Theory

lesion of the gingiva that results from mechanical removal of the surface epithelium

loss of tooth structure produced by a mechanical cause (such as a hard-bristled toothbrush used with excessive pressure and a an abrasive dentifrice); _____ contrasts with erosion, which involves a chemical process

individual short, stiff, natural hair of an animal; historically, toothbrush bristles were taken from a hog or wild boar, but current toothbrush ______ are made of nylon and are called filaments

characteristic shape of each toothbrush filament; a special manufacturing process removes all sharp edges and provides smooth, rounded ends to prevent injury to gingiva or tooth structure during use

individual synthetic fiber; a single element of a tuft fixed into a toothbrush head

a nylon filament that is placed in the brush head at an angle

oral hygiene methods for removal of dental biofilm from tooth surfaces using a toothbrush and selected devices for interdental cleaning; contracts with chemotherapeutic bioflim control in which an antimicrobial agent is used

a brush driven by electricity or battery; also called power assisted, automatic, electric or mechanical (incontrast with manual)

a term used to describe a power toothbrush that operates in the audible range of human hearing

the reaction force exerted per unit area of the brush during deflection; the term ______ is used interchangeably with firmness of toothbrush bristles or filaments; the stiffness depends primarily on the length and diameter of the filaments

a method in which the end-round filament tips are directed into the gingival sulcus at approximately bioflim from both the gingival sulcus and the tooth surface just below the gingival margin

the part of the toothbrush composed of the tufts and the stocks (extension of the handle where the tufts are attached)

a cluster of bristles or filaments secured together in one hole in the head of a toothbrush
