Exam 2 (CH 5 & 6 Crash course)

Question 1

is characterized by well-defined, pear-shaped radiolucency, and is believed to be of odontogenic epithelial origin. When it is large enough, divergence of the roots of adjacent teeth can result.

Answer 1

Globulomaxillary

Question 2

Question 17

The incomplete or defective formation of enamel, resulting in the alteration of tooth form or color

Answer 17

Enamel hypoplasia

Question 18

A mass of thyroid tissue located on the tongue away from the normal anatomic location of the thyroid gland. It is an uncommon developmental anomaly that results from the failure of primitive thyroid tissue to migrate from its developmental location in the area of the foramen cecum on the posterior portion of the tongue to its normal position in the neck. Also called ectopic lingual thyroid nodule.

Answer 18

Lingual thyroid nodule
