The oral flora is one of the most diverse bacterial floras worldwide. Oral bacteria are equally distributed worldwide; most of the same types of bacteria are present throughout the world. More specifically, they are independent of local differences. This happens because the teeth and the mouth cavity can easily support the formation of the biofilm due to their optimum conditions and their non-shedding effects. Furthermore, they have the ability to be transferred among the hosts by a direct contact of the mouth cavities and the exchange of saliva.

1.2. Bacteria and Biofilm formation

According to the medical dictionary, a biofilm is a “thin layer of microorganisms adhering to the surface of a structure, which may be organic or inorganic,

How much?”,[5] oral bacteria species present in a single oral cavity may reach the impressive number of 650. If we consider that usually oral bacteria double their quantity every 20 minutes, approximately in a 24-hour period, the number of oral bacteria present in the oral cavity may even reach hundreds of billions. Under ideal conditions such as pH and temperature and having the appropriate nutrient supplies oral bacteria can develop and multiply very rapidly as seen in the graph on the right.
1.4. Types of oral bacteria

In general bacterial species are so abundant because they have the ability to be adaptative and resistant to any environmental conditions. This happens because their rate of reproduction is rapid and the genetic mutations of their RNA occur very often.
One of the most abundant and adaptative species of bacteria is streptococci. It is present at almost every part of the human body (e.g. epidermis) and of course in the oral cavity. More specifically, Streptococcus mutans is a bacterium responsible for the formation of the dental plaque.[7]The image on the left displays this bacterial species after Gram

Different formulae are used by mouthwash brands to formulate their products. These may include products such as; alcohol, Sodium Lauryl Sulfate, Essential oils, Fluoride etc. Usually the ingredients are categorized in inactive and active. Active are those that eliminate the bacteria in the oral cavity and inactive ingredients are usually used as carrier agents for the function of the inactive ingredients, e.g. in a mouthwash, alcohol is used as a carrier agent to facilitate the antiseptic function of essential
