Effect of halogene light source on marginal microleakage of resin composite restorations

Although the technology of production resin composite materials has been improved in the past years, polymerization shrinkage and microleakage still remain the main problem of the resin composite restorations.

| description | Introduction. Although the technology of production resin composite materials has been improved in the past years, polymerization shrinkage and microleakage still remain the main problem of the resin composite restorations. The most important issues are polymerization control, light source choice, quality and polymerization technique. The aim of this study was to evaluate the effect of the halogen light source on the marginal microleakage of the resin composite restorations class V. Material and Methods. The study included 40 extracted human teeth (20 intact and 20 with caries lesion). Class V cavity was prepared in each tooth. The light curing unit used in this study had irradiance 540 mW/cm2. Cavities were restored with the two resin composite materials, Filtek Supreme (3M ESPE) and Luksogal - Galenika. Microleakage was determined using colored solution of 50% silver-nitrate. Results were obtained using stereomicroscope with 6 times magnification. Color penetration was evaluated on the occlusal and gingival wall. Results. Linear color penetration was observed in all cavities restored using Luksogal. There was significant difference (p<0.01) in color penetration between the occlusal (20.30 μm) and gingival wall (34.00 μm). Color penetration was shown in all cavities prepared on intact and caries teeth and restored using Filtek Supreme. Also, color penetration on the occlusal wall (13.80 μm) was significantly lower (p<0.01) than the penetration on the gingival wall (33.00 μm). Conclusion. All the tested cavities showed marginal leakage, regardless the tooth or material used. Greater microleakage was noticed when Luksogal was used. |
