D) An unlicensed dental assistant may perform all duties of an

,Page 3 of 195
who, without a license, may perform basic supportive dental
procedures under the supervision of a licensed dentist.

they cannot perform duties restricted to licensed RDAs. The
supervising dentist is directly responsible for determining the
assistant’s competency to perform these procedures under the
dentist's supervision.

B) It has technically elementary characteristics, is completely
reversible, and is unlikely to cause a hazardous condition.
C) It involves irreversible alteration of the tooth structure.
D) It requires a minimum of two years of formal training.
Answer: B
Explanation: BPC section 1750(a) explicitly states that “basic
supportive dental procedures” are those that have technically
elementary characteristics, are completely reversible, and are
unlikely to precipitate potentially hazardous conditions for the
patient being treated.
Rationale: This definition ensures that unlicensed assistants only
perform low-risk, reversible tasks. Irreversible procedures
(placement of restorations, administration of anesthetic, etc.) are
strictly reserved for licensed professionals.
