Effect of silver diamine fluoride pretreatment on microleakage and shear bond strength of resin modified glass ionomer cement to primay dentin (in-vitro study)

Objectives: To evaluate in vitro, the effect of 38% silver diamine fluoride (SDF) pretreatment on microleakage and shear bond strength resin-modified glass ionomer cement to primary dentin. Materials methods: A total 80 extracted sound molars were included this in-vitro study randomly assigned into four equal groups (n=20 teeth/group) according evaluation test performed. For test, class V cavities prepared buccal surface forty teeth allocated Group I (experimental)(n=20): Primary dentin pretreated with SDFfor three minutes II (control)(n=20): treated distilled water for minutes. Class restored RMGIC, thermocycled, immersed 1% methylene blue solution 24h, sectioned longitudinally a bucco-lingual direction then examined under stereomicroscope at 40x magnification. Also SBS grouped III (experimental) (n=20): flat SDF. IV (control) water. Using Universal Testing machine determines. Failure mode was evaluated using stereomicroscope. Data collected subjected statistical analysis. Results: There no statistically significant difference between experimental control group (P=0.21). However, had significantly higher than group. (P=0.0001) Conclusion: SDF does not influence marginal seal RMGIC it raises them.
