Abstract EN
Aim.
The aim of this study was to compare the fracture resistance of simulated immature teeth restored with gutta-percha, glass fiber posts (GFP), experimental dentine posts (DP) or Intracanal composite Resin (ICR).
Materials and Methods.
Fifty maxillary canines were decoronated, standardized and enlarged until, number 5 Peeso reamers were allowed to simulate immature teeth.
After placement of 5 mm of MTA, the canals were divided into 5 groups and filled as follows: Group 1: AH Plus + gutta-percha, lateral compaction; Group 2: GFP luted with PARACORE dual cure resin; Group 3: DP luted with PARACORE dual cure resin; Group 4: PARACORE dual cure resin.
A standardized core was built in all groups except in Group 5.
Each of the specimens was tested for fracture resistance by universal testing machine.
Results.
The mean fracture resistance were 817 ± 27.753, 1164.6 ± 21.624, 994.4 ± 96.8747, 873.8 ± 105.446 and 493.7 ± 6.945 newtons for Groups 1, 2, 3, 4, and 5 respectively.
Independent “ t ” test revealed statistically significant discrepancies, in the fracture resistance among the 4 groups except Group 1 and Group 4 ( P < 0.05 ).
Conclusions.
This study suggests that GFP and DP may be preferred for additional reinforcement of immature teeth.
