In vitro evaluation of the effects of frequently prescribed pediatric drugs on the microhardness of permanent tooth enamel.

Background: Dental erosion is considered one of the oral cavity diseases. Frequent intake of liquid oral medications can be an effective factor in tooth erosion.

Objectives: This study aimed to evaluate the effects of frequently prescribed pediatric drugs on the permanent dental enamel microhardness over a period of 14 days in vitro.

Preventive and protective effects of Turkish propolis on H₂O₂-induced DNA damage in foreskin fibroblast cell lines.

The aim of the present study was to evaluate the potential of Turkish propolis extracts if they prevent or protect foreskin fibroblast cells against hydrogen peroxide (H₂O₂)-induced oxidative DNA damage. Hydrogen peroxide (40 μM) was used as an inducer of oxidative DNA damage. The damage of DNA was evaluated by using the alkaline single cell gel electrophoresis (comet) assay.
