Table 1

Composition and application procedure of the materials used.

Material	Composition	Application
Vertise Flow; (Kerr, USA); Lot # 1000010715	Matrix: GPDM adhesive monomer, UDMA, BisGMA, and other methacrylate comonomers, photoinitiators; Fillers: 70% by weight. Ytterbium Fluoride, barium aluminosilicate glass, prepolymerized fillers, and colloidal silica	Brush the layer with moderate pressure for 15–20 seconds to obtain a thin layer (<0,5 mm); Light-cure for 20 seconds; Place additional increments of Vertise Flow in 2 mm or less; Light-cure for 20 seconds
Premise Flowable (Kerr, USA); Lot # 1000010505	Matrix: Bis-GMA,; ethoxylated bis-phenol-A-dimethacrylate, TEGMA, light-cure initiators, and stabilizers; Fillers: 72,5% by weight. Barium glass, prepolymerized fillers, and silica nanoparticles	Apply in increment of 2 mm or less; Light-cure for 10 seconds
OptiBond All-In-One (Kerr, USA); Lot # 3354615	Glycerol phosphate dimethacrylate (GPDM), mono- and difunctional methacrylate monomers, water, acetone, ethanol, nanofillers, and camphorquinone (CQ)	Apply one coat and scrub it using a disposable microbrush for 20 seconds; Repeat step (1); Dry with air for 5 seconds; Light-cure for 10 seconds
