Mesial surface – towards the front of the mouth
Caries are an infectious, communicable disease resulting in the destruction of tooth structure by the acid produced by the metabolism of sugar by bacteria found in dental plaque
Plaque is a dense bacterial aggregate containing about 10% bacteria per milligram that accumulates on tooth surfaces.
The acid created by the caries bacteria’s metabolism of sugar leads to demineralization. Demineralization is the loss of calcium, phosphate and carbonate from the enamel
Lesion is progressing laterally and towards the pulp
Lesion has reached the dentinoenamel junction (DEJ)
(caries not more than halfway into enamel)
Lesion extended into the pulp
If demineralization is allowed to continue, the tooth will eventually be eroded enough for a cavity to form.
