Before the start of the cavity preparation, the occlusal enamel was removed up to Dentinoenamel
Junction (DEJ) under the running water with the diamond saw to expose a flat superficial dentin.
The enamel prisms of permanent teeth have an orientation essentially parallel to the dentinoenamel
junction except for the cervical enamel where the prisms are oriented towards the exterior with an apical direction.
High-resolution electron-microscopic study of the relationship between human enamel and dentin crystals at the dentinoenamel junction.
Synchrotron microcomputed Tomography of the mature bovine dentinoenamel junction.
Dentinoenamel Junction Area of a Resorbing Permanent Incisor Studied by Means of Scanning Electron Microscopy.
A comparative analysis of the structure of the dentinoenamel junction in mammals.
It is crossed by tubules that extend from the pulp to the dentinoenamel
Mechanical properties of the dentinoenamel
junction: AFM studies of nanohardness, elastic modulus, and fracture.
Otherwise, the dentinoenamel
junction (DEJ) could not be clearly depicted.
Digital radiography was used to classify the teeth into approximate caries classifications of: 30% teeth with no carious lesions, 25% teeth with carious lesions confined to the enamel, 25% teeth with carious lesions reaching the dentinoenamel junction, and 20% teeth with carious lesions extending into the dentin.
Carious Lesion Classification--Four-Point Scale 0 = no carious lesion 1 = carious lesion restricted to the enamel 2 = carious lesion reaches the dentinoenamel junction 3 = carious lesion extends into the dentin Table IV.
