Based on the actual scientific evidences, all non-cavitated lesions can be remineralized or sealed, even if they reached the dentin.However, since a good proportion of caries (approximately 40%) that reach the dentinal half on inter proximal X-RAYS show cavitations, and because dentinal cavities progress more quickly than enamel caries, we continue to seal dentinal caries.However, if we wish to be conservative, in theory, 60% of the caries that reach the dentinal half do not have cavitations and can be, in fact, remineralized.If we would offer the choice to the patient, I believe majority would choose remineralization treatment instead of sealings.As a reference, Efficacy of Nonsurgical Management of the
