Pericoronitis is seen in relation to
1) Impacted third molars only
2) Around incompletely erupted crown
3) Completely erupted crowns only
4) None of the above
Oral Surgery
Answer: 2
Pericoronitis is an inflammation of the soft tissue surrounding the crown of an incompletely erupted tooth, commonly seen around the third molars (wisdom teeth) but can also occur with other teeth. The condition arises when food particles, bacteria, and plaque accumulate around the partially erupted molar, leading to localized infection.
Thus, pericoronitis is most commonly associated with teeth that are not fully erupted

Compbell line is seen in
1. Transpharyngeal view
2. Transorbital view
3. Occipitomental view
4. Towne view
Oral Surgery Answer: 3
The Campbell line is an important anatomical reference line
used in radiology, particularly in the context of the occipitomental
view (also known as the Water's view). This line is drawn from the
outer canthus of the eye to the midpoint of the maxillary sinus and is used to
assess the position of the maxillary sinuses and other related structures in the
skull.
Occipitomental view: This view is commonly used in
maxillofacial imaging to visualize the maxillary sinuses, orbits, and nasal
cavity. The Campbell line helps in evaluating the relationship of these
structures.
Transpharyngeal view: This view is used to visualize the
pharynx
Transorbital view: This view focuses on the orbits and
surrounding structures
Towne view: This view is used to visualize the occipital
bone and the base of the skull
