Abstract

Aims: A clinical evaluation on a recently introduced technique of anesthesia for maxillary teeth namelythe Anterior and Middle Superior alveolar nerve block compared with the conventional infiltrationtechnique for extraction of upper anterior and premolar teeth. Materials and methods: In the first partof the study, testing of pulpal anesthesia were performed after administering this technique for teethfrom upper central incisor to upper second premolar. The sample chosen for the second part of thestudy included 60 subjects of different ages and genders. The patients were divided randomly into twogroups: control group to whom the conventional supraperiosteal injection technique was administeredand the trial group to whom the anterior and middle superior alveolar nerve block technique was administered.In both groups, extraction was carried out. Results: The result of this study indicated thesuccess of achieving pulpal anesthesia after AMSA injection for teeth from the upper canine to the uppersecond premolar with no significant difference noticed between AMSA and control group in regardingto pain score levels after extraction of these teeth. Conclusions: This new technique could beused as a good alternative and or supplementary to the infiltration technique for anesthetizing maxillaryanterior and premolar teeth using a conventional dental syringe.

Highlights

Local anesthesia for maxillary teeth is mainly achieved by the supraperiosteal infiltration technique
The provision of many dental treatments depends upon achieving excellent local anesthesia
The success rate for AMSA nerve block technique reported in this study was near to 76% compared to 86% for the supraperiosteal infiltration

Summary

Introduction

Local anesthesia for maxillary teeth is mainly achieved by the supraperiosteal infiltration technique. A new technique for blocking the anterior and middle superior alveolar nerve through a palatal injection site has been introduced. This technique was first developed in 1998 by Friedman and Hochman as a new concept to anesthetize maxillary teeth using a computer controlled local anesthetic delivery system (CCLAD). The technique is most accomplished when performed with CCLAD which provides a steady deposition of anesthetic solution. This injection has been successful using a standard aspirating dental syringe (1)
