Microsurgical Repair of Inferior Alveolar Nerve Injuries Associated With Endodontic Treatment: Results on Sensory Function and Relief of Pain

Surgical outcomes of the surgical techniques following management of iatrogenic trigeminal nerve injuries: A systematic review

Legal Liability of a Dentist: Inferior Alveolar Nerve Damage After Calcium Hydroxide Extrusion

“…The cause if initial delay to appropriate referral relied on the dentist who performed the endodontic treatment. 3 There is a range of endodontic malpractice, generally classified as preoperative, intraoperative, and postoperative. The majority of endodontic malpractice cases occur during the intraoperative phase, including Ca(OH) 2 extrusion through the root apex.…”

“…Should a patient exhibit neuropathic indications in the first 24 to 58 hours after IAN injury due to endodontic treatment, an immediate micro- surgical consultation is recommended. The cause if initial delay to appropriate referral relied on the dentist who performed the endodontic treatment 3 …”

“…2 Thus, IAN injury caused by Ca(OH) 2 extrusion can cause serious debilitating and deleterious effects on patients' quality of life, where it can disrupt everyday orofacial activities. 3 In dental medicine, malpractice is an act of dental professional failure to follow the required standards of practice that result in injury or damage to a patient. Endodontic-related cases involve the most frequently filed malpractice claims among dentistry fields.…”
