[Lesions of the inferior alveolar nerve during extraction of the wisdom teeth. Consequences--prevention].

Neurological consequences of extractions of the third inferior molar can be severe. Progress in imaging techniques has made it possible to identify molars << at risk >>. Extraction by wear without removal of the apex is proposed as a means of avoiding damage to the alveolar nerve. If no surgical prophylaxy is used the risk is major sequellae: painful anaesthesia of the area involved. There is no really effective treatment for such sequellae, creating persistent psychological problems throughout life.
