Areas of an eosinophilic matrix material that are considered by some authors to represent dentinoid also may be present adjacent to the epithelial component.
Extensive areas of eosinophilic matrix compatible with dysplastic dentin (dentinoid) were found in the fibrous capsule (Figures 3(d)-3(f)).
In the present case, it was possible to observe a prominent and extensive presence of dentinoid in the fibrous capsule.
It has been demonstrated that DPSC grafted on a hydroxyapatite framework under the skin of a mouse produce
dentinoid tissue containing type 1 collagen.
The dentin may vary structurally from
dentinoid to tubular dentin.
The lesions exhibited calcifying elements (dentin matrix and
dentinoid material).
Clear cell odontogenic tumor in the mandible: Report of a case with duct-like appearances and
dentinoid induction.
Primary intraosseous odontogenic carcinoma with osteoid /
dentinoid formation.
The calcifications seen in these cysts, which represent attempts of the root sheath epithelium to induce root dentin, have been identified as
dentinoid material.
Odontogenic ghost cell carcinoma displays, in addition to a malignant epithelial component, the classic features of calcifying cystic odontogenic tumor, including the presence of ghost cells and
dentinoid materials, which are completely absent in PIOSCCs.
Induction of hyaline, dysplastic
dentinoid material or calcified osteodentin has been described.
In the primary tumors of cases 4 and 5, eosinophilic hyaline deposits reminiscent of osteoid or
dentinoid structures were formed within the connective tissue stroma in direct contact with the epithelial nests (Figure 5).
