Study Notes
Tooth Calcification and Eruption
- Mandibular incisors begin calcification before birth.
Primary Tooth Eruption Sequence
- Mandibular central incisors erupt first, followed by maxillary central incisors, then mandibular lateral incisors, followed by maxillary lateral incisors, then first mandibular molars, then first maxillary molars, then mandibular canines, followed by maxillary canines, then second mandibular molars, and lastly second maxillary molars.
Tooth Eruption and Root Formation
- First permanent molars, central incisors, and lateral incisors appear in the oral cavity when the crown and cervical 1/3 to 1/2 of the root are completed.
- The root formation of deciduous teeth occurs after their eruption.
Permanent Tooth Eruption and Calcification
- Permanent premolars begin calcification at age 1.5–2 years.
- First permanent molars begin erupting at age 6, and calcification begins at birth.
- Second molars erupt at age 12.
Tooth Identification and Terminology
- Universal Numbering System is commonly used throughout a dental career.
Specific Tooth Eruption and Calcification Data
- Permanent first premolar eruption date is 7 months after birth when calcification begins at 4.5 months in utero.
- Permanent tooth crown formation is 33% complete at birth when calcification begins at 5 months in utero and the eruption date is 16 months after birth.
- First permanent molar calcification begins at birth when the eruption date is 6 months after birth.
Mandibular Primary Tooth Eruption Sequence
- Mandibular central incisors, followed by mandibular lateral incisors, then first mandibular molars, then mandibular canines, and finally second mandibular molars.
Eruption Timing Based on Root Formation
- Deciduous teeth start to erupt when only one-third of the root is formed.
Permanent Canine Function
- Permanent canines contribute to tearing, puncturing, and holding food in the oral cavity during chewing.
