Cross-infection control in dental laboratories: an overview

Nela Kalpakchieva, Klara Dokova


In the field of dentistry, cross-infection control is an integral aspect of professional dental healthcare practice. Increasing number researchers are focusing their interest on the knowledge, attitudes and practices of dental technicians related to cross-infection control in dental laboratories, as defining good dental practice and patient and professional safety.

The aim of this study is to review the publications on knowledge, attitudes and practices related to cross-infections control in dental laboratories, to establish their geographical and time range, preferred design and the instruments used.

Material and methods: A search for scientific research has been conducted in the electronic databases PubMed, Research gate, Google scholar in May 2023. Keywords used included: dental laboratory, cross-infection control, dental technicians, knowledge, attitudes, practices. A search period has been set as January 2000 to May 2023.

Results: As a result of the pre-established criteria, the literature overview includes 28 publications presenting cross-sectional studies from 19 countries from Europe, Asia, Africa, North and South America. Information on the knowledge, attitudes and practices related to infection control in dental laboratories was gathered through questionnaires. The size of the investigated samples varies: at the individual level - from 11 to 200 working dental technicians, from 48 to 193 dental doctors, from 15 to 400 owners / directors of dental laboratories, and at the group level - from 20 to 96 dental laboratories.

Conclusion: The quality of studies of the knowledge, attitudes and practices of dental technicians related to cross-infection control in dental laboratories can be improved by covering larger samples and using standardized tools.
