Although conventional (Halsted) inferior alveolar nerve block is the most applied nerve block in Dentistry, it is still the most frustrating with high failure rates up to13% or even higher due to inconsistent intraoral landmarks. So, the current study aims at comparing a novel technique for the inferior alveolar nerve block (IANB) depending on extraoral landmarks with the conventional technique. The study group patients received IANB employing the novel technique. The novel technique depended entirely on extraoral consistent landmarks which were the base of the columella, the outer canthus of the right and the left eye, and the upper lip. In the control group, the conventional technique was applied. The success rate and the onset, the duration, and the depth of anaesthesia were assessed. Complications were recorded. While the novel technique achieved higher success rate (98.68%) than the conventional technique (88.16%), the differences with regards with all other parameters to assess the local anaesthesia were statistically insignificant. The novel technique provides the clinicians with a new tool that might be a reliable substitute for the conventional technique since the former depends entirely on extraoral consistent landmarks, which also might account for its simplicity, accuracy, and high success rate.
