Sterilization is the backbone of infection prevention and control (IPAC) at every dental practice. Choosing the right sterilization pouches, chemical indicators, biological monitors, and cassettes determines whether your practice meets RCDSO standards — and whether your instruments are genuinely safe for the next patient. This guide covers the complete sterilization workflow with product recommendations from EBIKO Dental.
As of June 2026, the Royal College of Dental Surgeons of Ontario (RCDSO) continues to enforce strict IPAC protocols for all dental practices in the province. Whether you operate a solo practice in North York or a multi-chair clinic in Mississauga, your sterilization workflow must be documented, monitored, and verifiable at every stage. The good news: building a reliable system does not require premium-priced equipment from the large distributors. EBIKO Dental supplies Canadian-made and internationally certified sterilization products that meet every regulatory requirement at a fraction of the cost.
Understanding the Sterilization Workflow: From Chairside to Storage
Before examining individual products, it helps to map the complete instrument reprocessing cycle that the RCDSO and Public Health Ontario (PHO) expect every practice to follow:
- Point-of-use treatment: Instruments are wiped or rinsed immediately after use to prevent bioburden from drying.
- Transport: Contaminated instruments move to the reprocessing area in a covered, puncture-resistant container.
- Cleaning: Manual scrubbing or ultrasonic cleaning removes organic debris. This step is critical — sterilization cannot compensate for inadequate cleaning.
- Inspection and packaging: Clean instruments are inspected, organized into cassettes or pouches, and sealed with appropriate chemical indicators.
- Sterilization: Packaged instruments are processed in an autoclave (steam sterilizer) following the manufacturer's validated cycle parameters.
- Monitoring: Each load is verified using mechanical, chemical, and biological indicators.
- Storage: Sterilized packages are stored in a clean, dry area until use. Event-related shelf life applies — packages remain sterile as long as the packaging integrity is maintained.
Every product discussed below maps to a specific stage in this workflow.
Sterilization Pouches: Your First Line of Packaging
Self-seal sterilization pouches are the workhorse of dental instrument packaging. They provide a barrier against recontamination after autoclaving and include built-in chemical indicators that change colour to confirm exposure to sterilization conditions.
EBIKO Dental's Sterilization Pouches Class 4 are available in six sizes to accommodate everything from single hand instruments to full surgical kits. Class 4 indicators are multi-variable — they respond to time, temperature, and the presence of steam, providing a more reliable confirmation than basic Class 1 indicators that only confirm the package passed through the sterilizer.
When selecting pouch sizes for your practice, consider your most common instrument sets:
- Small pouches (2.25" x 8" or 3.5" x 9"): Ideal for individual hand instruments, scalers, curettes, and endodontic files.
- Medium pouches (5.25" x 10" or 7.5" x 13"): Suitable for composite placement instruments, carvers, and small surgical kits.
- Large pouches (10" x 15" or 12" x 18"): Designed for full extraction forceps, cassettes that do not have their own wrap, and larger surgical instrument sets.
Pro Tip: Order at least two sizes of pouches. Using oversized pouches for small instruments wastes material and creates excess air pockets that can compromise steam penetration. A 200-pack of EBIKO Class 4 pouches keeps your per-unit cost low while maintaining compliance.
Chemical Indicators: Verifying Every Load
The RCDSO requires that every sterilization load includes appropriate chemical indicators. EBIKO Dental carries indicators at multiple classification levels to cover your monitoring needs:
Autoclave Sterilization Tape (Class 1 External Indicator)
EBIKO Autoclave Sterilization Tape is available in three sizes and serves as a Class 1 process indicator. The tape's diagonal stripes change colour after exposure to steam sterilization conditions, providing a quick visual confirmation that a package has been processed. This is your minimum external indicator — it goes on every package, every load.
Chemical Indicator Adhesive Strips (Class 4)
EBIKO Chemical Indicator Adhesive Strips provide Class 4 multi-variable verification. These are placed inside the package (between instruments or on the inner surface of a pouch) to confirm that sterilization conditions reached the instruments themselves — not just the outside of the package.
Class 5 Chemical Integrators
For the highest level of chemical monitoring, EBIKO Dental offers Class 5 Chemical Integrator Indicators in packs of 200. Class 5 integrators are designed to correlate with the performance of biological indicators — they react to all critical sterilization variables (time, temperature, and steam quality) and provide a pass/fail result that closely mirrors what a spore test would show.
The 3M Attest Steam Chemical Integrator 1243A is another option for practices that prefer the 3M brand. Available in a 500-count bag, it provides the same Class 5 integrator performance with the 3M quality assurance backing.
Pro Tip: Use Class 1 indicators on the outside of every package and Class 5 integrators inside at least one package per load. This dual-indicator approach satisfies RCDSO documentation requirements and gives your team confidence that sterilization conditions were achieved throughout the load.
Biological Indicators: The Gold Standard of Sterilization Monitoring
Chemical indicators confirm exposure to sterilization conditions. Biological indicators (BIs) confirm that sterilization actually killed the most resistant organisms. The RCDSO mandates biological monitoring at least weekly for all dental autoclaves, though daily monitoring is considered best practice.
EBIKO Dental carries the Terragene Biological Indicators for Steam Sterilization (BT20) — a 100-count box that provides reliable spore-based verification with a 24-hour incubation period. Each self-contained vial includes Geobacillus stearothermophilus spores, the standard organism used to challenge steam sterilizers.
