Enhancing Histological Visualization of Tooth and Bone Ground Sections Using Terminalia chebula Stain: A Comparative Analysis

The Scientific World Journal, Volume 2026, Issue 1, 2026.
Background Visualization of mineralized tissues such as tooth and bone in ground sections is widely used for histological studies. However, unstained ground sections often provide limited contrast and obscure microscopic details. Natural plant‐based stains have been explored as cost‐effective and safer alternatives to synthetic dyes. Terminalia chebula,
