What is IPAC and Why Does It Apply to Dental Offices?
IPAC stands for Infection Prevention and Control. It's a framework of protocols designed to prevent the spread of infectious diseases in healthcare settings. Dental offices are classified as healthcare facilities in Ontario, which means they fall under the same infection control obligations as hospitals and clinics.
The RCDSO publishes its Infection Prevention and Control in the Dental Office standard, which all Ontario dentists must follow. This document covers everything from instrument sterilization to surface disinfection to waste disposal. The cleaning of environmental surfaces — floors, chairs, countertops, equipment — falls squarely within these requirements.
This means your professional cleaning company is not just a service provider. They are part of your IPAC program. If they don't understand the protocols, your practice is out of compliance regardless of what they clean.
RCDSO compliance responsibility rests entirely with the dental practice owner — not the cleaning company. The College is explicit that implementation and oversight of the IPAC program rest with the principal dentist. If your cleaner uses the wrong products or the wrong procedures, you carry the finding, not them. This is why verifying your cleaning company's IPAC knowledge and documentation is not optional.
The 5 Core IPAC Cleaning Requirements for Ontario Dental Offices
1. Health Canada DIN-Registered Disinfectants
Every disinfectant used on clinical surfaces in a dental office must carry a Health Canada Drug Identification Number (DIN). This registration confirms the product has been evaluated and approved as effective against specific pathogens including bloodborne viruses.
Common DIN-registered products used in dental cleaning include intermediate-level disinfectants effective against Mycobacterium tuberculosis, HIV, and HBV. Your cleaning company must:
- Know which DIN-registered products are appropriate for each surface type
- Apply products at the correct dilution as specified on the label
- Allow the required contact (wet) time before wiping — skipping this defeats the disinfection entirely
- Use separate products for low-contact surfaces vs high-contact clinical areas where appropriate
Generic supermarket cleaners, non-DIN commercial cleaners, or diluting DIN products incorrectly are all IPAC violations — even if the surfaces look clean afterward.
2. Written Cleaning Logs
A documented cleaning routine is the evidence half of IPAC. If a complaint is investigated, a public health unit attends, or you run the College's own self-audit checklist, the records are what separate a routine that happened from one that was described. Your cleaning logs should document:
Required Cleaning Log Content
Store them where practice staff can produce them on the day they are asked for, not a week later. Retention is worth setting deliberately: the College's IPAC FAQ states that a sterilization monitoring log book must be kept for at least 10 years. Environmental cleaning logs are a separate record with no single published retention period, so your office policy sets it — two years is a common floor, and matching the sterilization retention is the conservative choice. If your current cleaning company does not provide written logs after every service, this is a significant compliance gap.
3. Dirty-to-Clean Workflow
One of the most commonly misunderstood IPAC requirements is workflow sequencing. Dental office cleaning must always proceed from cleanest zones to most contaminated — never in reverse. Here's what this looks like in practice:
Non-Clinical Areas (Start Here)
- Reception desk and front counter
- Waiting room — chairs, tables, toys, magazines
- Hallways and common areas
- Staff room and kitchen
Semi-Clinical Areas
- Consultation rooms
- X-ray rooms (non-contact surfaces)
- Lab areas (non-instrument surfaces)
- Staff offices adjacent to clinical areas
Clinical Areas (Finish Here)
- Operatory surfaces — chair, delivery unit, light handles
- Bracket tables and instrument tray areas
- Suction handles and air/water syringe handles
- Sterilization area countertops and sinks
Restrooms (Always Last)
- Toilets, urinals, and surrounding areas
- Sinks and countertops
- Door handles and high-touch surfaces
- Floors with dedicated mop (never shared with clinical areas)
Critically, mops, cloths, and equipment used in clinical zones must never be used in non-clinical zones, and vice versa. Colour-coded equipment (separate colours per zone) is the established method for preventing cross-contamination in Ontario health-care settings and the easiest one to demonstrate, because the separation is visible rather than asserted.
4. Operatory Surface Disinfection Protocol
Each dental operatory must be disinfected after every patient, but end-of-day environmental cleaning by your professional cleaning company covers the full surface inventory:
- Dental chair — all upholstered surfaces, adjustment controls, armrests
- Dental light — handles (high-touch, must use barrier or disinfect), shade, arm
- Delivery unit — all surfaces, handpiece connections, instrument holders
- Bracket table — top surface, underside, supporting arm
- Air/water syringe — handle and trigger area
- Suction handles — HVE and saliva ejector holders
- Counter surfaces — all horizontal work surfaces in the operatory
- Cabinet handles and drawer pulls — high-touch, frequently missed
- Floor — mopped with clinical-zone dedicated equipment only
This is 15–20 individual surface points per operatory. For a 4-operatory practice, that's 60–80 discrete surface disinfection steps before the clinical cleaning is complete — which is why IPAC-compliant cleaning takes significantly longer than a standard office clean.
