Objectives
Collagen fibrils from carious dentin matrix are prone to enzymatic degradation. This study investigates the feasibility and mechanism of nordihydroguaiaretic acid (NDGA), as a collagen crosslinker, to bio‐modify the demineralized dentin matrix.
Methods
The physicochemical properties of the crosslinked dentin matrix were characterized by swelling ratio, ninhydrin assay, Fourier Transform...
Objective
To evaluate the relation between the expression of PD‐1, PD‐L1, CD3, CD8, Foxp3 and clinicopathological features in patients with oral leukoplakia (OLK) and oral squamous cell carcinomas (OSCC) as well as the malignant outcome in OLK patients, and to study the effect of PD‐1 and PD‐L1 on immune microenvironment in the progression of oral carcinogenesis.
Methods
We evaluated the expression...
