Culturing bacteria from the oral cavity in a dish in the laboratory is an example of what type of study?
a. in vivo
b. in vitro
ð¡. in situ
d. none of the above

The best answer to the question: Culturing bacteria from the oral cavity in a dish in the laboratory is an example of what type of study? Would be, B: In vitro.

Explanation:

When talking about culturing of either bacteria or another type of microorganisms, it is important to know what is the purpose of this culturing, in order to select the best study methods. In the case of oral cavity bacteria, the best way to stdy them is through something called a closed system, or, the use of a petri dish and agar as a medium, with nutrients to make the bacteria present in the dental biofilm, to grow in a controlled manner. In this system, all variables are controlled and the purposes are very clear, which makes the use of this closed system much more efficient than more open ones, such as in vivo studies. This closed system of research for mouth bacteria is an example of in vitro studies, where inside a petri dish, with nutritious agar, and controlled variables, or a test tube, these bacteria are encouraged to grow, but it makes it easy for the scientist to predict exactly what will happen and what the outcome might be.
