Supernumerary mesiodens
What dental anomaly is represented here?
(supernumerary) fourth molars
What dental anomaly is represented here?
peg-shaped maxillary lateral incisor
What dental anomaly is represented here?
Gemination (twinning)
It appears that the tooth germ for tooth #23 split or divided into two. The geminated tooth will generally have a single root and common pulp canal.
What dental anomaly is represented here?
Fusion.
Two teeth appear to be fused together. There are two pulp canals.

Fusion
What dental anomaly is represented here?
Hutchinson incisors
effects of congenital syphilis
What dental anomaly is represented here?
mulberry molar
effects of congenital syphilis
What dental anomaly is represented here?
Extra cusps
What dental anomaly is represented here?
Tuberculum intermedium
Mandibular first and second molars with extra, midlingual cusps, each called a tuberculum intermedium.
What dental anomaly is represented here?
Talon cusps
The lingual defects in all of these teeth could affect the occlusion.
What dental anomaly is represented here?
Tubercles
Elevations or tubercles (or cusplets) on the cingula of a canine and lateral incisor.
What dental anomaly is represented here?
Unusually prominent labial ridge
What dental anomaly is represented here?
Macrodontia
(of very long incisors)
What dental anomaly is represented here?
Microdontia
(of three very short central incisors with dwarfed roots)
What dental anomaly is represented here?
Shovel-shaped
permanent incisors
*More common in American Indians
What dental anomaly is represented here?
Enamel pearls
on maxillary molar roots, many located near the furcation.
What dental anomaly is represented here?
Taurodontia
bull or “prism” teeth, very long pulp chamber, without a constriction near the CEJ
What dental anomaly is represented here?
Dilaceration
dilaceration (or flexion) of the root.
What dental anomaly is represented here?
Extra root and dilaceration
(severe) of a mandibular molar with three instead of two roots.
What dental anomaly is represented here?
Dens in dente
(“tooth within a tooth”)
What dental anomaly is represented here?
Dens in dente
(“tooth within a tooth”)
Radiograph of a dens in dente on a maxillary right central incisor.
What dental anomaly is represented here?
Concrescence
the junction or joining of cementum between adjacent teeth.
What dental anomaly is represented here?
Hypercementosis
or excess cementum thickness is evident on a variety of teeth.
What dental anomaly is represented here?
Extra roots
What dental anomaly is represented here?
Extra roots
Two radiographs showing a right and left mandibular first molar, each with three (instead of two) roots.
What dental anomaly is represented here?
Unusual bifurcated roots
What dental anomaly is represented here?
Unusual trifurcation on a maxillary premolar.
These roots somewhat resemble those found on maxillary molars- distal view
What dental anomaly is represented here?
Impacted mandibular third molar
What dental anomaly is represented here?
Impacted mandibular third molar
A horizontally impacted third molar (#32) has its occlusal surface in contact with the occlusal surface of a fully formed impacted 4th molar (at arrow).
What dental anomaly is represented here?
Torsiversion
slight rotation of this tooth #8
vWhat dental anomaly is represented here?
Amelogenesis imperfecta
-Faulty enamel Formation
is a hereditary disorder affecting enamel formation.
vWhat dental anomaly is represented here?
Fluorosis
vWhat dental anomaly is represented here?
Enamel dysplasia (hypoplasia)
This tooth damage resulted from the disruption of enamel formation
*Enamel damage from high fever*
vWhat dental anomaly is represented here?
Dentinogenesis imperfecta
(opalescent dentin) is a hereditary disorder that affects the dentin and external appearance of all teeth. The teeth take on a gray or yellow opalescent appearance.
*Radiographs reveal the total or partial lack of pulp chambers and canals.
vWhat dental anomaly is represented here?
Tetracycline staining
in this permanent dentition resulted from the administration of tetracycline antibiotic during the time that teeth are forming.
vWhat dental anomaly is represented here?
Attrition
results from prolonged bruxism or grinding of the teeth.
What dental anomaly is represented here?
Abrasion
(sometimes called toothbrush abrasion) is due in part to incorrect horizontal tooth brushing over areas of cementum that are exposed due to the recession of the gingiva.
What dental anomaly is represented here?
Erosion
This pattern of tooth destruction is typically associated with someone with severe acid reflux or repeated regurgitation in bulimic persons.
What dental anomaly is represented here?
Erosion
of facial enamel (at arrows) may be caused by holding pieces of acidic fruit like lemons next to the teeth and sucking on them for an extended period of time, a habit practiced by some persons in Southeast Asia.
What dental anomaly is represented here?
focal hypoplasia
Condition that is due from tooth to tooth grinding
Attrition
Condition due to mechanical wearing of teeth
Abrasion
* as in brushing too hard
Condition due to heavy occlusion with enamel chipping off at cervical
Abfraction
Condition due to tooth destruction from acids
Erosion
