Disposable devices in dentistry: guidelines for use

In the everyday work of a dental practice, disposable devices play a fundamental role for protecting patients, operators, and the working environment. Towels, aprons, cups, saliva ejectors, face masks, gloves, dental chair covers, and other accessories are not just consumable items, but indispensable tools for implementing clinical protocols, reducing the risk of cross-contamination, and making every operational step safer, more organized, and more efficient. 

However, the use of disposables cannot be left to routine practices. Selection, storage, usage, and disposal must follow clear and consistent criteria, based on the type of treatment, the expected level of exposure, and the person to be protected.

Disposable devices are often associated with protecting patients, operators, and surfaces from aerosols, fluids and contaminants. In fact, their value goes beyond physical protection. When chosen and managed correctly, they help standardize procedures, simplify set-up, optimize time between patients, and improve the patient’s comfort and perception of hygiene and care during treatment. For this reason, disposable products must be an integral part of the clinical protocol. Their effectiveness depends on the quality of the device, correct storage, ease of use, and adherence to the procedure to be followed. 

Not all disposable products serve the same function. Some protect the patient, some protect the operator, while others protect surfaces or the dental chair. The choice should therefore be based on the risk to be controlled. Exposure to saliva, blood, aerosols and sprays, contact with the patient’s mucous membranes or skin, contamination of surfaces, handling of materials and instruments, or the transmission of microorganisms. 

Aprons, saliva ejectors, face masks, gloves, cups, and dental chair covers are all component parts of a broader protection system. Using them correctly makes treatment safer, more organized, and more consistent with the clinical protocol. 

In order to choose the right disposable products, it is also important to understand their classification and intended use. One of the most frequent errors, in fact, is to use the terms “Medical Device” (MD) and “Personal Protective Equipment” (PPE) interchangeably, when in reality they indicate products with different functions and reference standards. 

Medical Devices are governed by Regulation (EU) 2017/745, also known as the MDR, while PPE is governed by Regulation (EU) 2016/425. A Medical Device is used for clinical purposes, such as the diagnosis, prevention, control, treatment, or mitigation of a disease. In the dental context, a Medical Device contributes to patient safety and the correct performance of the procedure. PPE, on the other hand, is primarily intended to protect the wearer from one or more health and safety risks. 

This distinction is crucial because it helps the practice to choose the most appropriate device based on the procedure, the level of exposure, and the person to be protected. Understanding the classification of a product means it can be assigned to the correct protocol, and used according to its intended purpose, and staff can be trained in a more informed way.

The safety and quality of disposable products also depends on the materials they are made from. In dentistry, the device often comes into contact with skin, mucous membranes, saliva, instruments or operating surfaces. For this reason, it must ensure adequate performance, comfort, reliability, and safety during contact. 

The main requirements to be assessed include: 

• Performance based on intended use: the material must be suitable for the function of the device, ensuring absorbency, impermeability, flexibility or barrier properties as needed; 

• Biocompatibility and contact safety: the materials must be suitable for direct or indirect contact with the skin and mucous membranes, minimizing the risk of irritation or adverse reactions; 

• Resilience: the device must maintain its performance during use, without compromising protection, functionality or comfort; 

• Comfort for the patient and operator: the product must be practical, gentle, and easy to use, without hindering clinical work; 

• Functional packaging: the packaging must protect the contents from dust and contamination, facilitate storage, and enable hygienic and controlled removal; 

• Production quality: controlled production processes and constant quality checks help to reduce handling and preserve the hygiene of the finished product; 

• Environmental impact: materials, manufacturing processes, packaging, waste reduction measures, and proper disposal all help to limit the environmental impact, without compromising the safety, hygiene, and performance of the device. 

Evaluating these aspects allows the practice to choose devices that are truly suited to their operational needs, avoiding generic solutions or those that are not consistent with the type of procedure. The quality of disposable products comes from the balance between these elements, which together make the device safe, practical, and consistent with the practice protocols. 

The correct use of disposables begins before the patient arrives. The pre-clinical phase is the time when the operator prepares the dental chair, organizes the necessary devices, and checks that every item is ready to use. 

A good protocol must be simple, repeatable, and shared by the entire team. The goal is not only to have the products available, but to arrange them in the correct order, avoiding waste, oversights, and unnecessary contact with devices that have not yet been used. 

Before each new patient, it is helpful to follow a basic operational checklist, which can be used for the daily set-up of the practice and adapted to the type of procedure planned. This may include: 

1. Cleaning and disinfection of surfaces
   Checking that the dental chair, work surfaces, and operating areas have been cleaned according to internal protocols before the new set-up;
2. Preparation of instruments
   Preparing the pouches containing the sterile instruments required for the procedure, checking that the packaging is intact and the contents are labelled correctly;
3. Patient protection
   Preparing the apron or towel according to the procedure, the duration of the treatment, and the expected level of exposure;
4. Isolation of the surgical field
   Preparing the dam and the necessary accessories when required by the procedure, to facilitate control of the surgical field, protection, and operational comfort;
5. Management of the oral cavity
   Preparing the saliva ejector or high-volume evacuator according to the procedure and the amount of fluid to be managed;
6. Cups for the patient
   Providing a new disposable cup for each patient, avoiding unnecessary handling, and not taking out more than one at a time;
7. Operator protection
   Checking the availability of the necessary protection devices, such as face masks, gloves, glasses or bandanas, based on the risk of exposure to aerosols, splashes or fluids;
8. Protection of the dental chair and surfaces
   Applying the dental chair cover, headrest cover, or barrier film to the areas that are most exposed, most frequently touched, or difficult to clean;
9. Preparation of the tray
   Preparing tray paper, Dappen dishes, and other accessories necessary for the procedure, protecting the tray from contamination and simplifying management of the workflow;
10. Final check
    Checking that instruments, devices and materials are intact, properly stored and ready for use before the patient arrives. 

