Besides the risk of filling material extrusion throughout the apex, a satisfactory apical seal can be difficult to achieve in canals with open apices or iatrogenic enlargements of the apical constriction. These situations pose a challenge to root canal filling. This paper describes the root canal filling of a maxillary right canine with an overinstrumented apex, complete loss of the apical stop...
signaling to orchestrate cell shape changes during mesoderm invagination. The apically targeted transmembrane protein T48 acts as an anchor for RhoGEF2 via a PDZ binding motif and thereby ensures the apical enrichment of RhoGEF2 during mesoderm invagination allowing rapid and efficient ventral furrow formation. Apical constriction also requires the tethering of the contractile network to the ad...
