Between the control agar plates and the three disinfection methods used a significantly lower colony count was established for colonies recorded in the surgery assessed as a whole, the X-ray unit, and the ri ght side desk. The disinfection of dental surgery r equires sufficient time as it not only includes the working surfaces but also various inanimate objects. Surface disinfectant spray followed by hydrogen peroxide decontamination has potential for dental surgery, as the colony-forming units have been r educed further compared to spray alone and even just fog alone for all the various areas of the dental surgery that was assessed. The infection control protocols with hydrogen peroxide vapor would ensure the maximum efficacy of the disinfection protocols. The infection control protocols with hydrogen peroxide vapor would ensure the maximum efficacy of the disinfection protocols.It is well known that angiotensin-converting enzyme 2 (ACE2) is an important host factor responsible for the attachment of severe acute respiratory syndrome coronavirus clad 2 (SARS-CoV-2). ACE2 has been predominantly reported to be present in lungs and nasal mucosa, which is the most common site for the initiation of COVID-19.1 Apart from lungs, ACE2 is also expressed in heart, blood vessels, kidneys, brain, intestines, etc.2 Recently various locations of the oral cavity have been found to be associated with differential expression of ACE2 protein, with the tongue being the most common site.3 Moreover, the salivary glands have also been regarded as a potential source of SARS-CoV-2 infection due to the presence of the ACE2 receptor.4 However, till date there is no strong scientific evidence that has proved the existence and interaction of ACE2 protein and spike receptor of SARS-CoV-2 on oral mucosal and salivary gland epithelial cells. Cerebral ischemia-reperfusion injury (CIRI) can cause brain tissue inflammation, neuronal degeneration,
