Tooth bud consists of...

Dental organ, dental papilla, and dental sac

Odontoblasts

Dentin forming cells

Primary dentin

Dentin in newly formed tooth

Calcification

Deposit of lime salts

Cementoclasts

Destroy tooth cementum

Midline

Determines right and left sides

Third Stage of Development

Differentiation

Granuloma

Growth or tumor found in root area

Enamel

Hard tooth covering

Fibers

Help the dentin to nourish and register sensation

Marginal

Helps to form the sides of the gingival crevice

Differentiation occurs in two ways...

Histodifferentiation, morphodifferentiation

First Stage of Development

Initiation

Gingiva

Mucous tissue surrounding teeth that protects teeth and underlying tissues

Papillary

Occupies the interproximal spaces

Irregular secondary dentin

Occurs as protection from irritation, decay, trauma, attrition

Regular secondary dentin

Occurs during regular development and maturing of tooth
