Periodontics - 3 Questions

1
Periodontics
Which of the following flaps eliminates pocket as well as increase width of attached gingiva 
 1. Unrepositioned flap
 2. Apical displaced flap
 3. Laterally displaced flap
 4. Coronally displaced flap

πŸ“ Explanation:

The apical displaced flap is a surgical procedure used in periodontics to treat periodontal pockets and increase the width of attached gingiva. This technique involves incising the gingival tissue and repositioning it apically (towards the root end).

Pocket Elimination: By moving the gingival margin apically, the procedure reduces or eliminates the depth of the periodontal pocket.

Increased Attached Gingiva: The surgery converts the unattached alveolar mucosa into attached gingiva, thereby increasing its width.

Healing: The flap is sutured at a more apical position, allowing for healing and reattachment in the new location.

The optimal flow rate of coolant for sonic and ultrasonic subgingival scaling is
1) 1-11 mL/min
2) 14-23 mL/min
3) 24-32 mL/min
4) 34-40 mL/min

πŸ“ Explanation:

Sonic and ultrasonic scalers generate heat during subgingival scaling.

A coolant (usually water) is essential to prevent thermal damage to the pulp and surrounding tissues.

The optimal flow rate ensures adequate cooling, flushing of debris, and patient comfort without excessive water spray.

Research and clinical guidelines indicate that 14–23 mL/min is the recommended range for effective cooling during subgingival scaling.

what %age of NaF is used in iontophoresis:
1.1%
2.2%
3.3%
4.4%

πŸ“ Explanation:

2% NaF is used in iontophoresis. This fluoride treatments brings about granular precipitation in dentinal tubules and reduces tubular diameter.
