dental records test 1

Facial / Buccal

The surface of the tooth facing the lips or cheeks.

Lingual

The surface of the tooth facing the tongue (palatal on maxillary teeth).

Mesial

The surface of the tooth that is closest to the midline of the dental arch.

Distal

The surface of the tooth that is farthest from the midline of the dental arch.

Occlusal

The chewing surface of the posterior teeth.

Incisal

The cutting edge of anterior teeth.

Line surfaces

Surfaces formed by the junction of two tooth surfaces.

Point surfaces

Surfaces formed by the junction of three tooth surfaces.

Apical third

The part of the tooth root closest to the tip (apex), often examined for infection.

Middle third

The middle section of the tooth root.

Cervical third

The part of the tooth closest to the gum line, important for assessing brushing habits.

Occlusion

The relationship between maxillary and mandibular teeth when jaws are fully closed.

Malocclusion

Abnormal or incorrect bite relationship between maxillary and mandibular teeth.

Centric occlusion

The position of the jaws that allows maximal stable contact between occluding surfaces.

Functional occlusion

The contact of teeth during biting and chewing movements.

Angles Classification

A system used to describe and classify occlusion and malocclusion based on the maxillary first molar.

Class I (neutrocclusion)

Ideal mesiodistal relationship between jaws and dental arches.

Class II (distocclusion)

Mandible is positioned back, causing maxillary teeth to appear protruded.

Class II Division 1

Flat and parted lips with lower lip behind upper incisors ("buck tooth").

Class II Division 2

Maxillary incisors not in labioversion.

Class III (Mesiocclusion)

Protrusion of the mandible, making biting difficult.

Curve of Wilson

A line across the occlusal surface of the left and right mandibular first molars indicating tipping.

Curve of Spee

The slight curvature of the maxillary and mandibular arches in occlusion.

Closure

The process where posterior teeth come together first as jaws close, as anterior teeth are not designed to support full occlusal forces.

Canine Eminence

Bony covering over the facial aspect of the canine root

What are the different tooth names

Central Incisors, Lateral incisors, Canines, Premolars (2), Molars (3)

Quadrant

4 sections

Sextant

6 divisions

Natural teeth in the dental arch are called

Dentition

Baby or primary teeth are called

Deciduous

Permanent teeth that replace primary teeth are called

Succedaneuous Teeth

teeth located in front of mouth

Anterior

upper jaw

maxilla

lower jaw

mandible

mesial surface

surface of tooth toward the midline

masticatory surface

Chewing surface of teeth

interproximal space

Area between adjacent tooth surfaces

Embrasure

Triangular space in the gingival direction between the proximal surfaces (toothpick space hole i think)

Primary dentition

20 baby teeth

Mixed dentition

between 6-12 years, both primary and permanent teeth

permanent dentition

Adult teeth, 32 teeth

anterior teeth

incisors, canines, 12 total

posterior teeth

Premolars, molars, appears in almost a straight line

what teeth are in the permanent dentition but NOT in the primary dentition

Premolars

what are counters

teeth are not boxes. they are curvy queens, narrow at the root/gumline
