ANATOMY

Detailed explanation-1: -The first mineralized hard tissues form at this location. The adjacent layer of cells in the dental papilla suddenly increases in size and differentiates into odontoblasts, which are the cells that form dentin.

Detailed explanation-2: -Histodifferentiation refers to differentiation of cells of the enamel organ into four distinct cell groups based on their morphology and function: the inner enamel epithelium (IEE), stratum intermedium, stellate reticulum, and outer enamel epithelium (OEE).

Detailed explanation-3: -Tooth development is commonly divided into the following stages: the initiation stage, the bud stage, the cap stage, the bell stage, and finally maturation.

Detailed explanation-4: -In developing teeth morphogenetic interactions occur between the epithelium covering the facial processes and the underlying neural crest-derived mesenchyme. Morphogenesis is accompanied by differentiation of the various dental cell types, including the ameloblasts.

Detailed explanation-5: -Humans, like most other mammals, develop two different sets of dentition called the deciduous dentition (or primary dentition, baby teeth, or milk teeth), and the permanent dentition (or secondary dentition, or adult teeth).
