Root formation begins when which of the following occurs?

Question

Quizplus · Accepted Answer

Root formation begins when the epithelial root sheath proliferates and starts to form the Hertwig's root sheath. This will later induce the differentiation of the dental papilla cells into odontoblasts, which deposit dentin and begin the formation of the root. Factors such as the tooth's crown entering the oral cavity or the surrounding fibrous tissue increasing may contribute to the overall development of the tooth, but they do not directly initiate root formation. Similarly, the contact and fusion between the reduced enamel epithelium and the oral epithelium occurs later in the dental development process and is not necessary for root formation.
