Abstract
Background: Temporomandibular disorder (TMD) is a fairly common disease, affecting the quality of life of patients. To evaluate the treatment outcome toward temporomandibular disorder with occlusal splint, we conducted this study. Objectives: Description of clinical features, images of the temporomandibular joint on cone-beam computed tomography (CBCT) in patients with temporomandibular disorders and evaluation of treatment results with stable occlusal splint. Materials and methods: A cross-sectional descriptive study with clinical intervention was carried out to evaluate treatment outcome before and after intervention. Results: The female-to-male ratio of patients with signs and symptoms of temporomandibular disorder was 4:1. The signs and symptoms occupied the highest proportion were pain (100%), followed by joints sounds (82.9%), decreased amplitude of mouth opening (48.6%). The condylar position was in posterior side with 67.5% of cases. After 6 months of treatment: 34.3% and 65.7% of patients showed a high and average reduction of pain respectively, 100% of patients showed a good improvement in mouth opening amplitude, 96.6% and 3.4% of patients showed an average and high decrease of joint sound, respectively. Conclusion: Temporomandibular disorder is more common in women than in men, the main symptom that patients come for treatment is joint pain. The condyle morphology on cone-beam computed tomography film is round and in posterior position. After 6 months of treatment with occlusal splint, 100% of patients responded to the treatment regarding pain, limitation in mouth opening and joint sound. The position of the mandibular condyle in the group with central position increased by 60%.
