.Conclusion:The condylar bone change in TMD patients more likely occur in puberty or patients with pain and restricted mouth opening.Bruxism may be a protective factor in the occurrence of condylar bone changes in TMD patients.
