What is the first radiograpgic evidence of proximal caries?

a dimple on the outer surface of the enamel

When the entire thickness of the enamel is involved, the lesion seems to be linear or triangular with the apex toward the ______

after the decay has traveled along the amelodentinal junction, it travels towards the ____

pulp

when the decay travels towards the pulp it also conforms towards what shape initially

triangle

after the triangular shape has been formed into the pulp it spreads _______

If one tooth is involved proximally, what else is involved?
