• Study Type: interventional
• Target: 40
• Locations: 0 countries
• Sites: N/A

Brief Summary

AMSA nerve block injection is targeted anterior superior alveolar nerve and middle superior alveolar nerve branches of infraorbital nerve through nutrient canals. Therefore, central to second premolar teeth of one quadrant can be anesthetized. The aim of the present study was to evaluate the efficacy of AMSA nerve block injection at an anterior and a posterior positions compared to commonly administrated site.

Conditions

Anesthesia; Functional

Keywords

anterior middle superior alveolar nerve; electric pulp tester; local anesthesia

Outcome Measures

Primary Outcomes (1)

• Pulpal anesthesia of central incisor to second premolar by electric pulp tester (EPT)

  Each teeth were evaluated by electric pulp tester immediately after injection to 60 minutes every six minutes. Having no reaction to the EPT was the criterion of considering a tooth has been anaesthetized. Anesthesia was considered successful if no reaction to the maximum output for two consecutive tests.

  After each injection (base line) to 60 minutes
