摘要

Aim: To investigate the adhesive bond integrity of demineralized dentin (DD) treated with Silver Diamine Fluoride (SDF) and Photodynamic therapy (PDT) (SBS) bonded to resin modified glass ionomer cement (RMGIC).Material and Methods: Sixty non-carious molars were mounted within the sections of polyvinyl pipes. Dentinal tubules were exposed, homogenized and polished. 10 samples were left untreated and categorized as group 1. Fifty samples were exposed to acetic acid for artificial demineralization and randomly allocated into 5 groups. Group 2- exposed to conditioner polyacrylic acid (PAA); group 3- samples were treated with 38 % SDF; group 4-samples protected by 3.8 % SDF; group 5- topical application of 38 % SDF along with and potassium iodide (KI) and group 6- DD was treated with PDT. All specimens were bonded to RMGIC, light cured and subjected to shear bond testing in a universal testing machine. Debonded surfaces were observed under optical microscopy at 40x magnification for failure modes. SBS was examined using analysis of variance (ANOVA) with Post-hoc test. For all test p-value less than 0.5 was considered statistically significant.Results: Bond strength in group 5 specimens, (38 % SDF and KI - 15.91 +/- 0.71 MPa) was significantly higher among all study groups (p 0.05). The minimum SBS observed in group 1 samples, (mineralized dentin bonded to RMGIC- 7.44 +/- 0.29 MPa) was significantly lower among tested treatment regimes. Samples in group 2 (DD conditioned with PAA and bonded to RMGIC) (11.39 +/- 0.54 MPa), group 3 (DD treated with 38 % SDF) (12.42 +/- 0.77 MPa) and group 6 (PDT treated DD) (11.52 +/- 0.86 MPa) exhibited comparable outcomes (p 0.05).Conclusion: Demineralized dentin (DD) treated with 38 % SDF and potassium iodide when bonded to RMGIC exhibited improved bond strength compared to other treatment regimes. Use of methylene blue photosensitizer for PDT, compromised adhesive integrity applied on DD.
