Scanning electron microscopic observations of fibrous structure of cemento-dentinal junction in healthy teeth

The objective of this study is to observe and report the fibrous architecture of the CDJ of healthy tooth roots.
Materials and Methods: A total of 15 healthy teeth samples were collected, sectioned into halves, demineralized in 5% ethylenediaminetetraacetic acid, processed using NaOH maceration technique and observed under a scanning electron microscope.
Results: The CDJ appeared to be a fibril poor groove with a width of 2-4 µm. Few areas of collagen fiber intermingling could be appreciated. A detailed observation of these tissues has been presented.
