Using Cidex Safely and Effectively
- High-Level Disinfection vs Sterilisation — Immersion in Cidex for 20-45 minutes achieves high-level disinfection; 10-hour immersion achieves cold sterilisation. Use 20-45 minutes for handpieces and flexible instruments between patients; reserve 10 hours for items requiring sterility.
- Instrument Compatibility — Cidex is safe for stainless steel, aluminium, rubber, and most plastics used in dental equipment. Avoid prolonged immersion of chrome-plated or brass fittings -- glutaraldehyde can cause surface corrosion over repeated exposures.
- Solution Activation and Life — Cidex requires activation by mixing the two components before first use; activated solution lasts 14-28 days. Test activated solution with Cidex test strips before each use to confirm effective glutaraldehyde concentration (at least 1.5%).
- Rinsing After Immersion — Thoroughly rinse instruments with sterile or distilled water after Cidex immersion before patient use. Residual glutaraldehyde on instruments can cause tissue irritation -- rinse for at least 30 seconds per instrument.
- Ventilation Requirements — Glutaraldehyde vapour is an irritant -- use Cidex only in well-ventilated areas or under extraction ventilation. Recommended exposure limit is 0.05 ppm ceiling. A covered soaking tray significantly reduces vapour release in clinic environments.
- Disposal Protocol — Spent Cidex solution must be neutralised and disposed of according to local Egyptian environmental regulations. Do not pour undiluted glutaraldehyde down drains -- neutralise with sodium bicarbonate solution before disposal.
Dental High-Level Disinfectants at a Glance

|---|---|---|---|
| Cidex 2% | Glutaraldehyde | 20-45 min | Most dental instruments |
| Hydrogen Peroxide 7.5% | H2O2 | 30 min | Stainless steel, most metals |
| OPA 0.55% | Ortho-phthalaldehyde | 12 min | Flexible endoscopes, plastics |
| Chlorine Dioxide | ClO2 | 3-15 min | Surfaces and instruments |
| Quaternary Ammonium | QUAT | Surface use only | Surfaces only -- not HLD |
How to Use Cidex for Instrument Disinfection
- Activate the Cidex solution by combining the solution and activator components per label instructions.
- Pre-clean instruments thoroughly -- remove all blood, debris and biofilm before immersion.
- Immerse instruments fully for 20-45 minutes for high-level disinfection (or 10 hours for sterilisation).
- Test solution concentration with Cidex test strips before each use cycle.
- Remove instruments, rinse thoroughly with sterile water, and dry before patient use or storage.
