Brief summary

Temporomandibular disorders (TMDs) are one of the most common muco-skeletal disorders, seen in the dental clinics. Many factors work together to initiate or aggravate the condition, so it is a multifactorial disorder. The etiology of TMDs may be a result of parafunctional habits such as clenching and bruxism, acute trauma to the jaw, trauma from hyperextension e.g. after a long dental treatment, joint laxity, psychological distress, occlusal disharmony like presence of high crown or free-end saddle leading to joint instability or systemic diseases such as Rheumatoid arthritis or Osteoarthritis. The aim of this study was to evaluate the effects of naproxen sodium+codeine phosphate, naproxen sodium+dexamethasone, and naproxen sodium on pain in patients complaining from temporomandibular pain.

Interventions

DRUGnaproxen sodium+codeine phosphate, naproxen sodium+dexamethasone, naproxen sodium, paracetamol

NSAID, steroid, opioid, paracetamol and combinations of this drugs can be used in temporomandibular disorders.

Naproxen Sodium+Codeine Phosphate
Naproxen sodium is a propionic acid derivative with analgesic, antipyretic, and antiinflammatory properties. Its mechanism of action relies on the inhibition of prostaglandin synthesis, and significant pain relief and plasma levels can be obtained within 20 minutes following intake. The elimination half-life of naproxen sodium is reportedly around 14 hours, and naproxen sodium is used in doses ranging from 275 to 550 mg in surgical procedures. Codeine phosphate is an opioid analgesic which has similar applications to those of morphine. However, it is significantly less potent as an analgesic and has only mild sedative effects. The drug's principal site of action is at the µ-opioid receptors (MOR) which are distributed in the central nervous system. Peak effect is reached within 2 hours and analgesic action continues for approximately 4 hours. Naproxen sodium (550 mg)+codeine phosphate (30 mg) was used twice daily in this study. naproxen sodium+codeine phosphate, naproxen sodium+dexamethasone, naproxen sodium, paracetamol: NSAID, steroid, opioid, paracetamol and combinations of this drugs can be used in temporomandibular disorders.

The elimination half-life of naproxen sodium is reportedly around 14 hours, and naproxen sodium is used in doses ranging from 275 to 550 mg in surgical procedures. Naproxen sodium (550 mg) was used twice daily + dexamethasone (8 mg) was used once daily in this study. naproxen sodium+codeine phosphate, naproxen sodium+dexamethasone, naproxen sodium, paracetamol: NSAID, steroid, opioid, paracetamol and combinations of this drugs can be used in temporomandibular disorders.

Paracetamol
Paracetamol is a mild analgesic and antipyretic, and is recommended for the treatment of most painful and febrile conditions, for example, headache including migraine, toothache, neuralgia, colds and influenza, sore throat, backache, rheumatic pain and dysmenorrhoea. naproxen sodium+codeine phosphate, naproxen sodium+dexamethasone, naproxen sodium, paracetamol: NSAID, steroid, opioid, paracetamol and combinations of this drugs can be used in temporomandibular disorders.
