    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.
