The coronary sealing, next to root canal obturation, permits an appropriate environment to the periapical tissues repair, which is the major endodontic treatment’s outcome. Furthermore, good temporary sealing prevents new contamination between sessions of the endodontic treatment, also protecting the intracanal dressing. Many studies have been achieved for examining the marginal sealing of temporary restorations. This study intended to evaluate the marginal leakage in the coronary portion of teeth which suffered action of irrigating solutions used in endodontics, sealed with four different temporary materials. Sixty entire human premolars were divided into 5 experimental and 2 control groups according to each temporary restorative material used (Bioplic, Coltosol, XTempLC, IRM, Coltosol + instrumentation). The results indicated that all temporary materials used allowed a certain degree of infi ltration, however, Group II (Coltosol) showed the least index. It was also observed that irrigating solutions used during biomechanical preparationcan infl uence the marginal sealing, such as that observed in Group V which presented the greatest signifi cant marginal leakage
