Answer: 2
Antihistamines are not typically associated with significant effects on
periodontal therapy. In contrast, propranolol (a beta-blocker), sodium warfarin
(an anticoagulant), and corticosteroids can all influence periodontal health and
treatment outcomes.

Which of the following flap technique does not eliminate pocket depth and hence cannot increase the width of keratinised gingiva
1) Modified Widman flap
2) Undisplaced flap
3) Apically displaced flap
4) All of the above
Periodontics
Answer: 1
The Modified Widman flap is designed for access to the root surface for debridement without significantly altering the pocket depth or increasing the width of keratinized gingiva. Other techniques, such as apically displaced flaps, aim to modify the gingival architecture.
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.

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.
