periodontics - 3 Questions

1
Periodontics
The outcome of results of laterally positioned flap depends on 
 1. Presence of sufficient bone support at donor site
 2. Thickness of attached gingiva at donor site
 3. Width of attached gingiva at donor site
 4. All of the above

πŸ“ Explanation:

The success of a laterally positioned flap procedure, which is a type of periodontal plastic surgery used to cover exposed root surfaces, relies on several factors related to the donor site. 

Sufficient bone support: Adequate bone at the donor site is crucial to ensure the stability and blood supply of the flap after it is moved to the recipient site. 

Thickness of attached gingiva: A thicker flap generally has a better blood supply and is more resistant to tearing and recession, leading to a more predictable outcome.
 
Width of attached gingiva: Sufficient width allows for proper mobilization and positioning of the flap without tension, which is essential for successful integration and healing.

Periodontics
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

πŸ“ Explanation:

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.

1. contains fibrous bone
2. follows the slope of the adjacent cementoenamel junctions
