"Bud stage" Tooth formation begins; follows a definite pattern and takes place at a different time for each tooth
Also called proliferation; cells of developing tooth grow and increase in number; developing tooth change in size and proportion; tooth bud changes into hollowed caplike shape
Permanent teeth that replace primary teeth; develop from tooth buds deep in dental lamina
Enamel organ (cap stage)
Originates from ectoderm layer; tooth bud enlarges to become enamel organ which eventually forms enamel; Shallow indented area appears along lower margin of enamel giving the shape of a cap
Originates from mesoderm; cells of connective tissue proliferate and eventually form dental pulp and dentin
Mesenchyme froms dense band of connective tissue which surrounds enamel organ and dental papilla; sac becomes periodontal ligament and cementum
Differnt tissues of tooth form and shape of tooth is established; as cells increase in number, they layer into shape of a bell
Structural outline formed earlier is hardened by deposits of calciun and other salts; enamel is built layer by layer
Enamel is built in layers
starts at DEJ (dentoenamel junction) and progresses outward; starts at top of crown and progresses downward over sides
movement of tooth into its functional position; takes place in chronological order; Tissue in area disintegrates causing inflammation and tenderness
