BASIC TERMINOLOGIES Flashcards
This is defined as the study of the development,
morphology, function, and identity of each
of the teeth in the human dentitions, as
well as the way in which the teeth relate in
shape, form, structure, color, and function
to the other teeth in the same dental arch
and to the teeth in the opposing arch.
Dental anatomy
This is all of the teeth in the mouth together.
Dentition
What are the two types of dentition?
Primary dentition and Permanent dentition
This is the one we have during childhood.
Primary dentition
This is the one that we will hopefully last throughout our adulthood.
Permanent dentition
This is the teeth in the upper jawbones (called the maxillae).
Maxillary arch
This is teeth in the lower jawbone (called the mandible)
Mandibular arch
This contains one fourth of all teeth in that dentition.
Quadrant
These are the teeth in the front of the mouth, specifically, the incisors and the canines
Anterior teeth
These are the teeth are in the back of the mouth, specifically, the premolars and the molars.
Posterior teeth
This is the surface toward the face, that is, the surface of a tooth in the mouth resting against or next to the cheeks or lips.
Facial, buccal, and labial.
This is the surface of a maxillary or mandibular tooth nearest the tongue
Palatal and lingual
What are the 2 proximal surfaces?
Mesial and Distal
This is the surface closer to the midline.
Mesial
This is the surface farther from the midline.
Distal
This is the chewing surface of a posterior tooth.
Occlusal
This is the Anterior teeth (incisors and
canines) do not have an occlusal surface but
do have a cutting incisal edge or ridge.
Incisal
This is normally present in a child from the ages of about two to six years.
Primary dentition
How many teeth are there in primary dentition?
20 teeth
How many teeth are there in each quadrant of primary dentition?
5 teeth
What is the other term for primary dentition?
Deciduous dentition
What are the 3 classes of teeth in primary dentition?
Incisor, canine, and molars
How many teeth are there in permanent dentition?
32 teeth
How many teeth are there in each quadrant of permanent dentition?
8 teeth
What are the 4 classes of teeth in permanent dentition?
Incisors, canines, premolars, and molars
This is the bony socket of a tooth.
Alveolar
This is the junction of two or more surfaces.
Angle
This is the two surfaces.
Line angle
This is the three surfaces.
Point angle
This is an outstanding or unusual variation in form.
Anomaly
This is the small spot or area on the mesial and distal surfaces of a tooth which, when teeth are in good alignment touches the adjacent teeth in the same arch.
Contact area
This is the highest point of a curve, referring to the greatest convexity or bulge on the facial and lingual surfaces of a crown.
Crest of curvature
This is a V-shaped space between the proximal surfaces of two adjoining teeth in contact.
Embrasure
This is a cleft or crevice in a tooth surface as a result from the imperfect fusion of the enamel of adjoining cusps or lobes.
Fissure
This is a rounded or angular depression on the surface of a tooth.
Fossae
This is a linear depression on the surface of a tooth.
Grooves
This is a major division of a tooth believed to be formed during development.
Lobe
This is a rounded or conical prominence on the incisal ridge of a newly erupted incisor.
Mamelon
This is a sharp, pin-point depression usually located at the junction of two or more intersecting developmental grooves or at the termination of a single developmental groove.
Pit
This is a depression extending longitudinally on the mesial or distal surface of a tooth.
Proximal root concavity
This is a linear elevation on the surface of a tooth.
Ridge
This is an imaginary line passing through the geometric center of the root parallel to its long axis
Root axis line
This is an elongated valley in the surface of a tooth formed by the inclines of adjacent cusps or ridges which meet an angle.
Sulcus
This is an imaginary divisions of a tooth crown or root.
Thirds
This is a slightly rounded elevation on the surface of a tooth.
Tubercle
This is a deviation from a normal characteristic.
Variation
