Summary – What is the Central Stop Zone (CSZ)?

The Central Stop Zone (CSZ) is the area inside of the Peripheral Seal Zone (PSZ). It is the area over the pulp, encircled by the PSZ, where partial caries and crack removal is indicated in order to avoid pulp exposure.

Note that complete caries and crack removal is being carried out in the PSZ, whereas Caries Detector Dye is still staining areas within the CSZ. In this area, partial caries/crack removal is indicated in order to avoid pulp exposure.
