Abstract
In this study, compressive strengths of three condensable composite resins(ALERT, SureFil. Solitaire), conventional hybrid composite resin(Z-100) and amalgam(HI-Aristaloy 21) according to the 6 types of cavity design(cylinder, trapezoidal, butt-joint, round bevel, long bevel and short bevel) were measured and appearance of fracture surfaces were observed with SEM, thus evaluated clinical applications of condensable composite resins according to the cavity designs.
The results were as follows:
1.Compressive strengths according to experimental materials were the highest in SureFil, and Z-100, ALERT, Solitaire, Hl-Aristaloy 21 in order.
2.SureFil showed the highest compressive strength(p〈0.05) , compressive strengths of ALERT and Solitaire were lower than that of Z-100, hybrid composite(p〈0.05) .
3.Compressive strengths according to specimen design were the highest in trapezoidal shape(p〈0.05) and no significant difffrence was detected between other specimen designs.
4.The appearance of condensable composite resin under SEM was of a diverse configuration according to component of resin matrix, shapes of filler and surface treatments between resin and filler.
