Asociación del canal mandibular con las terceras molares evaluadas mediante radiografía panorámica y tomografía computarizada de haz cónico en pacientes de 18 a 85 años del instituto de diagnóstico maxilofacial

Abstract

Objective: To determine the association of mandibular canal with the third molars evaluated by panoramic radiography and cone beam computed tomography in patients aged 18 to 85 years. Materials and Methods: A study was observational, descriptive, cross-sectional and retrospective. A total of 301 lower third molars of patients attended at the Instituto de Diagnóstico Maxilofacial were used. Results: Assessing the association of mandibular canal with the third molars in a panoramic radiography was found more frequently 125 molars that were in no contact with the mandibular canal (41.5%). On the other hand, it was found high frequency of molars that were inferior to the mandibular canal (69.77%). Likewise, it was showed that exist statistically significant association in determining the association of the mandibular canal with the third molars in a panoramic radiography and computed tomography (p=0.000). Conclusion: There is association in assessing the mandibular canal with the third molars by panoramic radiography and cone beam computed tomography. However, those who present contact of canal with third molars should be considered patients with high risk of nerve injury.