To incubate your biological indicators, EBIKO also supplies the Terragene Dual Incubator (IC10/20), which accommodates both the 24-hour and rapid-read biological indicator formats. Having a dedicated incubator in your reprocessing area eliminates the need to send spore tests to an external lab, giving you same-day or next-day results.
Sterilization Cassettes: Organizing for Efficiency and Safety
Loose instruments in sterilization pouches work for small practices. But as your instrument volume grows, cassette-based systems become essential for efficiency, instrument protection, and traceability.
EBIKO Dental offers an extensive range of sterilization cassettes in sizes from 3-instrument to 20-instrument configurations:
- 5-Instrument Cassette (Detachable) — perfect for basic exam setups: mirror, explorer, cotton pliers, scaler, and curette.
- 10-Instrument Cassette (Detachable) — suits restorative and composite placement kits.
- 20-Instrument Cassette (Detachable) — designed for surgical extraction setups and complex restorative trays.
For orthodontic practices, the 4-Plier/Cutter + 3-Instrument Cassette and the 7-Plier/Cutter + 3-Instrument Cassette accommodate the unique instrument shapes that standard cassettes cannot.
Specialty accessories like the Hinged Instrument Clips, Needle Cap Holders, and Barcode Clips allow you to customize cassettes for your practice's specific workflow.
Pro Tip: Colour-code your cassettes by procedure type. Use one colour of silicone rail for hygiene setups, another for restorative, and a third for surgical. This visual system reduces setup errors and speeds operatory turnover by 2 to 3 minutes per patient.
CSR Wrap for Larger Instrument Sets
For instrument trays and cassettes that are too large for standard pouches, EBIKO CSR Sterilization Wrap is available in five sizes. CSR (Central Service Room) wrap provides a breathable barrier that allows steam penetration while maintaining sterility after processing. Proper wrapping technique — typically a sequential double-wrap — is essential for maintaining the sterile barrier during storage and transport.
Barrier Products and Surface Protection
Sterilization covers your reusable instruments, but single-use barrier products protect surfaces and equipment that cannot be autoclaved. EBIKO Dental's barrier product lineup includes:
- Barrier Film 4" x 6" (1,200/Roll) — self-adhesive film for light handles, control panels, drawer pulls, and any high-touch surface. Easy-to-peel design speeds operatory turnover between patients.
- Barrier Film Dispenser — wall-mounted for quick, one-handed access during room setup.
- Barrier Envelopes (3 styles, 100/pk) — designed for digital sensor protection during radiographic procedures.
- Headrest Covers (500/pk) — two sizes to fit standard and paediatric headrests.
- Plastic Tray Sleeves 10.5" x 14" (500/pk) — keeps instrument trays protected during transport and setup.
Surface Disinfection: Completing the IPAC Cycle
After removing barrier products between patients, exposed surfaces require disinfection with a Health Canada-approved product. EBIKO Dental carries two of the most widely used disinfectant wipes in Canadian dental practices:
- CaviWipes Surface Disinfectant Wipes (160/canister) — alcohol-based, broad-spectrum disinfection with a 2-minute contact time.
- CaviWipes 2.0 XL (65/canister) — larger 9" x 12" format for countertops and larger surfaces.
- OPTIM 33TB Disinfectant Wipes (160/pack) — hydrogen peroxide-based, unscented, with a 1-minute contact time. Preferred by practices that want to avoid alcohol-based products.
Building Your IPAC Supply Order
For a typical 4-chair dental practice in the GTA processing 20 to 30 patients per day, here is a reasonable monthly supply baseline:
- Sterilization pouches: 2 to 3 boxes across 2 sizes
- Autoclave tape: 1 roll per operatory
- Chemical integrators (Class 5): 1 box of 200 (covers 6+ months at one per load)
- Biological indicators: 1 box of 100 (covers approximately 2 years at weekly testing, or 3+ months at daily testing)
- Barrier film: 2 to 3 rolls
- Disinfectant wipes: 4 to 6 canisters
- Headrest covers and tray sleeves: 1 box each
EBIKO Dental offers free shipping on orders over $99 CAD within the GTA, $199 CAD across Ontario, and $299 CAD for the rest of Canada. A single IPAC supply order typically qualifies for free shipping, keeping your per-unit costs competitive with or below the large national distributors.

Frequently Asked Questions
Q: How often does the RCDSO require biological indicator testing for dental autoclaves?
The RCDSO mandates biological indicator testing at least once per week for every sterilizer used in an Ontario dental practice. However, daily biological monitoring is considered best practice and is recommended by Public Health Ontario's IPAC guidelines. Each test result must be documented and retained as part of your sterilization records.
Q: What is the difference between Class 4 and Class 5 chemical indicators for dental sterilization?
Class 4 indicators are multi-variable and react to two or more sterilization parameters such as time and temperature. Class 5 chemical integrators react to all critical variables — time, temperature, and steam quality — and are designed to correlate with biological indicator performance. Class 5 integrators provide the highest confidence short of a biological spore test and are recommended for use inside at least one package per sterilization load.
Q: Can sterilization pouches be reused after autoclaving?
No. Self-seal sterilization pouches are single-use products. The adhesive seal and chemical indicator are designed for one sterilization cycle only. Reusing pouches compromises the sterile barrier and violates RCDSO infection prevention and control standards. Always use a fresh pouch for each sterilization cycle.
