Abstract

Aims: identify morphologic characteristics of first upper molar root canal in group of people lived in Hanoi city and nearby. Results: CBCT of 334 patients were used. Most first upper molar have 3 separate roots (99,55%);  additional canals were found in 35,78% of the mesiobuccal (MB), no difference between the right and left side. The distal and medial roots have only one canal from the canal entrance to the apex. The global prevalence of  C-shaped canal is 2,99%, of which the B1-type accounts for 1,04% and C-type accounts for 1,2%. No difference between male and female,
