How do you probe?
Hold side probe tip flat against the tooth surface, probe parallel to long axis of tooth for vertical insertion. Slide probe vertically down to base of pocket, maintain contact to side of tooth using a walking stroke, and count mm that show the probe on gingival margin and subtract from total number.
How can you detect calculus other than with an explorer?
Disclosing Solution and Compressed Air

What’s the difference in Supragingival and Subgingival Scaling?
Supragingival Scaling: Coronal to Gingival Margin
