    a. Maxillary 2nd molar?

Answer 16

16. In line with the cusps

Question 17

17. What is normally found on the lingual surface of the palatal root of a maxillary 1st molar that is not found on the 2nd or 3rd molars?

Answer 17

17. In line with cusp tips

Question 18

18. The presences or absence of which cusp determines whether a maxillary 2nd or 3rd molar is heart-shaped or rhomboidal?

Answer 18

18. DL cusp
