Clinical Crown Portion of the tooth that is visible in the oral cavity.
Dentin Hard portion of the root that surrounds the pulp and is covered by enamel on the crown and by cementum on the root.
Exfoliation The normal process of shedding the primary teeth.
Mandibular The "Lower Jaw"
Periodontium Structures that surround, support, and are attached to the teeth.
Primary Cementum Cementum that covers the root of the tooth and is formed outward from the cementodentinal junction for the full length of the root.
Primary Dentin Dentin that forms before eruption and that makes up the bulk of the tooth.
Pulp Chamber The space occupied by pulp.
Tooth Buds Enlargements produced by the formation of dental lamina.
Facial Development 5th and 8 weeks of development
Tooth Development 5-6 weeks of development
Tooth Movement Remodeling
Calcification Process by which the structural outline formed during the growth stage is hardened by the deposit of calcium and other mineral salts.
Alveolar Crest Highest point of the alveolar ridge.
Alveolar Socket Cavity within the alveolar process that surrounds the root of a tooth.
Anatomic Crown Portion of the tooth that is covered with enamel.
Apex Tapered end of each root tip.
Shedding Exfoliation
Enamel Hardest material in the body.
Articular Eminence Raised portion of the temporal bone just anterior to the glenoid fossa.
Articular Space Space between the capsular ligament and between the surfaces of the glenoid fossa and the condyle.
Condyloid Process The posterior process of each ramus

Embrasure Triangular space near the gingiva between the proximal surfaces of two adjoining teeth.
Trifurcation Area at which three roots divide.
Bifurcation Area at which two roots divide.
