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.
Which is an example of non-graft associated regenerative technique
1. HTR polymer
2. Bioactive glass
3. Osseous coagulum
4. GTR
Periodontics
Answer: 4
GTR is an example of a non-graft associated regenerative technique.
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.
Following the application of disclosing solution on teeth, a patient can remove plaque most effectively by using
1. dental floss
2. a strong mouthwash
3. a water irrigating device
4. a soft bristle brush
Periodontics
Answer: 4
A soft bristle brush is the most effective tool for removing plaque after the application of a disclosing solution. It allows for thorough cleaning of the tooth surfaces, including areas that may be difficult to reach with other methods.
A characteristic of gingivitis is
1. vertical bone loss
2. swollen marginal tissue
3. wear of functional cusps
4. apical migration of the epithelial attachment
Periodontics
Answer: 2
Swollen marginal tissue is a hallmark of gingivitis, reflecting inflammation and
edema from plaque accumulation and irritants.
Gore Tex membrane is used during reattachment procedures to
1) Prevent osseous regeneration
2) Prevent connective tissue attachment
3) To prevent formation of long junctional epithelium
4) All of the above
Periodontics
Answer: 3
Gore-Tex is a type of barrier membrane used in guided tissue regeneration (GTR) procedures. Its primary purpose is to prevent the formation of long junctional epithelium, allowing for the regeneration of periodontal tissues, including bone and connective tissue. While it does not directly prevent osseous regeneration or connective tissue attachment, it creates a barrier that favors the regeneration of the desired tissues.
Which of the following procedures is least successful in resolving a periodontally related osseous defect
1. Osseous coagulum graft
2. Resection surgery
3. Reattachment procedure
4. Alloplast graft
The procedure least successful in resolving a periodontally related osseous defect is the reattachment procedure.
