“…In addition, the highest values of FS and DTS presented by Fuji II LC have been previously attributed to a better integrated interface between the glass particle and polymer matrix [ 4 ] and present 76.2 wt% [ 57 ]. The standard deviations of the samples submitted to the DTS test were similar to previous studies [ 60 , 65 , 66 ].…”

This study is aimed at evaluating the flexural strength (FS), fracture toughness (FT), and diametral tensile strength (DTS) of three resin-modified glass-ionomer cements (RMGICs): Ketac Nano, Riva Light Cure, and Fuji II LC. One hundred twenty specimens were prepared from the RMGIC materials ( n = 10 ). The cements were mixed and inserted into different mould sizes according to the test performed: FS: rectangular Teflon mould ( 32 mm × 3.15 mm × 2 mm ); FT: notchless triangular prism (NTP) Teflon mould ( 6 mm × 6 mm × 6 mm × 12 mm ); and DTS: ring road stainless steel mould ( 6 mm × 3 mm ). Specimens were light cured for 20 seconds on each surface and stored in distilled water at 37 ° C ± 2 ° C for seven days prior to tests. To evaluate the influence of storage in the mechanical properties of the RMGIs, specimens tested for DTS were stored in distilled water at 37 ° C ± 2 ° C for 32 days prior to test. Data were analyzed by ANOVA and Tukey’s test ( α = 0.05 ). Fuji II LC presented significantly higher values for all tests employed when compared to Ketac Nano and Riva LC RMGIs. There was no significant difference on DTS before and after the 32-day storage for each material. Fuji II LC presented superior mechanical properties when compared to Ketac Nano, and Riva LC storage showed no influence on the mechanical properties of the RMGI materials tested.

“…Bilić-Prcić et al, 16 have reported that cuttlefish bone HA reduced the CS of GICs. However, Mederos et al, 17 reported improvement in mechanical properties. Previous research by Moshaverinia et al 2 demonstrated a 12% increase in compressive and DTS at 5% concentration compared to traditional GIC.…”

ORIGINAL RESEARCHmodality is the use of additives such as silver amalgam, photo polymeric resin, silicone whiskers, and hydroxyapatite (HA) nanoparticles. 3 IntroductIonGlass ionomer cement (GIC) has several advantages over other cement. Their primary advantage is the ability to chemically bond to enamel and dentin. Other advantages are ease of handling, anticariogenic property as a result of fluoride release, improved biocompatibility, and thermal expansion coefficient since it is comparable to natural dentition. 1 In addition to these advantages GIC has several disadvantages. It is highly sensitive to moisture, lacks sufficient strength, and is wear resistance to be used as a posterior restorative material. Therefore, improvements are constantly being made to bring about an enhancement in the physical properties of the cement, considering its other advantages. 2 The said deficiency in mechanical properties of GIC limits its use to low-stress bearing areas. Major requirements of mechanical properties for cement to be used in the posterior dental region are with regard to CS and diametral tensile strength. Therefore, these have been used as predictors of clinical performance. 3 Among the various methods used to improve the mechanical characteristics of traditional GIC, by far the most predominant 1,
