“…In order to deal with such an issue, powdery CNFs have been introduced. Nishimura et al [ 202 ] incorporated the water-free powdery CNFs into a conventional GIC and evaluated the effect of the CNFs addition on the mechanical strength and fluoride-ion release of the resultant composite. The modified GIC showed better compressive, flexural and diametral tensile strengths as compared to the unmodified GIC ( Table 3 ).…”

Overall perspective of nanotechnology and reinforcement of dental biomaterials by nanoparticles has been reported in the literature. However, the literature regarding the reinforcement of dental biomaterials after incorporating various nanostructures is sparse. The present review addresses current developments of glass ionomer cements (GICs) after incorporating various metallic, polymeric, inorganic and carbon-based nanostructures. In addition, types, applications, and implications of various nanostructures incorporated in GICs are discussed. Most of the attempts by researchers are based on the laboratory-based studies; hence, it warrants long-term clinical trials to aid the development of suitable materials for the load bearing posterior dentition. Nevertheless, a few meaningful conclusions are drawn from this substantial piece of work; they are as follows: (1) most of the nanostructures are likely to enhance the mechanical strength of GICs; (2) certain nanostructures improve the antibacterial activity of GICs against the cariogenic bacteria; (3) clinical translation of these promising outcomes are completely missing, and (4) the nanostructured modified GICs could perform better than their conventional counterparts in the load bearing posterior dentition.

“…Microcrystalline Cellulose microfibers (MMC) or CNCs have been utilized to improve the mechanical and chemical qualities of a variety of dental composites [ 32 , 33 ]. In this study, the miswak fibers containing a major component of cellulose were incorporated in a resin-based pit and fissure sealants to improve mechanical properties like flexural strength, compressive strength, and Vickers hardness.…”

The occlusal surface of a tooth is affected by the development of biofilm in pits and fissures as bacteria and food particles accumulate in its complex structure. In this study, miswak fibers containing cellulose and antimicrobial extract were incorporated in commercial pit and fissure sealants. The miswak powder was characterized by different analytical techniques. The powder was mixed in different ratios (0–5%) into a pit and fissure sealant to result in five sealants (Groups 0–5), and their mechanical properties i.e. flexural strength, compressive strength, and Vickers hardness were evaluated. The sealants were also evaluated against streptococcus mutans oral pathogenic bacteria. SEM analysis confirmed irregular shape and micron-size particles of miswak powder. The infrared spectral analysis and X-ray differential peaks showed characteristic peaks related to miswak fibers. The particle appearance increased in prepared pits and fissure sealants with higher loading of miswak powder in SEM analysis. The flexural strength, compressive strength, and Vickers hardness values were obtained in the range of 148–221 (±16.6: p -value < 0.001) MPa, 43.1–50.3 MPa (±1.7: p- value <0.001), and 15.2–21.26 VHN (±0.56: p -value <0.001) for control and prepared sealant specimens respectively. In the antibacterial study, the zone of inhibitions increased with increased content of miswak from 15.6 ± 0.45 mm (Group 1) to 20.3 ± 0.32 mm (Group 5). The MIC was calculated to be 0.039%. The prepared experimental sealant had acceptable mechanical and good antibacterial properties therefore it could be recommended as an efficient pit and fissure sealant.

“…Much effort for improving conventional GIC has been reported since its invention by Wilson and Kent in 1968. For example, resinmodified GIC (RMGIC), [10][11][12] metal-modified GIC (MMGIC), 13 fiber-reinforced GIC (FRGIC), 14 giomers, 15 hainomers, 16 amalgomers, 17 zirconium-modified GIC, 18 nanofiber-reinforced GIC, 19 etc.…”
