Evaluation of surface roughness and color changes of restorative materials used with different polishing procedures in pediatric dentistry

Abstract

This study aimed to evaluate the color stability and surface roughness properties of four different restorative materials used in pediatric dentistry clinics as a result of four different polishing procedures. A total of 128 samples, 32 of each restorative material, were prepared by placing them in polyethylene molds with a diameter of 6 mm and a height of 2 mm, in accordance with the instructions of the manufacturers, to be polished with four different polishing procedures (n = 8). After finishing and polishing, the samples were kept in distilled water at 37 ◦C for 24 hours. Surface roughness and color stability measurements of the samples were then made. The Hysitron TI 950 TriboIndenter device in Mustafa Kemal University’s Technology Research & Development Center was used for surface roughness test measurements, and the Ra parameter was taken as a basis. A spectrophotometer instrument (VITA Easyshade® Advance 4.0 (VITA Zahnfabrik, Bad Sackingen, Germany)) was used to determine color stability and color differences were recorded according to the CIEDE 2000 system. The lowest roughness values were observed in G-aenial restorative material polished with Super-Snap material, and the highest roughness values were observed in Equia material polished with Identoflex material. When all materials were evaluated, the smallest color change values were seen in G-aenial material polished with Super-Snap, and the most color change values were detected in Equia material polished with Identoflex. It was observed that the relationship between surface roughness and color change was statistically significant. The lowest color change and surface roughness values were observed in the G-aenial material polished with Super-Snap. For improved clinical results, the most appropriate polishing procedure should be chosen based on the restorative material used.

Properties of Nanohybrid Dental Composites—A Comparative In Vitro Study

“…The physical properties of materials also change over time. Additionally, other variables can have a significant influence on composite behavior, such as cure depth [46] and fiber incorporation [47]. Also, these variables should be included in future studies.…”

Effect of the Different Dietary Supplements on the Average Surface Roughness and Color Stability of Direct Restorative Materials Used in Pediatric Dentistry

“…The ingredients used in drug formulations in the form of syrup/liquid include sugars, acids, buffering agents, and coloring agents in the form of oil and/or water-soluble agents. In addition, the long-term use of these drugs may cause adverse effects such as erosion, internal/external staining on tooth surfaces, and surface degradation of dental restorations due to their endogenous pH and high titratable acidity [ 1 , 20 , 22 , 23 ]. The surface roughness and color stability in restorative materials used in pediatric dentistry are essential to increase the longevity of the restoration and to maintain children’s oral health.…”
