Study Overview
Brief Summary
Linear relation between premolars and molars root apex and superior border of inferior alveolar canal
Detailed Description
The aim of the study is to assess the linear position between the roots of mandibular premolars and molars and the superior border of inferior alveolar canal.
Population: Adults, male and female from Egyptian population Outcome Variable: Linear measurement of the distance between root apices of mandibular premolars and molars to the superior border of IAN.
