During a composite resin restoration, what is the dental assistant's primary responsibility when the dentist is etching the tooth surface?
Answer: Preparing the bonding agent for application
While the dentist applies the etchant, the assistant should have the bonding agent ready for immediate application after rinsing and drying, maintaining an efficient workflow.
Which suction technique is most appropriate when assisting during a surgical extraction in the mandibular posterior region?
Answer: Surgical suction tip positioned at the retromolar area with intermittent activation
A surgical suction tip positioned at the retromolar area allows controlled fluid removal without obstructing the surgeon's view, and intermittent activation prevents tissue trauma.
When preparing a tray setup for a root canal procedure, which instrument would NOT typically be included in the initial access kit?
Answer: Lentulo spiral paste filler
A Lentulo spiral paste filler is used during the obturation phase to place sealer into the canal, not during the initial access opening stage of root canal treatment.
What is the correct mixing time for zinc phosphate cement when used as a luting agent for a permanent crown in Canadian dental practice?
Answer: 60-90 seconds incorporating small increments on a cool glass slab
Zinc phosphate cement requires gradual incorporation of powder into liquid over 60-90 seconds on a cooled glass slab to control the exothermic reaction and achieve optimal working properties.
During a four-handed dentistry procedure, the assistant is using the transfer zone technique. Where should instrument transfers occur relative to the patient?
Answer: Below the patient's chin at the transfer zone
The transfer zone in four-handed dentistry is located below the patient's chin, preventing instruments from being passed over the patient's face, which is both safer and less anxiety-inducing.
When assisting with an alginate impression of the maxillary arch, what should the assistant do immediately after the dentist seats the loaded tray?
Answer: Retract the patient's lip to check tray margins and support the tray if needed
After tray seating, the assistant should check that the tray margins are properly positioned, retract soft tissues if needed, and be ready to support the tray to prevent movement during the setting time.
