Initiation
Time in prenatal development when initiation of tooth development occurs
When is 6-7 weeks
Developmental process ectoderm & ectomesenchyme under go extensively at the beginning of the 8th week of prenatal development.
What is proliferation?
Location of succedaneous tooth primordium
What is lingual?
Purpose of OEE
What is protective & nutritional layer of enamel organ?
Developmental disturbance that occurs when additional dental placodes are present
What is supernumerary teeth?
Connects developing tooth bud to oral epithelium
What is dental lamina?
Weeks that proliferation, differentiation, and PRIMARILY morphogenesis occur
Results in crown surface pattern
enamel organ invaginates dental papilla
What is dens in dente?
oral epithelium derived from
What is outer part of the ectoderm?
Number of dental placodes on each arch during development of the primary dentition
What is 10?
Developmental process that forms cementum, PDL, & alveolar processes
What is dental sac?
Differentiates into enamel matrix forming ameloblasts
IEE
Stage in tooth development resulting in microdontia or macrodontia
What is bud stage?
Plate of thickened epithelium with underlying NCCs that originates in dental lamina.
What is dental placode?
Combination of bud of dental lamina & surrounding ectomesenchyme
What is tooth germ?
Epithelial structure responsible for determining the future shape of the tooth's crown
What is enamel knot?
Cells resulting from extensive differentiation
What are Stellate Reticulum, Stratum intermedium, IEE, OEE
What is concrescence?
A layer of cells that signal ectomesenchyme to initiate odontogenesis
What is Ectoderm?
Structural changes that occur in epithelial & connective tissues
What is none?
Basement membrane separates
What are enamel organ & dental sac, dental papilla?
Outer cells of dental papilla differentiates into
What is pitting, intrinsic color changes, changes in enamel thickness?
