Question 1

Teeth that exhibit pulpal obliteration:&#10;A) Require extraction.&#10;B) Require endodontic therapy.&#10;C) Require occlusal restoration.&#10;D) Do not require treatment.

Accepted Answer

Teeth with pulpal obliteration often do not require treatment unless there are symptoms or other complications, as the pulp chamber is naturally calcified and the tooth remains asymptomatic.

Question 2

Condensing osteitis most frequently involves the ____ tooth.&#10;A) Mandibular premolar&#10;B) Mandibular molar&#10;C) Maxillary premolar&#10;D) Maxillary molar

Accepted Answer

Condensing osteitis most frequently involves the mandibular molar due to its common exposure to chronic irritation or infection, often from dental caries or pulpitis.

Question 3

Pulp stones ____ cause symptoms and ____ require treatment.&#10;A) Do; do&#10;B) Do; do not&#10;C) Do not; do&#10;D) Do not; do not

Accepted Answer

Pulp stones are calcifications found in the dental pulp and are usually asymptomatic, not requiring treatment unless they interfere with dental procedures.

Question 4

The periapical abscess:&#10;A) Refers to a tooth with an infection in the pulp.&#10;B) Is a purulent inflammation within the periodontal tissues.&#10;C) Is treated with deep scaling and debridement.&#10;D) Both b and c.

Accepted Answer

The periapical abscess specifically refers to an infection in the pulp of a tooth. It is not a purulent inflammation within the periodontal tissues (choice B) and is not primarily treated with deep scaling and debridement (choice C).

Question 5

Condensing osteitis is seen ____ the apex of a ____ tooth.&#10;A) Below; vital&#10;B) Below; nonvital&#10;C) Above; vital&#10;D) Above; nonvital

Accepted Answer

Condensing osteitis is typically seen below the apex of a nonvital tooth. This occurs due to chronic inflammation and irritation of the periapical tissues, leading to new bone formation.

Question 6

____ resorption is a process seen with the normal shedding of primary teeth.&#10;A) Physiologic&#10;B) Pathologic&#10;C) External&#10;D) Internal

Accepted Answer

Physiologic resorption is a natural process of shedding primary teeth to allow permanent teeth to erupt. Pathologic resorption occurs due to disease or injury, while external and internal resorption refer to the location of the resorption on the tooth surface (external) or within the tooth structure (internal).

Question 7

The treatment for condensing osteitis is:&#10;A) Extraction.&#10;B) Root canal therapy.&#10;C) Osseous recontouring.&#10;D) No treatment is necessary.

Accepted Answer

Condensing osteitis is a reaction to low-grade inflammation, often from a tooth with a necrotic pulp or one that has undergone root canal therapy. It is usually asymptomatic and does not require treatment unless symptoms develop.

Question 8

____ is the complete displacement of a tooth from alveolar bone.&#10;A) Luxation&#10;B) Intrusion&#10;C) Extrusion&#10;D) Avulsion

Accepted Answer

Avulsion is the complete displacement of a tooth from alveolar bone, whereas luxation is a partial displacement, intrusion is when the tooth is pushed into the alveolar bone, and extrusion is when the tooth is pulled out of the alveolar bone partially.

Question 9

Root fractures occur most often in the ____ region.&#10;A) Maxillary central incisor&#10;B) Mandibular central incisor&#10;C) Maxillary molar&#10;D) Mandibular molar

Accepted Answer

Root fractures occur most often in the maxillary central incisor region due to its prominent position and vulnerability to trauma.

Question 10

Sclerotic bone is seen below the apices of ____ teeth.&#10;A) Vital, carious&#10;B) Vital, noncarious&#10;C) Nonvital, carious&#10;D) Nonvital, noncarious

Accepted Answer

Sclerotic bone is a sign of root proximity or trauma and is typically seen below the apices of vital, noncarious teeth. Nonvital teeth may have wider areas of sclerotic bone due to a lack of blood supply. Carious teeth may have areas of resorption rather than sclerotic bone.

Question 11

Teeth that have been luxated should be evaluated by a(n) ____ radiograph.&#10;A) Bite-wing&#10;B) Periapical&#10;C) Occlusal&#10;D) Panoramic

Question 12

____ is a diffuse calcification of the pulp chamber and pulp canals of teeth.&#10;A) Pulpal sclerosis&#10;B) Pulpal obliteration&#10;C) Pulp stones&#10;D) Internal resorption

Accepted Answer

The answer of ____ is a diffuse calcification of the...

Question 13

Which of the following is a periapical radiolucency?&#10;A) Hypercementosis&#10;B) Condensing osteitis&#10;C) Periapical cyst&#10;D) Sclerotic bone

Question 15

Periapical cysts account for ____ of all cysts in the oral region.&#10;A) 10% to 20%&#10;B) 20% to 25%&#10;C) 25% to 50%&#10;D) 50% to 70%

Accepted Answer

The answer of Periapical cysts account for ____ of all...

Question 16

____ is a well-defined radiopacity that is seen below the apex of a nonvital tooth with a history of a long-standing pulpitis.&#10;A) Condensing osteitis&#10;B) Periodontal abscess&#10;C) Sclerotic bone&#10;D) Periapical abscess

Accepted Answer

The answer of ____ is a well-defined radiopacity that is...

Question 17

____ is the most common periapical radiopacity observed in adults.&#10;A) Hypercementosis&#10;B) Sclerotic bone&#10;C) Condensing osteitis&#10;D) Pulpal sclerosis
