The use of carrageenan for limiting the mandibular movement in rats: A preliminary experimental study
Purpose: The objective of this study was to evaluate if the carrageenan may be used for limiting the mandibular movement. Material and Methods: Eighteen adult male Wistar rats were used for the research, 20 µl of carrageenan (4%) was infiltrated in the extra articular region, in front of the condyle to induce fibrosis. The rats were divided into groups according to the time of euthanasia (7, 15 and 30 days). Maximal mouth opening (MMO), mandibular deviation, initial and final weights were recorded and evaluated. After the euthanasia, the specimens were submitted to histological study in order to classify the inflammatory process using scores. Results: The mean differences between initial an…
Non-invasive joint decompression : an important factor in the regeneration of the bone marrow and disc recapture in temporomandibular arthropathies
Background This article aims to demonstrate the importance of the TMJ (Temporomandibular Joint) decompression in the treatment of degenerative processes and disc displacements, reporting two clinical cases treated with orthopedic and decompressive correction of TMJ. Material and Methods The studies reported in this article show patients with muscle and joint pain who were evaluated pre and post-treatment through MRI (Magnetic Resonance Irradiation) to follow-up bone marrow regeneration and TMJ disc placement. Transcutaneous electrical stimulation (TENS), measurement equipment and IO (Intraoral Orthotic) were used to evaluate and treat the patients. A critical review of literature has also b…