For surgical or invasive procedures, the basic checklist must be supplemented with additional precautions: preparation of the sterile field, use of sterile instruments and materials, separation between sterile and non-sterile areas, adequate personal protective equipment, and organization of the tray according to the complexity of the procedure. 

One of the most underestimated moments in the handling of disposables is the removal of the device from the packaging. Touching multiple products to take just one, leaving packages open, or placing materials on unprotected surfaces can increase the risk of contamination of devices that have not yet been used. 

For this reason, it is useful to adopt controlled dispensing systems, designed to allow only one product to be taken out at a time. This is the “Single Take” principle: minimize unnecessary contact to preserve the hygiene of the device until it is used. 

A specific example is the packaging of Towel Up! Monoart, which features an ‘open/close’ system that protects the contents from dust and contamination and allows only one towel to be removed at a time, preventing contact with the next one. 

The best practices to follow are: always reclose the packaging, take the devices out wearing clean gloves, do not remove more products than necessary, do not return a device that has already been taken out to the packaging, and keep dispensers and packs in clean and protected areas. 

Fluid management is essential for keeping the surgical field clean and visible, improving patient comfort, and supporting the operator’s work. The choice between a saliva ejector and a high-volume evacuator depends on the type of procedure, the amount of fluids to be managed and the level of control required. 

A saliva ejector is recommended for daily procedures where it is necessary to remove saliva or small amounts of liquid, keeping the oral cavity drier during treatment. The high-volume evacuator, on the other hand, is better suited to procedures that generate spray, aerosols, debris, or high-volume irrigation, and therefore require a higher suction capacity. 

In both cases, the device must be chosen according to the procedure, checked before use, and positioned so as to be both stable in the oral cavity and comfortable for the patient. Incorrect positioning can reduce the effectiveness of the suction, cause discomfort to the patient, or require constant adjustment during the treatment. When using saliva ejectors, it is important to use a new device for each patient, to shape the device without applying excessive force to the fold, and to replace the device if it loses its shape, functionality or integrity. At the end of the treatment, each device must be disposed of according to its intended use and the practice protocols.

Even the simplest disposable products can be used incorrectly. Often, mistakes do not arise from carelessness, but from entrenched habits: packages left open, choosing devices not suitable for the treatment, unclear disposal procedures, or insufficient distinctions between disposable and reusable items. 

Let’s take a look at the 10 most common mistakes in the management of disposables and the measures you can take to avoid them: 

Not all disposable devices have the same function: an apron, a glove, a face mask, a cup, or a dental chair cover are used to address to different risks

Best practice: choose the product according to the procedure, the clinical risk and the person to be protected, and if necessary use an internal chart that matches procedures with their required devices. 

A disposable device is designed to be used once. Reusing a disposable item can compromise its hygiene, functionality, and safety. 

Best practice: use the device for a single patient only and dispose of it correctly after use, according to the practice’s internal protocol. 

Leaving disposable products on unprotected trolleys, worktops or surfaces can expose them to dust, aerosols, or accidental contact. 

Best practice: keep the products in their original packaging, reseal them when required, and use clean, protected dispensers. 

Taking out too many products increases the risk of waste and contamination. 

Best practice: prepare only what is needed for each procedure, following a checklist shared by the entire team. 

Using a product without knowing its function and classification can lead to inappropriate choices. 

Best practice: train staff on the difference between Medical Devices and Personal Protective Equipment and on the relevant instructions for use. 

Disposables do not simply provide protection, they also play a role in the patient experience. A poorly positioned saliva ejector, an unstable apron, or an uncomfortable cup can make the experience less comfortable for the patient. 

Best practice: choose products that combine safety, comfort, and perceived quality. 

Some areas of the dental chair or treatment room are more difficult to clean or disinfect. Neglecting these may increase the risk of indirect contamination.

Best practice: use disposable barriers and covers on the most exposed or complex surfaces.

Disposable barriers only provide protection if they are removed and replaced correctly.

Best practice: establish a procedure for removal, disposal, and reapplication between one treatment and the next.

A damaged, deformed, or poorly stored product may not provide the intended protection.

Best practice: always check the packaging and the device before use.

If each operator sets up the dental chair differently, it increases the risk of oversights, inconsistent procedures, or materials that are not suitable for the procedure. 

Best practice: create an internal procedure that outlines the set-up sequence, the products to be used, and the final checks to be performed before the patient arrives. The use of a colour-coded system can also help to distinguish workstations, treatments, or operators, making preparation more straightforward and easy to understand. 

In dentistry, safety is the result of numerous correct actions combined. Choosing the right device, storing it hygienically, taking it out correctly, using it according to protocols, and disposing of it in the right way are essential steps for reducing the risk of contamination and protecting patients, operators, and the working environment. 

Euronda Monoart disposable products are designed to support every daily practice in the dental surgery: from patient protection to operator safety, from dental chair management to tray organization. High-quality materials, functional packaging and a wide range of colours help the practice to work every day with greater safety, efficiency, and personality. 

No. A disposable device must be used only once and only for one patient. Even if it looks intact, it may have lost its hygienic or functional properties. 

If the device comes into contact with an unprotected or potentially contaminated surface, it must be discarded and replaced with a new one. 

The device must be removed and replaced immediately, checking to ensure that there are no fragments or parts of the product remaining in the work area or in the patient’s oral cavity. 

No, it is better to prepare the necessary devices for each individual patient and keep the others protected in their original packaging. This reduces waste and minimizes the risk of contamination. 

No. Disposable barriers help protect critical surfaces and areas, but they do not replace the cleaning and disinfection procedures required by practice protocols.
