The usual cause that makes the patient requesting doctor advice is pain which is commonly found in many temporomandibular joint disorders (TMDs). TMDs don't follow simple etiological pathway nor simple treatment protocol and majority of these treatments protocols are targeted to pain therapy which is carried out using opioid and/or non-steroidal anti-inflammatory drugs (NSAIDs) and these drugs carry many side effects, thus there is great interest to patients as well as to clinicians to develop new kinds of treatments which are more effective and safer. low-level laser therapy with infra-red spectrum are good to treat deeply damaged tissues, such as that in TMDs without side effects but the optimum wavelength and energy density is still unknown. This study was done to assess anti nociceptive and analgesic effectiveness of 940 nm low level diode laser using two energy density 171 and 74 J/cm2 by formalin test which is a valid well documented technique to assess analgesic, and comparing the results with control groups and diclofenac pretreated group. The results showed that LLLT significantly reduced the nociceptive responses induced by formalin. It was concluded that LLLT with energy density 74J/cm2 had very good anti nociceptive effect.
