Role of Attrition and Occlusal Contact in the Physiology of the Rat Incisor: VI. Impeded and Unimpeded Eruption in Hypophysectomized and Magnesium-Deficient Rats

Abstract

Eruption, attrition, and crown length were measured in impeded and unimpeded rat incisors in hypophysectomized and magnesium-deficient rats. The rate of unimpeded eruption was twice the rate of impeded eruption; this proves that the rates of eruption and attrition are determined by the amount of occlusal contact and the condition of the periodontal ligament.
