Тест: Fundamentals of Oral Pathology and Dental Anomalies — 5 въпроса

1. Why is oral pathology important in dentistry beyond routine clinical inspection?

A. It is used only for dental caries and never for soft tissue lesions

B. It provides microscopic support for diagnosing and understanding oral and maxillofacial diseases

C. It replaces the need for any clinical examination of the mouth

D. It is limited to cosmetic evaluation of tooth color and shape

Answer: (B)

Обяснение

Oral pathology relies on histopathologic practice to support diagnosis and explain disease processes in the oral and maxillofacial region. Clinical observation is still important, but it is not a substitute for microscopic analysis when needed.

2. Why is histopathologic practice particularly important in the field of oral pathology within dentistry?

A. Because routine dental procedures require microscopic examination to ensure quality.

B. Because it replaces clinical observation as the primary diagnostic tool in all dental cases.

C. Because it is only necessary for the diagnosis of systemic diseases that manifest in the mouth.

D. Because it allows for the microscopic diagnosis and understanding of oral diseases, which are diverse and complex.

Answer: (D)

Обяснение

Histopathologic practice is essential because it supports the diagnosis and understanding of various oral and maxillofacial diseases at a microscopic level, especially given the diversity of tissue involvement and lesion types.

3. Which set correctly represents localization-based classification of oral and dental diseases?

A. Inflammatory, reactive, dyscratic, and tumor diseases

B. Enamel, dentin, pulp, and cementum diseases

C. Soft tissue, bone, dental, and salivary gland diseases

D. Congenital, acquired, infectious, and hereditary diseases

Answer: (C)

Обяснение

Localization-based classification groups disorders by the tissue compartment involved: soft tissues, bone, teeth, and salivary glands. The other options describe etiologic or histologic groupings rather than localization.

4. What is a characteristic feature of hypodontia?

A. Enlargement of tooth size

B. Delayed eruption of teeth

C. Congenital absence of one or more teeth

D. Presence of extra teeth

Answer: (C)

Обяснение

Hypodontia refers to the congenital absence of one or more teeth, most often affecting third molars, second premolars, or maxillary lateral incisors. It is distinct from hyperdontia, which involves extra teeth.

5. Which of the following best describes regressive tooth changes such as attrition, abrasion, and erosion?

A. Attrition occurs due to bacterial acids destroying enamel, abrasion is caused by chemical erosion, and erosion is due to aging-related mechanical wear.

B. All three processes—attrition, abrasion, and erosion—are primarily caused by bacterial activity and plaque buildup.

C. Attrition is physiological wear related to chewing and age, abrasion is pathological wear caused by external mechanical factors, and erosion results from chemical processes not involving bacteria.

D. Attrition, abrasion, and erosion are different names for the same process, involving either mechanical or chemical wear of teeth.

Answer: (C)

Обяснение

Attrition is normal wear from chewing that increases with age, while abrasion is caused by external mechanical factors like brushing or improper habits, and erosion results from chemical (non-bacterial) processes like acid exposure.
