Abstract
Dentine of carious and noncarious teeth was examined with the electron microscope.
Distinct zones were noted at different cavity depths. A peritubular dense layer was
described and was related to the presence of microorganisms. Hypermineralized dentine
of deeper carious zones was found to be morphologically different from that of the
more superficial zones. The nature of this deeper zone was suggestive of a protective
response on the part of the tissue rather than a zone of carious destruction.
