Chapter 01: Introduction to Preliminary Diagnosis of Oral Lesions

The compound odontoma is initially identified radiographically as a radiopaque area in which
tooth structure can be identified. No clinical component exists. Mandibular tori are identified
clinically as areas of exostosis on the lingual aspects of mandibular premolars. Fordyce
granules are yellow clusters of ectopic sebaceous glands diagnosed through clinical
appearance. Black hairy tongue is diagnosed clinically. The filiform papillae on the dorsal
tongue elongate and become brown or black. Causes include tobacco, alcohol, hydrogen
peroxide, chemical rinses, antibiotics, and antacids.
