Abstract

This comparative study was conducted on twenty patient selected and distributed on two groups with the help of flip coin method. All patients should meet the inclusion criteria of having anterior disc displaced with reduction associated with pain(painful clicking affected temporomandibular joint).Each of the two selected group undergoes arthrocenthesis under local anaesthesia(by delivering auriculotemporal nerve block type anaesthesia in the affected temporomandibular joint). By using the shepard cannula(specially designed cannula for temporomandibular joint arthrocenthesis) using 50cc of lactate ringer's solution(the minimum amount of lavage solution stated by the litreature) and at the end of the surgery each of the 2 groups received intraarticular temporomandibular joint injection with either Curavisc (groupA)or Epicotil(Group B).Then the patient was followed on regular basis on 2,4,and 12weeks intervals by assessing and evaluating the pain intensity using the verbal numerical rating score (V.N.R.S).the study conclusion revealed that Epicotil(pain receptor blocking agent) 20mg/2ml was much more reliable in alleviating pain intensity than Curavisc(lubrication system)
