Both composite resins and glass ionomer cements are technique-sensitive, and ideally need to be placed under rubber dam. Therefore these types of restorations are recommended for small single surfaces only. Glass ionomer cements can be used as semi-permanent restorations in primary molars when the teeth are close to exfoliation. Alternatively, glass ionomer cements may be used as a temporary measure for a few months until a permanent restoration can be placed.

Different approaches have been tried to develop restorative materials with enhanced antimicrobial properties. Glass ionomer cements (GICs) are one of those dental materials that have been investigated to improve their defending characteristics. Inhibition of microbial growth around these materials, both in-vivo and in-vitro, was thought to be due to their capabilities of release of fluoride ions [87]. However, there are different points of view about the effect of fluoride on secondary caries. Despite the presence of some research that has demonstrated that this problem was reduced with fluoride-containing restorations [88,89], others could not prove the inhibiting effect of fluoride after setting. Moreover, other investigations [90,91] concluded that no relation between fluoride release and microbial inhibition was evident and microbial cells may affect the dentin/restoration interface by microleakage causing secondary caries. The improvement of GICs is very valuable both for dental patients and dental clinicians. Therefore, our study proposes a new strategy for preventing dental caries by using CS-MC-GIC. The present study demonstrated that the CS-MC-GICs groups had high anticandidal activities against PDR-CA-SYN-01. The potential antimicrobial action of CS-MC-GIC may be due to the structure of this modified derivative as it has different hydrophilic functional groups, such as hydroxyl, amino, and carboxyl groups. Similarly, in our previous study methyl acrylate chitosan bearing p-nitrobenzaldehyde exhibited antibacterial activity due to the hydrogen bond deformation and a substitution of the p - nitrobenzaldehyde on the nitrogen atoms [48].
A comparative evaluation of microleakage and dentin shear bond strength of three restorative materials

Glass ionomer cement (GIC) has been successfully used as dental restorative material following its invention by Wilson and Kent in the early 1970s [5]. The unique properties of GIC's are their adhesion to moist tooth surfaces, anti-cariogenic character, lack of exothermic polymerization, excellent adhesion to dentin, and satisfactory biocompatibility [6]. One of the major drawbacks of GICs is their weak mechanical properties like brittleness, low strength, and toughness [5,6]. Because of their poor mechanical strength, GICs were mainly used to restore anterior teeth and in areas with minimal load [6].

In the last decades, conventional and modified glass ionomer cements have been frequently used in dentistry because they show advantages compared to other dental materials, such as chemical adhesion and fluoride release. However, information on the genotoxic potential of these materials is scarce in the literature (Ribeiro et al. 2006; Bakopoulou et al. 2009). Since the glass ionomer cements has some metals in its composition that stay in contact with the oral tissues for long periods, they can cause a biological risk (Ribeiro et al. 2006a, b; Gavić et al. 2019).
