Summary

Evaluation of Resin Composite Posterior Restorations Using Modeling Resin Insertion Technique versus Conventional Composite Placement Technique in Class I Lesions: Randomized Clinical Trial

Conditions

  • Class I Composite Restorations

Interventions

PROCEDURE

Modeling Resin Insertion Technique

One drop of modeling resin will be dispensed into a clean mixing well. Following the placement of the resin composite into the prepared site, a composite instrument (round-ended plugger with a diameter of 2 mm) will be dipped into the modeling resin. With modeling resin on the instrument, the resin composite is sculpted and manipulated to the desired shape. This will be repeated with each increment. Each increment will be polymerized for 20 sec with a LED light-curing unit.

PROCEDURE

Conventional resin composite Incremental Placement Technique

A three-step etch-and-rinse adhesive system will be used according to the manufacturer's instructions. 37.5% phosphoric acid (Kerr Co, Orange, CA, USA) will be applied to the enamel and dentin for a period of 30 s and 15 s, respectively. Subsequently the cavities will then be rinsed with an air/water spray for 15 s. A layer of primer will be applied to the dentin for 30 sec, afterward gentle air-drying for 5 sec. Then, the bond (AdheSE adhesive) will be applied on the enamel and dentin and light cured with a LED curing unit for about 30 sec. Tetric N-Ceram will then be applied using an incremental filling technique, each increment will not exceed 2mm in thickness. Each increment will be polymerized for 20 sec with a LED light-curing unit.
