摘　　要：The purpose of this study was to compare the sealing ability and marginal adaptation of four re-storative materials (MTA, Biodentine, portlant cement, and resin modified glass ionomer cement) used to repair iatrogenic furcation perforations. Eighty-four molars were treated endodontically, perforated in the middle of the pulp chamber floor with a round bur and separated randomly into 4 groups of 20 teeth each, while 4 teeth were used as positive and negative controls. The teeth were embedded in a moistened flower sponge and the perforations were filled with the appropriate restorative materials: Group 1: Biodentine;Group 2: MTA Angelus;Group 3: GC Fuji lining LC Paste Pak;Group 4: Aquafix Portland cement. The teeth remained in the soaked sponge for 28 days and then were submerged in basic fuchsine solution 1% for 48 hours. Dye penetration was evaluated after longitudinal sectioning of the teeth. Statistical analysis revealed that perforations restored with MTA exhibited the least microleakage with statistically significant difference among the other three groups (p < 0.05). The worst sealing ability was observed in the teeth restored with Aquafix Portland cement. No statistically significant difference was found between the groups of Biodentine and FC Fuji Lining Paste (p = 0.066).The purpose of this study was to compare the sealing ability and marginal adaptation of four re-storative materials (MTA, Biodentine, portlant cement, and resin modified glass ionomer cement) used to repair iatrogenic furcation perforations.
