Brief summary
EMLA is proven to be better in achieving pain control as topical anesthesia than benzocaine at palatal mucosa. So this research is done to compare its effectiveness at buccal mucosa. Methods: A total number of 70 patients attending DOW ojha hospital, fulfilling inclusion criteria and undergoing extraction of bilateral teeth will be included in this study. Approval of data collection will be sought from the Institutional ethical review board ¬(IERB) of Dow university of health sciences (DUHS) for this study. the participants will be briefed about the nature and purpose of the study including visual analogue scale (VAS). They will be ensured that their information will be used for the study purpose only. Informed consent from the participants will be obtained. Complete history from patients will be taken. The sites will be divided into condition A- 5% EMLA and Condition B - 20% Benzocaine Gel. After marking injection sites, principal investigator will leave the room and the consultant will apply 5% EMLA gel at experimental area and 20% Benzocaine gel at control area. After pre-treatment with topical anesthesia the consultant will administer local anesthesia to both sides. Then Principal investigator will be signaled into the room and patient will be assessed though visual analogue scale by him and will be confirmed by supervisor.
Detailed description
The concept of dental pain is a true fear for many people. In dentistry, management of pain and anxiety has evolved through behavior modification and oral and intravenous sedatives. Whereas local anesthesia is known as the backbone of the profession. Over the years, methods have been introduced to reduce the pricking pain of local anesthesia injection. There are so many factors which help reduce the pain caused by local anesthesia injection such as warming the local anesthetic agent, specific size of needle gauge, a certain type of anesthetic solution and topical anesthetics. Topical anesthetics are used at insertion sites before injections to reduces the slight discomfort with insertion of the needle. \[1,2,3\] OneaofatheaTopicalaanesthetics widelyaused for dental proceduresaincludesaBenzocaine.\[4\] Benzocaine is anaFDA-approved drugawhichaisaavailable in various forms and concentrations. In the 20% concentration, benzocaineagel is the most commonly used topical anesthetic in dentistry, withaanaonsetatimeaofa30asecondsaandadurationaofa5-15aminutes. EMLA is a eutectic mixture of the two local anesthetics, prilocaine and lidocaine which melt at lower temperatures than any of its components, permitting higher concentrations of anesthetics for use.\[5\] It is used to reduce the pain associated with venous cannulation. Past studies have reported the pharmacologic and the psychological effects on pain control by benzocaine and Eutectic mixture of local anesthetics (EMLA).
