OBJECTIVE: To evaluate success of pulpal anaesthesia of mandibular 1st molar by using 4% @entity21456 in buccal infiltration versus 2% @entity3303 in @entity616 . STUDY DESIGN: Randomized control trial. PLACE AND DURATION OF STUDY: Department of Operative Dentistry, Sardar Begum Dental College, Gandhara University, Peshawar, from March to August 2014. METHODOLOGY: One hundred and fifty-six emergency @entity1 , who had 1st molar diagnosed with irreversible @entity11624 , participated in the study. Subjects were divided into two groups by random allocation. One group received 4% @entity21456 buccal infiltration and the other group received @entity616 of 2% @entity3303 . Subjects_rsquo;self-reported @entity158 response was recorded on Heft Parker Visual Analogue Scale after local anaesthetic administration during access cavity preparation and pulp extirpation. RESULTS: Mean age of subjects was 31.46 _plusmn;10.994 years. The success rate of 4% buccal infiltration was 76.9%; whereas the success rate of 2% @entity3303 @entity616 was 62.8%. There was no statistically significant difference between the two groups. CONCLUSION: 4% @entity21456 buccal infiltration can be considered a viable alternative to 2% @entity3303 @entity616 in securing successful pulpal anaesthesia for endodontic therapy.
