Contamination of Dentist's Hands with and without Finger Rings

Area of Science:

• Microbiology
• Infectious Disease Transmission
• Healthcare Hygiene

Background:

• Healthcare worker hands are a primary vector for infectious disease transmission.
• Microbial growth is enhanced in the moist environment under gloves, especially with prolonged use.
• Pathogenic bacteria and fungi can colonize healthcare workers' hands before glove application.

Purpose of the Study:

• To investigate the impact of finger rings worn by dentists on the prevalence of potentially pathogenic microorganisms on hands.
• To compare microbial contamination levels between dentists wearing rings and those not wearing rings under gloves.

Main Methods:

• Collected skin samples from dentists' hands after professional cleaning and glove disposal.
• Analyzed samples for the presence of potentially pathogenic bacteria and fungi using biochemical and cultural laboratory tests.
• Compared microbial findings between a group of 20 dentists with rings and 20 dentists without rings.

Main Results:

• Significantly higher prevalence of bacteria and fungi on the hands of dentists wearing rings (63%) compared to those without rings (37%).
• Commonly isolated pathogens included Staphylococcus aureus, Escherichia coli, and Candida albicans.
• Ring-wearing correlated with increased microbial load on dentists' hands.

Conclusions:

• Potentially pathogenic microorganisms were found more frequently on the hands of dentists who wore finger rings under gloves.
• The study suggests that finger rings can contribute to increased microbial contamination, posing a potential risk in clinical settings.
• Recommendations for enhanced hand hygiene practices for dentists wearing rings are implied.
