Pericoronitis is seen in relation to
1) Impacted third molars only

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

Which of the following diseases of the skin is the most likely to exhibit fluid blisters on the skin and/or oral mucosa?
1) Pemphigus
2) Lichen planus
3) Keratosis follicularis
4) Erythema multiforme
Oral Pathology
Answer: 1
Pemphigus is an autoimmune blistering disease characterized by the formation of bullae (fluid-filled blisters) on the skin and mucous membranes, including the oral mucosa. This condition occurs when the body's immune system mistakenly attacks the proteins that bind the layers of the skin together, leading to separation and blistering. The blisters are usually large and painful, and they can rupture easily, leaving raw, exposed areas of skin or mucous membrane.
Lichen planus, keratosis follicularis, and erythema multiforme are other skin conditions but do not typically present with fluid blisters as the main feature.
The base of class III preparation is
1) Axial wall
2) Gingival wall
3) Facial wall
4) Lingual wall
Conservative Dentistry
Answer: 1
In a Class III cavity preparation, which typically involves the anterior teeth and is located on the proximal surfaces, the axial wall is considered the base. This wall is oriented parallel to the long axis of the tooth and provides support for the restoration. The gingival wall is also important, but the axial wall is the primary base in this context.
