Anatomical study reveals high frequencies of four canals and extra roots in Taiwanese mandibular molars, highlighting significant population-specific dental variations.

Key Points

To investigate the root form and canal morphology of mandibular first molar teeth in a Taiwan Chinese population using standardized classification criteria.
Evaluated 183 extracted mandibular first molars rendered transparent through decalcification and clearing techniques.
Examined specimens under a dissecting microscope to document root numbers, canal counts, and canal configurations according to Vertucci's classification.
Four root canals were observed in 46% of molars, and 20% possessed an extra distolingual root.
Mesial roots presented two canals in 97% of specimens (46% Vertucci type 4 and 23% type 2) and three canals (Vertucci type 8) in 6%, with 68% exhibiting two separate apical foramina.
Distal roots exhibited two canals in 46% of teeth and single canals (Vertucci type 1) in 54%, with two separate apical foramina occurring in 33% of two-canaled distal roots.
