Abstract:
20 first mandibular premolars were randomly divided into 2 groups(n =10).The teeth in experimental group were treated by fi-ber main post in combination with auxiliary pile,in control group by single fiber main post,and then were restored by metal crown.They were fixed in universal testing machine.The fracture load(N)of experimental and control group was (846.50 ±40.33)and (437.90 ±41.15) respectively(P <0.01).
