A comparative evaluation of pain and anxiety levels in 2 different anesthesia techniques: locoregional anesthesia using conventional syringe versus intraosseous anesthesia using a computer-controlled system (Quicksleeper).
OBJECTIVE
The aim of this study was to compare anxiety and pain levels during anesthesia and efficacy of Quicksleeper intraosseous (IO) injection system, which delivers computer-controlled IO anesthesia and conventional inferior alveolar nerve block (IANB) in impacted mandibular third molars.


METHODS
Forty subjects with bilateral impacted mandibular third molars randomly received IO injection or conventional IANB at 2 successive appointments. The subjects received 1.8 mL 2% articaine.


RESULTS
IO injection has many advantages, such as enabling painless anesthesia with less soft tissue numbness and quick onset of anesthesia as well as lingual and palatal anesthesia with single needle penetration.


CONCLUSIONS
Although IO injection is a useful technique commonly used during various treatments in dentistry, the duration of injection takes longer than conventional techniques, there is a possibility of obstruction at the needle tip, and, the duration of the anesthetic effect is inadequate for prolonged surgical procedures.
