field of anatomy dedicated to the study of human tooth structures.

arrangement or condition of the teeth.

Greek meaning “different teeth”

two sets of teeth in a lifetime.

Two sets of Teeth

also known as Deciduous Teeth, Primary Teeth, Baby Teeth or Milk Teeth. Begins to form at about 14 weeks in utero. Begins to emerge at the mean age of 6 months and last emerge at a mean age of 28 +- 4 months (3 years old)

also known as Secondary Dentition. To erupt at a mean age of 6 years old. Marks the transition stage.

mixed dentition stage or the Ugly duckling stage

Two types of Permanent Teeth:

replaces the deciduous teeth in the dental arch.

What are the Succedaneous Teeth?

What are the Non-Succedaneous teeth?

appear in the oral cavity by the age of 6 years old

2 Types of Teeth base on location

Front teeth; Central and Lateral Incisors and Canine

back teeth; Premolars and Molars

are the squarish, sharp-edged teeth at the front and middle of the mouth.

to the sides of the incisors are the long, sharp.

These teeth are absent in the primary set.

situated behind the premolars, have points and grooves; Wisdom Teeth.

last teeth to erupt

Stages of Tooth development:

combination of the dentin and cementum formed by Odontoblasts and Cementocytes.

mineralized entity.

Two portions of the tooth:

is the visible portion of the tooth.

is covered by the gingival or the gums.

also known as Cervical Line. “Neck” portion of the tooth.

second layer of the tooth

forming the core respectively

Tooth consists of four types of tissues:

hardest tissue in the human body, covering the crown of the tooth.

a hard yellow substance, makes up most of the tooth/main bulk. Gives the teeth slightly yellowish tint.

covers the root and holds the tooth in place within the jawbone.

the innermost portion of the tooth.

pulp is soft, and it is made of:

Two Parts of Pulp

opening at the apex of a root through which the nerve and blood vessels of the pulps enters and exits.

Dentino-Cemental Junction. Terminal end of a root by which the pulp tissue enters and exits.

Bony process of the jaw which houses the tooth in place in the dental arch.

embedded into the cementum of the adjacent tooth and extends interproximally over the alveolar crest.

extends obliquely from the cementum beneath the junctional epithelium to the alveolar crest.

extends at a right angle from the long axis of the tooth from cementum to the alveolar bone.

largest group or principal p.f.; extends from the cementum to the alveolar bone.

radiates from the apical cementum to the alveolar bone at the base of the socket.

part of alveolar process that lines the bony sockets into which the roots of the teeth are embedded.

part of the bone which surrounds the Alveolar bone proper and gives support to the sockets.

part of oral mucosa that covers the alveolar processes of the jaw and surrounds the cervical area of the teeth.

surrounds the tooth in a collar like fashion and is not directly attached to the tooth surface (1.5-2mm wide).

the portion of gingiva extending from the gingival margin to the alveolar mucosa.

V-shaped shallow crevice. Presence of curricular fluid (1.8 mm).

occupies the gingival embrasure.

lines the alveolar bone of the oral cavity. Muco-Gingival Junction.

Identify

Five Surfaces of the Teeth

Facing towards the cheek area or buccal mucosa.

Teeth facing towards the lips.

All surfaces facing towards the tongue area.

Surface of the premolars and molars which comes in contact with those in the opposite jaw during the act of closure.

Facing towards the adjoining teeth in the same dental arch.

median line of the face.

area of the medial and distal surface of a tooth which touches its neighboring tooth in the same arch.

proximal surfaces facing towards the median line.

surfaces most distant or away from the midline.

an elevation or mound on the crown portion of a tooth

small elevation on some portion of the crown produced by an extra formation of enamel.

Latin word for ‘girdle’. Is the lingual lobe of an anterior tooth.

any linear elevation on the surface of a tooth and is named according to location.

an irregular depression or concavity. Formed where there is a junction of grooves.

found on molars and premolars on the occlusal surfaces medial or distal to marginal ridges.

is a shallow groove or line between the primary parts of the crown or root.
