Abstract
The study aims to evaluate the anesthetic effectiveness of the Anterior and Middle Superior Alveolar (AMSA) injection administered through a computer-controlled local anesthetic delivery system (CCLAD), and compare it with the traditional buccal and palatal injections used to anesthetize maxillary primary molars.
The sample included 80 primary maxillary molars, divided into 2 equal groups: Pulpotomy and extraction groups. Each group was divided equally into 4 subgroups: A. First molars anesthetized with the traditional technique, B. first molars anesthetized with the CCLAD, C. second molars anesthetized with the traditional technique, and D. second molars anesthetized with the CCLAD. The evaluation was done single blind using SEM scale.
The AMSA injection with the CCLAD was found to be effective in anesthetizing maxillary primary molars in pulpotomy and extraction procedures. There was no significant difference between the two anesthetic techniques except in the step of gingival retraction buccally in, which the traditional injections were more effective than the CCLAD during extractions. No significant difference was found between first and second primary molars in the effectiveness of both techniques.
The AMSA injection using CCLAD was found to be effective in children.
