Study on the use of temporomandibular joint dysfunction index in temporomandibular disorders.

OBJECTIVE: To study the methodological techniques in measuring the severity of temporomandibulr disorders (TMD) and in evaluating the effectiveness of therapies in clinic. METHODS: Both Fricton's Craniomandibular Index (CMI) and Helkimo's Clinical Dysfunction Index were calculated from 60 TMD patients. Inter-rater reliability was tested to assess the consistency in use between different examiners. Fricton's CMI was used to assess the clinical improvement after accepting a treatment in 21 TMD patients diagnosed as acute disk displacement without reduction. RESULTS: Correlation Coefficient for inter-rater reliability in two groups was 0.879 and 0.939 respectively for Fricton's CMI and 0.744 and 0.838 for Helkimo Clinical Dysfunction Index. Fricton's TMJ dysfunction index was decreased from 0.337 to 0.021 (P < 0.001) and Fricton's CMI was decreased from 0.185 to 0.011 (P < 0.001) after the treatment in 21 TMD patients with disk displacement without reduction. CONCLUSIONS: To avoid using subjective and descriptive report in assessment of the severity of TMD and the effectiveness of therapies, Fricton's CMI is recommended as an objective criteria which is simple in clinical use, and ease in scoring.

Autogenous reconstruction of the temporomandibular joint.

Recently, the temporomandibular joint has been reconstructed with a variety of alloplastic materials; however, functional results are often limited, and long-term stability of the reconstruction is questionable. In contrast, costochondral rib grafting with rigid internal fixation and a temporoparietal fascia flap allows complete functional reconstruction of the temporomandibular joint with autogenous tissue. Thirteen joint reconstructions in 11 patients were followed for up to 7 years and stability of the reconstruction was confirmed. The anterior incisal opening improved from a mean of 14 to 31 mm. Normal occlusal relationships were either reestablished or preserved. Joint pain was ameliorated. The preferred reconstruction of the temporomandibular joint is by autogenous tissue for disc and joint replacement. The treatment provides primary therapy in total joint reconstruction where tumor, trauma, or failed prosthetic joint replacement necessitate complete reconstruction.

Pumping injection of sodium hyaluronate for patients with non-reducing disc displacement of the temporomandibular joint: two year follow-up.

Objectives: The purpose of the present study was to examine the long-term effect of pumping injection of sodium hyaluronate into the TMJ in patients with non-reducing disc displacement. Patients: Sixty patients with non-reducing disc displacement underwent pumping injection of sodium hyaluronate (pumping group). Seventy-six patients with non-reducing disc displacements were observed without any active treatment (observation group). Study design: In both patient groups clinical signs and symptoms were observed periodically for 2 years. Variables such as age, range of maximum mouth opening, angle of posterior slope of the articular eminence and degenerative bony changes of the condyle at the initial visit were also examined. Cox hazards analysis was applied to examine the clinical outcome for such variables in addition to the results of pumping injection of sodium hyaluronate. Results: Pumping injection of sodium hyaluronate seemed to have a favourable effect when compared with the control group (untreated) (p=0.0002). However, the four background variables mentioned could not be explained as predictors of outcome. Conclusion: Pumping injection of sodium hyaluronate seems to be effective for non-reducing disc displacement of the temporomandibular joint.

The middle cranial fossa approach in managing lesions of the temporomandibular joint.

The temporomandibular joint (TMS) lies at the skull base. Its bony roof forins part of the floor of the middle cranial fossa. It is bounded by the infratemporal fossa, external auditory canal, middle ear, and eustachian tube. When wide resection of tumors arising within the TMJ is necessary, skull base approaches permit complete resection with oncologically sound margins. Precise pathologic diagnosis can be difficult and extra care should be taken to ensure diagnostic accuracy. Outcomes are improved if attention and effort is directed to rehabilitation of the TMJ. Five such cases are presented and the literature is reviewed.

Temporomandibular joint osteoarthritis and crystal deposition diseases: a study of crystals in synovial fluid lavages in osteoarthritic temporomandibular joints.

To study the presence of crystals in synovial fluid lavages of osteoarthritic temporomandibular joints (TMJs), in order to evaluate the possible role of these crystals in the osteoarthritic (OA) process, synovial fluid lavage samples of the upper joint compartment from 44 TMJs were obtained prior to arthroscopy. The OA group consisted of 32 TMJs. The control group consisted of 12 TMJs that had been diagnosed with other nonosteoarthritic conditions. The lavage samples were analysed as wet preparations, unstained and stained, with ordinary light, polarized light and compensated polarized light for the presence of crystals and white blood cells. One sample was prepared for subsequent electron microscopic (EM) examination. Synovial fluid lavage analysis of osteoarthritic TMJs did not show any monosodium urate monohydrate or calcium pyrophosphate dihydrate crystals. However, in three lavages, particles which possibly contained calcium were identified with alizarin red S staining. White blood cells were occasionally seen. Synovial fluid analysis of the lavages of the control TMJs did not reveal any crystals. EM examination of synovial fluid lavage from an osteoarthritic TMJ failed to clearly show crystal formation. Concurrence of TMJ crystal deposition and OA appears less prominent than in other synovial joints. We conclude that crystals probably do not play an important role in TMJ OA.

