A dental office is comparing three types of lasers: Laser 1 (clinically indicated negative, lower price), Laser 2 — Erbium YAG (clinically indicated positive, middle price ~$1,700), Laser 3 (clinically indicated negative, higher price). Which is most appropriate to recommend?

  1. Laser 1 — negative clinical indication, lower price
  2. Laser 2 — positive clinical indication, middle price
  3. Laser 3 — negative clinical indication, higher price
Show answer and explanation

Correct answer: B. Laser 2 — positive clinical indication, middle price

  • A. Despite the lower price, Laser 1 is not clinically indicated, making it an inappropriate choice regardless of cost.
  • B. Correct. Clinical appropriateness/indication should always take priority over price — Laser 2 is the only option that is clinically indicated.
  • C. Laser 3 is not clinically indicated and is also the most expensive option, making it the least appropriate choice.

Note: 'CI positive' = clinically indicated. Always prefer a laser that is clinically indicated, regardless of price.
