“ Dental Sigma ” is the name of a new soup-strainer from Vivatec of Japan , skylark crapper bowl brush - like round cleaning head . Each bristle of the brush has a diameter between 0.09 and 0.13 mm , so between this and the 360 degree head , you have a total of over 10,000 bristle ( more than 10x that of a normal brush , or so the revue suppose ) . Ending the day of having to worry about what focal point your toothbrush is pointing , the Dental Sigma evidently has some “ ease of use ” feature . After chance out how to utilise the damn affair , the reviewer of Dental Sigma indicated getting a nice and thorough brushing was a no - brainer . Now all it needs is some batteries to whirl it around at 10,000 rpm .
