Mechanism of Human Tooth Eruption: Review Article Including a New Theory for Future Studies on the Eruption Process

Figure 12

Three immunohistochemical sections of NeuN (nerve tissue markers) shown on otherwise uncoloured sections. D marks the dentin. Left: normally developed root surface (brown nerve cells) [89, 103]. Right: two sections of tooth root surfaces from teeth extracted due to arrested eruption. Upper: root dentin covered in hypercementosis-like tissue formations. Below: an unorganized pattern of dentin and bone tissue with nerve markings. It must be presumed that the very uneven surface dentin in the two images to the right is caused by resorption and that the resorption lacunae are later filled with tissue with osteogenic potential.
