Cross-infection control in dental laboratories

Area of Science:

• Dental Public Health
• Infection Control
• Laboratory Safety

Background:

• Cross-infection control is critical in dental laboratories to prevent disease transmission.
• Adherence to safety protocols is essential for both laboratory staff and patients receiving dental prostheses.

Purpose of the Study:

• To survey the attitudes and practices of dental laboratories regarding cross-infection control.
• To identify gaps in current cross-infection control policies and procedures within dental laboratories.

Main Methods:

• A survey was distributed to 800 dental laboratories registered with the Dental Laboratories Association.
• A response rate of 22% (175 laboratories) was achieved, with results considered a guide only due to the low response rate.

Main Results:

• 49% of respondents had a cross-infection policy; 64% of those without planned to implement one.
• 30% of laboratories received known undisinfected work; impressions (77%) and dentures (51%) were most frequently disinfected.
• Glove use was reported by 44% when handling received work, and 74% wore eye protection during prosthesis work. Disinfection of pumice (61%) and polishing instruments (93%) was notably low. 46% had Hepatitis B immunization policies.

Conclusions:

• Significant variation exists in cross-infection control practices among dental laboratories.
• There is a need for improved adherence to disinfection protocols, particularly for incoming work and equipment, and for comprehensive staff immunization policies.
