What causes neonatal line?

What causes neonatal line?

Background: The neonatal line (NL) is an important issue in forensic odontology. It is the sign of a developmental birth defect, which is caused by the effect of metabolic stress on tooth structures when the fetus passes to extrauterine life.

Is neonatal line a Hypocalcified structure?

The neonatal line formed by the double bending of the prisms is likely to represent a particular type of rhythmic Retzius line rather than a pathologic Retzius line, whereas the hypocalcified sheath regions may be similar to those of some pathologic lines of Retzius.

What are neonatal teeth?

85% of the cases), the natal or neonatal teeth are the deciduous mandibular incisors. In almost 90% of the cases, the teeth are of the normal deciduous complement. The rest are supernumerary. In about 60% of the cases, both of the natal and/or neonatal mandibular incisors erupt prematurely.

What is dental Perikymata?

Perikymata are wavelike features that are normally found in the surface enamel of teeth. These structures are known to undergo regressive changes due to gradual attrition, mechanical abrasion, or chemical erosion.

What is the meaning of the neonatal line?

The neonatal line is a particular band of incremental growth lines seen in histologic sections of both enamel and dentine of primary and permanent teeth. It is made partly after birth. It belongs to a series of a growth lines in tooth enamel known as the Striae of Retzius. The neonatal line is darker and larger than the rest…

How are lines and tubes used in the NICU?

Neonatal lines and tubes are widely used in the NICU (neonatal intensive care unit) in the management of critically ill neonates. Examples include: The NG tube serves the function of providing parenteral nutrition and a route for suction if needed.

Where do you find the neonatal line in your teeth?

The neonatal line is a particular band of incremental growth lines seen in histologic sections of both enamel and dentine of primary and permanent teeth. It is made partly after birth.

Is it normal for a newborn to have linea nigra?

It is a fairly common finding in newborns, especially those with more pigmented skin. The presence of linea nigra seems to be impacted by hormonal levels, as this finding is often seen is pregnant women as well. It is completely benign.
