As of July 2026, the standards governing dental sterilization in Canada remain among the most rigorous in the world. The Royal College of Dental Surgeons of Ontario (RCDSO), the Provincial Infectious Diseases Advisory Committee (PIDAC), and Health Canada collectively set the framework that every dental practice in Ontario must follow. Meeting those standards starts with having the right supplies — and understanding how each component of the sterilization workflow contributes to patient safety.
Understanding the Dental Sterilization Workflow
Before diving into specific supplies, it helps to understand the full instrument reprocessing cycle. Every reusable dental instrument follows this path after patient contact:
Each stage requires specific supplies. Getting the right products — and understanding why each matters — is the difference between a compliant, efficient sterilization centre and one that exposes your practice to risk.
Sterilization Pouches: Your First Line of Sterile Barrier Defence
Sterilization pouches are the single-use packaging systems that maintain instrument sterility from the moment the autoclave cycle ends until the moment the instrument is needed chairside. A standard pouch features medical-grade paper on one side (which allows steam or chemical vapour to penetrate during sterilization) and transparent plastic film on the other (which lets you visually confirm contents without opening).
Class 4 Pouches: The Standard for Canadian Dental Practices
Class 4 sterilization pouches contain a multi-variable chemical indicator printed directly on the pouch. Unlike a simple Class 1 indicator (which only confirms exposure to heat), a Class 4 indicator reacts to at least two critical sterilization variables — typically time and temperature. When the indicator changes colour completely, it confirms that the contents were exposed to conditions consistent with sterilization.
EBIKO Dental stocks Sterilization Pouches Class 4 in six sizes (200/pk), covering everything from small hand instruments like explorers and carvers to larger items like extraction forceps and surgical elevators. Having the right size matters: an oversized pouch wastes autoclave space and can fold over on itself, potentially blocking steam penetration. An undersized pouch risks instrument tips puncturing the paper barrier.
Pro Tip: Stock at least three pouch sizes for a general practice: 2.25" x 8" for hand instruments and burs, 3.5" x 10" for scalers, curettes, and composite instruments, and 5.25" x 10" or larger for forceps and surgical kits. This covers 90% of your packaging needs without overstocking.
Pouch Loading Best Practices
Proper pouch loading is where many practices introduce unnecessary risk. Follow these guidelines:
- Fill to 75% capacity. Overpacking prevents steam from circulating around instruments, which can leave cold spots where sterilization is incomplete.
- Open all hinged instruments. Hemostats, needle holders, and scissors should be loaded in the open position so steam contacts all surfaces.
- Place instruments so they do not puncture the pouch. Sharp tips should point away from the paper side. For pointed instruments like explorers and endodontic files, consider placing a small cotton roll over the tip before sealing.
- Seal pouches completely. Whether using self-seal adhesive strips or a heat sealer, verify the seal has no gaps. A compromised seal means the pouch cannot maintain sterility after the cycle.
- Write the date and sterilizer cycle number on the pouch using a non-toxic marker on the plastic side. This creates traceability — if a biological indicator fails, you can identify which pouches from that cycle need to be recalled and reprocessed.
Chemical Indicators: Verifying Every Cycle
Chemical indicators are colour-changing strips or inks that respond to sterilization conditions. They are classified by the Canadian Standards Association (CSA) and ISO standards into six classes, but dental practices primarily use three:
Class 1 — External Process Indicators (Autoclave Tape)
Autoclave tape is the most basic indicator. It changes colour (typically from beige to dark brown/black stripes) when exposed to heat, confirming that the pack went through a sterilizer. It does NOT confirm sterilization was achieved — it only tells you the item was processed. Think of it as a "been in the autoclave" flag.
EBIKO Dental carries Autoclave Sterilization Tape in three sizes. Use it to seal CSR-wrapped packs and to identify unprocessed versus processed items at a glance.
Class 4 — Multi-Variable Indicators
Class 4 indicators are built into EBIKO's sterilization pouches and react to at least two sterilization parameters (time and temperature). They provide a higher level of confidence than Class 1 tape. When you see the indicator stripe on a pouch change completely, it means the conditions inside that pouch were consistent with sterilization parameters.
