Role of Attrition in the Physiology of the Rat Incisor. I. The Relative Value of Different Components of Attrition and Their Effect on Eruption

Abstract
The various components of attrition compensated for each other so that the sum total remained the same under the varying experimental conditions indicating that the eruptive process is a primary factor, and attrition has to remove the extruded tooth substance for the survival of the individual. Semi-starvation had no effect on the rates of eruption or attrition of the rat incisors.
