A group  of researchers in Japan have discovered that how effectively we clean our teeth and how satisfied we are with quality of the brushing depends on the sound of the bristles scrubbing against the enamel.  The team used a tiny microphone in a modified toothbrush to ‘sample’ the sound being made in the mouth during brushing and to modulate it and then feed that sound back to a group of volunteers via headphones to see what effect the sound has on cleaning efficacy and satisfaction. The team found that if they manipulated the pitch, or loudness and frequency, of the brushing sound they could change the volunteers’ perception of comfort experienced and accomplishment of brushing.

A study in Taiwan looked at those who have had professional tooth scraping and cleaning performed and found that they had reduced risks of stroke and heart attack. The study showed that more frequent scraping/cleaning was associated with more reduced risk compared to never having teeth cleaned/scraped or occasionally having it performed.

The people in the study were followed for an average of 7 years. The study was conducted using data from the Taiwan National Health insurance data base.
