Abstract

Aim

To evaluate and compare the efficacy, cleaning ability of hand and two rotary systems in root canal retreatment.

Methodology

Sixty extracted premolars were retreated with following systems: Group 1—ProTaper Universal retreatment files, Group 2—ProFile system, Group 3—H-file. Specimens were split longitudinally and amount of remaining gutta-percha on the canal walls was assessed using direct visual scoring with the aid of stereomicroscope. Results were statistically analyzed using ANOVA test.

Results

Completely clean root canal walls were not achieved with any of the techniques investigated. However, all three systems proved to be effective for gutta-percha removal. Significant difference was found between ProTaper universal retreatment file and H-file, and also between ProFile and H-file.

Conclusion

Under the conditions of the present study, ProTaper Universal retreatment files left significantly less guttapercha and sealer than ProFile and H-file.

Clinical significance

Rotary systems in combination with gutta-percha solvents can perform superiorly as compared to the time tested traditional hand instrumentation in root canal retreatment.
