| ABSTRACTBackground: The aim of this study was to assess the effect of modified Carisolv gel on micro leakage of repaired lightcured composite restoration with different time of application (5, 10 and 15) minutes.Materials and methods: Twenty eight specimens were prepared using translucent plastic mold of dimension (8 mmdiameter and 2.5 mm depth), divided into 4 groups according to application time of Carisolv gel. All specimenstreated with phosphoric acid 35% followed by Swisstec SL bond, GA (Carisolv 5 minutes + Swisstec total etch bond),GB(Carisolv 10 minutes + Swisstec total etch bond), GC(Carisolv 15 minutes + Swisstec total etch bond), GD controlgroup using Swisstec total etch bond without using of Carisolv gel. All specimens were stored in artificial salivasolution for one month, finishing of composite surface with coarse aluminum oxide abrasive disc, repair has beendone for all specimens, thermo cycling between two water baths (5±2 and 55±2)°C has been done. Specimenswere stored in bottles containing metylene blue dye for 2 days, sectioned with a special sectioning device.Microleakage was analyzed by reading the linear penetration of the dye in mm using stereomicroscope with areflected light under the magnification of 4X, data was collected an analyzed using ANOVA and t-test.Results: GC exhibited less micro leakage than GB, and GB showed less micro leakage than GA and GD showedhigher micro leakage than other groupsConclusion: Time of Carisolv gel application has a significant effect on microleakage, increasing exposure time to acertain limit decreases micro leakage.Key words: Carisolv, application time, composite repair.
