Study Notes
Primary Dentition Tooth Morphology
- Task 1: Research the differences between primary and permanent dentitions. Create a table or spider diagram.
- Task 2: Complete the Chronology table, List 3-5 identifying features, list the number of cusps (if any), roots, and pulp horns for each tooth, and record the dental notation using Palmer and FDI (both right and left). Use provided resources (website and book). Add pictures to document as needed.
Maxillary Central Primary Incisor
- Chronology:
- Initial calcification: 3-4 months in utero
- Crown completion: 4 months
- Eruption: 7.5 months
- Root completion: 1.5 years
- Notation (Palmer/FDI): URA, ULA/ 51, 61
- Identifying features:
- Rounded disto-incisal angle, sharp mesio-incisal angle
- Similar crown shape to permanent incisor but plumper and more rounded
- Large palatal cingulum, pronounced bulge on labial surface
- Root distal tilt, labially on axis (allows for permanent tooth to develop)
- Mesial and distal cervico-incisal dimensions similar
- Number of cusps: 0
- Number of pulp horns: 2 (mesial and distal)
- Number of roots: 1
Maxillary Lateral Primary Incisor
