ABSTRACT
COVID-19 is a life-threatening viral infection that considers airborne viruses and it's very hard to control the separation of such a pathogen and early diagnosis and treatment can play important role in directly affects patients prognosis, so the period of infection and diagnosis of COVID-19 with good treatment according to patient vital singe is very important. The current diagnosis of COVID-19 has yet to be further improved. To investigate the effect of normalMouthwashand Teeth Whiting Mouthwash onSARS COV-2 patient Viral load in the oral cavity(Lu et al, 2019). Mouth wash has been done on SARS COV-2 patients for 1 min by normal mouth wash (ganger) group 1 and then mouth swap for RT-PCR of SARS-Cov-2 before and after 30 min of mouth washing and other mouth wash has been done on SARS COV-2 patients for 1 min by whiting mouth wash (Oxiactive) group 2 and then mouth swap for RT-PCR of SARS-Cov-2 to know the variation in CT PCR level pre and post mouth wash and to compare the effectiveness between them. The effectiveness of normal mouth wash of COVID-19 patients reducing the viral load, which is considered as an impotent way to protect from the separation of viral shedding (the 14 patients were COVID -19 PCR positive and then after washing became PCR negative). The effectiveness of whitening mouth wash of COVID-19 patients strong reducing the viral load and most cases are becoming negative PCR, which is considered as an important way to protect from the separation of viral shedding and maximum lowering 14 CT or (16000 folds). Mouth wash according to the result could be the best way to decrease the contamination and infection between dentist and patient. Reducing the nosocomial infection by applying mouth wash for several minutes. The PCR false-negative result could be caused by mouth wash the effect the truth of laboratory tests.
