%X <B>BACKGROUND: </B>The achievement of successful local anesthesia is a continual challenge in dentistry. Adjunctive local anesthetic techniques and their armamentaria, such as intraosseous injection (the Stabident system and the X-tip system) have been proposed to be advantageous in cases where the conventional local anesthetic techniques have failed.<BR><B>OBJECTIVE: </B>A clinical study was undertaken using intraosseous injection system by name X-tip to evaluate its effectiveness in cases where inferior alveolar nerve block has failed to provide pulpal anesthesia.<BR><B>METHODS: </B>Sixty adult patients selected were to undergo endodontic treatment for a mandibular molar tooth. Inferior alveolar nerve block was given using 4% articaine with 1:100,000 epinephrine. Twenty-four patients (40%) had pain even after administration of IAN block; intraosseous injection was administered using 4% articaine containing 1:100,000 epinephrine, using the X-tip system. The success of X-tip intraosseous injection was defined as none or mild pain (Heft-Parker visual analog scale ratings ≤ 54 mm) on endodontic access or initial instrumentation.<BR><B>RESULTS: </B>Intraosseous injection technique was successful in 21 out of 24 patients (87.5%), except three patients who had pain even after supplemental X-tip injection.<BR><B>CONCLUSIONS: </B>Within the limits of this study, we can conclude that supplemental intraosseous injection using 4% articaine with 1:100,000 epinephrine has a statistically significant influence in achieving pulpal anesthesia in patients with irreversible pulpitis.
