Efficacy of Two Mouth Rinses in Reducing Aerosol Bacterial Load during Ultrasonic Scaling

Abstract

Aims:The aim of this study was to compare the efficacy of two mouth washes namely Chlorhexidine 0.2% and 5% green tea mouth rinse when used as pre-procedural rinses in reducing the number of CFU in aerosol generated during ultrasonic scaling. Methodology: 70 subjects were recruited in this study (43 males, 27 females: age range 18-65 years with presence of minimum 20 permanent functional teeth, less than 5 mm mean probing depth and plaque and gingival score between 1-3. Subjects were randomly divided into two groups, group 1 and group 2. Each group comprised of 35 patients. A split mouth design technique was used for collecting the aerosol samples on blood agar Anjum et al.; JAMMR, 31 (7): 1-9, 2019; Article no.JAMMR.53094 2 plates. For every patient, there was a control side and test side of mouth. Ultrasonic scaling was done on control side without pre procedural rinsing and vice versa. Group 1 used 0.2% Chlorhexidine while group 2 rinsed with 5% green tea mouthwash. The blood agar plates were then transported to Microbiology lab and incubated for counting the colony forming units (CFU). Results: Significant reduction of CFU occurred with pre procedural rinsing with both mouthwashes as compared to non-rinsing before ultrasonic scaling and 0.2% Chlorhexidine found to be superior to 5% green tea in reducing bacterial load in aerosol samples Conclusion: Pre procedural mouth rinsing with effective mouthwashes significantly reduces aerosol contamination and should be used before all dental procedures that results in formation of aerosols and splatters along with some other infection control protocol to minimize the risks of cross infection in clinical settings.

Comparison of antimicrobial efficacy of chemical mouthwash and herbal mouthwash

“…The descriptive statistics show that the chlorhexidine group has the maximum reduction in the colony forming units per millilitre, when compared to the Befresh and control group. This is in accordance with the findings of other studies comparing chlorhexidine with cinnamon based as well as other herbal mouth rinse concoctions [18][19][20]. Bonferroni and Post hoc tests done to compare the three groups between each other and evaluate the reduction in bacterial colony forming unit, showed a statistically non-significant result between the Chlorhexidine and Befresh Herbal mouth rinse group as well as the herbal mouth rinse and control group.…”

Plant Cell-Engineered Gold Nanoparticles Conjugated to Quercetin Inhibit SARS-CoV-2 and HSV-1 Entry

“…In addition, many devices used in dental practices, such as ultrasonic scalers, air-water syringes, and dental handpieces, are known to generate water aerosols. Therefore, the above practices increase the risk of exposure to infectious respiratory pathogens, including SARS-CoV-2, to patients and healthcare workers [25,26]. Hence, the strategies directed to minimize the risk of SARS-CoV-2 transmission by targeting the ability of viral particles to fuse with the host cells or by reducing the titers of SARS-CoV-2 in the saliva of infected patients seems to be a promising approach.…”

Significance of chlorine‐dioxide‐based oral rinses in preventing SARS‐CoV‐2 cell entry

“…In addition, many devices used in the dental practice such as ultrasonic scalers, air‐water syringes, and dental handpieces are known to generate water aerosols. Therefore, the above tools increase the risk of exposure with the infectious respiratory pathogens including SARS‐CoV‐2 to the patients and the healthcare workers (Anjum et al, 2019 ; Bidra et al, 2020 ). Hence, the strategies directed to minimize the risk of SARS‐CoV‐2 transmission by targeting the ability of viral particles to fuse with the host cells and/or by reducing the titers of SARS‐CoV‐2 in the saliva of infected patients seems a promising approach.…”