5. Sterilization Area Cleaning
The sterilization area in a dental office is one of the highest-risk zones for cross-contamination if not cleaned correctly. The RCDSO requires strict separation of dirty and clean instrument processing. Environmental cleaning of this area must:
- Clean the dirty (used instrument) side and clean (sterilized instrument) side separately and in sequence
- Disinfect countertops, sinks, and ultrasonic cleaner exteriors
- Clean autoclave exteriors (not interiors — that's clinical maintenance)
- Disinfect all high-touch surfaces including water faucet handles
- Use dedicated cloths that are not used elsewhere in the practice
Zone-by-Zone IPAC Cleaning Protocol — Ontario Dental Offices
IPAC requirements don't apply uniformly across a dental practice. The RCDSO classifies areas by risk level, and the cleaning protocol for each zone must match that classification. A cleaning company that treats the waiting room the same as an operatory is not IPAC-compliant — regardless of how clean the practice looks.
| Zone | Risk Level | Required Disinfectant | Contact Time |
|---|---|---|---|
| Operatory — clinical surfaces Chair, light handle, bracket table, unit surfaces, doctor/assistant stools |
High — clinical contact | Intermediate-level DIN-registered disinfectant (tuberculocidal) | Per product label — typically 1–10 minutes |
| Sterilization room Instrument trays, counters, sinks, packaging area |
Critical — highest risk | Intermediate-level DIN disinfectant, dirty-to-clean workflow mandatory | Per product label |
| X-ray / imaging room Equipment surfaces, head, cone, control panel |
High | Intermediate-level DIN disinfectant compatible with equipment surfaces | Per product label |
| Washrooms Fixtures, floors, high-touch surfaces |
High | DIN-registered disinfectant — hospital-grade for fixtures | 5–10 minutes |
| Waiting room / reception Chairs, magazines/devices, reception counter, door handles |
Low-intermediate | Low-level DIN disinfectant for non-clinical surfaces | 1–2 minutes |
| Staff room / kitchen Counters, appliances, table, sink |
Low | General purpose cleaner — DIN not mandatory in non-clinical zones | Standard clean |
Colour-Coded Cleaning Equipment
Colour-coded cleaning equipment keeps clinical and non-clinical zones from sharing cloths and mop heads. It is the established practice in Ontario health-care settings and the most common thing a general cleaning company gets wrong in a dental office — either they are unaware of it, or they own the coloured buckets and use them inconsistently, which is the same failure with better props.
The standard colour-coding system used in Ontario dental offices:
- Red cloths and mops: Washrooms and toilet areas — highest contamination risk
- Yellow cloths: Clinical areas — operatories, sterilization room, x-ray room
- Green cloths: General areas — waiting room, reception, corridors
- Blue cloths: Low-risk surfaces — glass cleaning, fixtures in non-clinical areas
The colour-coding system should be documented in your written cleaning protocol — not just practiced. A written protocol is what shows the system is deliberate rather than ad hoc, and it is what a reviewer can actually read. If your cleaning company uses colour-coded equipment but cannot produce a written protocol showing which colours apply to which zones, the separation exists only in the crew's habits — which is not something you can hand to anyone.
The Written Cleaning Log
The cleaning log is the documentary evidence that IPAC protocols were followed. It is the difference between saying "we follow IPAC" and showing it — to a public health inspector responding to a complaint, to a College investigation, or to yourself when you run the RCDSO's self-audit checklist. Missing or half-filled logs are the ordinary way a real routine fails to count. Need one to start today? Use our free dental office cleaning log generator to print a ready-to-sign operatory log sheet.
A compliant dental office cleaning log must record, for every cleaning visit:
- Date and time of the cleaning
- Name of the cleaning staff member who performed the work
- Areas cleaned — specific zones, not just "office cleaned"
- Products used — product name and DIN number for each clinical area
- Disinfectant dilution — the concentration applied (where applicable)
- Contact times observed — confirmation that products were allowed to act for the required time
- Signature or initials of the cleaning staff member
The log should be kept at the practice in physical or digital form and be immediately available on the day it is asked for. Keeping at least the previous 12 months to hand is a sensible working minimum — a routine you can only evidence for the last fortnight reads as a routine that started a fortnight ago.
Every Zusashi dental cleaning visit includes a written service log documenting all of the above — date, staff, zones cleaned, products used by DIN number, and sign-off. Logs are provided to the practice at the end of each visit and can be stored in a binder at reception or forwarded digitally. Our dental clients use these logs directly for RCDSO compliance documentation.
