Study Notes
Eruption of Teeth
- The sequence of eruption of permanent teeth in the mandible is: first molars, central incisors, lateral incisors, canines, first premolars, second premolars, and second molars.
- Second molars erupt in permanent dentition at around 12-13 years old.
- Crown completion before eruption in permanent teeth takes around 5-6 years.
- Root formation of deciduous teeth occurs about 1-2 months before eruption.
- Permanent first molars erupt between 6-7 years old.
Tooth Development
- Calcification of primary teeth begins before birth; the tooth type that begins calcification before birth is the primary incisors.
- The sequence of eruption for primary teeth is: lower central incisors, upper central incisors, upper lateral incisors, lower lateral incisors, canines, and first molars.
Tooth Characteristics
- The tooth type associated with 'compensatory curves' is the permanent maxillary first molar.
- The intended learning outcome related to eruption dates and sequence of eruption of primary and permanent teeth is to understand the timeline and order of tooth eruption.
Timeline of Tooth Development
- First permanent molars begin calcification around 3-4 years old.
- Crown completion of permanent teeth occurs about 5-6 years before eruption.
- Root formation of deciduous teeth occurs about 1-2 months before eruption.
