Q

What dental anomaly is represented here?

A

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.

Q

What dental anomaly is represented here?

Study These Flashcards
A

Shovel-shaped

permanent incisors

*More common in American Indians

22
Q

What dental anomaly is represented here?

Study These Flashcards
A

Enamel pearls

on maxillary molar roots, many located near the furcation.

23
Q

What dental anomaly is represented here?

Study These Flashcards
A

Taurodontia

bull or “prism” teeth, very long pulp chamber, without a constriction near the CEJ

24
Q

What dental anomaly is represented here?

Study These Flashcards
A

Dilaceration

dilaceration (or flexion) of the root.

25
What dental anomaly is represented here?
**Extra root and dilaceration** (severe) of a mandibular molar with three instead of two roots.
26
What dental anomaly is represented here?
**Dens in dente** | (“tooth within a tooth”)
27
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.
28
What dental anomaly is represented here?
**Concrescence** the junction or joining of cementum between adjacent teeth.
29
What dental anomaly is represented here?
**Hypercementosis** or excess cementum thickness is evident on a variety of teeth.
30
What dental anomaly is represented here?
Extra roots
31
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.
32
What dental anomaly is represented here?
Unusual bifurcated roots
33
What dental anomaly is represented here?
Unusual **trifurcation** on a maxillary premolar. These roots somewhat resemble those found on maxillary molars- distal view
34
What dental anomaly is represented here?
**Impacted** mandibular third molar
35
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).
36
What dental anomaly is represented here?
**Torsiversion** slight rotation of this tooth #8
37
vWhat dental anomaly is represented here?
**Amelogenesis imperfecta** **-**Faulty enamel Formation is a hereditary disorder affecting enamel formation.
38
vWhat dental anomaly is represented here?
Fluorosis
39
vWhat dental anomaly is represented here?
**Enamel dysplasia (hypoplasia)** This tooth damage resulted from the disruption of enamel formation \*Enamel damage from high fever\*
40
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.
41
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.
42
vWhat dental anomaly is represented here?
**Attrition** results from prolonged bruxism or grinding of the teeth.
43
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.
44
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.
45
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.
46
What dental anomaly is represented here?
focal hypoplasia
47
Condition that is due from tooth to tooth grinding
Attrition
48
Condition due to mechanical wearing of teeth
Abrasion \* as in brushing too hard
49
Condition due to heavy occlusion with enamel chipping off at cervical
Abfraction
50
Condition due to tooth destruction from acids
Erosion
51
What dental anomaly is represented here?
Most unusual dentition
