OBJECTIVES To evaluate whether age and gender differences are predictive factors for inferior alveolar nerve position with respect to mandibular first molar roots. STUDY DESIGN Cone-beam computed tomography scans [0.2-mm3 voxel size; n = 200 (100 males, 100 females)] of patients aged 15-65 years showing mandibular first and second molars were included in this study. Patients with pathoses tha...

Long acting local anaesthetics and inferior alveolar nerve block in children can cause loss of sensation and proprioception in a large area supplied by that particular nerve. Similar to the maxilla in mandible also, adequate level of anaesthesia can be achieved in the desired site of treatment by using a short acting local anaesthetic. Early return of normal sensory feedback after using short a...

There are reports on hypoesthesia and anesthesia in taste sensation persisting for several months or even years after dental anesthesia, pulpectomy and tooth extraction. Taste disorders following dental treatments are usually attributed to peripheral injury of taste (the chorda tympani) nerve fibers running with the lingual nerve fibers near the mandibular molars. 2 However, taste impairment in...

The present case report describes a complication involving facial blanching symptoms occurring during inferior alveolar nerve block anesthesia (IANBA). Facial blanching after IANBA can be caused by the injection of an anesthetic into the maxillary artery area, affecting the infraorbital artery.

Efforts to apply augmented reality (AR) technology in the medical field include the introduction of AR techniques into dental practice. The present report introduces a simple method of applying AR during an inferior alveolar nerve block, a procedure commonly performed in dental clinics.

We report a case of a 42-year-old female who was referred to our department for the management of a fractured dental needle following administration of an inferior alveolar nerve block. The fractured needle was successfully removed under general anaesthesia. We also suggest some guidelines for preventing this unfortunate event.
