The finger rest established on tooth surfaces on the opposite side of the same arch is known as
1. Conventional finger rest
2. Opposite arch finger rest
3. Cross-arch finger rest
4. Finger-on-finger rest
The finger rest established on tooth surfaces on the opposite side of the same arch is known as cross-arch finger rest.
Which of the following is the main constituent of plaque?
1. Calcium and phosphorus
2. Water
3. Microorganisms
4. Glycoproteins and monosaccharides
Periodontics
Answer: 3
Dental plaque is primarily made up of microbial communities, which play a
significant role in the development of dental diseases like caries and
periodontal disease.
Efficient way of calculus removal is
1) A relaxed instrument grasp and light lateral working strokes
2) A tight instrument grasp and light lateral working strokes
3) A tight instrument grasp and firm lateral working strokes
4) None of the above
Periodontics
Answer: 3
Explanation:
For effective calculus removal, a tight instrument grasp combined with firm lateral working strokes is essential. This technique allows for better control and application of force, which is necessary to effectively dislodge calculus from the tooth surface.
The purpose of guided tissue regeneration is
1. Prevention of epithelial migration
2. Elimination of junctional and pocket epithelium
3. Complete removal of all irritants
4. Careful curettage of the pocket wall surface
Periodontics
Answer: 1
The purpose of guided tissue regeneration is to prevent epithelial migration.
Which aspect of instrument determines whether to remove gross deposits of calculus
1) Angulation and flexibility of blade
2) Angulation and flexibilty of shank
3) Angulation and length of blade
4) Angulation and length of shank
Periodontics
Answer: 2
The angulation and flexibility of the shank are crucial in determining the ability of an instrument to remove gross deposits of calculus. The shank of a dental instrument, such as a scaler or curette, must be designed to allow for proper access and manipulation around the curves and contours of teeth to effectively remove calculus. While the blade also plays a role, the shank's design is more influential in reaching and adapting to the tooth's surface.
The operator position to perform scaling mandibular right posterior extent on lingual aspect is
1. Front position
2. Left side of the patient
3. Right side of the patient
4. Back position
Periodontics
Answer: 1
The operator position to perform scaling on the mandibular right posterior extent on the lingual aspect is the front position.
Contraindication for distal wedge removal for periodontal surgery in mandibular molar area is
1. Distal root flutings
2. Presence of deep pockets
3. Insufficient space between distal molar & ascending ramus
4. A soft retromolar pad
Periodontics
Answer: 3
A contraindication for distal wedge removal for periodontal surgery in the mandibular molar area is insufficient space between the distal molar and ascending ramus.
Which of the following periodontal diseases does not have calculus:
1. ANUG.
2. Chronic adult periodontitis.
3. Juvenile periodontitis.
4. Periodontal abscess.
Periodontics
Answer: 3
Juvenile periodontitis, now referred to as localized aggressive periodontitis, is characterized by the loss of periodontal attachment and bone in adolescents and young adults, often without the presence of significant calculus. This distinguishes it from other forms of periodontitis, where calculus is typically present.
