Effectiveness of Anterior and Middle Superior Alveolar Nerve Block for Anesthesia of Maxillary Teeth Using Conventional Syringe: A Randomized Prospective Study

AIM: To study the effectiveness of anterior and middle superior alveolar nerve block (AMSA) for anesthesia of unilateral maxillary teeth, i.e., from central incisor to second premolar of the same side by using conventional syringe and needle. MATERIAL AND METHOD: Two hundred patients who needed extraction of any tooth/teeth in the region of central incisor to second premolar of the same side were randomly chosen for the study. RESULT: Successful anesthesia was found in 71.5% of cases. However, the highest success rate was seen with first premolar (82.2%) and minimum with lateral incisor (67.5%), and induction time ranged from 6 to 12 min and duration for 30–45 min. CONCLUSION: Using conventional syringe and needle, AMSA can be administered to achieve adequate soft tissue anesthesia of maxillary central incisors, canine and premolars of that side and pulpal anesthesia to a good extent (more so with first premolar), without affecting the muscles of facial expressions and lip numbness, reducing the requirement of multiple injections for the same.
