Abstract

In dentistry tooth extraction is routine minor oral surgical procedure. But patients have fear of painful injection for local anaesthesia. For maxillary tooth need to apply buccal and palatal prick for local anaesthesia. Out of this palatal injection is very painful. The aim of this prospective, randomized study is to demonstrate whether 4% articaine hydrochloride administered alone as a single buccal infiltration in maxillary premolar tooth removal, can provide favourable palatal anesthesia as compared to buccal and palatal injection of 2% lidocaine.
Material and Method: Single blinded study was conducted on 50 patients, who required bilateral maxillary premolar tooth extraction for their orthodontic treatment. Extractions were done on single sitting only. Subject received 2% lidocaine with 1:100000 adrenaline on control side (left side) and 4% articaine with 1:100000 adrenaline on experiment side (Right side). Noting the duration for onset of action of the local anesthetic Following extraction all the patients were asked to score the pain experienced during extraction on Faces Pain Scale (FPS) and a 100mm Visual Analogue Scale (VAS).
Result: According to the VAS and FPS scores, the pain on extraction between buccal infiltration of articaine and the routine buccal and palatal infiltration of lignocaine was statistically significant.
Conclusions: The removal of permanent maxillary teeth without palatal injection is possible by depositing 4% articaine hydrochloride to the buccal vestibule of the tooth. Although the technique described here by us can make clinical practice simpler and more comfortable for patients.
