What You Need to Know About Infection Control Standards in Dental Construction

When constructing or upgrading a dental clinic in Canada, infection control is perhaps the most crucial aspect to keep in mind. It’s not merely about having your clinic appear up-to-date—it’s about providing a safe, sanitary environment that guards both patients and professionals. With regulations on health becoming stricter, knowing infection control measures in dental buildings is more vital than ever before.

From smart layouts to air filtration systems and easy-to-clean surfaces, following proper guidelines helps your clinic stay compliant and build trust with every patient who walks through the door. In this blog, we’ll break down the most important standards, explain what they mean, and show how to apply them during your clinic’s construction or renovation process.

Overview of Infection Control Standards in Dental Construction

Designing or building a dental clinic isn’t so much about design as it is about fulfilling rigorous infection prevention standards that safeguard everyone in the facility. In Canada, infection control standards during dental construction rely on best practices from bodies such as IPAC Canada, the CDC (Centers for Disease Control and Prevention), and provincial regulatory agencies such as the RCDSO (Royal College of Dental Surgeons of Ontario) in Ontario.

IPAC Canada and Provincial Guidelines

Infection Prevention and Control (IPAC) guidelines are explicit in dental offices. The Royal College of Dental Surgeons of Ontario (RCDSO) in Ontario specifies strict standards for sterilization rooms, hand hygiene stations, ventilation, and surface materials. These standards direct the physical layout and workflow of new or reconstructed dental clinics to minimize cross-contamination risk.

CDC Best Practices for Dental Settings

CDC’s Summary of Infection Prevention Practices in Dental Facilities is commonly cited throughout North America. It describes critical features such as proper sterilization areas, clean-to-dirty flow for equipment processing rooms, hand-hygiene sink location, and air control to minimize aerosol transmission. Although the CDC is not a Canadian agency, its guidelines frequently supplement Canadian requirements and are best practice during design. 

Canadian Dental Association Recommendations

The Canadian Dental Association (CDA) also offers general infection control recommendations, emphasizing environmental cleanliness, barrier protection, and patient safety. While not as regulatory as IPAC or provincial authorities, CDA guidelines are an important component of a compliant, patient-safe building plan.

Briefly, in order to serve infection control needs today, dental clinics have to be designed with specific zoning, air exchange, sterilization process flows, and surface selections in mind. Being up to code equals safer care, less risk, and reduced anxiety for both dentists and patients.

Design & Construction Considerations for Compliance

In order to achieve infection control in dental building, careful planning of the construction and designing process is required from the ground level. Compliance cannot be retrofitted afterwards—it must be integrated into the very foundations of your clinic, both physically and strategically. The following are the key design elements that ensure your dental clinic is not only safe but also completely compliant with Canadian and provincial infection control recommendations.

1. Workflow & Layout Planning

Creating a layout that is divided between clean and contaminated areas is one of the initial compliant dental clinic design steps. This involves specific sterilization rooms with a “clean-to-dirty” flow, ideal hand hygiene station placement, and patient/operator traffic lanes that minimize cross-contamination.

Sterilization areas should be positioned centrally and apart from treatment zones.

Handwashing sinks are to be placed conveniently in each operatory and at points of entry.

Waiting areas must accommodate physical distancing and have barriers where necessary.

2. Surface & Material Selection

Surfaces that are used throughout the clinic need to be smooth, non-porous, and easy to clean with a disinfectant. This prevents bacterial growth and enables frequent cleaning without damaging the surface.

Flooring needs to be coved (curved where the floor meets the wall) to eliminate joints that are difficult to clean.

Countertops need to be resistant to strong disinfectants—quartz, Corian®, and medical-grade laminate are best.

Walls in treatment spaces must be finished with scrubbable, antimicrobial paint or PVC panels.

3. HVAC & Aerosol Management

Air quality control is important for preventing infection, particularly in the treatment rooms where aerosol-generating procedures are performed. Investment in upgrading your HVAC system will go a long way in minimizing airborne risks.

Install HEPA filtration devices and maintain suitable air exchange rates per room.

Negative pressure rooms may be considered for surgical or high-risk procedures.

Add UV-C light systems in ducts to eliminate airborne pathogens.

4. Plumbing & Fixtures

Plumbing design should also facilitate infection control. Wherever possible, touchless technology is encouraged to avoid contact and limit germ transmission.

Utilize sensor-activated faucets and soap dispensers in all washrooms and operatories.

Install backflow prevention valves on all waterlines.

