Circumvallate b. Foliate c. Filiform d. Fungiform ANS: C The filiform papillae are composed primarily of keratin and are the papillae that elongate in black hairy tongue. Circumvallate papillae on the posterior dorsal tongue do not elongate. Foliate papillae are located on the posterior lateral borders of the tongue. They are vertical, slightly exophytic folds of tissue located in the same area as the lingual lymphoid tissue (lingual tonsils) and do not elongate. Fungiform papillae on the dorsal areas do not elongate. REF: Hairy Tongue, page 24 OBJ: 3 21. Diagnosis of anemia is best accomplished through which examination? a. Laboratory tests b. Evaluation of the color of the gingiva c. Bleeding on probing d. Patient medical history ANS: A Laboratory blood tests provide the best information with which to diagnose anemia. Although the color of the gingiva may be a clinical sign, a diagnosis of anemia, or more specifically the type of anemia, must be made through laboratory testing. Bleeding on probing is not useful in the diagnosis of anemia. The patient’s medical history may be helpful in the diagnosis of anemia, but it is only contributory. The final diagnosis comes from appropriate laboratory tests. REF: Laboratory Diagnosis, page 16 OBJ: 3 22. A radiolucency that “scallops around the roots of teeth” is often used to describe which condition? a. Traumatic bone cyst b. Stafne bone cyst c. Lingual mandibular bone concavity d. Median palatine cyst ANS: A Scalloping around the roots is a term often used to describe the radiographic appearance of a traumatic bone cyst. A Stafne bone cyst usually presents as an oval radiolucency anterior to the angle of the ramus and inferior to the mandibular canal. A lingual mandibular bone concavity is the same lesion as a Stafne bone cyst. A median palatine cyst is a developmental cyst that presents as a unilocular radiolucency found in the midline of the hard palate.

When geographic tongue occurs on the dorsal tongue, the erythematous areas are described as a. inflamed. b. depapillated. c. allergic. d. fungal. ANS: B In geographic tongue, the erythematous areas on the dorsal tongue are devoid of filiform papillae and therefore are appropriately described as depapillated. The erythematous areas seen on the dorsal tongue in geographic tongue are not caused primarily by inflammation. Geographic tongue is not an allergic reaction. Geographic tongue is not a fungal infection. REF: Geographic Tongue, page 24 OBJ: 7 24. It has been suggested that Candida albicans is associated with which condition? a. Median rhomboid glossitis b. Linea alba c. Leukoedema d. Retrocuspid papillae ANS: A Research has suggested that median rhomboid glossitis may be associated with Candida albicans. Linea alba is a variant of normal. Leukoedema is a variant of normal. Retrocuspid papillae are developmental and found on the gingiva of the lingual aspect of mandibular canine teeth. REF: Median Rhomboid Glossitis, page 23 OBJ: 7 25. Which term is used to describe a radiographic lesion with borders that are specifically defined, revealing the exact margins and extent of the lesion? a. Unilocular b. Well circumscribed c. Diffuse d. Multilocular ANS: B Well circumscribed defines a lesion with borders that are specifically defined and in which one can see the exact margins and extent of the lesion. Unilocular means having one compartment or unit that is well defined (as in a radicular cyst). Diffuse describes a lesion with borders that are not well defined. Multilocular lesions are described radiographically as resembling “soap bubbles” (i.e., a lesion with many lobes beyond the confines of one distinct area). REF: Vocabulary, Radiographic Terms Used to Describe Lesions in Bone, page 5 OBJ: 1 26. Fordyce granules a. are ectopic sebaceous glands. b. are seen on the dorsal surface of the tongue. c. require antibiotic treatment. d. are lesions that require biopsy for diagnosis. ANS: A Fordyce granules are ectopic sebaceous glands. Fordyce granules are seen on the buccal and labial mucosa, not the dorsal tongue. Fordyce granules require no treatment. Fordyce granules are diagnosed through clinical appearance. Biopsy is not necessary. REF: Fordyce Granules, page 20 OBJ: 4 27. The base of this lesion is correctly described as a. pedunculated. b. lobule. c. bulla. d. sessile. ANS: D The base of this lesion is sessile, or broad and flat. A pedunculated lesion has a stemlike base similar to that of a mushroom stem. A lobule is a segment or lobe that is part of the whole. A bulla usually contains serous fluid and looks like a blister. REF: Vocabulary, Clinical Appearance of Soft Tissue Lesions, Fig. 1.5, A, pages 1, 3 OBJ: 1 28. This torus palatinus is correctly described as a. bullous. b. papular. c. lobulated. d. nodular. ANS: C This torus palatinus is lobulated (i.e., lobes that are fused together). Bullous lesions contain serous fluid and resemble blisters. A papule is a soft tissue lesion that is elevated above the surface of normal surrounding tissue. A nodule is a palpable solid lesion found in soft tissue. REF: Vocabulary, Clinical Appearance of Soft Tissue Lesions, Fig. 1.1, pages 1, 2 OBJ: 1 29. Another term for an amalgam tattoo is a a. melanoma. b. focal argyrosis. c. nevus. d. multiple myeloma. ANS: B Focal argyrosis is a synonym for amalgam tattoo. A melanoma is a malignant tumor. A nevus is a benign overgrowth of melanocytes. Multiple myeloma is a malignant proliferation of plasma cells. REF: Clinical Diagnosis, page 7 OBJ: 2 30. Which finding is not apparent in leukoedema? a. Intracellular edema in the spinous cells b. Acanthosis of the epithelium c. Generalized opalescence of the buccal mucosa d. A white diffuse material on the buccal mucosa that can be wiped off ANS: D A white diffuse material that can be wiped off is significant in diagnosing pseudomembranous candidiasis. Intracellular edema in the spinous cells is found in leukoedema. Acanthosis of the epithelium is found in leukoedema. Generalized opalescence of the buccal mucosa is seen in leukoedema. REF: Leukoedema, page 23 OBJ: 8 31. Which term best describes an elevated, 5-mm soft tissue lesion containing serous fluid? a. Macule b. Vesicle c. Lobule d. Pustule ANS: B A vesicle is a small (less than 1 cm in diameter), elevated lesion that contains serous fluid. A macule is a flat area usually distinguished by a color different from the surrounding tissue. A lobule is described as a segment or lobe that is part of a whole. A pustule is a circumscribed elevation containing pus. REF: Vocabulary, Clinical Appearance of Soft Tissue Lesions, page 1 OBJ: 1 32. A lesion with a pedunculated base is best described as a. an ulcer. b. stemlike. c. pallor. d. broad and flat. ANS: B A stemlike lesion is referred to as pedunculated. An ulcer is a break in the surface epithelium. Pallor is a paleness of the skin or mucosal tissues. Broad and flat describes the base of a sessile lesion. REF: Vocabulary, Clinical Appearance of Soft Tissue Lesions, page 1 OBJ: 1 33. The following lesions can be identified radiographically except one. Which one is the exception? a. Root resorption b. Fordyce granules c. Interproximal dental caries d. Compound odontoma ANS: B Fordyce granules are yellow clusters of ectopic sebaceous glands that are diagnosed through clinical appearance. Root resorption is identified radiographically when the apex of the tooth appears shortened or blunted. Interproximal dental caries are seen as radiographic radiolucencies. A compound odontoma is initially identified radiographically as a radiopaque area in which tooth structure can be identified
