The Effects of Mouth Rinses on the Color Stability of Resin‐Based Restorative Materials

Abstract

Patient use of mouth rinses should be subject to dental supervision to control their adverse effects on the aesthetic quality of the restoration. Knowing the composition of the restorative material is important, as is its polymerization cycle and the promotion of adequate surface texture in order to select the appropriate material for each clinical application, and to use it in an effective way to promote its best properties.

Effect of a novel commercial potassium-oxalate containing tooth-desensitizing mouthrinse on the microhardness of resin composite restorative materials with different monomer compositions

“…Resin composite materials were applied carefully into a circumferential teflon mold with the same specimen dimensions positioned onto a 0.05 mm-thick transparent polyester filmstrip (Mylar, DuPont, and Wilmington, DE, USA) over a glass slide. Materials were covered with another celluloid strip, and the glass slide weighed of 200 g for 1 minute until the slide touched the mold completely, thus allowing excess composite to flow prior to curing (21) and to minimize the oxygen inhibition and maximize the surface smoothness (16). The distance between the light and the specimen was also standardized by using this 1-mm glass slide (22).…”

“…Immersed specimes were kept in a dark glass container that was maintained in an incubator at 37°C for 12 hours, which is equivalent to a cumulative time period of 1 years of 2-minute daily use of mouthrinse (21,24). Test solutions were shaken every 3 hours to provide homogeneity (22).…”

Glass Ionomer Restorative Materials Response to Its Color Stability with Effect of Energy Beverages

“…The same procedure and measurements were carried out on each type of material at the three immersion (aging beverages), using the same equipment. This study followed the protocol described previously for dental applications and used calorimeter (Menolta) and the CIE L*a*b* coordinate system 31 . The CIE L*a*b* coordinate system is used to detect minute color variation (∆E* ab ) with sensitivity, repeatability, and objectivity.…”

“…28 Total changes in color were considered clinically satisfactory when the GI materials were immersed in distilled deionized water (control group) for 1 day, 1 week, and 1 month, on which confirms that water sorption does not alter the GI color. 28 Because of the acidity and erosive potential of energy drinks, 30,31 the GI specimen was immersed in the energy beverages for specified periods of 1 day, 1 week, and 1 month to evaluate the color change by visually as well as using specific instruments. The same procedure and measurements were carried out on each type of material at the three immersion (aging beverages), using the same equipment.…”

Giant Dielectric Constant and Mechanical, Heat Conducting and Structural Properties of Dental Composites by Adding Ca Ions

“…For this reason, oxide materials such as SiO 2 , ZrO 2 , TiO 2 , Al 2 O 3 and B 2 O 3 which can improve the mechanical strength, thermal conductivity or structural stability of the system are doped, added or substituted in the dental composites [22][23][24]. Generally, the doping of the elements or compounds in the composites are chosen to be between 5% to 30% ratio since the excess content in the main matrix causes the formation of defects which the mechanical and thermal properties exhibit worse behavior when compared by the pure materials [25][26][27][28].…”
