Smooth surface caries is on a surface that does not have pits, fissures. Usually on the front, back, or side of the tooth as opposed to the top where there are hills and valleys so to say. If the caries is on the crown part of the tooth it started on the enamel, but may have progressed down to the dentin which is the next surface under the enamel.
enamel caries: surface zone, body of lesion, dark zone, translucent zone dentinal caries: desrtuction, penetration, demineralisation, sclerotic dentine enamel caries: surface zone, body of lesion, dark zone, translucent zone dentinal caries: desrtuction, penetration, demineralisation, sclerotic dentine
Whenever the spread of caries along the dej exceeds cone in enamel, the caries extends into the enamel from the junction
dentin is less minerelised than enamel thus it is soft
Dental enamel
Dentin is the material of your teeth that is under the enamel.
The crown is made up of enamel which is the hardest tissue in the body. Under the layer of enamel is dentin which gives enamel its color. Dentin is softer than enamel. Underneath the dentin layer are pulp horns and pulp chambers.
they are enamel(outer covering), dentin (middle ) , and pulp (inner most).
Below the enamel is the dentin or dentine you can call it one of those two it duznt matter and the dentin/dentine is between the cement and enamel.(below the enamel , on top of the cement.)

The dentin is under the enamel.
Hypocalcified structures-enamel lamellae,enamel tufts,enamel spindle,striae f retzius and neonatal line
