• Which mouthwash kills the
most oral bacteria?

• I plan to show that people will
choose Listerine as the best
mouthwash.
• What I had to do was to test all four mouthwashes,
Listerine, Scope, Crest and Antiseptic oral rinse on a
student over 12 years old, or an adult. I let the person
rinse their mouth with Antiseptic oral rinse for ten
seconds then they had to spit it out and rinse their mouth
with water, then I would ask the person to rate the
mouthwash from one through five. One being the lowest
and five being the highest. And then I would do the same
process with the others and at the end when their
finished I ask them out of all four mouthwashes which
one would be the best.

The oral bacteria cavity of the newborn baby doesn’t
contain bacteria but rapidly becomes colonized with
bacteria. Dental plaque is the material that adheres to
the teeth and consists of bacterial cells, salivary
polymers and bacterial extra-cellular products. Most of
the bacterial species found in the mouth belong to
microbial communities, called biofilm, a feature of which
is interring bacterial communication. A method of
communication involves cell. Oral bacteria have been
shown to produce small peptides such as competence
stimulating peptides which can help promote single
species bioflim formation.
Cont’d
The mouth harbors a diverse, abundant and complex
microbial community. This highly diverse micro flora
inhabits the various surfaces of the normal mouth.
Bacteria adhesion is particularly important for oral
bacteria. Oral bacteria have evolved mechanisms to
sense their environment and evade or modify the host.
Bacteria occupy the ecological niche provided by both
the tooth surface and gingival epithelium. However a
highly efficient innate host defense system constantly
monitors the bacterial colonization and prevent bacterial
invasion of local tissues.

• I tested twelve people to test my experiment
which was which mouthwash was the best. Most
of the people choose Listerine as the best. From
the twelve people eight of them choose Listerine
as the best. Then after Listerine came scope as
the second best mouthwash. I let the twelve
people test four different type of mouthwash
which was Listerine, scope, Crest, and antiseptic
oral rinse. I made them rate from 1 through 5,
five being the highest and one being the lowest.
I made them rate each and every one of the four
mouthwashes and Listerine came up with the
highest votes.
• Well I proved my hypothesis was
true or correct. Because in my
hypothesis I said that Listerine will
be the best mouthwash in it was
true. According to my data my
prediction was truly correct.
