| Abstract | ||||
| Aim: The aim of this study was to compare the outcome of minimally invasive approach (MIA), retaining the separated in one root canal, cleaning and shaping of portals of entry of the two canals and portal of exit of both canals through the other patent canal, in comparison to the outcome of retrieval of the broken instrument by ultrasonics retrieval techniques (URT). Material and Methods. Ninety-six study cases with separated instrument were selected in canals with type II Vertucci's classification. The cases were randomly divided into two groups; group (C): conservative root canal retreatment in which the canal with broken file was negotiated to the coronal level of the separated instrument without any attempt of retrieval and group (T): traditional root canal retreatment in which attempt to retrieve the separated instrument was done using ultrasonics and available instrument retrieval systems. The peri-radicular condition was evaluated radiographically using the Periapical Index (PAI) for one year. The chi-square test statistical tests analyzed the outcome data. Results. At the baseline examination, There was no significant difference between the two groups regarding the patients’ baseline mean periapical indices . After one year, we found that the mean periapical index declined without a significant difference between the two groups. Conclusion. Within the limitations of this study, it was concluded that conservative management of separated Instruments in canals with type II Vertucci's classification is considered successful “minimally invasive alternative” as traditional management of the cases using ultrasonics attempts of retrieval. | ||||
