Maharishi School ninth grader Pranav Chhalliyil continues to collect awards for his science project on oral health.
In addition to winning the top award in the junior division at the state science fair last spring, his project was selected as the best in Iowa by the Discovery Education 3M Young Scientist Challenge, a major national science competition that entails creating and submitting a video in which the student presents his or her project.
Mr. Chhalliyil's study involving 88 subjects sought to identify the best cleaning methods for oral hygiene.
He tested eight methods by performing one type of cleaning and then measuring the amount of bacteria in the mouth the next day. He found that the two best methods were teeth brushing plus tongue cleaning, and finger rubbing plus water swishing.
He said that the latter approach is ideal for developing countries because it is easy, convenient, and cost effective.
He was also among the 300 semifinalists in the Broadcom MASTERS national science competition that were selected from the 60,000 students who participated nationwide. He plans to continue research on the role of oral cleansing.
