ABSTRACT

Background: The five nerves must be anaesthetized before performing open flap debridement on the maxillary quadrants. We intended to investigate the efficacy of a single injection as the Anterior Middle Superior Alveolar (AMSA) nerve block technique rather than multiple injections. Methods: For this study, 35 male and female subjects aged 18 to 50 years were recruited. For the maxillary periodontal surgeries, all participants received an AMSA block. Anaesthesia efficacy and effectiveness were evaluated and presented as means averages. The subjective and objective signs of anaesthesia efficacy were satisfactory. During the entire procedure, 86.7% experienced no pain and 13.33% experienced pain near the end of surgery that too minimal scoring 2 on the VAS.. Pain was reported in 13.3% of the cases in the anterior teeth buccally. Repeat LA (Buccal infiltration) was given in all these cases. Conclusions: AMSA technique in single injection anaesthetizes larger area in maxilla, both buccal and palatal without collateral involvement of the adjacent lip, nose & eyelids. The AMSA injection can be used as an effective technique to anaesthetize teeth distal to the first molar up to the last standing molar in maxillary periodontal open flap debridement procedures.
