Web3 hours ago · However, the pH of the oral cavity does not dip below 6.3 during rest and it is kept near neutral (6.7–7.3) by saliva [ 27 ]. Since smokers have a higher oral pH than non-smokers, there is more room for this pH to remove calcium and deposit it on teeth, perhaps resulting in high amounts of salivary calcium [ 28 ]. WebThe letters pH stand for "power of hydrogen" and the numerical value is defined as the negative base 10 logarithm of the molar concentration of hydrogen ions. pH = -log 10 [H + ] The measurement of the pH of a sample can be done by measuring the cell potential of that sample in reference to a standard hydrogen electrode, as in the accepted ...
