Glycol methacrylate is commonly used on what type of tissue?

• A. Undecalcified bone
• B. Soft tissue
• C. Calcified bone
• D. Teeth

Answer: (A)

Glycol methacrylate is chosen when you need to study mineralized tissues in their native state. It’s an acrylic resin that infiltrates and hardens undecalcified bone, allowing very thin sections to be cut without removing minerals. This preserves the fine architecture of the bone matrix, including osteoid seams and mineralization fronts, so you can accurately assess bone morphology and remodeling. Because the tissue isn’t decalcified, you can apply stains and histochemical methods that depend on the mineral content.

Soft tissues are typically processed for paraffin embedding, where decalcification isn’t an issue and routine sectioning suffices. Teeth can be examined with glycol methacrylate too, but the most characteristic and common use cited is for undecalcified bone, where preserving mineral content is essential for accurate analysis.
