- Abstract
Aims. The aim of this paper was to assess the occlusal characteristics of a sample of patients with temporo-mandibular dysfunction. Materials and methods. 40 patients were included in this study, divided into two groups: in the first group, 20 patients were recruited from a private clinic in Cluj-Napoca all of them being diagnosed with temporo-mandibular dysfunction (TMD); the second group - the control group - included 20 subjects, chosen randomly, in the Department of Prosthodontics, Faculty of Dentistry. The inclusion criteria for the first group were: patients with TMD signs and symptoms, no history of trauma, no other organic sources of pain, no associated neuro-muscular diseases. The inclusion criteria for the control group were: clinically healthy patients, no history of trauma, no general history of disease with interest in the structures of the dento-maxillary apparatus, no orthognathic surgery and no ongoing orthodontic or prosthodontic treatment. Patients were examined clinically and the data obtained were statistically analyzed. Results. Statistical analysis revealed several significant results, such as the fact that subjects with TMDs had more frequent muscle pain (p = 0.018) and joint pain (p = 0.004). Also, for patients suffering from disc displacements without reduction, the presence of passive interference in protrusion was observed more often (p = 0.049), and for those with disc displacements with reduction, passive interference in laterality was more frequent (p = 0.010). Discussion. In the present study, interferences in maximum intercuspation (MI) and passive interferences in protrusion were found more frequently in the group of subjects with TMDs, which is consistent with the results in the literature. For subjects with disc displacements, significant differences were found between those disc displacements with reduction and, respectively, without reduction, regarding the passive interference in laterality and passive interference in protrusion, which may be due to the change of position of the articular disc and the trajectory of condylar movement during performing mandibular movements. Conclusions. No correlation has been shown between a certain type of occlusal dysfunction and a certain symptom of temporo-mandibular dysfunction. There are subjects who have occlusal dysfunctions without showing dysfunctional symptoms. Malocclusions may be correlated with dysfunctional signs.
