MDS PREP
After PD surgery immediate recall of patient is done after
1) 1 week
2) 2 week
3) 3 week
4) 4 week
Periodontics
Answer: 1
Following periodontal surgery, a one-week recall is standard practice to
evaluate the surgical site, ensure proper healing, and address any immediate
postoperative concerns.
A teenaged patient reported complaining of sudden drifting of teeth. Bone loss and pockets were found to be more severe on some teeth when compared to neighboring teeth. The most likely diagnosis is
1. simple periodontitis
2. chronic nonspecific periodontitisv
3. juvenile periodontitis
4. gingivosis
Periodontics
Answer: 3
Juvenile periodontitis (now referred to as localized aggressive periodontitis)
is characterized by localized bone loss and periodontal pockets, often affecting
adolescents and young adults. The sudden drifting of teeth and the severity of
bone loss in specific areas align with this diagnosis.
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.
Gingival inflammation extending the deeper supporting tissues and destroying part of the periodontium would be diagnosed as
1 acute necrotizing ulcerative gingivitis
2 chronic gingivitis
3. gingival pathosis
4. juvenile periodontitis
Periodontics
Answer: 4
Juvenile periodontitis involves inflammation that extends beyond the gingiva
into the supporting structures of the periodontium, leading to significant
tissue destruction.
The first sequential step in osseous resection technique
1. Vertical grooving
2. Radicular blending
3. Flattening interproximal bone
4. Gradualising marginal bone
Periodontics
Answer: 1
The first sequential step in the osseous resection technique is vertical grooving.
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
Which one of the following holds good i case of iontophoresis
1) Sodium chloride is used in this technique
2) It is safe to use on people with pacemakers
3) The pulp tester is used for the electric charge
4) It encourages negative ions to penetrate the tooth ions
Periodontics
Answer: 4
Explanation: Iontophoresis is a technique that uses a small electric current to drive charged substances (ions) into tissues. In dentistry, it is often used to deliver fluoride ions into the tooth structure, and it specifically encourages negative ions to penetrate.
Which of the following serves to increase the width of attached gingiva on tooth with isolated gingival recession
1) Laterally positioned pedicle graft
2) Free gingival graft
3) Apically displaced flap
4) All of the above
Periodontics
Answer: 1
Increasing the width of attached gingiva is important for periodontal
health and aesthetics. Here’s how these techniques generally perform:
Laterally positioned pedicle graft involves using
tissue from an adjacent site to augment the width of attached gingiva at
the recession site without losing blood supply, making it quite
effective.
Free gingival graft can also increase attached
gingiva, but since it comes from a donor site, the healing and
appearance may not be optimal compared to pedicle grafts.
Apically displaced flap primarily repositions
existing tissue and may not necessarily increase the width of attached
gingiva.
While options 2 and 3 can contribute to increased connective tissue, they
don't specifically target the enhancement of attached gingival width as
effectively as a laterally positioned pedicle graft.
