Type of incision for periodontal surgery mainly depends on 
 1. Depth of vestibule
 2. Frenal attachments

#3 Periodontics
Subgingival scaling is performed below the gum line, where direct visualization is limited or impossible.

Clinicians rely on the feel of the instrument against the tooth/root surface to detect calculus, plaque, or irregularities.

Visual inspection with a mirror is useful for supragingival areas but not effective subgingivally.

Radiographs can show bone levels and some calculus deposits but are not sufficient for precise scaling.
Tap for Question
Answer
The area where subgingival scaling is performed is often described as an invisible working area. What does the clinician primarily rely on in this area? 
1) Visual inspection with a mirror.
2) Radiographic interpretation.
3) Tactile sensitivity.
4) Patient feedback on pain levels.

#8 Periodontics
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.
Tap for Question
Answer
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
