Study Notes
Importance of Primary Dentition
- Primary teeth play a crucial role in space maintenance, eating and chewing, speech development, aesthetics, and oral hygiene habits.
- Premature loss of a primary tooth can lead to the drifting of adjacent teeth, delayed eruption of the permanent successor, ectopic eruption of the permanent tooth, and malocclusion.
- Retention of primary teeth can occur if there is no permanent predecessor present.
- Trauma to primary teeth can cause developmental disorders in permanent successors, with the severity of the damage increasing with the child's age at the time of the trauma.
- Avulsion, the complete displacement of a tooth, can lead to root resorption, enamel hypoplasia, root angulation, and odontoma-like malformations in permanent teeth.
Differences Between Primary and Permanent Dentition
- There are fewer primary teeth than permanent, with primary teeth being smaller and whiter.
- Primary teeth lack premolars and exfoliate to be replaced by permanent teeth between 6 to 13 years old.
- Permanent teeth have mammelons, present on the incisal edges, absent in primary teeth.
- Primary teeth have thinner enamel, larger pulp chambers, and thicker dentine compared to permanent teeth.
Eruption Dates
- The first primary tooth to erupt is the lower central incisor (A) at 6 months.
- The last primary tooth to erupt is the lower second molar (E) at 2-2.5 years.
Teething
- Symptoms of teething include flushed cheeks, red and sore gums, increased drooling, biting and chewing on objects, irritability, and rubbing the ear.
- It's important to note that there is no evidence to support claims that teething causes diarrhea or other unrelated symptoms.
Conditions Affecting Primary Dentition
- Hypoplasia of enamel can occur due to a lack of oxygen, abnormal enamel formation, or amelogenesis imperfecta, all of which can increase the risk of caries due to pits, fissures, and exposed dentine.
- Developmental enamel defects can present as enamel hypoplasia or opacities, caused by damage to the developing enamel. These defects increase the risk of early childhood caries and toothwear.
