Resumo
Foi realizado um estudo, pela microscopia eletrônica de varredura, de seis marcas de escovas dentárias, fabricadas no Brasil, novas ou após o uso em pacientes com e sem cálculo supragengival. As escovas novas, de uma das marcas, apresentaram-se dentro das especificações quanto ao arredondamento das pontas das cerdas. Todas as escovas usadas por pacientes portadores de cálculo apresentaram suas condições totalmente deterioradas.
Palavras-chave

Abstract
A SEM study was made to test the conditions of the bristles of six different types of toothbrushes made in Brasil. They were either brand-new or used by patients with or without supragingival calculus. Just one kind of the toothbrushes fitted into the specifications as concerned to the roundishness of bristle points. All the toothbrushes used by patients with calculus showed their bristles entirely spoiled.
