VM Tooth Eruption Flashcards
what stage is this tooth germ?
cap stage
dental papilla
dental lamina
enamel organ
what stage of tooth development is this tooth germ?
bud stage
vestibular lamina
dental papilla
what stage of tooth development is this tooth germ?
cap stage
infraorbital nerve
inferior nasal concha
palatal process of developing maxillary bone
alveolus of developing maxillary bone
enamel organ
dental follicle
dental papilla
successional lamina
dental lamina
vestibular lamina
inner enamel epithelium
stratum intermedium
successional lamina
stellate reticulum
outer enamel epithelium
what stage of tooth development is this tooth germ?
crown stage
hard tissue formation
dental lamina
cell rests and nests
successional dental lamina
inner enamel epithelium
stellate reticulum
outer enamel epithelium
oral epithelium
collagen = blue
enamel organ = epithelium
dental papilla
dental follicle
alveolar bone
what are cell rests and nests?
residual epithelium have the potential to develop into cysts
stratum intermedium
ameloblasts
stellate reticulum
alveolar bone
dental papilla
cervical loop
dental follicle
enamel organ
oral epithelium
successional dental lamina
alveolar bone
what gives the prismatic structure of enamel?
Tomes process and direction of retreat of ameloblasts
initial predentine formation
maturing inner enamel epithelium
mineralised dentine
fusion of calcospherites -> fuse globularly
Initial enamel formation
whats happening here
Outer epithelium folds around capillary beds
New blood supply for ameloblasts
Stellate reticulum thickness decreases
Space between enamel and dentine due to the way the section is prepared as it is a calcified structure, so it is taken off.
what is the order of primary tooth development?
abdce
alveolar bone
successional dental lamina
