Which of the following is a problem relating to the improper use of a laterally positioned flap employed to cover a dehiscence?
1. Extreme patient discomfort
2. Presence of undetected occlusal trauma
3. Creation of a new dehiscence at the donor site
4. Severe infection
Periodontics
Answer: 3
If a laterally positioned flap is not properly designed or secured, it can lead
to complications such as tearing or failing to fully cover the dehiscence,
potentially causing a new dehiscence at the donor site.
Craters in facial and lingual interdental bone are best eliminated by
1. Gingivectomy
2. Osseous reconturing
3. Osseous regeneration procedure
4. Curettage
Periodontics
Answer: 3
Craters in facial and lingual interdental bone are best eliminated by osseous regeneration procedures.
The following most frequently forms at tooth-tissue interface following flap surgery or curettage
1. Scar formation
2. Adhesion of collagen fibres
3. Long junctional epithelium
4. Collagen fibres parallel to root surface
The most frequently formed tissue at the tooth-tissue interface following flap surgery or curettage is long junctional epithelium.
Radiographs alone can be used to accurately determine the
1. presence of calculus
2. anatomic root length
3. presence of an apical abscess
4. severity of gingivitis
Periodontics
Answer: 2
Radiographs allow clinicians to see the anatomical structure of the root;
however, they often cannot accurately assess conditions like the presence of
calculus or severity of gingivitis.
Which of the following is the main constituent of plaque?
1. Calcium and phosphorus
2. Water
3. Microorganisms
4. Glycoproteins and monosaccharides

1. Other side of the same teeth
2. Tooth surface immediately adjacent to the working area
3. Opposing arch
4. None of the above
Periodontics
Answer: 2
In the conventional finger rest, the finger rest is established on the tooth surface immediately adjacent to the working area.
For interproximal areas of disastemata or for wide interdental spaces to properly adopt the interproximal papilla against the bone, the recommended technique to suturing method is
1. Interdental ligation
2. Horizontal mattress suture
3. Continuous, independent sling suture
4. Closed anchor suture
Periodontics
Answer: 2
The recommended suturing method for interproximal areas of diastemata is horizontal mattress suture.
