for 400 patients over 65 years who had a third retained mandibular molar and had a panoramic radiograph and a mandibular CBCT with selected one, or several, radiological signs of relationship between the third molar and the mandibular canal. Then the relationship between these signs and different situations between the alveolar nerve and the lower third molar was categorized with the classification of Tanaka et al.. Results: A total of 565 third molars were analyzed showing a 52.2% one

The associations signs determines the loss of cortical alveolar canal (p <0.05). When darkening roots appear, the vestibular nerve is located at 42.9% (p <0.05) increase the risk nervous due to the surgical approach of the third molar. Conclusions: The risk of nerve injury in elderly patients is higher in cases where darkening of roots and more than a sign of relationship are present.
