[COVID-19] Reduction of Sars-CoV-2 Oral Viral Load With Prophylactic Mouth Rinse

January 31, 2022 updated by: Ryan F. Bloomquist, Augusta University

Reduction of Sars-CoV-2 Oral Viral Load With Prophylactic Mouth Rinse

The purpose of this study is to test the effectiveness of prophylactic mouth rinses in reducing the amount of viruses, specifically SARS-CoV-2 in the oral cavity. This research will guide dental and medical providers on best practices to be performed prior to dental and medical procedures involving the oral cavity.

Study Overview

Detailed Description

In response to SARS-CoV-2 the dental and greater healthcare communities have devised ways to combat the spread of the virus. Many dentists and physicians have advocated the use of prophylactic oral rinses for reduction of COVID-19 viral load in all patients prior to treatment in the oral pharyngeal cavity, but the effectiveness of these measures has not been validated with empirical evidence. The investigators will test COVID-19 positive hospital inpatients before and after the use of different combinations of oral rinses to provide guidance on best measures for dental or medical treatment. This research is imperative and essential as prophylactic rinses are already being used at AU and globally, without data to support their effectiveness specifically in COVID-19 positive patients.

Oral rinses have been used as an industry standard in dentistry for decades to reduce oral levels of pathogens including bacteria and viruses. According to the American Academy of Dentistry mouth rinses can be broken down into two categories, cosmetic and therapeutic. Those categorized as therapeutic include chlorhexidine, essential oils, fluoride, and hydrogen peroxide. These rinses are routinely used in both dental practices as well as in the OR setting prior to any invasive procedure involving treatment of the oral cavity. However, these mouth rinses, are typically utilized to reduce risk of infection to the patient. By disinfecting the oral cavity through bacteriostatic, bactericidal, and virucidal rinses practitioners can mitigate the risk of spreading an infection from a patient's mouth or the outside environment to other parts of their body. Prophylactic rinses are often used prior to routine dental procedures like fillings and cleaning to more invasive interventions like jaw reconstruction and tumor resection. This simple, cheap and innocuous procedure is now being used for a different purpose. In light of the COVID-19 pandemic, reduction in the spread of oral and respiratory borne viruses has become paramount in the global battle against coronavirus. Both dentists and medical providers, including ear nose throat specialists and anesthesiologists who routinely intubate patients, have implemented the use of these virucidal mouth rinses to reduce viral loads of both COVID-19 positive and non-infected patients. Dentists are particularly at risk for transmission of COVID-19 because they work directly in the oral cavity where the virus resides and the work they do creates an enormous amount of aerosols. In addition to a multitude of barrier and personal protective equipment (PPE) techniques being implemented, prior to procedures in the oral cavity patients are asked to rinse and spit different regimens of mouth rinses to reduce the chance of spreading SARS-CoV-2 to healthcare staff.

While healthcare workers have had to act quickly to respond to the pandemic and reduce the risk of spreading coronavirus, there is a lack of empirical evidence to support current practices. Here the investigators aim to address three questions; 1: Does oral prophylaxis effectively reduce oral viral load specifically of SARS-CoV-2; 2: If so for what duration is oral prophylaxis effective before viral load recovers in the oral cavity; 3: Which combination of virucidal prophylaxis if any is most effective.
