Question 1

Which of the following would be described as a segment that is part of the whole?

Accepted Answer

A lobule is a small segment or lobe that is part of a larger structure or organ, such as in the liver or lungs.

Question 2

The gingival enlargement in this patient was caused by a calcium channel blocker. Which one of the following would likely be the cause?

Accepted Answer

C

Question 3

When antifungal therapy is used to treat angular cheilitis, which diagnostic process is being applied?

Accepted Answer

Antifungal therapy is a treatment process, not a diagnostic process. Therefore, it falls under the category of therapeutic interventions.

Question 4

Which one of the following is not considered a variant of normal?

Accepted Answer

Fordyce granules, leukoedema, and linea alba are all considered variants of normal and are commonly seen in the oral cavity. Pyogenic granuloma, on the other hand, is a reactive, non-neoplastic soft tissue growth that can occur in response to local irritation or trauma and is not considered a variant of normal.

Question 5

Ectopic geographic tongue can be found:

Accepted Answer

Ectopic geographic tongue refers to the presence of geographic tongue-like lesions on mucosal surfaces other than the tongue.

Question 6

Which papillae are elongated in the condition called black hairy tongue?

Accepted Answer

Black hairy tongue is a condition in which the filiform papillae on the tongue become elongated and produce a hairy or furry appearance. The other papillae (circumvallate, foliate, and fungiform) are not typically affected in this condition.

Question 7

A small circumscribed lesion usually less than 1 cm in diameter that is elevated or protrudes above the surface of normal surrounding tissue is a:

Accepted Answer

A papule is a small, elevated lesion that is usually less than 1 cm in diameter. It is different from a macule, which is a flat, discolored area of skin, and from a vesicle or bulla, which are fluid-filled lesions. Therefore, option A is the best choice for the given description.

Question 8

A Stafne bone cyst contains:

Accepted Answer

A Stafne bone cyst, also known as a Stafne defect, typically contains salivary gland tissue, often from the submandibular gland, and is not a true cyst.

Question 9

In internal resorption the radiolucency seen radiographically is usually:

Accepted Answer

In internal resorption, the radiolucency seen radiographically is usually diffuse. This is because the resorptive process occurs within the tooth, resulting in a widening of the root canal space and loss of dentin, leading to a diffuse appearance on radiographs. Well-circumscribed or multilocular radiolucent areas may be indicative of other types of pathology, such as cysts or tumors. Unilocular radiolucencies are more commonly associated with periapical pathology such as periapical cysts or abscesses.

Question 10

Which one of the following is diagnosed through clinical diagnosis?

Accepted Answer

Fordyce granules are diagnosed through clinical diagnosis as they are visible as small, painless, pale spots on the oral mucosa, typically requiring no further diagnostic tests.

Question 11

A lesion with a stemlike base is described as:

Accepted Answer

A lesion with a stemlike base is described as pedunculated, meaning it is attached to the underlying tissue by a stalk or stem.

Question 12

Another name for geographic tongue is:

Accepted Answer

Geographic tongue is also known as benign migratory glossitis. This is a condition in which a person's tongue has irregular, smooth, red patches on it. These patches can change in size and shape, and can move around the tongue throughout the day. The patches are caused by the loss of the tiny bumps on the tongue's surface, which are called papillae.

Question 13

Which one of the following is not diagnosed through clinical diagnosis?

Accepted Answer

Compound odontoma is typically diagnosed through radiographic examination rather than clinical diagnosis.

Question 14

Radiographic features, including the cotton wool effect and hypercementosis, are especially helpful to the diagnosis of:

Accepted Answer

The cotton wool effect and hypercementosis are characteristic radiographic features of Paget disease, a condition that affects bone metabolism.

Question 15

This gray-white opalescent film seen on the buccal mucosa of 85% of black adults is a variant of normal that requires no treatment. On the basis of this description, you suspect that this is a:

Accepted Answer

Leukoedema is a common benign condition characterized by a gray-white opalescent appearance on the buccal mucosa, often seen in black adults, and does not require treatment.

Question 16

Which one of the following is considered a genetic/inherited disorder?

Accepted Answer

Amelogenesis imperfecta is a genetic disorder that affects the development of tooth enamel. It can lead to teeth that are discolored, misshapen, and prone to breaking or wearing down quickly. Linea alba, necrotizing ulcerative gingivitis, and internal resorption are all dental conditions that are not genetic or inherited disorders.

Question 17

A lesion with a sessile base is described as:

Accepted Answer

Sessile describes the base of a lesion that is flat and broad. An ulcer is a break in the surface epithelium. A stemlike lesion is referred to as pedunculated. A pedunculated lesion is stemlike or stalk-based (similar to a mushroom).

Question 18

Retrocuspid papillae are located on the:

Accepted Answer

Retrocuspid papillae are small, benign nodules found on the gingiva of the lingual aspect of the mandibular canines.

Question 19

Which one of the following conditions would most likely respond to therapeutic diagnosis?

Accepted Answer

Therapeutic diagnosis is a method of diagnosis in which the clinician prescribes a treatment based on the presenting signs and symptoms. Angular cheilitis, which is a fungal infection that commonly occurs at the corner of the mouth, is a condition that can be diagnosed through therapeutic diagnosis. Treatments such as antifungal creams or ointments can be prescribed, and if the condition resolves, it confirms the diagnosis. The other conditions listed (amelogenesis imperfecta, Paget disease, and Stafne bone cyst) require other diagnostic methods such as imaging or clinical examination.

Question 20

This bony hard radiopaque structure in the midline of the hard palate is genetic and autosomal dominant. The diagnosis is made through clinical diagnosis. You suspect a:

Accepted Answer

The answer of  This bony hard radiopaque structure in...
