Testing the Effectiveness
of Toothpaste in Killing
Oral Bacteria

Project description:
Hypothesis: If a toothpaste has the ingredient Triclosan added to it, then the bacteria in the
mouth will be destroyed more than when toothpastes without Triclosan are used.
Scientific Principles: Triclosan is highly-effective antimicrobial agent that is incorporated into a
wide array of household products such as deodorants, soaps, fabrics, and mouthwashes. It has
been found to inhibit an enzyme involved in fatty acid synthesis, which is necessary for bacterial
growth. However, some scientists believe that Triclosan is not safe and claim that it has a similar
molecular structure and chemical formula as some of the most toxic chemicals on earth.
Furthermore, other experts feel that this chemical does not, in fact, aid in killing oral bacteria.
Nonetheless, Triclosan has been approved by the FDA to be used for oral care purposes,
especially in toothpaste. Together with fluoride, Triclosan has been shown in various clinical
studies to prevent tooth decay, plaque, and gingivitis.
Materials/Methods: 12 volunteers were given 1 or 4 types of toothpastes and a new toothbrush.
Volunteers, whose last dental cleanings were within a similar time frame, were instructed how to
brush for 20 days. A control volunteer refrained from brushing for the same period. Each
participant than had his teeth scraped with a professional dental tool; samples were placed in
labeled agar prepared Petri dishes. The dishes were placed under a lamp to promote bacterial
growth. Bacterial growth was measured every day, and photographs were taken every other day
for a 28 day period. All the data was compiled and conclusions were drawn.

The Effects of PointsourceTM (a
Synthetic Insect Growth
Regulator) on Tribolium
Species
NAME
Christopher Callen
Project Description:
Synthetic insect growth regulars (IGR) have been marketed for use as a nontoxic method of
controlling cockroaches. The purpose of this project was to test the effectiveness of
PointsourceTM , a synthetic form of the IGR hydroprene on Tribolium species, common pests of
food and grain storage facilities. Two and three week old larvae of both malathion-sensitive
(Black) and malathion-resistant (Georgia) stran of T. castaneum and of T. confusum were
separated into Petri dishes and placed in seven gallon boxes with a PointsourceTM wick, and kept
at 22ºC and 30°C. Experimental and control groups were compared once a week. Exposure to
PointsourceTM resulted in an average of 10% and 32% of larvae progressing to the pupae stage at
30°C and 22°C respectively. Of these pupae, an average of 72% had twisted wings and flat,
extremely dark bodies. Deformities were more severe for the initially younger larvae. There
were no adult emergences in the experimental groups as compared to 100% adult emergences in
control groups. No significant differences were noticed between the three types of beetles but
temperature differences did affect the life span. In the experimental groups, larvae lived eight
weeks at 30ºC and twelve weeks at 22°C. PointsourceTM is effective in preventing adult
emergencies in both species and strains tested. However, it does not quickly eliminate larval
infestation, so it may not be useful to food and grain storage facilities when used alone.
