[Feasibility of permanent maxillary tooth removal using articaine anesthesia without palatal injection].
OBJECTIVE
This study was to test the feasibility of permanent maxillary tooth removal using articaine without a second palatal injection.


METHODS
Of 104 patients, 38 patients had bilateral extraction and 66 patients had unilateral extraction of maxillary tooth. In the test group, 1.7 mL articaine with 1:100000 epinephrine was injected into the buccal vestibule of the tooth and the tooth were extracted after 5 minutes. In the control group, the patients were subjected to both palatal injection with 2% lidocaine hydrochloride and buccal injection with articaine. All patients completed visual analog scales (VAS) after extraction.


RESULTS
The achievement ratio of permanent maxillary tooth anesthesia of test group was 96.2%. The achievement ratio of permanent maxillary tooth anesthesia of control group was 97.1%. There was no statistical significance between achievement ratio of test group and control group(P > 0.05).


CONCLUSIONS
Permanent maxillary tooth removal without palatal injection is possible by articaine injection to the buccal vestibule of the tooth.