IPAC Compliance for Specific Dental Procedures and Equipment
Beyond the standard zone cleaning, IPAC cleaning requirements interact with specific dental equipment and procedures in ways that affect what your cleaning company must know:
Dental Unit Waterlines
Dental unit waterlines (DUWLs) require regular flushing and monitoring for bacterial contamination. While waterline maintenance is typically handled by the dental team rather than the cleaning company, the surfaces around water outlets and the external components of the dental unit are cleaned by the cleaning company and must be treated with a compatible disinfectant that won't degrade tubing or fittings.
Suction and Evacuation Equipment
The exterior surfaces of suction equipment, traps, and evacuation systems are high-contamination clinical surfaces requiring intermediate-level disinfection. These are frequently missed by cleaning companies unfamiliar with dental environments — they look like generic plumbing components but are clinical surfaces under IPAC.
Portable Equipment
Portable equipment that moves between operatories — portable x-ray units, instrument trays, portable lights — requires disinfection after every use by clinical staff, and thorough disinfection by the cleaning company during the scheduled clean. Your cleaning protocol should specifically address portable equipment.
Computer Equipment in Clinical Areas
Computers, keyboards, and touchscreens in operatories are clinical-contact surfaces when used during patient treatment. They require disinfection with a product compatible with electronics — not the same intermediate-level disinfectant used on hard clinical surfaces. A cleaning company that uses the wrong product on clinical computers damages the equipment and may not achieve the required disinfection level.
Which Documents Actually Govern This — and How Current They Are
Dental IPAC guidance gets described online as if it changes every year. It does not, and knowing which document is which saves you from chasing an update that was never issued.
The binding document is the College's Standard of Practice: Infection Prevention and Control in the Dental Office. The RCDSO's own continuing-education materials describe its IPAC course as based on the Standard of Practice for Infection Control (2018), and the College's IPAC FAQ, addressing requirements for aerosol-generating procedures, notes they are "set out on page 16, and have been in place since 2018." So if you are looking for a recent wholesale rewrite of the dental IPAC Standard, there isn't one — the substance has been stable, which is good news for anyone who built a routine around it.
What has moved sits alongside the Standard:
- Public Health Ontario's checklists. PHO publishes IPAC Checklist for Clinical Office Practice — Core Elements, last updated 20 March 2024, and a companion Reprocessing checklist last updated 7 August 2019. The College's own FAQ points dentists to the Core Elements checklist, referring to it as the second edition. This is the "2024 dental IPAC document" people are usually thinking of; it is a Public Health Ontario checklist for clinical office practice, not an RCDSO standard update.
- COVID-19 guidance was withdrawn, not tightened. The College rescinded its COVID-19-specific guidance for in-person care as of July 19, 2023. That did not end the underlying obligations — screening, masking availability at reception, PPE and environmental cleaning continue under routine practice requirements and public health guidance. It simply means the pandemic-era layer is gone and the ordinary Standard governs again.
- Alignment, not divergence. The RCDSO states it works with Public Health Ontario, the Public Health Agency of Canada and PIDAC so that its IPAC Standard aligns with theirs. Where PHO's requirements and the College's Standard overlap they largely agree, though the College acknowledges some differences — which is why an office follows both rather than picking one.
One environmental point worth naming, because it is unambiguous and it is a facilities decision rather than a cleaning one: the College's IPAC FAQ states that carpeting is difficult to clean, cannot be reliably disinfected, and must not be used in clinical areas. If a treatment area is carpeted, no cleaning contract fixes that.
For the current text, read the Standard on the Royal College of Dental Surgeons of Ontario website directly rather than relying on any summary, including this one — the College's version supersedes all previous guidance and any third-party description of it.
Who Actually Checks Your IPAC Compliance
This is the part most cleaning-industry articles get wrong, including earlier versions of this one. There is no routine RCDSO IPAC walk-through of an ordinary dental office. The College states that it currently operates two inspection programs: the Dental CT Scanner Inspection Program, and the Sedation and/or General Anesthesia Inspection Program. If your practice holds neither permit, nobody from the College is scheduled to arrive and look at your cloths.
That is not the reassurance it first sounds like. The obligation is fully in force; only the arrival is unscheduled. Four things actually reach it:
- Complaints and investigations. The IPAC Standard is binding on every dentist. When a concern is raised, compliance with the Standard is what gets examined — and it is examined retrospectively, against whatever records exist by then.
- Your local public health unit. Public health units have jurisdiction to investigate IPAC complaints against individual dental offices under the Health Protection and Promotion Act, and they set requirements that mostly overlap the College's Standard but are not identical to it. If you identify an IPAC lapse in your own office, the College requires you to notify your local public health unit, which then manages the response with Public Health Ontario.
- The Quality Assurance Program. Infection prevention and control is one of the competency areas in the College's Practice Enhancement Tool, an online assessment every dentist completes five years after registration and every five years thereafter.
