The researcher examined a thin slice of dentine under the microscope to observe the tubular structure.

Under the microscope, the dentines showed varying patterns of tubules and mineralization across the sample.

When the enamel wore away, the exposed dentin became sensitive to hot and cold.

The dentist prescribed a treatment to address dentinal sensitivity caused by enamel erosion.

The adhesive bonded dentinally to the inner surface of the cavity, improving retention in deep restorations.

Microscopic examination revealed that the dentins varied in mineral density across different regions of the tooth.
