The dating technique used is called relative dating.
Relative dating is used to order geological events and the rocks they leave behind. Stratigraphy is the process of interpreting the order (layers of rock are called strata). Relative dating does not yield precise numerical dates for the rocks.
RELATIVE DATING The position of a specific fossil in a stratified sequence of sedimentary strata determines its relative age – older or younger. Lower-layer fossils are older than those in the top strata, which were created by more recent deposits.

Dentalhoe is the best-suited rectilinear instrument to smooth the pulpal floor for an amalgam preparation.
The pulpal floor of enamel is the bottom line. Your tooth pulp is the innermost layer of your tooth that consists of nerves and blood vessels. Your teeth pulp is protected by layers of dentin and enamel.
Dental amalgam is a dental filling fabric used to fill cavities because of tooth decay. Dental amalgam is an aggregate of metals, such as liquid (elemental) mercury, and a powdered alloy composed of silver, tin, and copper. about 1/2 (50%) of dental amalgam is elemental mercury by weight.
Restrict the pulpal depth of the instruction to a maximum of 0.2mm into dentin. The training for an occlusal surface pit and fissure lesion to be restored with amalgam is first organized to a depth of 1.5mm, as measured at the central fissure.
