Objective.
Comparing effect of different restoration techniques on fracture resistance of compromised roots.
Methods.
Crowns of 100 single-rooted teeth were sectioned and 10 roots were kept as negative control group (Group 1).
Remaining roots were instrumented and divided into one and positive control group of 10 samples (Group 2) and 4 experimental groups of 20 samples each.
Group 3: roots were obturated with gutta-percha; Group 4: roots were restored with gutta-percha, composite, and glass fiber post; Group 5: roots were obturated with Resilon; Group 6: Roots were restored with Resilon, composite, and glass fiber post.
Roots were weakened before obturation in groups 2, 3, and 5 and after obturation in groups 4 and 6.
Fracture strengths were measured using Dartec testing machine and fracture load was recorded in kilo-Newton.
Statistical analysis was done using ANOVA and Tukeys test.
Results.
The fractures resistance of restored roots was significantly higher in groups 4, 5, and 6 than in Groups 2 and 3.
There were no significant differences between groups 1, 4, 5, and 6.
Conclusions.
Restoration of weakened roots with Resilon or bonding an intermediate composite resin to coronal radicular dentin and to glass fiber post increased their fracture resistance.
