Study Notes
- Tooth exfoliation and eruption are key topics
- GDC Learning Outcomes (2015) related to this include: 1.1.5, 1.1.6, 1.2.4, 1.2.5, 1.2.7, 1.7.7, 1.8.3, 8.2, 9.4, 9.6
Aim
- This study aims to understand the sequence and importance of eruption and exfoliation chronology
- It relates to primary dentition and the eruption of secondary dentition
Learning Outcomes
- Understanding the terminology used in eruption and exfoliation sequences isimportan
- Understanding normal vs. abnormal dental development is vital
- Knowing calcification dates for primary and permanent dentition is an important learning outcome
- Knowing the eruption dates for primary and permanent dentition is essential for dental professionals
- Knowing exfoliation dates for primary dentition is needed
Reasons for Learning Eruption/Exfoliation Patterns
- Primary teeth maintain space in the jaw for permanent teeth, which take their place when primary teeth are lost
- Deviations from normal exfoliation and eruption sequences require understanding the typical sequence
- Girls' dentition tends to erupt sooner than boys'
Impact to Permanent Dentitions - Systemic or Local
- Systemic factors may lead to: delayed eruption, non-formation, or Molar-Incisor Hypomineralisation (MIH)
- Genetic factors can influence dental development
- Nutrition plays a key role in tooth formation and eruption
- Metabolic or Endocrine disorders disturb dental development
- Pyrexia, like systemic infections, can impact teeth
- Diseases, such as kidney issues or cancer, can affect dentition
- Certain medications like chemotherapy drugs or phenytoin impact dentition
- Fluorosis can also affect teeth
- Low birth weight or exposure to smoking are additional factors
Impact to Permanent Dentitions - Generalised or Localised
- Local factors also induce delayed eruption, non-formation, or Molar-Incisor Hypomineralisation (MIH)
- Early loss of deciduous teeth has possible effects on permanent dentition
- Impacted or misplaced teeth can result in permanent teeth out of position
- Maxillary 3s and mandibular 8s are frequently impacted
- Missing dentition often involves maxillary 2s and mandibular 8s
- Supernumerary teeth present an over number of teeth
- Trauma, gingival hyperplasia/fibrosis, oral clefts, and eruption cysts can impact permanent dentition

- Crown completion requiring is 9 months
- Eruption at 9 months, with roots taking 2.5-3 years
- First Molar (D)
- Calcifies at 5 months in utero
- 6 months to complete the crown
- Eruption at 6 months, with roots completing growth at 2-2.5 years
- Second Molar (E)
- Calcifies at 6 months in utero
- Requires 10-12 months for crown completion
- Erupts between after 10-12 months, with roots completing in 3 years
