Study Notes
Primary Teeth Characteristics
- Primary teeth exhibit wider mesiodistal dimensions relative to their crown length.
- Anterior primary teeth feature longer and narrower roots compared to their crowns.
- Primary molar roots are longer, more slender, and flare out beyond the projected outline of the crowns.
Crown and Root Structure
- The cervical portions of primary molar crowns and roots are slender mesiodistally.
- Primary teeth have less pigmentation, resulting in a whiter appearance compared to permanent teeth.
True or False Statements
- True: The cervical ridges of enamel on anterior teeth are more prominent in primary teeth.
- True: The buccal and lingual surfaces of primary molars are flatter at the cervical curvatures than those of permanent molars, which results in narrower occlusal surfaces.
- True: The cervical ridges buccally on primary molars are significantly more pronounced than on permanent molars.
- False: The roots of primary teeth are generally longer and narrower, contrary to being shorter and wider.
- True: The roots of primary molars are indeed longer, slender, and extend beyond the crown outlines.
