Q: The developmental anomaly seen in this radiograph is:
- taurodontism.
- mulberry molar.
- supernumerary roots on the mandibular premolars.
- dilaceration.
A: supernumerary roots on the mandibular premolars.

Q: This radiograph clearly shows which developmental anomaly?
- Dens in dente
- Periapical pathology (PAP)
- Caries
- Open contacts
A: Dens in dente

Q: Enamel hypoplasia is the result of a disturbance of or damage to ameloblasts during enamel matrix formation. Which one of the following would not be a factor?
- Genetics
- Ingestion of high concentrations of fluoride during tooth development
- Vitamin deficiency during tooth development
- Shingles
A: Shingles

Q: Pitting is the most common type of enamel hypoplasia seen in patients who have which condition during tooth development?
- Febrile illness
- Drinking water with 2.4 ppm of fluoride during tooth development
- Congenital syphilis
- Herpes simplex
A: Febrile illness

Q: Ingesting water with four times the amount of fluoride causes:
- brown-to-black staining.
- cusp fractures.
- white spots on the middle third of smooth crowns.
- increased dental caries.
A: brown-to-black staining.

Q: Which one of the following defines a disturbance of the maturation of the enamel matrix?
- Turner tooth
- Mulberry molar
- Premature birth
- Enamel hypocalcification
A: Enamel hypocalcification

Q: The projection of white material seen at the furcation area in this maxillary molar is a developmental anomaly.

You suspect:
- dens evaginatus.
- enamel pearl.
- supernumerary cusp.
- calculus.
A: enamel pearl.

Q: Regional odontodysplasia is:
- a decrease in radiodensity seen on one or more unerupted teeth in a quadrant.
- a genetic condition.
- caused by systemic illness.
- most often seen in the mandible.
A: a decrease in radiodensity seen on one or more unerupted teeth in a quadrant.

Q: Total anodontia is often associated with a hereditary disturbance called:
- taurodontism.
- amelogenesis imperfecta.
- ectodermal dysplasia.
- cleidocranial dysplasia.
A: ectodermal dysplasia.

Q: The most common supernumerary tooth is called:
- distomolar.
- mesiodens.
- mulberry molar.
- Turner tooth.
A: mesiodens.

Q: The supernumerary tooth in this illustration is:
- a mesiodens.
- a dilaceration.
- the result of twinning.
- the result of gemination.
A: a mesiodens.

Q: Nonerupted supernumerary teeth should be extracted because of which of the following risks?
- Malignant tumor development
- Cysts around the crowns
- Internal resorption
- Condensing osteitis
A: Cysts around the crowns

Q: For which condition would pulp vitality be nonvital?
- Radicular cyst
- Median mandibular cyst
- Median palatal cyst
- Periapical cemento-osseous dysplasia
A: Radicular cyst

Q: Dens in dente is a developmental anomaly often seen with:
- extra cusps.
- a periapical lesion.
- tuberculated premolars.
- supernumerary roots.
A: a periapical lesion.

Q: Which tooth is most commonly affected by dens in dente?
- Maxillary central
- Mandibular lateral
- Maxillary lateral
- A supernumerary tooth
A: Maxillary lateral
