3.Which fascial spaces are affected in Ludwig’s angina?

Unilateral involvement of the submandibular and sublingual spacesBilateral involvement of the submandibular and sublingual spacesUnilateral involvement of the submandibular, sublingual, and submental spacesBilateral involvement of the submandibular, sublingual, and submental spaces

4.Which conditions are included under chronic osteomyelitis of the jaw?

Condensing osteitisSclerotic cemental massChronic diffuse sclerosing osteomyelitisAll of the above

5.Among the following bones, which one is most susceptible to developing osteomyelitis?

6.What is the term for chronic periostitis occurring in children?

CherubismGarre’s osteomyelitisHistiocytosis XTuberculous osteomyelitis

7.Which bacterial enzyme is responsible for causing a widespread, spreading inflammatory lesion?

8.Which method is most effective in distinguishing between a periapical cyst and a periapical granuloma?

9.What is the key distinguishing feature between condensing osteitis and benign cementoblastoma on radiographs?

Condensing osteitis occurs around healthy teeth, while cementoblastoma is linked to dead teeth.In condensing osteitis, the radiopaque area is connected to the tooth, whereas in cementoblastoma it is separate.Cementoblastoma develops adjacent to vital teeth, whereas condensing osteitis is found near non-vital teeth.The radiopaque mass in cementoblastoma is fused to the tooth root, unlike in condensing osteitis where it is not attached.Condensing osteitis and cementoblastoma both show radiopacity attached to the tooth root.

10.Which characteristic is consistently linked to a radicular cyst?

A tooth that is impactedA tooth that is absentA tooth that is non-vitalA tooth with an abnormality

14.What is the main factor that causes reversible pulpitis to progress into irreversible pulpitis?

Constriction of blood vesselsDecreased immune defensePenetration of bacteria into the pulpEnhanced aggressiveness of microbes

15.What type of pain is typically experienced in acute irreversible pulpitis?
