MDS PREP
Failures in maintaining adequate plaque control result mostly from failures in patient
1. neuromuscular skills
2. motivation
3. records
4. recalls
Periodontics
Answer: 2
The primary reason for failures in maintaining adequate plaque control is often
a lack of motivation. Patients may understand the importance of oral hygiene but
may not be motivated to implement effective brushing and flossing techniques
consistently.
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 the facial and lingual interdental bone are typically associated with periodontal disease and result from the loss of bone due to inflammation and infection. Osseous regeneration procedures, such as guided bone regeneration (GBR) or the use of bone grafts, are specifically designed to restore lost bone structure. These procedures promote the growth of new bone in the affected areas, effectively filling in the craters and restoring the contour of the alveolar ridge. Gingivectomy and curettage are more focused on soft tissue management and do not address the underlying bone loss, while osseous recontouring may not be as effective in restoring lost bone volume.
The main blood supply to the buccal marginal gingiva is from the
1. subperiosteal vessels
2. interdental alveolar blood vessels
3. main artery of the pulp
4. supraperiosteal vessels
Periodontics
Answer: 4
The buccal marginal gingiva receives its main blood supply from the supraperiosteal vessels, which are located above the periosteum (a layer of connective tissue that covers the bone). These vessels are part of the periodontal ligament's blood supply and provide nutrients to the superficial tissues of the gum
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.
Histologic examination of desquamative gingivitis shows
1. Hyperkeratosis
2. Loss of retepegs
3. Loss of basement membrane
4. All of the above
Histologic examination of desquamative gingivitis shows loss of basement membrane.
what %age of NaF is used in iontophoresis:
1.1%
2.2%
3.3%
4.4%
Periodontics
Answer: 2
2% NaF is used in iontophoresis. This fluoride treatments brings about granular precipitation in dentinal tubules and reduces tubular diameter.
ANUG affects the
1. Attached gingiva
2. Marginal gingiva
3. Alveolar mucosa
4. Interdental papilla
Periodontics
Answer: 4
ANUG primarily affects the interdental papilla.
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.
