title: Is permanent maxillary tooth removal without palatal injection possible?
abstract: OBJECTIVE
  The aim of the present study was to demonstrate if articaine HCl could provide palatal anesthesia in maxillary tooth removal without the need for a second palatal injection.
  
  
  METHODS
  Of 53 patients, 23 had bilateral and 30 had unilateral extractions. In the study group 2 mL of 4% articaine/HCl with 1:100,000 epinephrine was injected into the buccal vestibule of the tooth. After 5 min the extraction was performed. 27 subjects were controls and subjected to the same protocol with palatal injection. All patients completed a Faces Pain Scale (FPS) and a 100-mm Visual Analogue Scale (VAS) after extraction.
  
  
  RESULTS
  According to VAS and FPS scores, when permanent maxillary tooth removal with palatal injection (97.5%) and without palatal injection (96.8%) were compared the difference was not statistically significant (P > .05) [corrected].
  
  
  CONCLUSIONS
  Permanent removal of maxillary teeth without palatal injection is possible by depositing 2 mL articaine/HCl to the buccal vestibule of the tooth.
