The effect of storage in liquid nitrogen on the recovery of human dental plaque bacteria.

abstract：:One of the most popular drinks worldwide, tea is rich in polyphenols and is beneficial to our health because it contributes to the prevention of many diseases. In the human oral cavity, there are more than 750 different species of bacteria living together within dental plaque. Some of the bacteria are pathogens that c...
