lala Flashcards
. It has an extremely thin enamel and dentin surrounding an enlarged
radiolucent pulp.
REGIONAL ODONTODYSPLASIA (GHOST TEETH)
An accessory cusp located on the lingual surface that resembles an eagle’s
talon.
TALON CUSP
. The teeth mostly missing are the last teeth of each series.
hypodontia
. The tooth is faced at an angle towards the front of your mouth.
Mesial Impaction
. An accessory cusp that takes the form of fifth cusp.
CUSP OF CARABELLI (CARABELLI TUBERCLE)
The generalized pattern shows the teeth as small and maybe white, yellow, or brown and the enamel is quite thin.
Hypoplastic
. This refers to six or more missing teeth.
Oligodontia
The defect occurs in the initial stages of enamel formation where the
enamel may have a normal thickness but the tooth is too soft.
Hypocalcified
. A genetic syndrome that is characterized by the formation of colorectal
polyps and increases the risk of colorectal cancer.
Gardner’s syndrome -
The loss of tooth structure from mechanical wear from the friction of a foreign body on a tooth surface.
ABRASION
. A congenital absence of teeth because of failure of development of tooth.
ANODONTIA
The teeth is angulated towards the back of your mouth.
Distal Impaction
A kind of fusion that occurs after root formation has been completed and the teeth is united by their cementum
CONCRESCENCE
These are additional number of teeth, over and above the usual number for the dentition.
Supernumerary Teeth
. These teeth are always 0.5 mm or more below the intact marginal ridges of
the adjacent teeth.
SUBMERGED TEETH
. The crowns are of normal size and shape but have large and rectangular
bodies.
TAURODONTISM
This is the incomplete division of a single tooth bud that makes the tooth have two crowns or a large crown partially separated.
GEMINATION
A tooth that occurs in the anterior maxilla mostly between the central incisors that is also a major cause of diastema.
MESIODENS
An X-ray of the affected area typically show teeth with short roots and open
ends.
. REGIONAL ODONTODYSPLASIA (GHOST TEETH)
. This is the abnormal angulation or bend in the root of a tooth.
DILACERATION
The removal of these kinds of impactions will depend on the degree of the angle and in most cases, dentists will wait a year or two before deciding on whether or not the tooth should be removed.
Distal Impaction
The teeth are larger than the average teeth and are more common in males.
MACRODONTIA / megadontia
These kinds of impactions in most cases lead to a partial eruption of the tooth.
Mesial Impaction
. An anomaly where two permanent teeth have exchanged their positions in the same dental arch.
TRANSPOSED TEETH
The union of two or more adjacent tooth germs that is mostly seen in the mandibular anterior teeth usually the lateral incisor and canine
FUSION (SYNODONTIA)
This kind of anomaly only affects a single tooth in the dental arch.
FOCAL MICRODONTIA
This kind of anomaly affects all the teeth in the dental arch.
Microdontia / generalized microdontia
In this kind of anomaly, the canine is the most often involved, interchanging its position with the first premolar.
TRANSPOSED TEETH
This is an ectopic mass of enamel usually found at the furcation area of roots.
ENAMEL PEARL
An invagination or deepening of the calcified layers of a tooth into the body of the tooth.
DENS IN DENTE (DENS INVAGINATUS, DILATED COMPOSITE ODONTOME)
