    Typical models of child’s mouth, aged 10, brought up in accordance with the principles advocated, without resort to any artificial aids to keep the teeth and gums clean, healthy, and free from any trace of caries, The right side (the left on this page) of each model was dipped into carmine, let dry, then brushed. This was repeated twice. The photographs indicate how imperfectly the crevices and interdental spaces of teeth are cleaned. Incidentally it may be noted that the models show a particularly perfect set of teeth without crowding and consequently relatively easy to clean. The child, one of the 14 referred to page 33, having been brought up on food requiring mastication, has worn the cusps especially of the tem- porary teeth, so that the crevices are relatively easily brushed.
