Homework Answers
1.A cusp is a pointed ,elevated feature in teeth(incisal eminence) .Premolars help in maintenance of vertical dimension of face and support mastication. Premolars have 2-3 cusps ( buccal and lingual). 2cusps means 1 buccal and 1 lingual cusp. 3 cusps means 1 buccal and 2 lingual cusp.premolars also known as bicuspids.There are totally 8 Premolars in the mouth .
2.Y- shaped central groove and linear lingual groove are the two developmental groove patterns that are possible in three cusps type.( 1 large buccal and two small lingual cusp is three cusp type)
