What determines the selection of a particular periodontal instrument for a procedure?

  1. The particular color chosen for the instrument's handle coating

  3. The individual dentist's own personal preference considered alone
  4. The purchase cost of the instrument relative to the other options
Show answer and explanation

Correct answer: Location and depth of calculus, tooth anatomy, and tissue

Instrument choice depends on clinical needs — e.g., shallow supragingival deposits, deep subgingival pockets, root morphology — to ensure safe and effective debridement.
