Study Notes
Tooth Development and Eruption
- Deciduous teeth begin to develop at 7-9 weeks in utero.
- Calcification of deciduous teeth begins at birth, specifically the primary teeth.
Calcification of Permanent Teeth
- Calcification of the first permanent molars begins around birth.
- The crown of the first permanent molar starts to form around 3-4 years old.
Tooth Formation
- The crown of a deciduous tooth is mostly formed at birth, taking around 12-14 weeks to develop.
- The occlusal surface of a permanent tooth starts to form around 2-3 years old.
Tooth Eruption
- The shedding of deciduous teeth begins around 6-12 years old.
- The sequence of eruption of primary teeth is: lower central incisors (6-12 months), upper central incisors (8-12 months), lower lateral incisors (9-16 months), upper lateral incisors (9-13 months), canines (16-22 months), first molars (13-19 months), and second molars (23-28 months).
- The sequence of eruption of permanent teeth is: first molars (6-7 years old), central incisors (7-8 years old), lateral incisors (8-9 years old), canines (11-12 years old), premolars (10-12 years old), second molars (12-13 years old), and third molars (17-21 years old).
- The first, second, and third permanent molars erupt at 6-7 years old, 11-13 years old, and 17-21 years old, respectively.
Tooth Identification Systems
- The Universal Numbering System is used throughout a dentist's career to identify teeth.
- Tooth eruption occurs in three stages: bud stage, cap stage, and bell stage.
This quiz covers the form and function of different types of primary and permanent teeth, including dental terminology, tooth identification systems, eruption dates, and sequence of eruption. It aims to enhance the student's knowledge in dental anatomy and prepare them for their career.
