During which stage is the morphology of the crown determined?

Cap Stage
Bell Stage
Initiation Stage
Maturation Stage

The correct answer is: Bell Stage

The morphology of the crown is determined during the bell stage of tooth development. At this stage, the dental lamina has formed, and the enamel organ is fully developed, taking on a bell shape. This bell shape signifies the differentiation of the inner enamel epithelium into the ameloblasts, which are responsible for enamel production. Additionally, this stage is characterized by the development of various layers of the enamel organ, including the outer enamel epithelium, stellate reticulum, and stratum intermedium, all of which contribute to the overall shape and size of the developing crown. This significant morphological development influences not only the external appearance of the tooth but also its internal structure, as enamel and dentin formation are closely intertwined during this period. Understanding the processes occurring in the bell stage is crucial for recognizing how pathologies or irregularities in tooth development can arise.
