description | any structural anomaly of the pyramidal extension at the apical pole of a secretory ameloblast that plays an important role in organizing the enamel crystals into a complex network of rod (prism) and interrod enamel; Tomes' processes interdigitate with the surface of the forming enamel giving it a picket fence appearance and determine the orientation of the newly formed (nucleated) enamel hydroxyapatite crystals; as the secretory stage ends, Tomes' processes are lost and accordingly the last formed layers of enamel are rodless or prismless |
