Each of these structures has a uniquely shaped pulp chamber, which when inflamed must be addressed with root canal therapy.
A cell that serves as a developmental precursor to these structures appears to have a "picket-fence" morphology due to Tomes' projections. Pits called perikymata indicate the termination of incremental lines known as Striae of Retzius in a constituent tissue of these structures, whose basic units are called either prisms or rods. As these structures develop, the inner epithelial layers abutting the cervical loop disappear, creating a structure named for Oskar Hertwig. Four numbers separated by periods appear in both the numerator and denominator of a (*) "formula" used to quantify these structures. The process by which these structures become visible is termed their "eruption." The alveolar bone connects to these structures by a set of tissues that includes the cementum. Each of these structures has a uniquely shaped pulp chamber, which when inflamed must be addressed with root canal therapy. For 10 points, name these enamel-covered structures used by vertebrates to chew and bite food.
