Temples Contamination In Spectacle Worn By Dentist In Dental Clinics

Abstract

Introduction
Dental practice has a risk of its own. Aerosol, splatters, fumes and irritating chemical vapours are the day to day events. During long
hours of clinical work, auto innoculations are also possible. Then the next comes the fomite contamination which is carried out of
the clinic area. Contamination on cell phones, ipads, watches and spectacles are always a risk factor. This study is done to screen the
spectacles for the contamination occurring during the clinic hours.
Material and Methods
Study done in dental clinics in dentists wearing spectacles .Samples were collected from the spectacles frame at temples using
moistened swab swabs samples were collected and transported to the microbiology laboratory. They are inoculated onto Blood agar
and Brain heart infusion agar. The plates were incubated at 37 degree C for 24 hrs aerobically. After incubation the plates were
checked for the total colony forming units and for the presence of bacteria of oral origin.
Result
The screening of spectacles for the microbial load show a heavy increase of bacterial count in the spectacles, which includes salivary
streptococci and CoNS
Conclusion
The spectacle frame is frequently touched by the dentist during the treatment. The area touched is close to the eye lens and eye
itself. So this practice carries a definite risk for the dentist
