Clinical Performance of Injection-Molding Vs. Incremental Packing of Resin Composite in Cavitated Posterior Teeth

The clinical performance of 2 bonding and composite packing techniques in the proximal cavities of permanent posterior teeth will be assessed. Incremental packing with pre-curing of universal adhesive in selective etching mode is compared to injection molding of preheated composing co-cured with universal adhesive in selective-etch. Main outcomes will focus on marginal integrity, post-operative hypersensitivity, and contact form and tightness.
