Aim: The aim of the present clinical trial was toevaluate thee fficacy ofa relatively neweranterior middle superior alveolar (AMSA) local anaesthetic technique for the extraction of anterior maxillary teeth.

Method: Forty subjects with an age range of 18to45 years were selected for the present study. AMSA technique was used for obtaining local anaesthesia of maxillary anterior teeth. 2% ligocaine containing 1:200,000 epinephrine was used for anaesthesia. For each patient, the operator obtained the time of onset of anaesthesia, visual analogue scales for pain after the injection and immediately after extraction. VAS scores of acceptance of the procedure were also recorded postoperatively. Patients Data was analyzed using descriptive statistical methods (frequency, means and standard deviations) using SPSS ver. 16.0 (SPSS Inc.).

Results: The average time of on setin seconds was M=291.46, SD=50.26 and SEM=8.04 in seconds. The pain of injection in VAS score was M=4.02, SD=1 .06 and SEM=0.17. The pain of extraction in VAS score was M=0.56, SD=0.64, SEM=0.10. The patients’ acceptance of the procedure in VAS score was M=2.74, SD=0.91 and SEM=0.14). All the patients accepted the procedure well and did not have any post extraction complications. All were evaluated seven days after the procedure and showed satisfactory healing of the extraction sockets.

Conclusions: The AMSA technique is a useful alternative technique for maxillary anterior teeth extractions. It is a preferable technique for periodontal surgeries and restorative procedures, because it does not anaesthetize the buccal and facial tissues.
