introduction: in different investigations, the destructive effect of ultrasonic scalers on the margins of composites has been studied, but there are very few studies on the effects of ultrasonic scalers on the microleakage of poly-acid modified composite resin and resin modified glass ionomers. the main purpose of this study was to evaluate the marginal microleakage of class v preparations rest...
This study presents a novel technology, termed thermomorphic hydrophilicity base-induced precipitation (THBIP), for the effective removal of hardness ions from hypersaline brines with high-scaling propensity. THBIP utilizes thermoresponsive amine bases controlled scaling constituents in alkaline conditions and subsequently uses low-temperature heat to trigger phase separation aqueous solution, ...
Ichthyosis is defined as a group of diseases with keratinization disorder and diffuse scaling with highly variable degree of involvement. According to our knowledge, coincidence of ichthyosis and dermatophytosis, which both are very common disorders, is a very rare event. We report a young man with congenital ichthyosis that histological analysis of his skin biopsies and direct smear revealed P...
