Local anesthesia in the oral cavity is a pain full experience for the patient. All means should be made to reduce the pain and anxiety of the patient for needle stick procedures. My study aims in elevating the pain experienced by the patient during this procedure by using either cold application with ethyl chloride or 5% lidocaine gel.

Local anesthetic procedure is always a dreadful experience for the patient specially for the patients who are already in pain . It is a job of the dentist to provide a painless dental treatment from the very beginning. Most dental procedures require administration of local anesthesia for a painless procedure with local anesthesia procedure being painful itself with the administration of needle in the oral cavity. Dentist everyday in their practice utilise various techniques and procedures in alleviating this painful experience with either application of lidocaine gel or spray . Numbing the oral mucosa with cold application is well documented and tested therefore my study aims in application of ethyl chloride spray on cotton pallet for a duration of 30 seconds in producing the desired numbing effect of the oral mucosa before infiltration of local anesthesia in alleviating the needle prick sensation perceived by the patient.
