Effect of contamination of bulk-fill flowable resin composite with different contaminants during packing on its surface microhardness and compressive strength: in vitro study

Table 1 Materials used in the study

	Manufacturer	Composition
Bulk-fill Flowable resin composite	Nexcomp Flow, Meta Biomed, Korea	Nanohybrid flowable composite 40 nanosized filler: Barium Aluminum borosilicate, Bis-GMA, UDMA, Bis-EMA, TMPTMA (75 weight %, 37 volume %)
Hemostatic agent	Hemo Stop solution, JK Dental Vision Company, Egypt	25% Aluminium chloride solution
Artificial saliva		Prepared by mixing of 0.4 g sodium chloride (NaCl), 1.21 g potassium chloride (KCl), 0.78 g sodium dihydrogen dehydrate (NaH₂PO₄.2H₂O), 0.005 g hydrated sodium sulfide (Na₂S.9H₂O), and 1 g urea CO(NH₂)₂ in 1000 ml deionized water. The pH of this mixture was modified with 10 N sodium hydroxide until it reached 6.7 on a pH meter [15]
Alcohol	Safwa Company, Egypt	70% Ethyl alcohol
Powdered gloves	SRI Trang Argo-Industry Public Company, LTD, Thailand	Powdered Latex examination gloves
