Investigation of colour and surface changes of ceramic CAD/CAM blocks with different surface treatments after immersion to different beverages

Surface treatment, liquid, and aging effects on color and surface properties of monolithic ceramics

“…The effects of materials and surface treatments; 22 surface treatments; 23 24 surface treatments and liquids; 25 26 and types of liquids 27 on the surface roughness of the monolithic ceramics were examined. Vichi et al 22 reported that the type of ceramic (ZLS and LDS) and surface treatment [polish (30 and 60 s) and glaze (paste and spray)] significantly affected the surface roughness.…”

“…Although Brescansin et al 23 did not find a significant difference between the roughness of polished and glazed LDS samples, Brodine et al 24 reported that glazed samples of LDS exhibited lower roughness values than polished samples of LDS. Kiliç Avşar et al 26 reported that the roughness values of ZLS were not affected by the surface treatment type (glaze and polish) and liquid type (coffee and wine), whereas Alencar-Silva et al 25 reported that the LDS roughness values were not affected by the liquid type (distilled water, coffee, tea, wine, and cola), but were significantly affected by the surface treatment type (polish and glaze). Alsilani et al 27 reported that storage in different liquids (coffee, cola) did not change the roughness of LDS.…”

“…Numerous studies investigated the effects of materials; 18 materials and aging; 19 materials, surface treatments, liquids, and aging; 20 and surface treatments, liquids, and aging 21 on the optical properties of monolithic ceramics. On the other hand, the effects of materials and surface treatments; 22 surface treatments; 23 24 surface treatments and liquids; 25 26 types of liquids; 27 and storing in liquid 28 on the surface properties (gloss and roughness) of monolithic ceramics were investigated.…”

“…People consume different types of beverages. 20 21 25 26 27 28 Studies reported 20 25 26 27 that acidic beverages could affect the surface of CAD-CAM monolithic ceramics and change the structure of these materials over time.…”
