Efficiency of dry versus wet Er,Cr:YSGG laser debonding of lithium disilicate veneers using different power outputs.

Statement Of Problem: Since water is the chromophore for the erbium, chromium-yttrium scandium gallium garnet (Er,Cr:YSGG) laser, the laser energy reaching the restoration decreases as part of it is absorbed by water. Theoretically, reducing the water or implementing dry debonding could reduce the energy consumed by water, increasing laser efficiency. Studies on whether it is suitable for removing veneers without using coolant are lacking.

Integrated Biomarker Response Emphasizing Neuronal Oxidative Stress and Genotoxicity Induced by Oxamyl in Sprague Dawley Rats: Ameliorative Effect of Ginseng as a Neuroprotective Agent.

Climate change has led to increased and varying pest infestation patterns, triggering a rise in pesticide usage and exposure. The effects of oxamyl, a widely used nematicide in Egypt, encompasses typical signs of carbamate intoxication; nevertheless, long-term effects of oxamyl exposure, particularly on the nervous system, require further elucidation. This study systematically investigated the mechanism and manifestations of repeated subacute exposure to sublethal doses of oxamyl in male SD rats.

Marriage in displacement: Gendered (self)resettlement strategies of Syrian women in Egypt.

Drawing on fieldwork data among Syrian refugee women marrying Egyptian men amid forced migration, I explore how displacement reshapes the meaning and purpose of marriage. Many such unions, often customary or polygamous, provoke comparisons to forced marriage and gender-based violence. Bypassing the reductive exploitation and static narratives, I ask: How does displacement alter refugee women's perceptions of marriage's purpose? And can marriage serve as a strategic tool for (self)resettlement? This investigation urges us to reevaluate the existing range of resettlement options and criteria, offering fresh perspectives on marital strategies post-displacement.

Trueness and intaglio fit of custom-made polyetheretherketone post-and-cores fabricated using different techniques.

Statement Of Problem: Applications of polyetheretherketone (PEEK) as a promising alternative to ceramic materials have extended to include post-and-cores. However, information regarding the available fabrication techniques for producing custom-made PEEK post-and-cores and their effect on accuracy is still scarce.

Purpose: The purpose of this in vitro study was to evaluate the trueness and intaglio fit of custom-made PEEK post-and-cores fabricated using different techniques.