Class 5 — Integrating Indicators
Class 5 integrating indicators are the gold standard of chemical monitoring. They respond to all critical parameters of the sterilization cycle — time, temperature, and the presence of steam — and their performance is designed to correlate with the kill conditions for biological indicators (spore tests). A fully changed Class 5 strip provides the highest chemical assurance that sterilization was achieved.
EBIKO Dental stocks Chemical Integrator Indicators — Class 5 (200/pk). Place one inside a pack or pouch with each load. The RCDSO recommends using internal chemical indicators (Class 4 or higher) in every package.
Pro Tip: Place the Class 5 indicator strip in the centre of the most challenging pack in the load — the largest, densest package that is hardest for steam to penetrate. If the indicator passes in the most difficult position, you have strong confidence the rest of the load was sterilized effectively.
CSR Sterilization Wrap: For Larger Instrument Sets
Not everything fits in a pouch. Surgical trays, cassettes, and large instrument sets require sterilization wrap — also called CSR (Central Supply Room) wrap. This medical-grade fabric allows steam to penetrate while maintaining a sterile barrier after processing.
EBIKO Dental offers CSR Sterilization Wrap in five sizes, accommodating everything from small cassettes to full surgical tray setups. The wrap should be applied using a sequential double-wrap technique (two layers, each folded with the corners tucked in) to create a reliable sterile barrier that can be opened aseptically chairside.
Seal wrapped packs with autoclave tape, which serves double duty: it holds the wrap closed and provides a Class 1 process indicator confirming the pack was processed.
Sterilization Cassettes: Organizing for Efficiency and Safety
Instrument cassettes keep instruments organized throughout the entire reprocessing workflow — from chairside to ultrasonic to autoclave to storage. They reduce the risk of sharps injuries (no loose instruments to handle), improve autoclave loading efficiency, and ensure instrument sets are complete before the next procedure.
EBIKO Dental carries sterilization cassettes in multiple configurations:
- 7-instrument cassette (200x90x32 mm) — ideal for basic exam setups
- 8-instrument cassette with accessory area (202x140x30 mm) — fits composite or scaling setups
- 12-instrument cassette with accessory area (165x267x32 mm) — for surgical or perio kits
- 14-instrument double-decker cassette (114x203x38 mm) — maximum capacity for comprehensive procedure trays
All EBIKO cassettes feature detachable lids and are compatible with CSR wrap or extra-large sterilization pouches. For cassettes holding mixed instruments, use Hinged Instrument Clips to secure each instrument in place during ultrasonic cleaning and autoclaving.
Surface Barriers and Disinfection: The Other Half of IPAC
Sterilization covers reusable instruments. But operatory surfaces, equipment handles, light switches, and chair controls also require protection. This is where surface barriers and disinfectants complete the IPAC picture.
Surface Disinfectants
Canadian dental practices must use Health Canada DIN-registered surface disinfectants. EBIKO Dental carries several options to match your practice's workflow preferences:
- Micrylium BioSURF Hospital-Level Surface Disinfectant — a Canadian-made, hydrogen peroxide-based disinfectant with a broad-spectrum kill claim and no harsh chemical residue. Available in multiple formats.
- Micrylium BioTEXT Surface Disinfectant — another Micrylium formulation optimized for dental operatory surfaces.
- OPTIM 33TB Disinfectant Wipes (160/pack) — AHP (accelerated hydrogen peroxide) wipes widely used in Canadian dental offices for their compatibility with sensitive equipment surfaces.
- Micrylium BioTEXT Surface Disinfectant Wipes — pre-saturated wipes for fast operatory turnover.
- CaviWipes Surface Disinfectant Wipes — a widely recognized quaternary ammonium/alcohol-based wipe.
- CaviWipes 2.0 XL (65/canister) — extra-large format for covering chair arms, countertops, and larger surfaces in fewer passes.
