Dental Eruptions and Anomalies Quiz

Delayed eruption is when a tooth doesn't emerge within the normal timeframe, typically 12 months of the expected age or when root development reaches 75% completion.

The point in time when the first part of a tooth's crown or cusp becomes visible through the gum tissue.

The stage in tooth development where approximately three-quarters of the root has formed, and eruption should occur. A critical marker for timely eruption.

Changes in tooth structure, appearance, or eruption resulting from external factors.

Changes in the number, size, shape and structure of teeth occurring during the developmental period.

problems with tooth emergence restricted in a specific area in the mouth

A condition where tooth eruption is delayed beyond the normal timeframe, potentially associated with underlying systemic diseases.

Teeth present at or shortly after birth

Teeth appearing within the first 30 days of life

Teeth erupting earlier than typically expected.

Teeth that remain unerupted or partially erupted beyond the expected time due to an obstruction.

Unerupted deciduous teeth, very uncommon.

Mandibular third molars, maxillary third molars, maxillary canines, and mandibular premolars.

A factor involved in the obstruction of teeth movement.

Teeth fused to the jawbone, preventing movement.

Teeth next to an ankylosed tooth leaning towards it.

Teeth growing excessively above their normal positions.

Local loss of bone supporting a tooth, caused by an ankylosed tooth.

Permanent tooth unable to fully erupt due to an ankylosed tooth.

Abnormal bite patterns caused by ankylosed teeth, misalignment.

Forces used to move teeth in treatment.

Ankylosis in baby teeth

Removing a permanent tooth in an effort to solve the ankylosis problem.

Restoration to augment the occlusal height of teeth (filling)

Treatment to preserve space for a permanent tooth.

Displacement or loosening of a tooth.

Checking after six months for any positive response to treatment.

Extra teeth that develop in addition to the normal set.

When two teeth switch places in the dental arch.

Misaligned teeth that need treatment like orthodontics or extraction.

Teeth present at birth or shortly after.

Teeth emerging later than expected.

Generally removal during the mixed dentition phase to minimize aesthetic and functional problems.

Extra teeth in the front of the mouth.

Delayed eruption, resorption of adjacent teeth, crowding and malocclusion, & potentially infection.

Baby teeth that fail to fully emerge.

A condition where one or more teeth are missing.

Treatment approach depends on the number of missing teeth, ranging from no treatment to prosthetic replacement and orthodontics.

Presence of extra teeth.

Extra teeth that are normal in size and shape.

Extra teeth that are abnormal in shape and smaller in size.

Abnormal eruption where normal teeth erupt in a swapped position.

Teeth are abnormally large.

Frequency of extra teeth varies by ethnicity and is more common in permanent teeth than deciduous teeth.

The lack of development of one or more teeth.

The development of an increased number of teeth.

The lack of development of six or more teeth, excluding third molars.

A total lack of tooth development.

Smaller than normal development of teeth.

Larger than normal development of teeth.

Two or more teeth fuse during development.

Teeth develop separately but come together.

A disorder affecting enamel formation in teeth.

A disorder affecting dentin formation in teeth.

A disorder affecting dentin and pulps in teeth.

A disorder affecting dentin and pulses in teeth.

A disorder causing abnormal tooth development in certain regions.

Teeth with a large pulp chamber.

Excessive development of cementum around the root.

Extra cusps on teeth.

A groove or pit-like formation in the crown.

Enamel formation in abnormal locations.
