[New strategies to prevent and control nerve dysfunction after dental extraction].

Nerve dysfunction is a common postoperative complication of dental extractions. In dental extraction, the nerves involved mainly include the inferior alveolar nerve, lingual nerve, buccal nerve, chin nerve and nasopalatine nerve. Nerve dysfunction will seriously affect the patient's quality of life and may lead to medical disputes. This review firstly summarizes the clinical manifestations and pathological mechanisms of post-dental extraction nerve dysfunction, then summarizes its clinical risk factors and preventive strategies, then analyzes the clinical characteristics and physiological mechanisms of natural sensory recovery after dental extraction nerve dysfunction, and finally summarizes the cutting-edge therapeutic tools and research directions in the treatment of post-dental extraction nerve dysfunction in recent years. The aim of this article is to comprehensively review the cutting-edge advances in post-dental extraction nerve dysfunction from clinical to molecular mechanisms, and from pathogenesis to prevention and treatment strategies, and seeks to provide reference for oral surgeons in preventing and responding to the treatment of nerve dysfunction after dental extraction.
