University Study
Abstract
Aim: The aim of the present study was to evaluate and compare the efficacy and cytotoxicity of four different mouthwashes containing 1.5% hydrogen peroxide, 0.2% povidone, 0.12% chlorhexidine and 100 ppm molecular iodine for their ability to inactivate severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
Materials and Methods: The SARS-CoV-2 virus stocks were grown in minimum essential medium (MEM) test media, supplemented with 2.0% fetal bovine serum (FBS) and 50 μg/mL gentamicin. Test solutions and virus were incubated at room temperature for three contact times of 15, 30, and 60 seconds. The solutions were then neutralized by a 1/10 dilution in test media containing 10% FBS. Neutralized samples were then incubated for 5 days at 37 ± 2°C at 5% CO2. The test plates were then scored for their cytopathic effect and the log-reduction value (LRV) of the test solution was compared to the negative control (water).
Results: The results showed that the LRV for a 100 ppm molecular iodine oral rinse was significantly greater, at each exposure time, compared with the other three oral rinses in the study with no associated cytotoxicity. The 100 ppm molecular iodine rinse exhibited an LRV of 2.6 at 15 seconds and complete inactivation of SARS-CoV-2 at both 30 seconds and also at 60 seconds with LRV greater than 3.6 for each of those contact times.
Conclusion: The spread of infection through aerosol and splatter has long been considered one of the main concerns in the dental community. A preprocedural rinse with 100 ppm molecular iodine will play a vital role in combating the COVID-19 pandemic by preventing the spread of infection.
In our office for all restorative and hygiene procedures, we offer this preprocedural rinse with 100 ppm molecular iodine to all of our patients to prevent and combat the spread of the COVID-19 pandemic.
