Question 14

Exam of 7 yo kid shows : Narrow dental arch, diastema, open mouth posture, abnormal sucking habits. What dx?

Answer 14

Tongue thrusting

Large tonsils and adenoids also contribute to tongue thrust swallowing.

Question 15

Exam of 7 yo kid shows

• open bite
• protrusion of the maxillary incisors
• high and narrow palatal vault
• unilateral crossbite.

Dx?

Answer 15

Thumb (digit) sucking —-> creates an open bite and protrusion of the maxillary incisors. Digit sucking is also implicated in the creation of a high and narrow palatal vault as well as a unilateral crossbite.

Question 16

______ is an enamel hypoplasia of a permanent tooth resulting from an infection of a deciduous tooth.

Answer 16

Turner tooth

The periapical involvement can disturb the ameloblasts of the underlying permanent tooth, creating the anomaly.
