- The cutting edge should be used for calculus removal with the specific curet described.
Calculus Detection
- Supragingival calculus is located above the gingival margin and can appear yellow, brown, or black.
- Subgingival calculus is located below the gingival margin and appears brown or black due to the presence of hemin.
- Supragingival calculus is detected by visual examination and tactile sensation.
