摘要: AbstractThis study evaluated the load-bearing capacity of premolars restored with three types resin composite materials in mesio-occluso-distal (MOD) cavities. Extracted human (N = 30, n = 10 per group) were randomly divided into groups; MOD cavities prepared and one following materials: Group BFC: Bulk-fill (SonicFill, Kerr Corporation), NC: Nanohybrid (Filtek Z550, 3M ESPE), SC: Silorane-based Silorane, ESPE). For NC Clearfil SE Bond (Kuraray, Japan) for SC, Silorane adhesive System Adhesive, ESPE) used. The SC groups incrementally, while those BFC bulk. After water storage (24 h, 37 °C), each tooth was subjected to compressive loading a stainless steel ball (diameter: 4 mm) perpendicular occlusal surface (1 mm/min). Failure categorized according being repairable or irrepairab...
