Intracellular complex carbohydrates in the normal and inflamed dental pulp.

Abstract

abstract— Forty‐four inflamed pulps from human and monkey teeth were studied using histochemical staining methods. In pulps from carious human teeth, mast cells and many fibroblasts containing glycogen‐like granules were regularly observed. In monkey pulps, where pulpitis was induced experimentally, mast cells were found only occasionally, and glycogen‐like granules were absent. However, some fibroblasts in normal and inflamed monkey pulps contained periodic acid‐Schiff (PAS) positive granules, which were resistant to amylase. Such granules were not found in human pulp fibroblasts.
