Examples
Still, it can easily be renewed, or if all the tin is removed we find the dentin hard and firm.
Nature will not restore the lost part, but will do the next best thing—solidify the dentin.
In some cases, under tin, the pulp gradually recedes, and the pulp-cavity is obliterated by secondary dentin.
The effect is to cause the surface exposed to dentin to oxidize more than tin would do alone; in that there is a benefit.
