Abstract

This study was designed to determine the effect of different RESTORATIVE MATERIALS on FRACTURE RESISTANCE of lower anterior teeth with CLASS V cavities. One hundred and ninety non - carious with restored permanent mandibular incisors were selected and divided into nineteen groups with 10 samples, from each cavities. Only half of the samples were load cycled by three brands at 3HZ frequency for 250000 cyclesin artificial mouth unit. The samples tested by applying shear force with cross head speed of 5mm/min in instron . Loading did not have any significant bond strength . In all samples, 4mm width of cavity had less bond strength than 2, 3 mm widths. Also, in the compoglass and glassionomer L.C. groups, cavities with 2 had more strength than cavities with 4mm width. In the case of tetric flow restorative material, there wasn't significant difference among different widths of cavity. In 4 cavity widths, tetric flow had the highest shear bond strength. Although the results showed that all the restorations need an average load more than masticatory forces in the mouth to fail, but tetric flow composite with combination of chemical adhesion properties and optimum elastic characteristics widths. The intention point shows that long term success can be achieved by using tetric flow restorative material.
