Histological analysis point to clefts in dental hard tissues especially dentine, marked globular dentine and increased predentin width (2,7,9).
This process describes the predentin to dentin transition in the mineralization front [22].
Tomes' observation that the pulp may have stopped the spread of the "absorptive process" indicated minimal understanding as to the nature of the process and its affinity for mineralized tissue (dentin) as opposed to non-mineralized tissue (predentin).
It also has the ability to partially neutralize the necrotic tissues or any antigenic or microbial component left in the root canal space [13] and remove all pulpal remnants and predentin on the uninstrumented surfaces [14].
This theory is based on the premise that the cementum and predentin covering on dentin are essential elements in the resistance of the dental root to resorption.
Clefts of various sizes, interglobular dentin, focally-widened predentin zones, and decreased number of dentinal tubules are prominent features of the affected dentin.44,65
Figure 1(c) showed abundant RAGE labeling observed in both odontoblastic and subodontoblastic cell layers (A and B), as well as in odontoblast processes in tubules of the predentin (A and B, arrow), stromal pulp fibroblasts-like cells (C, arrowhead), and endothelial-like cell lining in the pulpitis tissues (A and B).
However, the expression was intense in predentin and in the tissues in the resorption process.
