[Effect of EDTA and hyaluronic acid on the activity of periodontal ligament fibroblasts and the expression of cytokines].

Purpose: To investigate the effect of ethylenediaminetetraacetic acid (EDTA) and hyaluronic acid (HA) on the activity of periodontal ligament fibroblasts (PDLFs) and the expression of cytokines.

Methods: Twelve wisdom teeth extracted due to orthodontics treatment were selected and prepared into 5 mm×4 mm root pieces, then divided into EDTA group, HA group, EDTA+HA group and untreated group according to different treatment methods. They were placed in the well plate and PDLFs inoculated on the root piece.

Pathway analysis of a genome‑wide association study on a long non‑coding RNA expression profile in oral squamous cell carcinoma.

Long non‑coding RNAs (lncRNAs) have been consistently demonstrated to be involved in oral squamous cell carcinoma (OSCC) as either tumor oncogenes or tumor suppressors. However, the underlying mechanisms of OSCC tumorigenesis and development have not yet been fully elucidated. The expression profiles of mRNAs and lncRNAs in OSCC were analyzed by a microarray assay.

Role of the Chinese herbal medicine xianhuayin on the reversal of premalignant mucosal lesions in the golden hamster buccal pouch.

Aim: To investigate the role of the Chinese herbal medicine Xianhuayin on the reversal of 7,12-dimethylbenz[a]anthracene (DMBA)-induced premalignant mucosal lesions in the oral buccal pouch of golden hamsters.

Methodology: The animals were randomly divided into a non-diseased control group (n=5) and an experimental group including 50 animals in which the buccal mucosa had been painted with DMBA (0.5% in acetone) to generate an oral mucosa premalignant lesion.
