perm. mand 1st molar
primary max 2nd molar
primary mand 2nd molar
it is shorter than 1st molar cervico occlusally and narrower mesiodistally
Max 2nd molar

trapezoid
buccal roots are the same length more nearly parallel and are inclined distally
Max 2nd molar
heart shaped occlusal outline
Max 3rd molar
crowns are roughly quadrilateral wider mesiodistally than bucolingually
Mandibular teeth molars
6th cusp located between the 2 lingual cusp
tuberculum intermedium
