Abstract

Glass ionomer cements (GICs) are being used for a wide range of applications in dentistry. In order to overcome the poor mechanical properties of glass ionomers, several modifications have been introduced to the conventional GICs. Nanotechnology involves the use of systems, modifications or materials the size of which is in the range of 1–100 nm. Nano-modification of conventional GICs and resin modified GICs (RMGICs) can be achieved by incorporation of nano-sized fillers to RMGICs, reducing the size of the glass particles, and introducing nano-sized bioceramics to the glass powder. Studies suggest that the commercially available nano-filled RMGIC does not hold any significant advantage over conventional RMGICs as far as the mechanical and bonding properties are concerned. Conversely, incorporation of nano-sized apatite crystals not only increases the mechanical properties of conventional GICs, but also can enhance fluoride release and bioactivity. By increasing the crystallinity of the set matrix, apatites can make the set cement chemically more stable, insoluble, and improve the bond strength with tooth structure. Increased fluoride release can also reduce and arrest secondary caries. However, due to a lack of long-term clinical studies, the use of nano-modified glass ionomers is still limited in daily clinical dentistry. In addition to the in vitro and in vivo studies, more randomized clinical trials are required to justify the use of these promising materials. The aim of this paper is to review the modification performed in GIC-based materials to improve their physicochemical properties.

  • The reduced mechanical strength and wear resistance of GIC limit its application in high-stress regions like molars.

    “Nonetheless, the reduced mechanical strength and wear resistance of GIC limit its application in high-stress regions like molars.”

    From Minimally Invasive Techniques for Managing Dental Caries in Children: Efficacy, Applications, and Future Directions (2025) · cites this paper as [62]

    The Introduction says GICs are brittle, have poor wear resistance and poor mechanical properties, and that these drawbacks restrict their clinical use. It does not specifically identify molars or high-stress regions as restricted applications. (LLM, conf=0.82)

  • Bioactive materials enhance aesthetics, especially in pediatric dentistry, where modified resin-based bioactive materials offer a more visually appealing alternative to conventional glass ionomer cement.

    “Furthermore, these materials play a significant role in enhancing aesthetics, especially in the field of pediatric dentistry, where modified resin-based bioactive materials offer a more visually appealing alternative to conventional glass ionomer cement [62].”

    From Minimally Invasive Techniques for Managing Dental Caries in Children: Efficacy, Applications, and Future Directions (2025) · cites this paper as [62]

    Section 3.3 reports that nanoparticles improve the aesthetic properties of dental resin composites and that smaller GIC fillers make restorations smoother and easier to polish. The Introduction also identifies deciduous-tooth restoration as a use of GICs. Neither passage establishes that modified resin-based bioactive materials are a more visually appealing alternative to conventional GIC specifically in pediatric dentistry. (LLM, conf=0.83)

    Experimental — accuracy not yet measured
  • The increased expense of bioactive materials compared to conventional options limits their availability, especially in low-resource environments where cost-effectiveness is a significant issue.

    “The increased expense of bioactive materials in comparison to conventional options limits their availability, especially in low-resource environments where cost-effectiveness is a significant issue [62].”

    From Minimally Invasive Techniques for Managing Dental Caries in Children: Efficacy, Applications, and Future Directions (2025) · cites this paper as [62]

    The Introduction discusses the bioactive properties of glass ionomer cements, but does not address their price or availability. Searches for cost, expense, cost-effectiveness, and low-resource settings found no passage in our copy supporting the claimed comparison or access limitation. (LLM, conf=0.70)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
