[Paresthesia: incidence following the extraction of 455 mandibular impacted third molars]

The incidence of paresthesia following the extraction of 455 mandibular impacted wisdom teeth is evaluated. No permanent paresthesia to the third branch of the trigeminal nerve is noted and no lingual paresthesia. A temporary dyesthesia of the inferior dental nerve is noted for three patients, with a complete return of integrity after six weeks. We have noted an incidence of temporary paresthesia of 3/455 (0.66 per cent) per tooth.
