Filming participants as they brush their teeth might help teach oral healthcare techniques, according to a recent pilot study published in the Indian Journal of Dental Research.
Prior to the study, participants' tooth-brushing habits were assessed and corrected. During the study, participants used smartphones to film themselves brushing at home. These videos were later scored based on various oral healthcare techniques, such as brushing in a circular motion.
Here's what you need to know:
1. The researchers saw an 8 percent improvement in oral healthcare skills, including improvements in the accuracy and number of brush strokes.
2. However, the length of time participants brushed their teeth did not change during the experiment.
3. The researchers suggest that the act of recording may have led to these improvements, since participants might be more conscious of their habits while being evaluated.
