Comparison of anesthetic efficacy of intraosseous injection
This review focused on comparing the anesthetic efficacy of intraosseous injection and conventional inferior alveolar nerve block in mandibular third molar surgery.

Three electronic databases were accessed to identify randomized controlled trials comparing intraosseous injection with conventional inferior alveolar nerve block in mandibular third molar surgery. The outcome measures included the onset of anesthesia, the success of the anesthetic technique, pain during injection of anesthesia, pain during surgery, and duration of anesthesia. Four studies met the inclusion criteria and consisted of 242 mandibular third molars surgeries.

- No significant differences were found between the anesthetic techniques in terms of onset of anesthesia, the success of the anesthetic technique, pain during injection of anesthesia, and pain during surgery.

- However, the intraosseous technique revealed a significantly shorter duration of anesthesia than the inferior alveolar nerve block.

Despite having similar anesthetic efficacy as the conventional inferior alveolar nerve block, the intraosseous injection has an added benefit of early recovery of sensation due to its shorter duration of anesthesia.
