Why transferring radiography films dry with a paper towel is essential for clean, artifact-free images

Film handling in dental radiography isn’t flashy, but trust me, it’s the quiet hero of clean images and safe care. When you snap a radiograph, you’re not just chasing a perfect picture—you’re protecting patient safety, curbing the spread of germs, and ensuring the film produces a clear, diagnostic result. The way you handle films during exposure makes all the difference. So, let’s unpack the essentials, keep it practical, and keep the science simple.

Why film handling even matters

You might be wondering, what’s so delicate about a little film? The answer is moisture, oils, and dust. A damp finger, a stray breath of humid air, or a speck of dust on the film surface can create artifacts—unwanted marks that masquerade as real anatomy or mask problems that matter. In other words, a sloppy handoff can lead to a misread diagnosis, which isn’t just a professional slip-up—it can affect patient care.

On the infection control side, radiographs travel through a lot of hands and surfaces. Even though films themselves don’t pass through a saline bath, they do touch gloves, paper towels, barrier envelopes, and the occasional sterile tray. If moisture or contaminants ride along, you risk contamination and compromised image quality. The simplest, most reliable safeguard is to handle films in a way that minimizes contact with anything that could transfer moisture or grime.

The right move: transferred dry with a paper towel

Here’s the be-true moment: the correct method is to transfer the film dry with a paper towel. Why a paper towel? It’s a clean, absorbent barrier that helps keep moisture away from the film’s surface. A dry transfer reduces the chance of water marks, smudges, and other contaminants that could steer your diagnostic eye wrong. And yes, using a dry paper towel is also kinder to the film—moisture and film don’t mix well, and moisture can alter the surface in ways you don’t want to see on the image.

Think of it this way: you’re the steward of two things at once—your patient’s safety and the fidelity of the radiographic image. The paper towel is your lightweight shield, simple but effective, like a tiny barrier that quietly does its job so you don’t have to fight a cloud of artifacts later on.

How to handle films during exposure: a practical walkthrough

Let me explain a straightforward approach you can adopt without added fuss:

• Prep the space and your gear

• Have a clean, dry workspace. A towel-lined tray or a barrier-wrapped surface works well.

• Keep a dry paper towel within easy reach. You want to avoid hunting for towels mid-procedure.

• Wear gloves as dictated by your infection control protocol, and change them if they become contaminated.

• Approach the film with intention

• Hold the film by its edges, not the surface. Edges stay clean, surface stays pristine.

• If the film is in a barrier envelope, remove the envelope carefully, letting the film remain dry and undisturbed.

• If you must touch the film, do so with dry hands or gloves that are clean and dry. Avoid grabbing the center surface.

• Transfer the film neatly

• Place the film on the prepared surface and, with a dry paper towel, lift or slide it as needed—never yank or twist. The idea is to minimize contact with the film’s active surface.

• If you need to reposition a film, do it gently and keep it away from moisture sources like damp towels or condensation.

• After exposure, set it down and proceed

• Once the exposure is complete, set the film on a clean, dry area or into its designated processing tray using the same dry-hand technique.

• If your workflow includes barrier envelopes or protective holders, close or seal them promptly to keep the film surface clean during transit.

• Always align with your clinic’s infection control guidelines

• The exact steps can vary a bit depending on local policies, whether you’re using film in a cassette system or a digital-to-film workflow, and the specific materials your team uses. The principle remains: keep moisture away, avoid surface contaminants, and handle by the edges.

Common missteps that can bite you later

It’s worth naming the slip-ups so you can sidestep them:

• Handling films with bare wet hands

• Water on the film surface dries into marks and can interact with chemical developers during processing. It also increases the risk of cross-contamination.

• Exposing the film to air for long periods

• Air brings dust, humidity, and sneaky microbes. Catch the film quickly, move it to the next station, then clean up.

• Touching the active surface

• Fingerprints and oil from skin can alter the surface and produce artifacts that mimic real structures.

• Skipping a dry-paper-towel step

• Skipping this small barrier step is like skipping a seatbelt—you might not feel the risk right away, but the consequences can be messy.

The bigger picture: image quality and patient safety

You might be tempted to treat film handling as a routine chore, but there’s real science behind it. Clear, artifact-free radiographs are the backbone of accurate diagnosis. When films are kept dry and clean, the radiologist or dentist sees what’s truly there: bone levels, tooth structure, pathologies, and alignment. That accuracy directly informs treatment plans—whether you’re planning a root canal, a crown, or a simple cleaning.

From an infection control perspective, disciplined film handling protects everyone in the clinic. It minimizes cross-contamination, reduces the chance of spreading bacteria through shared surfaces, and respects the patient’s comfort and trust. People notice when a clinic runs like clockwork, with clean trays, dry hands, and steady hands. It’s a confidence booster for patients and a professional boost for you.

A few extra tips you might find handy

• Use barrier envelopes when available

• If your system uses film barriers, keep them intact until you’re ready to expose. They add an extra layer of protection against moisture and smear.

• Keep a consistent workflow

• A predictable sequence—set up, expose, transfer dry with paper towel, and move to processing—reduces the chance you’ll skip a safety step in the heat of the moment.

• Train with a buddy

• It helps to practice these steps with a partner. A quick check from a colleague can catch a moisture lapse or a mis-handled film before it becomes an issue.

• Remember the human factor

• It’s easy to treat these tasks as mechanical, but they’re about people—the patient in the chair, the dental team, and the broader community relying on safe care. Let that be a motivator for careful, deliberate handling.

Connecting the dots: why this is a foundational habit

You wouldn’t drive a car without wearing a seatbelt, right? Handling films dry with a paper towel is a similar safety habit. It’s simple, repeatable, and profoundly effective. It doesn’t require fancy gadgets or heroic maneuvers. It’s about keeping things clean, dry, and straightforward so you can concentrate on what really matters: capturing a high-quality image that informs care.

If you’re building a routine around infection control in dental radiography, think of film handling as a keystone. It pulls together two critical threads: the science of imaging and the ethics of patient care. When you get this right, you’re not just taking pictures—you’re contributing to safer clinics, clearer diagnoses, and better outcomes for every patient who sits in your chair.

A quick, friendly recap

• The correct method for handling films during exposure is to transfer them dry with a paper towel.

• Moisture and oils can ruin image quality; a dry transfer minimizes artifacts.

• Always handle films by the edges and on a clean, dry surface.

• Use barrier envelopes when possible, and follow your clinic’s infection control guidelines.

• Practice the steps with a colleague to ensure consistency and safety.

If you’re curious about the little details that make this work in real clinics, you’ll find that many teams combine these basic habits with smart workflow choices—barrier systems, dedicated radiography stations, and quick-reference reminders posted near the work area. It all adds up to a calmer, safer, and more reliable imaging process.

Now, go ahead and give your next radiography session this steady, dry-hand approach. You’ll notice the difference in both the image quality and the sense of confidence you bring to patient care. And in the end, isn’t that what good dental radiography is all about—clear pictures, clean hands, and care that sticks.
