Infection control in dental surgical suites

Infection Control in Dental Minor Surgery Rooms in Compliance with Ministry of Health Standards

Infection control is a mandatory requirement during the licensing appraisal of dental minor surgery rooms. If standards are not met, the clinic is not permitted to perform minor surgical procedures – including Implant surgery – and may even face suspension of operations.

The article below presents the legal basis, design standards, sterilization procedures, and common mistakes from the perspective of experts in design, regulatory compliance, and infection control.

1. Legal Basis for Infection Control in Minor Surgery Rooms

1.1 Mandatory Legal Documents

  • Law on Medical Examination and Treatment 2023 – Infection control requirements for healthcare facilities

  • Decree 96/2023/ND-CP – Conditions for operating license issuance

  • Circular 20/2021/TT-BYT – Waste management & infection control

  • Decision 3916/QD-BYT – Guidelines on infection control in healthcare facilities

According to regulations:

Facilities performing minor surgery must ensure a high level of sterility, compliant surgical room standards, and a complete infection control process. Failure to comply → Not permitted to perform minor surgical procedures.

2. Objectives of Infection Control in Minor Surgery Rooms

  • Prevent post-operative infections

  • Avoid cross-contamination

  • Protect patients and healthcare staff

  • Ensure surgical-level sterility

  • Meet Ministry of Health licensing standards

3. Design Standards for a Sterile-Compliant Minor Surgery Room

3.1 Space Requirements

  • Separate, enclosed room

  • Minimum area: 12–15 m²

  • Antibacterial, easy-to-clean surfaces

  • Not located near toilets or waste areas

3.2 Air Control

  • Positive air pressure

  • Clean, low-dust air

  • Air filtration system (HEPA recommended)

  • Limited door opening during procedures

3.3 Antibacterial Materials

  • Medical-grade antibacterial paint

  • Smooth walls and ceilings without gaps

  • Waterproof, antibacterial flooring

  • Do not use standard MDF wood materials

4. Sterilization Procedures in Dental Minor Surgery Rooms

4.1 Before Surgery

  • Room disinfection

  • Preparation of sterile instruments

  • Surgical handwashing

  • Wearing sterile surgical attire

  • Placement of sterile drapes

4.2 During Surgery

  • Do not touch non-sterile areas

  • Minimize entry and exit

  • No unnecessary talking – limit droplet spread

  • Strict sterile instrument control

4.3 After Surgery

  • Proper collection of medical waste

  • Surface disinfection

  • Instrument processing: washing – sterilizing – drying

  • Room ventilation

5. Sterility Control of Minor Surgical Instruments

Mandatory equipment:

  • Class B autoclave sterilizer

  • Ultrasonic cleaner

  • Instrument drying cabinet

  • Sterile pouch sealing machine

  • Biological & chemical tests for autoclave monitoring

Process:

Wash → Dry → Package → Sterilize → Store in sterile condition

6. Surface & Equipment Infection Control

Must be disinfected:

  • Surgical chair

  • Handpieces and handles

  • Surgical lights

  • Instrument trays

  • Work tables

  • Door handles

Disinfectants:

Chlorhexidine / Medical alcohol / Ministry of Health–approved disinfectant solutions

7. Water – Air – Suction Source Control

A compliant minor surgery room must ensure:

  • Clean dental unit water – bacteria-free

  • Clean compressed air – oil-free – moisture-free

  • Properly functioning central suction system

  • No backflow contamination

8. Mandatory Infection Control Documentation for Appraisal

The Department of Health will inspect:

  • Minor surgery sterilization procedures

  • Autoclave sterilization logbooks

  • Autoclave biological test records

  • Surface disinfection procedures

  • Staff sterilization training records

Missing documentation → Failure of appraisal.

9. Common Mistakes Causing Minor Surgery Rooms to Fail Compliance

  • No positive pressure system

  • No separation of sterile zones

  • Not using a Class B autoclave

  • No biological testing of autoclave

  • Incorrect sterile workflow

  • No surface disinfection

  • No air and water control

  • No sterilization documentation

10. Consequences of Non-Compliant Minor Surgery Rooms

  • Not permitted to perform minor surgery – Implant procedures

  • Licensing application rejected

  • Suspension of operations

  • Risk of post-operative infection

  • Loss of clinic reputation

11. Infection Control Compliance Checklist for Minor Surgery Rooms

A room is compliant when it has:

  • Enclosed, clean surgical room design

  • Positive pressure – clean air

  • Class B autoclave + biological testing

  • Complete sterilization procedures

  • Antibacterial materials

  • Controlled water – air – suction systems

  • Infection control documentation

12. Frequently Asked Questions (FAQ)

12.1 Is positive pressure mandatory in a minor surgery room?

It is strongly recommended if aiming to achieve a high sterility standard.

12.2 Can minor surgery be performed without a separate room?

No. It does not meet licensing standards.

12.3 How often should biological testing of the autoclave be conducted?

At least once per week.

12.4 Why are many Implant rooms rejected during licensing?

Due to incorrect sterile design and incomplete infection control documentation.
