lines of von ebner
Incremental line's in the dentin of the tooth that reflect variations in mineralization during dentin formation; the distance between the line's corresponds to the daily rate of dentin formation.

contour lines of owen
Accentuated incremental line's in the dentin thought to be due to disturbances in the mineralization process.

The striae of Retzius are incremental growth lines seen in enamel and are results of enamel's development. When viewed microscopically in cross-section, they appear as concentric rings. In a longitudinal section, they appear as a series of dark bands. The presence of the dark lines is similar to the annual rings on a tree.
Darker lines in the striae of Retzius result from systemic disturbances in the human body. For example, a fever can cause some lines to appear darker than those surrounding it. The neonatal line is the darkest band which represents the disrupted enamel formation after the stress of being born.
The formation of the striae of Retzius result from a constriction of Tomes' processes in conjunction with an increasing process of interrod enamel develop

neonatal lines
A prominent incremental line formed in the neonatal period in the enamel and dentin of a deciduous tooth or of a first permanent molar.

Incremental lines are also known as von Ebner lines.These lines reflect recurrent dentine deposition.
Contour lines of Owen are accentuated von ebner lines formed coz of disturbance in matrix formation & mineralization

Yes there is a neonatal line in dentin also.
