(Apr 28, 2022) — Faculty and students in Kennesaw State’s Southern Polytechnic College of Engineering and Engineering Technology (SPCEET) are doing research that will lead to better oral health for children, by
studying fluoride varnish applications.
“I’ve always been passionate about doing research that helps society,” said principal
investigator and department chair of industrial and systems engineering (ISYE) Christina Scherrer. “I’m excited to involve Kennesaw State students on this
project which will positively impact children in our area.”
Scherrer was recently awarded a three-year, $424,000 grant from the National Institutes
of Health (NIH), along with co-principal investigators Robert Keyser, ISYE faculty
member at Kennesaw State, and Shillpa Naavaal from Virginia Commonwealth University’s
School of Dentistry, to assess and reduce barriers associated with primary care doctors
applying fluoride varnish on children’s teeth. It is the first NIH grant to be awarded
directly to the college.
Fluoride varnish is a dental treatment that reduces decay, can be applied on primary
teeth and permanent teeth, and has the potential to dramatically improve oral health.
Insurance in every state will pay for pediatricians to apply the fluoride varnish,
but Scherrer says not very many do, citing concerns about the time it takes and cost-effectiveness.
“Children under the age of three, especially from low-income populations, may not
visit a dentist,” said Scherrer, who has also worked with the CDC on oral health research. “However, most will visit their pediatrician annually for a well-visit, which makes
it an ideal opportunity to receive fluoride varnish.”
The faculty members, along with several undergraduate student researchers, will partner
with pediatric clinics in Georgia that are applying the fluoride varnish to study
their practice. The long-term goal is to increase access to, and use of, fluoride
varnish in non-dental settings to reduce disparities in children’s oral health.
“We know that it will have a positive impact on children’s teeth if we can make it
easier for more pediatricians to add fluoride varnish application to well-visits for
young children,” said Scherrer.
Keyser, who has an expertise in time-study, will take teams of students to clinics
that are applying fluoride varnish and will videotape the application process. They
plan to take more than 100 videos, which will later be broken down and analyzed. The
time studies will determine how long each step takes, from the child sitting down
in the office, to the preparation of supplies, the application process and the paperwork
This analysis will result in documenting best practices to share with other pediatricians
who are hesitant to incorporate the important preventive oral treatment. Keyser is
excited to work with Scherrer and the students on a project that will have many positive
“The students get excited about being involved in something that not only will come
with a journal publication, but will also be real research that benefits humanity,”
Keyser said. “This is a contribution on our part to help children and their parents.”
Keyser and Scherrer are currently recruiting students to join their research team
and hope to start site visits in the summer.
“I am amazed at how our faculty continue to lead cutting-edge research that transforms
the world around us,” SPCEET Dean Ian Ferguson said. “This award showcases the unique
applications for future engineers, and our students will greatly benefit from the
opportunity to participate in this research.”
