The dentist is behind and tells you to seat the next patient now, but you haven't finished disinfecting the room. What do you do?

Situational · Infection control

Strong answer

Finishes the turnover to protocol, including the disinfectant's contact time from its label, before seating. Tells the dentist calmly how many minutes it needs, makes up time by having the tray and chart ready or asking a coworker to greet the patient, and raises a pattern with the practice manager.

Red flags

Seats the patient in a room that isn't finished, or cuts the contact time to keep the dentist happy.

The sterilization technician is out, so you're processing instruments between your own patients. Talk me through what happens to a used cassette until it's ready for the next tray.

Technical · Infection control

Strong answer

Carries it covered to the dirty side and puts on utility gloves, mask, eye protection and gown. Cleans, dries, inspects, packages with an indicator and labels it, runs the cycle, checks the readout and indicators, and stores it dry. Keeps dirty and clean apart and logs the load.

Red flags

Skips cleaning before sterilizing, handles sharp instruments in exam gloves, or lets clean and dirty items share a counter.

While breaking down a tray after a filling, a used explorer goes through your glove and breaks the skin. The patient is still at the front desk. What do you do?

Situational · Infection control

Strong answer

Stops, does the first aid your exposure plan lists, and tells the person who manages exposures right away, before the patient leaves, so the office can follow its plan for the source patient. Fills in the incident report and goes straight to the medical evaluation the office arranges.

Red flags

Keeps working and says nothing, or calls a small stick not worth reporting.

Say you work in a state that requires a permit to polish teeth, and you don't hold one. The dentist, running late, asks you to polish a patient's teeth while they finish next door. What do you do?

Situational · Staying in scope

Strong answer

Declines right away and respectfully, offers what they can do to help, like setting up the next room or taking the x-rays their credential covers, and tells the practice manager if it's asked again. May ask how to earn the permit if the office wants that duty.

Red flags

Polishes anyway because the dentist asked, or doesn't know which duties need a permit.

Walk me through the duties you did at your last office that needed a state credential, and which credential covered each one.

Technical · Staying in scope

Strong answer

Names each regulated duty they did, such as x-rays, polishing or sealants, with the certificate or registration that covered it and when it renews. Names the state dental board, or DANB's state lookup, as where they'd check.

Red flags

Did regulated duties without knowing whether they needed a credential, or can't say what they hold.

A patient who canceled twice is finally in your chair for a filling. Their hands are shaking, and they tell you the last dentist didn't stop when they asked. What do you do before the dentist walks in?

Situational · Calming patients

Strong answer

Listens and says the fear makes sense, explains what will happen, and agrees on a stop signal the dentist will honor. Briefs the dentist before they walk in, offers the comfort measures the office uses, and notes what helped in the chart for next time.

Red flags

Tells them to relax, or says nothing to the dentist.

Tell me about a crown or denture visit where the lab case wasn't ready, or nearly wasn't. How did you learn about it, and what happened?

Behavioral · Follow-through

Strong answer

Red flags

Found out with the patient in the chair and blames the lab or the front desk.

Behavioral · Follow-through

Strong answer

Walk me through a full periodontal charting from start to finish, and how you make sure the numbers are ones the next hygienist can trust.

Technical · Accurate assessment

Strong answer

Charts every site and records every finding the dentists' protocol lists, such as pocket depths, bleeding and recession, the same way each time. Compares with past charts and current images, brings changes to the dentist with readings and photos, and leaves the diagnosis to the dentist.

Red flags

Charts only the problem areas, fills in from memory, or skips charting when behind.

At a recall visit, the patient mentions a new medicine and a hospital stay since last time, but their health history form says 'no changes.' What do you do before any treatment begins?

Situational · Accurate assessment

Strong answer

Updates the history with the patient, recording the medicine by name and the reason for the stay. Brings it to the dentist before any treatment and waits for the dentist's direction under the office protocol. Documents what was found and decided, and doesn't advise the patient about the medicine.

Red flags

Goes by the form, or starts treatment without telling the dentist.

Your charting shows the patient's gums are worse than last year. The dentist recommends deeper gum treatment, and the patient says insurance won't cover it, so they'll just have the regular cleaning. What do you say?

Situational · Patient education

Strong answer

Shows the chart and photos, explains in plain words what has changed and what could happen without treatment, and brings in the treatment coordinator for cost questions. Respects the patient's choice, does what the dentist approves for today, and records the recommendation and the refusal.

Red flags

Offers fixes there and says plainly they'll recommend only what the findings and the dentist support.

Red flags

Agrees to push services to hit the number, or waves off the numbers entirely.

The dentist has left the building for lunch. Your next patient is booked for gum treatment and asks you to numb them and start now so they can get back to work. What do you do?

Situational · Working with the dentist

Strong answer

Knows which duties need the dentist present under state rules and office protocol. If the anesthesia or treatment needs the dentist there, doesn't start, explains kindly, and offers to begin what's allowed or the earliest time the dentist is back. Tells the practice manager.

Red flags

Starts because the patient asked, or doesn't know their state's supervision rules.

Tell me about a time one of your chart notes was questioned, by a dentist, an insurance company or an audit. What happened?

Red flags

Can't name one, blames the software or the dentist, or edited the old note to cover the gap.

Tell me about a day your hygiene schedule fell apart, like a late patient, a long gum treatment or a coworker out sick. What did you do?

Think of a patient whose gums got healthier after you changed the way you coached them on home care. What did you change?

Behavioral · Patient education

Walk me through placing a Class II composite after the dentist prepares the tooth.

Technical · Restorative technique

Strong answer

Isolates the tooth, such as with a rubber dam, places matrix and wedge, follows the product's bonding steps, places and cures in layers as the material requires, shapes contacts and anatomy, checks the bite, and has the dentist check it.

Red flags

Skips isolation, places it in one bulk layer when the product doesn't allow it, or dismisses the patient before the dentist checks.

While you're placing a composite, isolation fails and saliva gets on the bonded surface. What do you do?

Situational · Handling contamination

Strong answer

Stops, re-isolates, cleans the surface, and repeats the bonding steps as the manufacturer directs before placing material.

Red flags

Dries it off and keeps going.

The dentist is behind and asks you to adjust a crown prep margin so the impression can be taken. What do you do?

Red flags

Does it because the dentist asked.

Writes only the procedure name.

The spore test for one sterilizer comes back positive. What do you do?

Situational · Failed spore tests

Strong answer

Takes the sterilizer out of use, tells the practice manager right away, checks loading, packaging and cycle settings, and retests. If it fails again, keeps it out until repaired and recalls and reprocesses items from loads since the last good test.

Red flags

Retests and keeps using the sterilizer in the meantime.

Walk me through what happens to an instrument from the moment it leaves the operatory until it's back on a tray.
