Final answer:
The facial surfaces of premolars develop from four lobes.
Explanation:
The facial surfaces of premolars develop from four lobes.
Teeth in adults are distributed among four quadrants of the mouth, with each quadrant containing eight teeth: two incisors, one canine, two premolars, and three molars. Premolars have two rounded cusps and are used for grinding and mashing food. The development of dental lobes contributes to the formation of these teeth.
For example, the premolars have four lobes, which give rise to the cusps and surfaces of the tooth. Each lobe contributes to the growth and development of specific parts of the tooth structure.
