Introduction: Anterior Middle
Superior Anesthesia (AMSA) is considered a conductive technique for the
first five maxillary teeth (from central incisors to the second
premolar). This alternative anesthesia is considered a supplementary
technique targeting the subneural dental plexus located near the root
apices of the premolars.
The study aimed to determine whether AMSA anesthesia technique
can serve as a primary and independent method for extracting of the
first five upper jaw teeth (incisors, canines, and premolars).
Materials and methods: The study included 24 healthy patients
allocated in the group I (received 4% articaine with adrenaline) and the
group II (received lidocaine with adrenaline) . The patients had avital
maxillary teeth (from incisors to premolars). AMSA technique was used as
primary anesthesia for extraction. The monitored anesthesia parameters
included: pain perception during the application of anesthesia and the
surgical procedure, overall success of anesthesia, onset time, and
duration of anesthesia and post extraction complications.
Results: The duration of anesthesia was 52±17,10 min in the first
group, while it was 40,25±7,629 min (p=0,044).in the second The level of
pain during the extraction was 3,42± 1,73in the first group, while it
was 5,25±2,41 in the second, with statistically significant difference
between groups (p=0,046). The need for additional anesthesia was 2
(16,66%), in the first and 5 (41,66%). in the second group.
Conclusion: The AMSA technique has demonstrated high efficacy for
simple extractions when articaine is used; it shows less anesthetic
efficacy when lidocaine is used. The AMSA anesthesia technique with
articaine may be considered a primary local anesthesia technique for the
extraction of the first five maxillary teeth when they are not vital.
