“…Table 1 shows an increase in mass at times of 30 and 60 days for the Control group, 15 to 60 days for the NPHAp group, and 15 days for the BAG group, possibly due to fluoride recharging by the GIC, when in contact with the toothpaste during the brushing test. Panigrahi et al [39] and Yli-Urpo et al [21] observed that after the association of a GIC with the remineralizing material there was a higher release of fluoride, and consequently a higher incorporation of these ions.…”

This study evaluated the physical and mechanical properties of glass ionomer cement (GIC) associated with 5% hydroxyapatite nanoparticles (NPHAps) and 10% bioactive glass (BAG) 45S5 before and after brushing at different storage times. Surface roughness was evaluated using a rugosimeter, Vickers hardness using a microdurometer, and mass variation measured in an analytical balance at 1, 7, 15, 30, and 60 days before and after the brushing test, with the aid of toothbrushing simulator and soft bristle toothbrushes. Nonnormal distribution was observed, and the nonparametric Wilcoxon and Kruskal–Wallis tests followed by Dunn’s were performed, with a significance level of 5%. We observed higher values for mass loss on the first day for all groups. The surface roughness was lower in the control and NP groups, 30 days after brushing. Higher values for hardness were found in the control group and lower ones for NP, after brushing. The control and BAG groups presented a decrease in hardness over time. The NP group presented the highest values before brushing, while the control group had the highest values after brushing. The association of NPHPa with the GIC is the most promising combination, since it presented satisfactory values for surface hardness. However, conventional GIC not associated with NPHPa or BAG is still an option, since it is available in the market and the most economically viable option.

“…HAp has been used widely in dentistry as they possess some advantages including biocompatibility, hardness similar to that of natural tooth and intrinsic radiopaque response . Addition of HAp to conventional GICs was investigated by some researchers in the attempts to enhance its mechanical properties . Nicholson et al first reported the incorporation of HAp into GICs in the scientific literature .…”

“…Moreover, it has the ability to enhance the bond strength to tooth structure because of its similar composition and structure to enamel and dentin. Recently, Panigrahi et al further investigated the fluoride release from HAp incorporated GICs following recharging with low fluoride dentifrices. The result showed that fluoride rechargeability and re‐release remains unaffected by the addition of HAp whiskers.…”

Objective The aim of this review was to provide an insight about the factors affecting the properties of glass ionomer cements and provides a review regarding studies that are related to modification of glass ionomer cements to improve their properties, particularly on physical‐mechanical and antimicrobial activity. Methods PubMed and Science Direct were searched for papers published between the years 1974 and 2018. The search was restricted to articles written in English related to modification of glass ionomer cements. Only articles published in peer‐reviewed journals were included. The search included literature reviews, in vitro, and in vivo studies. Articles written in other languages, without available abstracts and those related to other field were excluded. About 198 peer‐review articles in the English language were reviewed. Conclusion Based on the finding, most of the modification has improved physical‐mechanical properties of glass ionomer cements. Recently, researchers have attempted to improve their antimicrobial properties. However, the attempts were reported to compromise the physical‐mechanical properties of modified glass ionomer cements. Clinical significance As the modification of glass ionomer cement with different material improved the physical‐mechanical and antimicrobial properties, it could be used as restorative material for wider application in dentistry.

ObjectiveThis study aims to compare the clinical and radiographic efficacy of Equia system bulk fill glass hybrid material with composite resins in the permanent restoration of pediatric patients' permanent teeth.Materials and MethodsThe study included 44 pediatric patients aged 8–16 who applied to Necmettin Erbakan University Pediatric Dentistry Department. The groups were formed as symmetrical teeth in the same patient using the split‐mouth design. The study included class I caries lesions of 144 permanent teeth. Group 1 was restored with the Equia system bulk fill glass hybrid material (Equia Forte HT + Equia Forte Coat [GC, Co, Tokyo, Japan]) (n = 72) and Group 2 with the Charisma Smart universal composite resin (Kulzer, Gmbh, Hanau, Germany) + Clearfil SE Bond (Kuraray, Noritake, Sakazu, Okayama) (n = 72). Evaluations were performed clinically and radiographically by two physicians in 2nd week, 3rd month, 6th month, and 12th month and the results were recorded. Clinical evaluation was carried out using modified‐USPHS criteria. Obtained data were statistically analyzed using Kendall's W test and Cochran's Q test for the comparison within the group, and the Chi‐square test for the comparison between groups.ResultsAmong the materials utilized in the study, there was no statistically significant difference in marginal adaptation, marginal discoloration, retention, anatomical form, postoperative sensitivity, and secondary caries according (p > 0.05). Group 2 outperformed statistically significant Group 1 in terms of color match in all periods (p < 0.05). While there was no statistically significant difference in surface structure between the groups in 2nd week and 3rd month (p > 0.05), there was a statistically substantial difference in 6th, and 12th months (p < 0.05). No secondary caries or periapical lesions were found in any restorations during radiographic evaluation.ConclusionAfter a year, the clinical performance of both Equia and composite resins was equivalent and successful in the majority of the measures against which they were evaluated.Clinical SignificanceBased on the results of the research, Equia system bulk fill glass hybrid restorations are considered a viable alternative to composite resins in class I permanent teeth restorations.
