Tooth Eruption: Axial Movement of Teeth with Limited Growth

Our knowledge of tooth eruption is still in a hypothetical stage. It was felt that only a more detailed and minute histological investigation of erupting teeth could possibly lead to an understanding of this complicated phase in tooth development. It seemed promising to attack this problem by: first, investigating specialized teeth in which the eruption is, in a sense, simplified; such teeth are the continuously growing and erupting teeth. Second, only one component of the complicated movement of erupting teeth should be studied; the most obvious movement is the axial movement. For this reason the first study on eruption dealt with the axial movement of continuously growing teeth only (6). The purpose of this second paper on eruption is to study the axial movement of teeth with limited growth.

Tissue reaction in surgical defects of the palate in Macaca rhesus

Abstract The present study is based on the gross and microscopic examination of the palates of two growing monkeys in which a unilateral cleft was produced surgically. There is marked proliferative activity at the edges of the surgical cleft, leading in some areas to a functional closure.
