dictum but there is little evidence that
infected dentine must be removed before
sealing the tooth with a restoration.17–19
Conversely, there is now a substantial evidence
base from long-term studies that
caries lesions that are sealed in place do
not progress and might even regress.11,20–22
This is consistent with the principles of
therapeutic sealing since if cariogenic
bacteria are isolated from their source of
nutrition they either die or remain dormant
and therefore cannot result in caries
lesion progression