- Your own self-audit. The College expects offices to audit their IPAC practices and publishes a self-audit checklist for the purpose; PHO's two checklists cover the same ground. This is the only one of the four you control the timing of, which makes it the one that decides how the other three go.
Practices that do hold a sedation or CT permit get on-site College inspections and cyclical re-inspections, and those confirm compliance with the College's Standards of Practice — so for that group, an in-person review is a scheduled reality rather than a possibility.
Across all four routes, the environmental-cleaning evidence being weighed is the same short list:
- Written cleaning logs — are they current, complete, and signed?
- Disinfectant product labels — is there a Health Canada DIN, and is the product right for the surface?
- Cleaning equipment — are cloths and mops separated by zone?
- Staff knowledge — can your team explain what products are used, and the contact time?
- Written cleaning protocols — is the procedure documented, not just performed?
- The surfaces themselves — are high-touch areas actually clean?
An IPAC finding can lead to remediation requirements, conditions on a certificate of registration, or in serious cases action against the ability to practise — and a lapse also triggers a public health unit response, which is where patient notification and recall get decided. Because none of this arrives on a schedule, it is always assessed after the fact, against the records you happen to have. "Our cleaner handles it" is not an answer at that point; the protocol has to be documented and the log has to exist.
How to Verify Your Cleaning Company is IPAC Compliant
Before signing any dental cleaning contract, ask these questions directly and expect written answers:
- "What Health Canada DIN-registered disinfectants do you use, and for which surfaces?" — They should be able to name specific products immediately.
- "Can I see a sample cleaning log from another dental client?" — If they don't provide logs, walk away.
- "How do you train staff specifically for dental office IPAC?" — Generic "we train our staff" is not enough. Ask for a training outline.
- "Do you use colour-coded equipment by zone?" — This is a basic IPAC requirement. No answer or confusion is a red flag.
- "Have your logs ever been produced for a public health inspection or a College matter at a client practice?" — What you want to hear is that their records have survived somebody else reading them, not that they have never been asked.
At Zusashi Maintenance, we provide written cleaning logs after every visit, use Health Canada DIN-registered disinfectants on all clinical surfaces, and keep the documentation in a state where you can hand it over the same day it is asked for. Our dental office cleaning services are available across Toronto, Mississauga, Vaughan, Thornhill, Maple, and Newmarket.

Frequently Asked Questions
What are the IPAC cleaning requirements for dental offices in Ontario?
Ontario dental offices must follow dental IPAC practice including: daily disinfection of all clinical surfaces with Health Canada DIN-registered disinfectants, written cleaning logs after every service, dirty-to-clean workflow procedures, colour-coded equipment by zone, and staff training documentation. Implementation and oversight rest with the principal dentist, and the records are what evidence the routine if a complaint, a public health investigation or a self-audit ever calls for them.
What disinfectants are required for dental office cleaning in Ontario?
All clinical surface disinfectants must carry a Health Canada Drug Identification Number (DIN). These hospital-grade products must be used at the correct dilution with the required contact time per the product label. Generic or non-DIN cleaners are not acceptable for operatories, sterilization areas, or any clinical surfaces.
What is the dirty-to-clean workflow in dental office cleaning?
Cleaning must always progress from least contaminated to most contaminated zones — non-clinical areas first, clinical operatories next, restrooms last. Staff must never return to a clean zone after working in a contaminated one, and equipment like mops and cloths must be dedicated to specific zones and never shared across zones.
Who inspects a dental office for IPAC compliance in Ontario?
The RCDSO currently operates two on-site inspection programs — the Dental CT Scanner Inspection Program and the Sedation and/or General Anesthesia Inspection Program — so a routine, unannounced RCDSO IPAC inspection of an ordinary dental office is not how this works. IPAC compliance is enforced other ways: the College's IPAC Standard of Practice is binding on every dentist and is examined through complaints and investigations; local public health units have jurisdiction to investigate IPAC complaints under the Health Protection and Promotion Act, and a dentist who identifies an IPAC lapse in their office must notify their local public health unit; and infection prevention and control is one of the competency areas in the College's Practice Enhancement Tool, which dentists complete five years after registration and every five years after that. Practices that hold a sedation or CT permit are inspected on site, and those inspections confirm compliance with the College's Standards of Practice.
Do I need written cleaning logs for my dental office?
Yes — a documented cleaning routine is what turns "we clean the operatories" into something you can evidence to a public health unit, a College investigation or your own self-audit. Written cleaning logs should record: date and time of each clean, areas cleaned, disinfectants used (product name, DIN, dilution, contact time), and the signature of the person who performed the cleaning. The College sets a specific retention period for sterilization monitoring records — its FAQ states a sterilization monitoring log book must be kept for at least 10 years. Environmental cleaning logs are a different record with no single published retention rule, so keep them for as long as your own office policy specifies; practices commonly hold at least two years.
