Surface roughness of a novel dental porcelain following different polishing procedures.
This study aimed to compare the surface roughness of a novel dental porcelain following different polishing procedures. One hundred twenty Imagine Reflex porcelain disks were prepared and randomly assigned into six groups according to different treatments: Group 1: CeraMaster polishing system (CP); Group 2: CP + diamond polishing paste (DP); Group 3: Sof-Lex polishing system (SS); Group 4: SS + DP; Group 5: SiC paper polishing; Group 6: reglazing (control). After the respective treatments, surface roughness values were measured using a profilometer. Qualitative analysis was performed using scanning electron microscopy. Results demonstrated that a combination of the CeraMaster polishing system and a diamond polishing paste could produce similar superficial smoothness to that of the reglazed surface of the tested porcelain.
