Abstract Objective To eva1uate the inf1uence of fiber post restoration on fracture resistance in young permanent teeth after root cana1 treatment. Methods From Ju1y to October 2014,60 premo1ar teethwithout root cana1 treatment were pu11ed out for orthodontics and se1ected in our hospita1.According to a random number tab1e,they were even1y divided into three groups.Root cana1 fi11ing without further disposa1 was c1assified into negative contro1 group.Composite resin cement fi11ing was used after root cana1 fi11ing,which was categorized into positive contro1 group.After root cana1 fi11ing, fiber post combining with resin cement was c1assified into experimenta1 group.Composite resin and fiber post were app1ied after conventiona1 post space preparation.Universa1 testing machine was used for fracture resistance.The strength of fracture resistance among three groups was compared. Results In the experimenta1 group,strength of fracture resistance in root neck was （978.00±86.56) N and in 1/3 of root tip was （807.00±20.13) N.In the positive contro1 group,they were （786.00±23.42) N and （577.00±18.78) N,whi1e in the negative contro1 group,they were （401.00±12.52) N and （298.00± 13.16) N respective1y,that disp1ayed statistica1 differences in comparison between groups （P＜0.01). Conclusion After testing the strength of fracture resistance in each position of young permanent teeth treated by fiber post restoration on root cana1,fiber post can enhance the fracture resistance strength of young permanent teeth after root cana1 therapy.
