| Description: | Interim Therapeutic Restoration (ITR) is frequently placed to achieve caries control especially in children. Glass ionomer cements (GIC) can ideally serve this purpose as it has advantages of chemical adhesion to dentin and enamel, as well as fluoride release and uptake into hard tissues. Therefore the aim of this study was to compare four commercially available conventional GIC based on amount of fluoride release, marginal intergrity and ability to increase microhardness of underlying artificial dentinal caries via remineralization. Standardized cavities were prepared on buccal surface of 60 extracted sound premolars and artificial caries were induced onto the dentinal floor of each cavity. Specimens were randomized into 4 groups of fifteen teeth and restored with Fuji VII®, Riva Protect, Riva Self Cure and Fuji IX GP® Extra respectively. Measurement of fluoride release was done for 60 days. Subsequently, specimens were retrieved and similar restorations were done on lingual surface for microleakage test according to standard protocols. Of each specimen, dentin underlying buccal restorations were subjected to microhardness test while lingual restorations were evaluated for marginal microleakage. One-way ANOVA test revealed significant difference in the amount of fluoride release between materials on all predetermined days of measurement (p<0.05). Cumulatively, Riva Protect released the highest amount of fluoride, followed by Fuji VII®, Riva Self Cure and Fuji IX GP® Extra. Riva Protect and Fuji IX GP® Extra showed ability to significantly improve the microhardness of artificial caries to the depth of 100 μm (p<0.05). Furthermore, there was a also significant difference in the marginal sealing ability between materials with more microleakage seen with low-viscosity materials. In conclusion, all materials are suitable as ITR. However, Riva Protect is suggested to exert the greatest cariostatic effects among the test materials.,Ijazah Sarjana Doktor Pergigian Klinikal (Pergigian Pediatrik) |
