Sealing capacity of a photochromatic flowable composite as protective base in nonvital dental bleaching.

2006

Aim  To evaluate microleakage of a flowable composite used as a protective isolating base, applied with different adhesive systems. Methodology  Seventy root-filled teeth were divided into seven groups. A flowable composite base (Tetric Flow Chroma) was used with three adhesive techniques (Syntac, Excite, Excite DCS; in the three cases with and without acid etching) and in a control group without dentine conditioning or adhesive placement. A 30% hydrogen peroxide solution was applied for 24 h in the pulp chambers, followed by the placement of a dye (silver nitrate) for 4 h. Each tooth was sectioned longitudinally, and examined under 4× magnification to assess the tooth/restoration dye leaka…