Clinical comparative study of microcurrent electrical stimulation to mid-laser and placebo treatment in degenerative joint disease of the temporomandibular joint.

Mid-laser and microcurrent stimulation (MENS) have been found to be effective in the reduction of painful temporomandibular joints (TMJ) with internal derangement. There was significant improvement in mobility with the reduction of pain. Mid-laser was superior to MENS in its application and effect, and both were significantly better than the placebo treatment.

Pathogenesis of degenerative joint disease in the human temporomandibular joint.

The wide range of disease prevalences reported in epidemiological studies of temporomandibular degenerative joint disease reflects the fact that diagnoses are frequently guided by the presence or absence of non-specific signs and symptoms. Treatment is aimed at alleviating the disease symptoms rather than being guided by an understanding of the underlying disease processes. Much of our current understanding of disease processes in the temporomandibular joint is based on the study of other articular joints. Although it is likely that the molecular basis of pathogenesis is similar to that of other joints, additional study of the temporomandibular joint is required due to its unique structure and function. This review summarizes the unique structural and molecular features of the temporomandibular joint and the epidemiology of degenerative temporomandibular joint disease. As is discussed in this review, recent research has provided a better understanding of the molecular basis of degenerative joint disease processes, including insights into: the regulation of cytokine expression and activation, arachidonic acid metabolism, neural contributions to inflammation, mechanisms of extracellular matrix degradation, modulation of cell adhesion in inflammatory states, and the roles of free radicals and heat shock proteins in degenerative joint disease. Finally, the multiple cellular and molecular mechanisms involved in disease initiation and progression, along with factors that may modify the adaptive capacity of the joint, are presented as the basis for the rational design of new and more effective therapy.

Silicon in temporomandibular joint ankylosis surgery.

Temporomandibular joint ankylosis frequently occurs succeeding untreated or not adequately treated mandible fractures. Treatment of this condition with combined condylectomy and silicon sheet/block application was investigated in the literature. Thirty-eight patients with temporomandibular joint ankylosis were included in this study, and postoperative results were presented. Mean preoperative and postoperative sixth-month interincisor opening values were 5.8 and 28.8 mm, respectively. In two patients (5.2%), another operation to remove silicon material was needed because of infection and exposure of the silicon. One patient (2.6%) was operated on again for limited mouth opening. It was concluded that interpositional arthroplasty with silicon was proved to be a low-cost, easy approach with satisfactory long-term results.

Hyaluronate for temporomandibular joint disorders.

BACKGROUND: Temporomandibular joint disorders (TMD) refer to a group of heterogeneous pain and dysfunction conditions involving the masticatory system, reducing life quality of the sufferers. Intra-articular injection of hyaluronate for TMD has been used for nearly two decades but the clinical effectiveness of the agent has not been summarized in the form of a systematic review. OBJECTIVES: To assess the effectiveness of intra-articular injection of hyaluronate both alone and in combination with other remedies on temporomandibular joint disorders. SEARCH STRATEGY: Intensive electronic and handsearches were carried out. The Oral Health Group's Trials Register (September 2001), The Cochrane Library CENTRAL database (Issue 3, 2001), MEDLINE (1966- May 2001), PubMed ( up to March 2002), EMBASE (1974 - August 2001), SIGLE (1980 - December 2001), CBMdisc (1983 - July 2001, in Chinese) and Chinese Medical Library were searched. All the Chinese professional journals in the oral health field were handsearched and conference proceedings consulted. There was no language restriction. SELECTION CRITERIA: Randomized or quasi-randomized controlled trials (RCTs), with single or double blind, design testing the effectiveness of hyaluronate for patients with temporomandibular joint disorders. DATA COLLECTION AND ANALYSIS: Two reviewers independently extracted data, and three reviewers independently assessed the quality of included studies. The first authors of the selected articles were contacted for additional information. MAIN RESULTS: Seven studies were included in the review. Three studies, including 109 patients with temporomandibular disorders, compared hyaluronate with placebo. Long term effects (three months or longer) are in favour of hyaluronate for the improvement of clinical signs/overall improvement of TMD (RR=1.71, 95%CI: 1.05, 2.77) from two of the studies (n=71). However, this conclusion was not stable enough at sensitivity analysis. Three studies provided data from 124 patients for the comparison of hyaluronate with glucocorticoids (one study also included a placebo group). Hyaluronate had the same short term and long term effects on the improvement of symptoms, clinical signs or overall conditions of the disorders as glucocorticoids. When comparing the effect of arthroscopy or arthrocentesis with and without hyaluronate, results were inconsistent. Hyaluronate had a potential in improving arthroscopic evaluation scores. Mild and transient adverse reactions such as discomfort or pain at the injection site were reported in the hyaluronate groups. No quality of life data were reported REVIEWER'S CONCLUSIONS: There is insufficient, consistent evidence to either support or refute the use of hyaluronate for treating patients with TMD. Further high quality RCTs of hyaluronate need to be conducted before firm conclusions with regard to its effectiveness can be drawn.
