Regulations on Sterile Rooms and Minor Oral Surgery Rooms in Dental Clinics Under MOH Standards

The sterile room and minor oral surgery room are mandatory functional areas in dental clinics performing Implant placement, oral surgery, surgical tooth extraction, bone grafting, sinus lift procedures, and periodontal surgery. If these rooms are not designed in compliance with regulatory standards, the clinic may be denied an operating license or be subject to suspension.

This article provides a comprehensive overview of legal regulations, technical standards, and practical experience from dental clinic design specialists.

1. Definition of Sterile Room and Minor Oral Surgery Room

1.1 What Is a Dental Sterile Room?

A sterile room is a highly controlled infection-control environment used for invasive procedures such as:

  • Dental Implant placement

  • Bone grafting and sinus lift

  • Periodontal surgery

  • Surgical extraction of impacted wisdom teeth

  • Oral surgery procedures

Primary objective: Prevent microbial contamination, maintain a clean surgical environment, and reduce postoperative infection risks.

1.2 What Is a Minor Oral Surgery Room?

A minor oral surgery room is used for low- to medium-level invasive procedures requiring sterile conditions but not at the level of a hospital operating theater.

Examples include:

  • Wisdom tooth extraction

  • Gingival surgery

  • Gingivectomy

  • Periodontal curettage

  • Suturing oral wounds

2. Legal Basis Governing Sterile and Minor Surgery Rooms

Key regulations issued by the Ministry of Health (MOH) of Vietnam include:

Law on Medical Examination and Treatment 2023
Healthcare facilities must ensure adequate infrastructure, equipment, and infection control conditions in accordance with MOH regulations.

Decree No. 96/2023/ND-CP
Facilities performing invasive procedures must arrange separate sterile or procedure rooms and ensure proper infection control.

Circular 41/2011/TT-BYT on Infection Control
Procedure rooms must ensure aseptic processes, separated clean–contaminated workflows, and easily disinfected surfaces.

Healthcare Facility Design Standards – MOH

  • Separate minor surgery room required for invasive procedures

  • Dedicated instrument sterilization area

  • Documented infection control procedures

3. Area Standards for Sterile and Minor Surgery Rooms

3.1 Minimum Area for Licensing Approval

  • Minor oral surgery room: ≥ 10–12 m²

  • Sterile Implant surgery room: ≥ 12–15 m²

  • Minimum room width: ≥ 3 m

  • Minimum ceiling height: ≥ 2.7 m

⚠️ Rooms smaller than these dimensions are typically rejected during appraisal.

3.2 Space Layout Requirements

Must include:

  • Surgical dental chair

  • Monitor placement area (for Implant procedures)

  • Sterile instrument table

  • Surgical handwashing sink

  • Minimum 80 cm clearance around the chair for operator movement

4. Material Standards for Sterile Rooms

4.1 Walls – Ceiling – Flooring

Mandatory characteristics:

  • Smooth, dust-resistant surfaces

  • Water-resistant

  • Easy to disinfect

Suitable materials:

  • Walls: Medical-grade Compact panels, Laminate panels, or epoxy coating

  • Ceiling: Antibacterial sealed ceiling systems

  • Floor: Medical vinyl, epoxy flooring, or anti-static materials

4.2 Materials Not Permitted

  • Conventional paint prone to peeling

  • Ceramic tiles with exposed grout lines

  • Standard gypsum ceilings

  • Moisture-absorbing materials susceptible to mold

5. Mandatory Sterilization and Infection Control Systems

5.1 Clean–Contaminated Workflow Separation

Must separate:

  • Doctor circulation path

  • Clean instrument flow

  • Medical waste flow

No cross-traffic allowed.

5.2 Instrument Sterilization System

Required:

  • Autoclave sterilizer

  • Sterile packaging machine

  • Instrument washing sink

  • Three-step disinfection protocol

5.3 Air Quality Control

Strongly recommended for Implant surgery:

  • Positive air pressure

  • HEPA filtration system

  • Independent air-conditioning system

  • Dust control measures

6. Required Equipment in Minor Surgery and Implant Rooms

Mandatory equipment includes:

  • Surgical dental chair

  • Surgical light

  • Surgical suction unit

  • Sterile minor surgery instrument set

  • Vital signs monitor (for Implant procedures)

  • Emergency oxygen cylinder

  • Anti-shock kit

  • Medical suction pump

  • Segregated medical waste containers

7. Common Errors Leading to Licensing Rejection

  • No separate surgery room

  • Insufficient room area

  • No sterilization area

  • Non-medical-grade materials used

  • Absence of infection control procedures

  • No surgical handwashing sink

  • No separation of clean and contaminated flows

  • Missing emergency equipment

  • Incorrect design from the beginning

These are common reasons for dossier rejection.

8. Design Process for a Compliant Sterile Room

Step 1 – Legal Assessment

Determine:

  • Whether Implant procedures are performed

  • Whether minor surgery procedures are registered

  • Required sterility level

Step 2 – MOH-Compliant Design

Include:

  • Standardized area dimensions

  • Medical-grade materials

  • Clean–contaminated workflow design

  • Sterilization system planning

  • Required equipment layout

Step 3 – Construction According to Appraisal Standards

Ensure:

  • Correct materials used

  • Accurate room dimensions

  • Proper layout execution

Step 4 – Licensing Documentation Preparation

Include:

  • Floor plan drawings

  • Equipment list

  • Sterilization protocols

  • Legal documentation

9. Role of the Sterile Room in Licensing

If Implant or invasive procedures are performed:

  • No sterile room → license will not be granted

  • Incorrect design → mandatory correction required

  • Inadequate sterility → risk of operational suspension

10. Frequently Asked Questions (FAQ)

Is a minor surgery room mandatory?
Yes, if the clinic performs invasive procedures.

Is a separate sterile room required for Implant procedures?
Yes, it is mandatory.

Minimum area for an Implant surgery room?
Typically 12–15 m² for licensing approval.

Is an air filtration system required?
Not strictly mandatory, but strongly recommended for Implant surgery.

Can a standard treatment room be used for minor surgery?
No. A separate room is required.

11. Practical Insights from Design Experts

Most license rejections occur because:

  • Incorrect design from the outset

  • Misunderstanding MOH standards

  • Lack of a properly defined sterile room

  • Use of non-compliant materials

  • Improper clean–contaminated workflow

Proper design from the beginning ensures:

  • Faster licensing approval

  • No costly renovation

  • Stable long-term operation

  • Enhanced professional credibility
