“…Several scholars have tried to incorporate silica (SiO 2 ) in GIC matrix, aiming to improve their properties. 30 31 32 33 34 Shiekh et al synthesized a nano-hydroxyapatite-silica (nano-HA-SiO 2 ) powder using one pot, sol-gel technique. 32 The authors evaluated the Vickers microhardness of nano-HA-SiO 2 -GIC having different formulations by wt % of SiO 2 (11, 21, and 35%).…”

The aim of this article is to provide a brief insight regarding the recent studies and their recommendations related to the modifications to glass ionomer cement (GIC) powder in order to improve their properties. An electronic search of publications was made from the year 2000 to 2018. The databases included in the current study were EBSCOhost, PubMed, and ScienceDirect. The inclusion criteria for the current study include publication with abstract or full-text articles, original research, reviews or systematic reviews, in vitro, and in vivo studies that were written in English language. Among these only articles published in peer-reviewed journals were included. Articles published in other languages, with no available abstract and related to other nondentistry fields, were excluded. A detailed review of the recent materials used as a filler phase in GIC powder has revealed that not all modifications produce beneficial results. Recent work has demonstrated that modification of GIC powder with nano-particles has many beneficial effects on the properties of the material. This is due to the increase in surface area and surface energy, along with better particle distribution of the nano-particle. Therefore, more focus should be given on nano-particle having greater chemical affinity for GIC matrix as well as the tooth structure that will enhance the physicochemical properties of GIC.

“…Sorption and solubility assays detected similar results for GIC-THEO and GIC-C. However, other studies detected higher water sorption and greater microleakage when other substances such as 1% natural propolis, 2% lyophilized propolis (Troca et al 2011 ), or 0.06, 0.08 and 0.1% per weight of silica particles (Felemban and Ebrahim 2016 ) were utilized in modified GICs. In these studies, (Troca et al 2011 ; Felemban and Ebrahim 2016 ), compressive and tensile strengths were preserved.…”

Effects of theobromine addition on chemical and mechanical properties of a conventional glass ionomer cement

et al. 2019

In vitro effect of 1% theobromine addition on the physical and chemical properties of conventional glass ionomer (GIC) cement was investigated. Conventional GIC (GIC-C) and 1% theobromine added to GIC (GIC-THEO) specimens were compared regarding the microhardness (n = 10), sorption (n = 5), solubility (n = 5), color change (n = 10), fluoride release in saliva (n = 10) and the amount of biofilm deposition (n = 20). Compared against conventional GIC, adding 1% theobromine increased microhardness (p < 0.05), while its sorption, solubility, color and fluoride release to saliva (p > 0.05) remained unchanged. On the other hand, Streptococcus mutans biofilm amount deposited on its surface decreased statistically when theobromine was added to GIC (p < 0.05). Based on the results, it could be concluded that 1% theobromine addition to GIC can be a good strategy as it keeps some of its properties and improves microhardness and biofilm deposits strengthening its role in the preventive approach of dentistry.

“…In previous studies, the compression strength of RMGICs were found to be between 67.61 and 218.46 MPa. [10][11][12][13] According to ISO (International Standards Organization) standards, the materials are considered to be reliable if they have a compressive strength above 130 MPa.…”
