Periodontal pack is least effective in
1) Providing splinting action
2) Haemostatic mechanism
3) Pain elimination
4) Antimicrobial action
Periodontics
Answer: 3
Periodontal packs are primarily used for their antimicrobial, haemostatic, and splinting properties. While they provide a good antimicrobial environment and can aid in haemostasis, they are not typically used for pain elimination. The main purpose of a periodontal pack is to deliver medication directly to the periodontal pocket and help stabilize the gum tissue around the teeth. Pain relief is generally managed through other means such as analgesics or local anesthetics.
When electrosurgery is correctly employed to prepare gingival tissues for making impressions, it will
1. Permanently alter the contour of gingival tissues
2. Reduce the gingival height
3. Remove a thin layer of crevicular gingival tissue
4. None of the above
Periodontics
Answer: 3
When electrosurgery is correctly employed to prepare gingival tissues for making impressions, it removes a thin layer of crevicular gingival tissue.
Systemic conditions which can affect the health of the gingiva are
1. agranulocytos
2. leukemia
3. granulocytopenia
4. all of the above
Periodontics
Answer: 4
agranulocytosis, leukemia, and granulocytopenia—can significantly impact the
health of the gingiva by affecting the immune response and increasing
susceptibility to infections.
A suturing needle used in periodontal surgery should have
1. A swedged suture needle
2. Have rounded point
3. Have double cutting edge
4. All of the above
Periodontics
Answer: 1
A suturing needle used in periodontal surgery should have a swedged suture needle.
Most of the microorganisms present a two day old dental plaque will be
1. lactobacilli
2. fusiform bacilli
3. vibrios
4. cocci
Periodontics
Answer: 4
In the early stages of dental plaque formation, particularly within the first
few days, the predominant microorganisms are typically cocci, especially Streptococcus species.
These bacteria are among the first to colonize the tooth surface after a
cleaning, forming a biofilm.
Lactobacilli are more commonly associated with mature
plaque and caries development, as they thrive in acidic environments.
Fusiform bacilli and vibrios are more
commonly found in later stages of plaque development or in specific
conditions, such as periodontal disease.
Thus, in a two-day-old dental plaque, the majority of microorganisms will
indeed be cocci
Cervical abrasion is usually the result of
1. acidic fluids
2. sulcular brushing
3. gingival sulcular fluids
4. horizontal brushing
Periodontics
Answer: 4
Cervical abrasion is often caused by improper brushing techniques, particularly
horizontal brushing, which can wear away the enamel and dentin at the cervical
area of the teeth.
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.
Guided tissue regeneration (GTR) is used mainly in the treatment of
1. Class I furcations
2. Class II furcations
3. Class III furcations
4. All of the above
Periodontics
Answer: 2
Guided tissue regeneration (GTR) is used mainly in the treatment of Class II furcations.
