    The notion of density of the area integral was introduced by \textit{R. F. Gundy} in 1983. This non-linear functional is related to the Littlewood-Paley theory. The authors prove that this functional can be expressed as the principal value of a certain singular integral of the Calderón-Zygmund type.
