Residual excess cement was removed with a plastic hand instrument. A standard procedure of cleaning and polishing the crowns and margins was used for all samples using the following sequence: brown and green silicone rubber points (Shofu Inc., Kyoto, Japan) and Sof-Lex™ finishing and polishing discs (3M™ ESPE, St Paul, MN, USA) in a low-speed handpiece. All the samples were left undisturbed for at least 1 h and kept immersed in a water solution at a constant of 37 °C for at least 24 h before testing.
Sof lex finishing and polishing discs
Manufactured by 3M
Sourced in Japan, United States
Sof-Lex finishing and polishing discs are a line of abrasive discs designed for use in dental and clinical settings. These discs are available in various grits and are used for finishing and polishing procedures on dental restorations and surfaces.

A separating layer (MDC, California, United States) was placed into the cavities of the cast models, and the 30 indirect restorations were manufactured with UD2 color dentin composite (ENA HRi, SYNCA) employing the oblique incremental technique with layers of 2 mm thick. Each layer was photopolymerized for 20 seconds at an intensity of 1,200 mW/cm
2(Bluephase N; Ivoclar Vivadent, New York, United States). The samples were randomly distributed into two experimental groups corresponding to the cementing material (
Table 1 ): group A, 15 restorations cemented with RC (resinous cement) (Relyx U200, 3M ESPE), and group B, 15 composite restorations cemented with PR color UD2 (ENA HRi, SYNCA). All procedures were performed according to manufacturers’ instructions (
Tables 2 3 ). The restorations were polished with flexible Sof-Lex finishing and polishing discs (3M ESPE) and were subjected to a thermocycling regimen of 500 cycles with an exposure time of 30 seconds at 4°, 37°, and 57°C to simulate the environment of an oral cavity.

The samples were then submersed in a 2% methylene blue solution for 48 h, after which they were washed under a continuous stream of water for 2 min and stored for 24 h in distilled water. To evaluate the marginal sealing at dentin–material interface for both mesial and distal cavities, the teeth were sectioned in a mesio-distal direction using a Struers Secotom 50 device (Struers LLC, Cleveland, OH, USA) equipped with a 0.5 mm thick water-cooled diamond disc. At the mesial margin, the dentin-flowable composite resin interface was assessed, while at the distal margin, the interface between dentin and conventional composite was evaluated. Then, the surfaces were finished and polished using Sof-Lex finishing and polishing discs (3M ESPE, St. Paul, MN, USA).
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
