Study of foramen openings and their concurrence with root apexes

Resumo

The present study is aimed at evaluating the anatomic concurrence
between foramen openings and root apexes of 247 upper and lower
permanent human molar canals, the distance between these structures,
the instrument that best fits into the root canal, as well as the direction
of foramen deviation. Sixty-four of the canals were partially
impenetrable and were discarded. The findings showed that 39.9% of
the root canals studied had their apical foramen concurrent with their
root apexes and 60.1% did not. Clinicians must be made aware of this
important anatomical detail, which could be indispensable for
successful endodontic treatment.
