Oxytocin causes contraction of the myoepithelial cells surrounding the mammary alveoli, which presses milk into the larger ducts and leads to the milk let-down reflex. This is essential for milk ejection during lactation.

Factors that can lead to tooth discoloration following a large amalgam filling include the bonding to dentin, the time of application of materials, and the removal of the smear layer. "Technique sensitive and expensive" is not a biological or chemical factor in the discoloration process itself, but rather a characteristic of a different dental procedure.

Physiology
Chymotrypsin is an endopeptidase enzyme that plays a crucial role in the digestive system by breaking down proteins into smaller peptides. It is activated from its precursor chymotrypsinogen by the enzyme trypsin. Once active, chymotrypsin hydrolyzes the peptide bonds at the carboxyl side of aromatic and bulky amino acids, such as phenylalanine, tryptophan, and tyrosine. This process is essential for the further digestion and absorption of dietary proteins.

Primary prevention involves intervening before a lesion occurs to
prevent the disease from developing. This includes actions like brushing with
