To assess the erosive potential of dry mouth lozenges and tablets on enamel and dentin. The following lozenges and tablets were tested Salese, Oracoat Xylimelts, Cotton Mouth, TheraBreath, DenTek OraMoist, SmartMouth, ACT, CVS Health, Rite Aid, Med Active, and Hager Pharma. pH Analysis Each lozenge or tablet was crushed with a pestle and mortar and 5 g of the resultant powder was dissolved in 10 ml of distilled water (pH 7.02) The pH of each lozenge solution was assessed by using a calibrated pH meter. Titratable Acidity (TA) was determined by adding 0.1 M of NaOH to each homogenous tablet solution until the pH reached 7.0. Gravimetric Analysis was measured with freshly extracted molars crown/roots were sectioned at the CEJ and enamel and dentin specimens were fabricated. The specimens were then submerged in 5 ml of solution containing 2.5 gm of crushed tablets for 24 h, 48 h, 96 h and 14 days with measurements performed at each interval after drying. The solutions were renewed at each interval. Signifiest of the products in relationship to enamel and dentin.The comparison between bulk and nano ZnO particles were antecedently studied but describing the dose-dependent toxicity and the ameliorative effect of vitamins (E and C) in Oreochromis niloticus, have not been previously documented. Therefore, the present study was designed to investigate the ameliorative effect of vitamins (E and C) against oxidative stress and biochemical alterations induced by sublethal concentrations of zinc oxide bulk particles (ZnOBPs) and zinc oxide nanoparticles (ZnONPs). Toxicity tests were carried out on O. niloticus and showed that 96 h LC50 values of ZnOBPs and ZnONPs were 84 mg/l and 5.6 mg/l respectively. Exposure of the studied fish to these s