Pro Tip: When choosing between spray-and-wipe disinfectants and pre-saturated wipes, consider your operatory turnover speed. Pre-saturated wipes are faster and ensure consistent saturation, while spray-and-wipe systems are more economical for large surface areas. Many practices use both — wipes for quick turnovers, spray for end-of-day deep cleaning.
Surface Barriers
Barrier film covers surfaces that are difficult to clean or disinfect between patients — light handles, x-ray heads, control panels, and bracket trays. EBIKO Dental offers Barrier Film 4"x6" (1200/roll) with an easy-peel adhesive backing, plus a dedicated Barrier Film Dispenser for one-handed application during operatory setup.
Additional barrier products for specific equipment:
- Digital Sensor Sleeves (500/pk) — three sizes for intraoral digital x-ray sensors
- Air Water Syringe Sleeves (500/pk)
- Curing Light Sleeves (500/pk)
- Handpiece Sleeves (500/pk)
- Ultrasonic Scaler Sleeves (500/pk)
- Intra Oral Camera Sleeves (100/pk)
- Light Handle Sleeves T-Style (500/pk)
- Light Guide Sleeves (200/pk)
- Bite Block Covers (500/pk)
Autoclave Loading: Maximizing Efficiency Without Compromising Safety
Even the best supplies fail if the autoclave is loaded incorrectly. Follow these principles:
- Do not overload. Packs and pouches need space between them for steam to circulate. A tightly packed autoclave looks efficient but produces unreliable sterilization.
- Place pouches on edge, paper side to plastic side. This allows steam to enter through the paper and escape through the space between pouches. Stacking pouches flat on top of each other traps moisture and blocks steam.
- Place heavier packs on the bottom rack. CSR-wrapped cassettes go on the bottom; lighter pouches go on top. This prevents condensation from heavier packs dripping onto lighter ones and compromising the sterile barrier.
- Never place pouches inside CSR-wrapped packs. The wrap creates its own barrier that prevents steam from reaching the pouch's internal indicator reliably.
- Run a biological indicator (spore test) at least weekly, or per your provincial regulatory requirements. The RCDSO recommends weekly biological monitoring for all sterilizers used in dental practices. Document every result.
Storage: Maintaining Sterility Until Use
Properly sterilized and packaged instruments maintain their sterility based on event-related conditions, not arbitrary time limits. This means a properly sealed, undamaged pouch stored in a clean, dry environment remains sterile until the packaging integrity is compromised. However, best practice in most Canadian dental offices is to reprocess instruments that have been stored for more than 12 months, or sooner if the packaging shows any sign of damage, moisture, or contamination.
Store sterilized packs in closed cabinets or drawers — not on open shelving exposed to dust and splash. Use a first-in, first-out (FIFO) rotation system to ensure older packs are used before newer ones.
Building Your Sterilization Supply Order
For a general dental practice with 3–5 operatories in Ontario, a typical quarterly sterilization supply order might include:

Frequently Asked Questions
Q: What class of chemical indicator should I use inside sterilization pouches?
The RCDSO recommends using an internal chemical indicator (Class 4 or higher) in every package processed in your sterilizer. Class 5 integrating indicators provide the highest level of chemical assurance and should be included in the most challenging pack of every load. EBIKO Dental carries both Class 4 pouches with built-in indicators and standalone Class 5 indicator strips.
Q: How often should I run biological indicator (spore) tests on my autoclave?
The RCDSO recommends at least weekly biological monitoring for all sterilizers in Ontario dental practices. Some practices run spore tests daily or with every implant/surgical load for added assurance. Document and retain all biological monitoring results as part of your IPAC records.
Q: Can I reuse sterilization pouches?
Sterilization pouches are designed for single use. The paper barrier degrades during the sterilization cycle, and a reused pouch cannot reliably maintain sterility. Additionally, the chemical indicator on the pouch has already reacted and cannot be re-read. The cost of a new pouch is negligible compared to the risk of a sterility failure — always use a fresh pouch for each cycle.
