The formation of Hertwig's Epithelial Root Sheath (HERS) is crucial in determining the shape, length, and number of roots in teeth. It initiates the formation of radicular dentin, marking the beginning of root development after enamel and dentin formation. HERS consists of outer and inner enamel epi

Root formation plays a crucial role in the development of teeth, starting after enamel and dentin formation at the cementoenamel junction. Hertwig's epithelial root sheath (HERS) molds the shape of roots, initiating radicular dentin formation. The cervical loop forms an epithelial diaphragm, narrowi
