Effect of soaking in Hank's balanced salt solution or milk on PDL cell viability of dry stored human teeth.

This study was designed to evaluate the effect of soaking in either Hank's balanced salt solution (HBSS) or milk on periodontal ligament (PDL) cell viability in avulsed teeth. Dry storage times of 30, 60, and 90 min were evaluated. PDL cell viability was determined after removal of the cells from the root surfaces of extracted teeth using a modification of the procedure described by Nakashima (Arch Oral Biol 1991;36:655-63).

Hormonal modulation of herpes simplex virus replication in a mouse neuroblastoma cell line.

In this study, the effect of the synthetic glucocorticoid hormone dexamethasone (DXM) on HSV replication was studied in a DXM receptor-positive mouse neuroblastoma (NB) cell line. In cells treated with 10(-7) M DXM and then infected with HSV, there was a statistically significant 9-18-fold increase in the amount of virus produced in these cells compared to untreated controls. Adsorption kinetic studies with HSV were performed in DXM-treated NB cells and untreated controls.

Determining periodontal ligament (PDL) cell vitality from exarticulated teeth stored in saline or milk using fluorescein diacetate.

One of the key factors for obtaining a favourable long-term prognosis in avulsed teeth is maintenance of the vitality of the periodontal ligament (PDL) cells. Most studies which have examined PDL cell vitality have used neutral red or trypan blue as stains. However, these stains have certain inherent disadvantages.

Permeability of latex gloves after contact with dental materials.

The use of latex examination gloves in the dental office has become the standard of care. However, the effectiveness of gloves as a barrier after coming into contact with specific dental materials is still uncertain. To examine the effects of dental materials is still uncertain.
