| Summary: | Introduction: Ultrasonic scaling involves the production of a
high amount of aerosols, which combine with oral microbes
and become a potential source of airborne contaminants.
Chemical antimicrobial agents like Chlorhexidine (CHX) (the
gold standard) are known to reduce microbial contamination
in dental waterlines. However, natural extracts are gaining
popularity as an economical yet effective means of reducing
bacterial load.
Aim: To compare the efficacy of neem and cinnamon extracts in
reducing bacterial contamination during scaling.
Materials and Methods: A single-centered, parallel multiplearm, randomised clinical study was conducted at the Department
of Periodontics and Oral Implantology, SRM Dental College,
Ramapuram, Chennai, Tamil Nadu, India from September 2019
to March 2020. Scaling was performed for patients in all four
groups (n=128, 32 each group) - Water, 0.2% Chlorhexidine,
Neem, and Cinnamon Extract. Two blood agar petri dishes were
placed on either side of the patient at a distance of 40 cm from
the patient’s head, and one blood agar petri dish was placed
on the operator’s chest. The agar plates were then incubated
aerobically for 48 hours for Colony Forming Units (CFU) count.
Statistical analysis was performed using one-way Analysis of
Variance (ANOVA) and Tukey’s posthoc test.
Results: Cinnamon showed a 25.2% reduction in CFUs,
whereas neem showed an 11.7% reduction compared to
distilled water. However, chlorhexidine had the maximum
bacterial reduction. The agar plates at the chest position
had the highest bacterial growth, while the left position had
comparatively fewer microbial colonies.
Conclusion: Chlorhexidine exhibited the highest percentage
of CFU reduction. However, when used as a Dental Unit Water
Line (DUWL) coolant, herbal extracts such as cinnamon and
neem caused a significant reduction in CFUs compared to
distilled water, with cinnamon performing better than neem.
Therefore, herbal extracts like neem and cinnamon can be
considered cost-effective alternatives for minimising aerosol
contamination in DUWL. |
