| description | Introduction: The air–water syringes, ultrasonic scalers, high
speed air turbine handpieces are connected to dental units by a
network of small-bore plastic tubes through which water and air
travel to activate or cool the instruments and it had been shown
that this system is extensively contaminated with microbial
biofilms and pose a potential risk of infection for patients as
well as dental professionals.
Aim: To evaluate and compare the efficacy of various
disinfectants in reducing the microbial colony count in water
derived from Dental Unit Waterlines.
Materials and Methods: Five random dental units were selected
and samples were collected before and after intervention
with 5 disinfectants (0.02% H2
O2
continuously, 0.02% H2
O2
continuously with shock treatment with 0.25% H2
O2
weekly,
0.12% Chlorohexidine and 12% Ethanol overnight, 1:50 Original
Listerine overnight, 2% Sodium Perborate and 2% EDTA 5
minutes in morning) using different disinfection methods for 4
weeks. Samples were cultured on Reasoner’s 2A (R2A) agar for
microbial counting.
Results: Results were recorded as Colony forming units/ml (cfu/
ml) and were evaluated statistically. Results showed that all the
dental unit waterlines were heavily contaminated with microbes
before any intervention. After 1 day of disinfection regime the
counts reduced significantly and showed progressive reduction
in consecutive weeks. Goals set by ADA & CDC were ultimately
achieved at the end of 4 weeks.
Conclusion: All the disinfectants were equally effective in
reducing the microbial colony count of DUWLs, irrespective of
their concentration and method of disinfection. |
