Dentin Softened

Softened dentin is dentin with a reduced content of mineral salts, located at the bottom of the carious cavity.

With dental caries, demineralization of the hard tissues of the tooth, in particular dentin, occurs. Due to a decrease in the content of minerals such as calcium and phosphorus, dentin becomes less dense and softer.

Softened dentin has a characteristic yellowish-white color and soft consistency. It is easily removed with an excavator, unlike healthy hard dentin.

Softened dentin is usually found in the deepest part of the cavity, directly above the pulp of the tooth. This is the most caries-affected layer of dentin in front of the pulp. Softened dentin needs to be carefully removed during caries treatment to prevent inflammation of the dental pulp.

As a radiological phenomenon, the dentinal lattice is not a full-fledged independent radiolucent material, but a layer of mineral salts on the surface of the root. All doubts regarding the X-ray opacity of the root are removed when examined under normal conditions, since the coronal part of the tooth is normally passable.

Why is it considered necessary to reduce X-rays? Because many gnathostomes are located far from the root, it is difficult for them to assess the condition of the cortical bone and hypodense layer. For students to study the dentinal membrane, it is necessary to use a standard gnathone-projection with translation, which will speed up the receipt of qualified reports on gnathonemas and, accordingly, improve the quality of training.
