NEMESIS

Impacted and ectopic lower third molars located in the sigmoid notch are very rare in clinical practice. Their etiology remains uncertain, although disturbances in the dental eruption process or consequences of trauma are suspected. Most cases described in the literature present various symptoms and require surgical management. The objective of this work is to conduct a literature review on impacted and ectopic lower third molars in the sigmoid notch region, to present a new clinical case illustrated by cone beam computed tomography (CBCT), and to establish possible management strategies, exploring the indications for surgical intervention according to the available literature.
