Efficacy of prolotherapy and arthrocentesis in management of temporomandibular joint hypermobility.

OBJECTIVE: The aim of this study was to compare the efficacy of dextrose prolotherapy in conjunction with arthrocentesis and dextrose prolotherapy alone in the management of symptomatic TMJ hypermobility. METHODS: Twenty-four patients suffering from TMJ symptomatic hypermobility received 10% dextrose injections for three sessions at four-week intervals. Twelve patients (P group) received prolotherapy alone; the other 12 (PA group) also underwent a single arthrocentesis session. Patients were evaluated for maximal incisal opening, maximal incisal opening without pain, pain at rest, pain during chewing function, TMJ sound, and locking episode frequency. RESULTS: Pain scores were significantly reduced in both groups, and the locking episode frequency was decreased to a greater extent in the PA than the P group, at both the short and long terms. CONCLUSION: Prolotherapy is effective in the management of TMJ hypermobility. However, prolotherapy with arthrocentesis may be superior to prolotherapy alone in the management of TMJ hypermobility.

The effectiveness of the masseteric nerve block compared with trigger point injections and dry needling in myofascial pain.

OBJECTIVE: To compare the efficacy of three different treatment methods in the management of myofascial pain: masseteric nerve block (MNB), trigger point injection with local anesthetic (LA), and dry needling (DN). METHODS: Forty-five patients diagnosed with myofascial pain and trigger points in masseter muscles were treated with MNB (n = 15), DN (n = 15), and trigger point injection with LA (n = 15). Pain on palpation (PoP), pain on function (PoF), and maximum mouth opening (MMO) scores were measured and compared before the injections and all follow-ups after the injections. RESULTS: MMO values were significantly increased in each group. The decrease in PoF values was statistically significant between the groups at 12 weeks (baseline time period). DISCUSSION: Results of the present study indicate that MNB was not as effective as trigger point injection with local anesthetic or dry-needling in the management of masticatory myofascial pain.

Results of Combined, Single-Session Arthrocentesis and Dextrose Prolotherapy for Symptomatic Temporomandibular Joint Syndrome: A Case Series.

OBJECTIVE: Arthrocentesis and prolotherapy are nonsurgical treatments for temporomandibular joint (TMJ) diseases. This study aimed to evaluate the treatment of hypermobility, pain, and displacement of the TMJ by consecutively performing arthrocentesis and prolotherapy in the same session. MATERIALS AND METHODS: In this study, 10 adults with disc displacement and painful, hypermobile TMJ were selected. Arthrocentesis and prolotherapy were consecutively performed using a 30% dextrose solution that was simultaneously injected into five areas: posterior disc attachment, superior joint space, superior and inferior capsular attachments, and stylomandibular ligament. Paired t-test, McNemar test, and chi-square test were used to assess the maximum mouth opening, clicking sounds, pain, and subluxation of the TMJ. Patients with rheumatoid arthritis and parafunctional habits such as teeth clenching and grinding and biting of the cheeks or any other objects and those who had undergone surgery were excluded from this study. RESULTS: A total of 10 participants (36.20 ± 7.06 years old, 7 women and 3 men) received a single treatment session of combined arthrocentesis and prolotherapy at the same office visit. Subluxation frequency and pain significantly decreased after the first week of treatment (p < 0.05). Subluxation also decreased at the 3-month follow-up (p < 0.05). Clicking sound values did not significantly change at any of the follow-up time points. Maximum mouth opening values decreased at all follow-up time points compared to baseline (p < 0.05). CONCLUSION: A single session of combined arthrocentesis and prolotherapy to treat symptomatic TMJ safely and significantly improved the subluxation and pain after 1 week and subluxation after 3 months compared to baseline status. The maximum mouth opening significantly decreased at all follow-up time points. Future studies assessing multiple treatment sessions are warranted.

Short-term results of prolotherapy in the management of temporomandibular joint dislocation.

OBJECTIVE: Prolotherapy, the rehabilitation of ligaments or tendons by induced proliferation of cells by using dextrose, is a noninvasive and effective method for the treatment of temporomandibular joint (TMJ) dislocation. The aim of this study was to evaluate the efficacy of prolotherapy method for the management of acute or chronic dislocation of TMJ. MATERIALS AND METHODS: In this study, 10 patients with TMJ dislocation (2 acute, 8 chronic) were examined retrospectively. All patients consisted of female patients, with a mean age of 28.4, who were treated with prolotherapy procedure. Differences of visual analog scale scores in quality of life, pain on function, and chewing function efficacy between sessions were investigated using the Wilcoxon t test and median values of sessions were evaluated using the Kruskal-Wallis H test. The amount of change at the maximum mouth opening occurring between the preoperative and postoperative values and the frequency of locking episodes were calculated, with results considered statistically significant at P < 0.05. RESULTS: Pain on function scores were significantly decreased in all patients, and TMJ locking were not observed during the follow-up period. Maximum mouth opening exhibited a tendency to decrease, but it was not statistically significant. Also, clicking sound on function presented no significant change (P > 0.05). On the other hand, the visual analog scale scores for quality of life showed significant improvement in all patients (P < 0.05). CONCLUSIONS: The results of this study show that prolotherapy can be used as an efficient, simple, and conservative method to treat TMJ dislocation.
