Statement of problem. The durability of a restoration is largely based un maintenance of the tooth/restoration interface which may lead to marginal integrity breakdown, microleakage, and staining and secondary caries.
Purpose. The purpose of this study was iu determine if fluorinated dental bonding resins will reduce composite resin marginal microleakagc
Materials and Methods, LighE-cnre filled and unfilled bonding resins were prepared from n basis resin nf45 bis-EMA, 40 TEGDMA, Lind 15^ HEMA. Fluorinated TEGDMA, 0-30 wt was substituted for some TEGDMA. Class V restorations were made. in 50 extracted human molar teeth, 3 mm length X 2 mm width X 1.5 mm depth centered on the cemento-enainel junction using 8 experimental formulations and 2 commercial bonding icsins (n = 5) Following a standard clinical protocol. The teeth were thermocycled 1500 times between 5 "C and 55 '"'C with 1-minute dwell times. Teeth were removed, dried, varnished, and placed in 50 silver nitrate solution at 37 '"C for 24 honrs in total darkness. The teeth were rinsed and sectioned through the. restorations with a di-amond .saw yielding haves. For each half, dye penetration was assessed under 80-power .stereo-scopic microscope and measured in mm from margin to axial wall for occlusal and cervical mar-gins.
Result. The data v/as analyzed statistically (p<0.05) using ANOVA. At the occlusal margins, commercial and non fluorinated bonding resins leaked significantly less (p |
