520			_aThe aim of the present study was to determine the effect of sonic vibration on the adaptation to cavity walls and margins and the depth of cure (assessed through microhardness testing) of sonic - fill and bulk - fill resin composite restorations after aging for 24 hours and 12 months. The materials used were sonicFill (Kerr) resin composite and X - tra fil (Voco) resin composite. A total number of 80 standardized Class II cavities were prepared on both mesial and distal wall of total number of 40 premolars. The teeth were randomly divided into two equal groups, of 20 teeth each, according to the material; either sSonicFill resin or X - tra Fil resin composite. Each group was divided into two equal subgroups, of 10 teeth each, according to sonic vibration applied; either application of resin composite using sonic vibration or without sonic vibration. Each subgroup was divided into 2 classes, of five teeth each (with 10 proximal restorations), according to the aging duration; either after 24 hours or 12 months in artificial saliva at 37{u25E6}C. In all specimens single bond universal adhesive (3M ESPE) was applied following manufacturer{u2019}s directions in selective-etch mode, followed by placement of sonicFill and X - tra Fil materials in bulk (5mm). The teeth were then sectioned into 2 halves, each half used for assessment of adaptation or depth of cure through microhardness. Each cut tooth half was then sequentially finished and polished, and ultrasonically cleaned. For adaptation assessment, the pulp chambers of each cut half were blocked, a small amount of caries detecting dye was traced over the restoration and the internal margins. The specimens were observed under digital microscope at 70X connected to computer with image analyzer software. The adaptation results were presented as gap percentage per tooth wall by calculating the axial and gingival gap length divided by the total length of the wall multiplied by 100. Surface area of voids, if present, were also calculated per specimen
