Which histological changes indicate over decalcification?

Over decalcification happens when the decalcifying agent is too strong or used too long. The acid not only removes calcium but also damages tissue proteins and nucleic acids. This leads to loss of nuclear detail because chromatin and nuclear structures are degraded, so nuclei lose their sharp appearance under the microscope. The tissue can also appear swollen as cell membranes and the surrounding matrix are disrupted by the acid. These changes are characteristic of excessive decalcification. In contrast, increased nuclear detail would not be expected with over-decay; it may occur if decalcification is insufficient or if fixation preserves nuclei well. Unchanged staining suggests proper decalcification, and hypergranulation is a wound-healing tissue change, not a sign of decalcification status.
