Salt-paper appearance is seen in intraoral periapical radiograph of
1) Thalassaemia
2) Sjogren"s syndrome
3) Periodontal abscess
4) Osteoporosis
Radiology
Answer: 1
The "salt-paper" appearance in intraoral periapical radiographs is often associated with thalassemia due to changes in the bone structure.
In thalassaemia, particularly in the case of thalassaemia major, there can be
changes in the bone structure due to marrow hyperplasia and compensatory
changes. This can lead to a "salt-and-pepper" or "salt-paper" appearance on
radiographs, which is characterized by a mottled pattern of radiolucency and
radiopacity in the bones, including the jaw.
Osteoporosis can lead to generalized bone loss and may show decreased bone
density on radiographs
A periodontal abscess typically presents as a localized radiolucency around
the root of a tooth on radiographs
Sjogren's syndrome primarily affects the salivary and lacrimal glands,
leading to dry mouth and dry eyes
What is the primary function of the vestibulospinal tract?
1) Control of posture and balance
2) Control of fine motor skills
3) Control of respiration
4) Control of pupillary response
The vestibulospinal tract is a medial pathway that plays a critical role in maintaining posture and balance by coordinating the contraction of antigravity muscles in response to information from the vestibular system.

The irrigating should used with ultrasonic instruments used for preparation of root canal is
1) Sodium hypochlorite
2) Normal saline
3) Hydrogen peroxide
4) Chloramine
Endodontics
Answer: 1
Sodium hypochlorite is commonly used as an irrigating solution with ultrasonic instruments in endodontic treatment for its antimicrobial properties. It helps in the cleaning and disinfection of the root canal system by removing organic debris and bacteria. Normal saline, hydrogen peroxide, and chloramine are also used as irrigants, but sodium hypochlorite is the most effective in eliminating bacteria.
