More model informationo Very similar to first premolars, with very similar sizes
o Less common and less prominent developmental grooves, leading to a less prominent buccal ridge and line angles and overall more rounded anatomy.
o The lingual cusp is proportionally larger and almost the same size as the buccal cusp
o There is no mesial marginal groove or mesial concavity
o 90% of these teeth present only one root
o The lingual cusp apex is also located to the mesial
o The buccal cusp ridge is more rounded than observed in the first premolar
