“…In addition to hydrochloric acid, gastric acid contains different enzymes, such as pepsin with proteolytic properties that can degrade the collagen [ 24 ]. The results of studies regarding the aggravating effect of pepsin on dentin erosion are controversial [ 25 , 26 ]. A previous study showed significantly higher amounts of pepsin, trypsin and amylase in the saliva of patients with chemical erosion caused by endogenous acids, compared with normal individuals [ 26 ].…”

Objective: This study aimed to assess the effect of fluoride varnish on glass ionomer microhardness changes after endogenous acid erosion challenge. Methodology: In this study, 40 conventional glass ionomer (CGI; Fuji IX) and 40 resin-modified glass ionomer (RMGI; Fuji IILC) discs were fabricated and divided into 4 subgroups (n ¼ 10) for immersion in synthetic gastric acid or saliva for 27 h with/without fluoride varnish application. The surface microhardness was measured at baseline and after immersion, and the change in microhardness was calculated. Data were analyzed using analysis of variance and T-test. Results: A reduction in microhardness was noted in all subgroups following immersion. The lowest change in microhardness of both CGI and RMGI occurred in artificial saliva. In CGI groups, the highest reduction in microhardness occurred in synthetic gastric acid with fluoride varnish application, and the reduction was significantly different from that of the CGI group with fluoride varnish application (p value ¼ .01). In RMGI groups, the highest reduction in microhardness was noted in synthetic gastric acid without fluoride varnish application, and the reduction was significantly different from that of the other groups (p value < .05). Conclusions: Exposure to synthetic gastric acid caused a significant reduction in microhardness of RMGI. Varnish application significantly decreased the acid susceptibility of RMGI, but not that of CGI.

“…13,[24][25][26] Since GICs are inorganic materials, they are susceptible to acid erosion, but with decreased susceptibility for RMGICs. [27][28][29][30] Several factors, involving frequent acidic foofstuffs exposure are responsible for the development of dental erosion. [31][32][33] The high prevalence of dental erosions is principally associated with the widespread consumption of acidic beverages, specially coke.…”

“…34 Several studies have been conducted to evaluate the erosive effects of different factors on the surface topography, chemical composition and behavior of direct and indirect restorative materials. [27][28][29][30][31][34][35][36][37][38] Several studies were conducted to evaluate the role of pH cycles on the validity of bond strength of resin composite restorations [39][40][41] , bond strength of restorations to eroded enamel and dentin 42,43 , but no or little information are available about the effect of pH cycling on the bonding of RMGICs to dentin. 44 From the previous information a study designed to evaluate the role of an erosive beverage, Coca cola, on the micro-shear bond strength of nano-fill resin modified glass-ionomer cement to dentin, after different conditioning protocol, may be of interest.…”

Objective: This study was designed to evaluate the role of an erosive beverage, Coca cola, on the microshear bond strength of a nano-fill resin modified glass-ionomer cement to dentin, after different conditioning protocols, no conditioning, GC conditioner and KN primer. Materials and Methods: The occlusal enamel of forty two third molar teeth was removed, exposing the coronal dentin. Thirty prepared teeth were randomly divided into three main groups (n=10). Group 1, flat dentin surface was left unconditioned (control). Group 2, GC cavity conditioner was applied. Group 3, Ketac Nano Primer was applied. Three pieces were cut from a polyethylene micro-bore tygon tube, for each specimen. KN resin modified glass ionomer cement was applied. Each group was further distributed into two subgroups (n=5). Subgroup i, teeth were immersed in artificial saliva (control). Subgroup ii, teeth were subjected to Coca Cola pH cycles. Each specimen was stressed in shear using a load cell of 5 KN at a crosshead speed of 0.5 mm/min. The remaining 12 teeth were divided according to the previously mentioned grouping system, and observed using SEM. Results: The data collected for µSBS were subjected to two-way ANOVA test, followed by Tukey's post hoc test. Considering the dentin conditioning factor, with storage in artificial saliva; the control group revealed the least µSBS values, followed by the group conditioned with KNP and GC conditioning, respectively. Control group posses a significant decrease in the µSBS compared to either GC or KNP groups. With Coke pH cycling; the control group revealed the least µSBS values, followed by KNP and GC conditioning, respectively. All the tested groups are significantly different from each other Considering the erosive pH cycling factor, all the teeth revealed significant decrease in the µSBS values, when exposed to erosive Coke pH cycling. Most failure modes are adhesive, followed by mixed failures. The SEM examination showed a filler-free zone in the conditioned groups, with the greatest thickness with KNP. Cylindrical shaped resin tags, were observed when dentin is conditioned with KNP, whereas budding configuration is formed with GC conditioner. Smear layer has been completely removed with GC conditioner. Dentin conditioning (1432)

“…Erosion and dental abrasion represent some variables directly linked to the increase in surface modifications of dental materials. Exposure to acids found in commercially available beverages and food, associated with mechanical efforts during tooth brushing, can cause an increase in surface roughness ( 8 , 9 , 10 , 11 , 12 , 13 ).…”

Background The present in vitro study aimed to evaluate and compare the surface roughness of a colored compomer and a composite resin, after 15 days of erosive-abrasive cycling. Material and Methods The sample included ninety circular specimens, randomly divided (n = 10): G1 Berry, G2 Gold, G3 Pink, G4 Lemon, G5 Blue, G6 Silver, G7 Orange and G8 Green, referring to the different colors of compomer (Twinky Star®, VOCO, Germany) and G9 for composite resin (Z250®, 3M ESPE). The specimens were submerged in artificial saliva and stored at 37°C for 24 hours. After polishing and finishing, the specimens were submitted to initial roughness (R1). Then, the specimens were submerged in an acidic cola-based drink for 1 minute and then exposed to electric toothbrushing for 2 minutes for 15 days. After this period, the final roughness (R2) and the ΔRa were performed. Data were submitted to ANOVA and Tukey’s test for intergroup comparison and paired T-test for intragroup comparison ( p <0.05). Results Among compomers, the green color presented the higher/lower initial and final roughness values (0.94 ± 0.44, 1.35 ± 0.55) with lemon color presenting the most prominent real roughness increase (ΔRa = 0,74) whereas composite resin showed the lower values (0,17 ± 0.06, 0,31 ± 0.15; ΔRa = 0,14). Conclusions All compomers, after the erosive-abrasive challenge, presented an increase in roughness values when compared to composite resin with a highlight to green tones. Key words: Compomers, composite resins, surface properties.
