Dental Anomalies Quiz

The absence of one or more teeth, often due to genetic factors.

The absence of more than six teeth, a more severe form of missing teeth than partial anodontia.

A space between the two upper front teeth, also known as a gap.

A thick band of tissue connecting the upper lip to the gum, which can sometimes cause a space between the teeth.

A phase in tooth development, typically around 7.5 years old, where there's a normal spacing between upper front teeth that usually closes as other teeth erupt.

The eruption of a canine tooth into the space intended for a missing lateral incisor. This can lead to a diastema between the central incisor and the canine.

A small, peg-shaped lateral incisor that can lead to a space between the front teeth.

An extra tooth that grows between the upper front teeth, causing crowding and potential gaps.

A supernumerary tooth that is normally shaped and sized, often found alongside a regular tooth.

An extra tooth that can lead to a space between the two front teeth.

A common complication of supernumerary teeth where a normal tooth fails to erupt due to the presence of the extra tooth.

A complication of supernumerary teeth where the roots of nearby teeth are absorbed or damaged.

An inherited or individual variation in tooth size and shape.

A small, peg-shaped lateral incisor that can lead to spaces between the front teeth.

A tooth with a larger-than-normal bulge on the inside surface, which can cause a less than normal overbite.

A facial appearance often seen in mouth breathers, characterized by a contracted upper jaw, protruding upper front teeth, a thickened lower lip, and a long face.

Premature loss of deciduous incisors in the lower jaw can lead to crowding and narrowing of the dental arch. This happens because the front part of the lower jaw resorbs, not leaving enough space for the permanent incisors to erupt properly.

If a primary canine is lost on one side of the lower jaw, the other primary canine should be removed to prevent a shift in the midline, tilting of the front teeth, and an increased overbite.

When a deciduous molar is lost early, crowding usually doesn't happen, but the canine on that side might shift backward, preventing the permanent molar from erupting properly.

Mouth breathing can lead to several dental problems, including an overbite, underbite, and a narrow upper jaw.

If mouth breathing persists even after removing the cause (e.g., polyps), interventions like physical exercises, oral screen, or trainers can be used to correct the habit and help develop proper breathing patterns.

Common signs of mouth breathing include seeing water vapor on a mirror held in front of the nose and the inability to keep the mouth closed for an extended period.

The loss of teeth at an early age can lead to issues like crowding, tooth shifting, and improper eruption of permanent teeth.

A condition where the jaws are smaller than the teeth, leading to crowding and difficulty in aligning teeth.

A condition where the teeth are smaller than the jaws, resulting in gaps between teeth.

The inheritance of jaw size from one parent and tooth size from another, leading to discrepancies that can cause malocclusion.

Inherited traits that determine the relationship between the upper and lower jaws, including the position and alignment of the teeth.

The process of natural selection that has led to changes in jaw size and tooth number over generations, contributing to malocclusion conditions.

Conditions present at birth, which includes abnormal development of bones, teeth, and other structures.

Factors influencing malocclusion that are not inherited, including habits, diet, and disease.

The study of inherited traits, focusing on how genes influence physical characteristics, including skeletal and dental features.

If the second deciduous molar (E) is lost prematurely, the first permanent molar (6) drifts forward, potentially affecting the eruption of the adjacent permanent tooth (5).

Loss of both upper and lower deciduous molars can cause a false Class III malocclusion (pseudoclass III) where the lower jaw appears to be more prominent than the upper jaw.

Unilateral (one-sided) loss of the second deciduous molar (E) can cause a shift in the dental midline, especially in the lower arch.

Prolonged retention of deciduous teeth can happen due to various factors like incomplete root resorption, ankylosis, absence of permanent successors, or abnormal eruption paths.

Loss of an upper incisor can lead to spacing between the remaining incisors.

Loss of a lower incisor can cause a shift in the dental midline.

The loss of a permanent first molar can have significant consequences for the alignment of the other teeth, and overall dental health.

The loss of an upper canine tooth can affect the appearance of the face.

A condition caused by decreased production of thyroid hormone in children, leading to abnormal tooth development, delayed eruption, and tongue enlargement.

A condition caused by insufficient growth hormone production, resulting in short stature, delayed tooth eruption, and incomplete root formation.

A condition characterized by excessive growth hormone production, leading to enlargement of facial bones and fingers.

A condition affecting height due to excessive growth hormone production during childhood, resulting in a very tall body.

A condition caused by decreased secretion of thyroid hormones, leading to abnormal tooth resorption and retention of deciduous teeth.

A condition resulting from excessive growth hormone production in adulthood, causing enlargement of facial bones and fingers.

A condition caused by insufficient growth hormone production during childhood, leading to short stature and delayed tooth development.

A condition caused by excessive growth hormone production during childhood, leading to extreme height.
