Evaluation of SARS-COV-2 Viral Load of Covid-19 Patients After Rinsing With Oral Antimicrobial Mouthwashes
2022年2月24日 更新者：Hospital Israelita Albert Einstein
Evaluation of Viral Load of SARS-COV-2 Virus in the Oral Cavity After Rinsing With Oral Antimicrobial Mouthwashes in Patients Covid-19.
The aim of this study is to analyze the efficacy of oral disinfection with 0.075% Cetylpyridinium Chloride alone and 0.075% Cetylpyridinium Chloride associated with 0.28% zinc lactate in reduction of the viral load of SARS-CoV-2 in the oral cavity.
Patients of both sexes, in the age-range between 18 and 90 years, diagnosed positive for SARS-CoV-2 by the RT-PCR method, and who demand oral hygiene care and other preventive and therapeutic dental procedures, will be included in this randomized clinical study.The study will comprise patients hospitalized in common beds, without mechanical ventilation - who will be divided into three groups.
Some of these protocols with the use of antimicrobial solutions are hoped to be efficient in reducing the viral load in the oral cavity.
This is a factor that could contribute to reducing contamination of the environment caused by aerosols resulting from dental procedures, in addition to helping with the improvement in biosafety protocols against SARS-CoV-2.
研究概览
详细说明
Each group of patients will receive specific interventions, as follows: 0.075% Cetylpyridinium Chloride mouthwash (Group 1); 0.075% Cetylpyridinium Chloride associated with 0.28% zinc lactate mouthwash (Group 2), negative control, distilled water (Group 3).
To monitor the viral load, the following procedures will be performed: saliva collection, in time intervals before mouth rinsing with the solutions at baseline (T0), immediately after (T1), 30 min (T2), and 1 hour after mouth rinses (T3).
SARS-CoV-2 will be quantified by Real Time quantitative reverse transcription polymerase chain reaction (RT-qPCR) assays.
