Ultrastructural study of odontoblasts of dental pulp in the cells aging process.

Odontoblasts located in the peripheral layer of the pulp reflect current state of the process connected with the formation of the secondary dentin and thereby they protect teeth from inflammatory processes (1, 3, 4, 6, 10). Odontoblasts are highly specialized cells that can react to the mechanical, thermic and toxic and bacterial traumas (12, 13, 14, 15).
