Temporomandibular disorders (TMD) are disorders that affect the joint between the temporal bone on the side of the head and the mandibular (jaw) bone of the face, and the associated muscles. Pain is the defining feature of TMD and the primary reason for seeking care. TMD may also involve joint noises or restricted jaw function or both. Different medicines are used to treat pain due to temporomandibular disorders (TMD). These include simple painkillers (analgesics) and medicines which reduce inflammation and treat pain (for example, non-steroidal anti-inflammatory drugs, corticosteroids). Medicines (called benzodiazepines) are sometimes used to reduce tension and spasm in the muscles affected by TMD. In addition, some antidepressant medicines (called tricyclic antidepressants) are used in low doses to help patients with TMD and are thought to be effective because they reduce muscle tension in patients who grind their teeth. This review found that there was not enough evidence to decide which medicines are effective in reducing pain due to chronic TMD.
مطالعه چکیده کامل
Temporomandibular disorders (TMD) are a group of disorders affecting the temporomandibular joints and the muscles of mastication. TMDs are treated with a wide range of drugs. The extent to which the use of these drugs is based upon evidence is unknown.
اهداف
To assess the effectiveness of pharmacological interventions both alone and in combination with non-pharmacological therapy in relieving pain in patients with chronic TMD.
روشهای جستوجو
Electronic searches of the Cochrane Oral Health Group's Trials Register (2 August 2010), CENTRAL (The Cochrane Library 2010, Issue 3), MEDLINE via OVID (1950 to 2 August 2010), EMBASE via OVID (1980 to 2 August 2010) and CINAHL via EBSCO (1981 to 2 August 2010) were conducted. Reference lists of articles and previous reviews were scanned for relevant articles and authors were contacted for further information where appropriate.
معیارهای انتخاب
Randomised controlled trials (RCTs) in which a pharmacological agent was compared with placebo for the management of pain in patients with TMD. Parenteral routes of administration were excluded.
گردآوری و تجزیهوتحلیل دادهها
Duplicate data extraction and assessment of risk of bias in included studies was performed.
نتایج اصلی
Eleven studies were included with a total of 496 participants. The primary outcome of most of the studies was pain. The risk of bias in the included studies was variable. Whilst four studies showed significant pain relief for the active treatment, three were of poor quality. Most adverse effects were mild to moderate in severity. Four studies reported withdrawals due to severe adverse reactions, but insufficient information was provided regarding the trial groups from which the withdrawals occurred. No meta-analysis was conducted due to lack of similarities across the included studies.
نتیجهگیریهای نویسندگان
There is insufficient evidence to support or not support the effectiveness of the reported drugs for the management of pain due to TMD. There is a need for high quality RCTs to derive evidence of the effectiveness of pharmacological interventions to treat pain associated with TMD.
