Radiographic analysis of the proximity of the molar roots to the inferior alveolar nerve
Keywords:radiograph, mandibular nerve
AbstractThe mandibular canal direction, according to the lower border of mandible, is lateralinferior with an anterior superior concavity presenting a close relationship between itself and the apexes of the inferior molars. The aim of this research was to radiographically analyse the relationship of the proximity of molars to the mandibular canal as well as to observe clinically the difficulty of extraction of the inferior third molar according to its position in dental arch. A hundred and fifty panoramic x-rays, from PUCPR Dental Clinic, were analysed by meansuring the distance between the apexes and the roof of mandibular canal with an caliper ruler. Applying the Paired Samples Correlations and the Wilcoxon Signed Ranks tests (p > 0,05) it was constated a significative positive correlation when the roots of molars were analised independently and compared with their contralateral homonymous. It could be conclued, by the researched sampe, that the difficulty of third molars extraction is relied on types of dental inclusion once the tarjet of mandibular canal is simetric bilaterally. UNITERMS: mandibular canal; inferior molars; inferior alveolar nerve; panoramic x-ray
