Mechanism of Human Tooth Eruption: Review Article Including a New Theory for Future Studies on the Eruption Process
Figure 7
Immunohistochemical images of the root-close part of the periodontal membrane on a primary tooth from a child aged 6 (left) and a permanent tooth from a child aged 10 (right). The brown colour shows positive reaction for Caspase-3 which marks apoptosis activity [100]. The inner periodontal cell layer toward the root is thus under constant cell necrosis (restructuring) during the eruption process.
