[The finishing of the bristle ends in interdental brushes].
The result of a scanning electron microscopic study of fourteen interdental brushes, available on the German and Swiss market, was that all products have an insufficient finish of bristle ends. Only one brush showed 17.3% of acceptably rounded bristle ends. In addition, the unacceptable rounded bristle ends were classified, corresponding to their variation of form. The results allowed to estimate the degree of damaging potential of the periodontal tissues, using interdental brushes.
