Deciduous Teeth Flashcards
How does the enamel of deciduous teeth compare with permanent teeth?
Whiter
Softer
How do the crowns of deciduous teeth compare with permanent teeth?
More rounded cervical margin
More bulbous
Sharper/more pointed cusp tips
Anterior teeth are smaller but molars are larger than premolar successors
How do the roots of deciduous teeth compare with permanent teeth?
Longer and more slender compared to the crown
Resorption occurs in deciduous
More widely splayed molar roots
How do the pulp chambers of deciduous teeth compare with permanent teeth?
Larger in deciduous
How do the anterior deciduous teeth compare with anterior permanent teeth?
Smaller, more rounded versions
Lower incisors are not as chisel-shaped
(Often worn down very quickly)
What are the differences between the maxillary and mandibular canines?
Maxillary is broader with a larger cingulum
Distal slope of maxillary is SHORTER than mesial slope (only exception)
Describe the maxillary second molar
Smaller version of permanent maxillary first molar
Rhomboidal with 4 cusps
Largest cusp is mesial-palatal
Oblique ridge from mesial-palatal to distal-buccal with H-shaped fissure pattern
3 widely-splayed roots
Describe the mandibular second molar
Smaller version of permanent mandibular first molar
Oblong with 5 cusps
2 widely-splayed roots
Describe the maxillary first molar
Ridge-like buccal and palatal cusps with fissure between
Buccal cusp longer than palatal
Mesial-palatal corner is obtuse
Tubercle of Zuckerkandl at cervical margin of mesial-buccal corner
3 widely-splayed roots
Describe the mandibular first molar
Oblong with obtuse mesial-lingual corner
4 cusps: largest is mesial-lingual
Mesial cusps are larger and have an oblique ridge between them
Small anterior fossa and larger posterior fossa
Tubercle of Zuckerkandl on cervical margin of mesial-buccal corner
2 widely-splayed roots
