Abstract:

Introduction and Purpose: The purpose of this study is to evaluate the impact of different adhesive simans on microsisection on proximal surfaces in Class II indirect composite resin restorations. Method and Requirements: In this study, 24 untouched third molar teeth were included. Standard Class II cords are prepared so that they will be on both distal and mesial surfaces of the teeth and above the mine-sement combination. The study groups were divided into 4 siman groups: GCem LinkAce (GCm) (GC, Japan), Panavia F 2.0 (P) (Kuraray, Japan), RelyX U200 (Rx) (3M ESPE, USA), Superbond C&B (SB) (SunMedical, Japan) and Control (V) (Variolink II, Ivoclar Vivadent, Schaan, Liechtenstein). For each tooth, the messian cavity will be a working group and the distal cavity will be a control group. Restorations were obtained from indirect composite material (Gradia; GC, Japan) and attached to the caves. The samples were applied thermosic (5-55Co,5000 cycles) and then the samples were kept in a 50% silver nitrate solution for 24 hours. It was cut from the teeth as a mesio-distal and the microscopic amounts were assessed by the digital imaging method (24x; Leica optical microscope, Germany). The order scale used: 0-4 (0 = no micro leak and 4 = the penetration of paint along the axile wall). The average values for each group were recorded and these values were statistically analyzed using the Wilcoxon Signed Ranks test. (alpha=0,05) RESUMES: There is no significant difference between the oclusal microsisity values of all groups (GCm: 0; P: 0.17 ±.0.4; Rx: 0 and SB: 0.17 ±. It is 0.4 (P> 0.05 ) The minimum microsisance values (μm ± SD) were recorded for GCm and Rx self-adjective simans for oklusal (0.00; 0,00) and gingival (0,83 ± 0,4; 0,50 ± 0,5), respectively. The highest microsisance was recorded in gingival parts with SB and P (2,0 ± 1,4; 1,5 ± 0,84) and the difference is significant compared to other groups. (P is 0.05 ) CONTRIBUTION AND RESULTS: Tested self-adjustable dual-cury resin simens showed long-term microsisance stability, while self-cury resin simens showed the highest microsisance values.