Design specific waterline flushing stations to avert contamination problems within dental units.

Equipment, Sterilization & Device Protocols

A vital part of meeting infection control standards in dental construction is how your clinic handles sterilization and medical equipment. Proper design supports daily cleaning routines and ensures that your tools, rooms, and workflows meet both Canadian and international standards for dental safety. This section focuses on setting up equipment zones and protocols that align with IPAC, RCDSO, and CDC recommendations.

1. Sterilization Room Design & Equipment Flow

Your sterilization area needs a “dirty-to-clean” workflow. Used instruments should have a well-defined path—from receiving and cleaning to sterilization and storage—without reversal.

Create isolated zones: receiving, cleaning, packaging, and storage

Install under-counter ultrasonic cleaners and automated washers to minimize manual handling

Use Class B autoclaves (or equivalent) with logs to satisfy provincial documentation standards

Provide for proper ventilation in sterilization rooms to avoid moisture accumulation and bacterial growth

2. Safety of Medical Devices and Licensing

All equipment that is employed in a dental office—particularly equipment that comes into contact with mucous membranes—needs to be approved by Health Canada and well maintained. Dental chairs, x-ray machines, and autoclaves should be set up in accordance with manufacturer and provincial compliance standards.

License devices as Class I–III under Health Canada regulations

Maintain equipment maintenance records and sterilizer validation records (biological, chemical, and mechanical indicators)

Provide a decontamination space for any reusable dental equipment or accessories

3. Waterline Maintenance & Aerosol Management

Dental unit waterlines (DUWLs) can be an avenue of bacterial contamination if not regularly cleaned and maintained. Design should incorporate elements that facilitate this to be done more easily.

Utilize built-in waterline treatment systems and integrate quick-disconnect valves

Implement flushing protocols and shock treatments as part of regular maintenance

For aerosol-dense procedures, add high-volume evacuation (HVE) and extraoral suction units

4. Safe Storage & Accessibility

Sterilized equipment needs to be stored in covered, labeled cabinets distant from splash areas or foot traffic. Easy access for sterilized instruments without exposing them to contamination should be included by each operator.

Create clean storage areas with a low amount of open shelving

Don’t put sterilized materials in shared traffic streams or under sinks

Utilize touchless cabinet systems where practical to minimize contact

Operational Best Practices in Construction and Aftercare

More than physical design alone, meeting infection control standards in dental construction also addresses how your clinic is operated and maintained once construction is finished. From personnel training to scheduled inspections, all practices should maintain uniform routines for becoming and staying compliant, clean, and patient-safe over time.

1. Staff Training & Education

One of the most important areas of continued infection control is making certain that your staff knows and adheres to all procedures properly. All members of staff must be trained on both the physical layout of the clinic and the infection control procedures associated with it.

Designate an IPAC Coordinator to ensure compliance and provide regular updates

Provide mandatory infection control orientation on initiation and an annual refresher thereafter

Provide clear SOPs (standard operating procedures) for cleaning, PPE use, and instrument sterilization

This not only keeps your practice compliant with RCDSO and IPAC guidelines but also protects your staff and builds patient trust.

2. Regular Audits & Self-Assessment

Once your clinic is up and running, staying compliant requires ongoing review. Many provinces, including Ontario, recommend or mandate self-audits for infection prevention.

Use the RCDSO IPAC self-audit tool or similar provincial checklists

Organize monthly reviews of sterilization logs, PPE inventory, and cleaning reports

Write down all inspections and updates for accountability and transparency

Biological indicator tests (spore testing) should be done once a week and recorded for validation

Having proper documentation will not only assist in case of an inspection but also maintain day-to-day procedures consistent and safe.

3. Personal Protective Equipment (PPE) Management

Having proper PPE on hand—and utilizing it properly—is a basic component of infection control. In planning construction, PPE storage and access must be incorporated into the clinic design.

Design separate PPE storage cabinets in proximity to operatories and sterilization areas

Provide disposal units for masks, gloves, gowns, and face shields in all clinical areas

Keep a supply of CSA- and Health Canada-approved PPE and make sure to rotate and replenish it regularly

4. Aftercare Maintenance and Support

Even a well-designed dental clinic, equipment, surfaces, and systems all require ongoing maintenance. Designate a maintenance routine involving all major systems that have to do with infection control.

Schedule HVAC filter changes, waterline treatments and equipment calibration

Maintain logs for cleaning high-touch areas such as reception counters, doorknobs and shared tech
