Relation between the severity of signs and symptoms of temporomandibular dysfunction and head posture

Our aim was to assess the relation between the severity of signs and symptoms of temporomandibular dysfunction (TMD) and head posture in individuals with and without dentofacial deformity class II and class III. The study was approved by the Ethics Committee of the Institution involved (protocol n° 2513/2007). Twenty-five patients with dentofacial deformity seen at the Craniomaxillofacial Surgery Outpatient Clinic of a public hospital participated in the study. Ten patients with a diagnosis of class II dentofacial deformity (mean age 24.4 years) were assigned to DG-II and 15 patients with a diagnosis of class III dentofacial deformity (mean age 24.1 years) were assigned to DG-III. The control group consisted of 15 volunteers (mean age 22.5 years) with no occlusal changes or clinical evidence of skeletal deformities. All participants answered a “Validated Protocol for Multiprofessional Centers for the determination of signs and symptoms of TMD”. Photographic evaluation of head posture was later performed by analysis of the head-neck angle. The Spearman correlation test was used for statistical analysis. A correlation coefficient of −0.249 and a p value of 0.370 were observed in the control group. The correlation coefficient was 0.103 and the p value 0.776 in DG-II and 0.126 and p 0.653 in DG-III. There was no correlation between the severity of signs and symptoms of TMD and the head-neck angle.
