Microleakage of Different Pit and Fissure Sealants

Sealing pits and fissures is considered to be an effective way of preventing caries initiation. The present in vitro study was carried out to evaluate the microleakage and sealing ability of Helioseal F, Seal-it and GCP Glass seal and Compared sealing ability of GCP Glass seal with resin fissure sealants. The present study represents an attempt to detect and compare the microleakage of three dental fissure sealants.

Estrogen Ameliorates Photoreceptor Cell Loss In Light-Induced Retinal Degenerated Balb/C Mice

Estrogen or 17β-estradiol (17β-E2) is known to act as an antioxidant and has neuroprotective effects. The purpose of this study is to evaluate the effects of estrogen and estrogen receptor beta (ERβ) on photoreceptor cell structure and function in an experimental model for light-induced photoreceptor degeneration. Light-induced retinal degeneration is widely accepted to study the … Continue reading Estrogen Ameliorates Photoreceptor Cell Loss In Light-Induced Retinal Degenerated Balb/C Mice
