Summary

Purpose of research: Evaluation and comparison of 24-month clinical performance of injectable and conventional resin composites in class I cavities.

Detailed description

The mechanical properties of conventional resin composites have been tried to be improved. In addition to the developed mechanical properties, the need for easy and fast application led to the development of flowable composites. Flowable composites have lower filler ratio than conventional hybrid composites so they are less rigid and have lower modulus of elasticity. For these reasons, the use of flowable composites in areas that may be exposed to high forces, especially occlusal cavities, is not recommended. Today, it is aimed to increase the wear resistance by increasing the amount of filler in flowable composites and producing injectable composites. A new product recently introduced to the market, a high-strength nano-filled injectable composite material, GC's G-ænial Universal Injectable(Tokyo,Japan), was also included in the study. This is a low-viscosity composite in which modifications have been made to provide a product with high wear resistance and depth of cure to make it suitable for posterior restorations. One lesion in each patient will be randomly assigned to be restored using either the G-aenial Universal Injectable or Filtek Z250 resin composites. The adhesive, G2-BOND Universal will be used for adhesive procedures. The clinical procedure for the restorations will be performed by a single operator. The restorations will be evaluated by two calibrated examiners at baseline and at 6, 12, 18, 24 months in accordance with the modified USPHS criteria. Data will be statistically analyzed using the Chi-square and Cochran Q tests (p \< 0.05).
