Abstract
The aim of the current study was to evaluate the clinical performance of two different HVGIRMs in restoring proximal cavities of permanent teeth using ART technique. A controlled clinical study was carried out. A total of 52patients of both genders were included in the study. Teeth were prepared according to ART procedures and subdivided into two subgroups where the first one was restored with ChemFil Rock HVGIRM and the other was restored using Fuij IX HVGIRM. ART instruments were used to excavate carious lesion and to prepare the cavity walls and margins. Isolation for the field was achieved using cotton rolls. Deep lesions capped with calcium hydroxide. A matrix band, matrix holder and wooden wedges were applied before restoring the proximal part. The cavity was conditioned for 15 seconds, rinsed for 20 seconds then blotted dry. High viscous glass ionomer capsules were mixed according to manufacturer instructions and inserted into the cavity. Excess material was removed and the occlusion was checked and finally the surface was coated with a layer of Vaseline.
