A dental imaging room in Toronto processes forty panoramic and intraoral images a day. Each patient sits in the same chair, touches the same bite blocks and sensor holders, and produces the same saliva and blood-tinged fluid on the equipment. The imaging suite looks clean, but the consumables used between patients decide whether it actually stays clean.
Radiography has a supply profile that most dental supply checklists ignore: fewer instruments than the operatory, but higher-touch surfaces and patients who cannot keep still during a 15-second exposure. This guide covers the disposable essentials for a Canadian dental imaging suite and why each one matters for infection control and image quality.
The room runs on two consumables more than any other: 3-layer paper-PE dental bibs for every patient, and 3.5 mil nitrile exam gloves by the 1,000-glove case at the chair.
Quick facts: the four consumables an imaging room actually runs on
- Intraoral imaging puts a gloved hand in the patient's mouth and then on the exposure button, the keyboard and the next chart — the glove change between patients is the control.
- Powder-free nitrile exam gloves are the working standard: latex-free, tested to ASTM D6319, and thin enough to feel a sensor seat against the palate.
- Paper-PE bibs are single-use; a 2,000-bib case (4 × 500) covers months of normal imaging volume at a cost low enough that skipping one is never worth it.
- ASTM F2100 Level 2 or 3 masks belong in the room, because patients cough and sneeze at the moment of positioning.
- A DIN on a surface wipe means its kill claims were reviewed as a drug product; the contact time on that label is what the room's turnover has to fit.
Which gloves does dental radiography actually require?
Intraoral radiography puts the clinician's hands directly in the patient's mouth. The sensor holder and the film or digital sensor both pass through saliva, and the same hands touch the exposure button, the computer keyboard, and the next patient's chart. Powder-free nitrile gloves are the working standard for this workflow: they pass ASTM D6319 for barrier integrity, they are latex-free for the growing number of latex-sensitive patients and staff, and they give enough tactile feedback to position a small sensor without fumbling.
Imaging suites should stock gloves at the chair, not at a central station. When the box is in the room, the clinician changes gloves between every patient instead of risking a quick wipe-and-reuse. A standard 100-count box of nitrile gloves covers a busy day of imaging with room to spare.
Bibs and Barriers for Patient Protection
The lead apron is the reusable barrier that protects patients from scatter radiation, but it is also a high-touch surface that collects saliva and skin flora all day. Disposable bibs solve a related problem: they protect the patient's clothing from the saliva, blood, and contrast material that imaging patients produce, and they give the patient something clean and dry against their chest during the exposure.
Paper-PE bibs work well in imaging because they are lightweight, inexpensive, and single-use. A case of paper-PE dental bibs (4 × 500-count packs, 2,000 bibs) keeps the imaging room supplied for months of normal volume, and the per-patient cost is low enough that skipping a bib is never tempting.
Masks: Protection From the Unexpected
Patients cough during imaging. They sneeze into the sensor. They produce droplets that land on the clinician's face during positioning. Public Health Agency of Canada (PHAC) routine practices guidance for healthcare settings calls for face protection whenever splashes or sprays of body fluids are anticipated — and in an imaging room with patients of every age and health status, that anticipation is reasonable for every single exposure.
An ASTM F2100-rated surgical mask is the floor for imaging staff. Level 2 or 3 masks add fluid resistance for the moments when a patient coughs directly toward the clinician. Keep Level 3 masks in the imaging room drawer, replaced between patients.
How should imaging surfaces be disinfected between patients?
The imaging chair, the sensor holder, the exposure button, and the computer touch screen all need disinfection between patients. Hospital-grade disinfectant wipes with a DIN from Health Canada are the practical choice: they are pre-saturated at the correct concentration, they kill the organisms listed on their label within the stated contact time, and they eliminate the mixing errors that come with liquid concentrate. Choose a wipe with a DIN because Health Canada regulates disinfectants with drug identification numbers — a DIN means the kill claims have been reviewed.
Check the label for contact time before choosing a wipe for the imaging suite. A wipe that requires 4 minutes of surface contact is a different workflow commitment than one that works in 60 seconds.
Nothing in this room is high-volume; everything in it is high-touch. The table is the short version of the room checklist.
| Item | What to verify | Evidence to keep | Change point |
|---|---|---|---|
| Exam gloves | Powder-free, latex-free, examination grade | ASTM D6319 on the product documentation | Every patient, and after touching the keyboard or the chart |
| Patient bib | Paper-PE, single-use, large enough to cover the chest below the lead apron | Pack count per case (4 × 500 = 2,000) | Every patient |
| Procedure mask | ASTM F2100 Level 2 or 3 for fluid resistance | Level printed on the box | Every patient, and whenever damp |
| Surface wipe | DIN on the label, contact time that fits room turnover | DIN recorded in the procurement file | Between patients on chair, sensor holder, exposure button and touch screen |
| Sensor holder barrier | Single-use sheath, or a validated high-level disinfection step per the manufacturer's instructions | Manufacturer IFU for the holder | Every patient if the holder is not heat-stable |
What belongs in an imaging-room set-up checklist?
- Gloves at the chair, two sizes, changed between patients.
- Bibs for every patient — paper-PE is the cost-effective standard.
- Level 2 or 3 masks for aerosol and droplet protection.
- DIN-authorized disinfectant wipes for every high-touch surface.
- Sharps container for any needles used in contrast procedures.

FAQ
Does a sensor holder need a barrier if it is wiped between patients?
It depends on how the holder is classified and what its instructions for use allow. A holder that contacts oral mucosa is a semicritical item in the Spaulding scheme: heat-stable items go through sterilization, and heat-sensitive ones need high-level disinfection or a single-use barrier. Wiping with a low-level surface wipe is not the same step, so follow the holder's own instructions and keep that document with the room's infection control binder.
How many gloves does a 40-image imaging day use?
Count change points rather than patients: one pair per patient for positioning and exposure, plus a fresh pair each time the clinician touches the keyboard, the mouse or a chart mid-appointment. On a busy day that lands near two pairs per patient, so a 100-count box covers a normal day with room to spare and a second size should sit beside it.
What gloves are used for dental radiography?
Powder-free nitrile exam gloves are the standard. They pass ASTM D6319, are latex-free, and provide enough tactility to position intraoral sensors accurately.
Why do imaging patients need a bib?
Patients produce saliva and sometimes blood during imaging, and the lead apron collects skin flora and droplets all day. A disposable bib protects clothing and gives the patient a clean, dry barrier against their chest during exposure.
Are disinfectant wipes with a DIN better than ones without?
Yes for regulated claims. A DIN from Health Canada means the disinfectant's label claims have been reviewed as a drug product, so the kill claims — organisms, contact time — are verifiable. Choose wipes with a DIN for clinical surface disinfection.
How often should imaging surfaces be disinfected?
Between every patient, at minimum, on all high-touch surfaces: the chair, sensor holder, exposure button, keyboard, and touch screen. PHAC routine practices call for cleaning and disinfection of surfaces that are touched during patient care.
CliniEco Medical supplies nitrile gloves, paper-PE bibs, Level 3 masks, and DIN-authorized disinfectant wipes for Canadian imaging suites — now available for immediate order. CliniEco Medical is a licensed medical device establishment (MDEL #35334).
Bite blocks, sensor holders and the chair arm get touched between every image, and the entry that proves what was changed is often missing. The imaging suite log sheet generator keeps the per-patient record on one dated page.
An imaging room with forty images a day spends gloves and bibs on exposures rather than on patients, and panoramic days differ from intraoral days. The PPE supply planner converts exposures per week into monthly case quantities with the monthly total in CAD.
