I am still a predent but this is my guess:

If you bisect each root of both arches of the permanent dentition by its root axis line I think you'll see the following angulations of the root within the alveolar bone of the arch:

maxillary central incisors: very straight & vertical (compared to others)
(In general, anteriors are more vertically situated in the alveolar bone.)

mandibular molars are lingually tilted (usually 3rd mandibular molar is more titled than others because not much space in the back)

P.S. I've never had a dental morphology course. I hope I'm right :)

Hey
The premolars have the most vertical inclination...are the straightest teeth followed by the canines.......

Actually, the maxillary central incisors have the greatest axial inclination/tilt in the entire maxillary arch. You're right about the mandibular molars, though.

Shlo is right about the premolars - they've got the most vertical axial inclination. That's what the decks say, at least!

Thanks :) My mistake: My guess was based on root axis lines & alveolar bone. Oh well, hopefully some day I'll learn these things :)
