Abstract
The"apicaI foram--en may make its exit on the mesial, distal, labial or lingual side of a root slightly short of the root apex rather than at the root apex itself.
The author collected 43 upper first molars and 84 lower first ,´molars as a samples. Apical foramens were carefully checked and examined these location on each tip. (table 1)
1. About .335yo to 495yo of upper cases were found on extreme tip of roots and the remaining cases were on the distal side or menial side.
2. Except distal simple canal of lower molars, approximately 40% to 50% were located
on the very tip´of the root. The remaining cases were on distal or mesial surface..
3. On lower distal simple canal, about 51% of cases made its exit on distal side. The
remaining cases located on the tip end or mesial side.
