Brief Summary

The study compares the prognosis of cases of Separated Instruments in Canals With Type II Vertucci's Classification treated with conservative approach

Detailed Description

Teeth with Type II Vertucci root canal configuration are having more incidence of instruments separation due the presence of an S-type (Double curve). The aim of this study is 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)

Conditions

Teeth, Endodontically-Treated

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: SINGLE

Study Groups

conservative treatment

The patent canal is retreated, no attempt to deal with the separated instrument

Group Type: EXPERIMENTAL

Endodontic retreatment

Intervention Type: PROCEDURE

retreatment of the patent root canal only without attempt to retrieve the separated instrument

traditional

All canals are retreated with attempts to retrieve the broken file

Group Type: ACTIVE_COMPARATOR

Endodontic retreatment

Intervention Type: PROCEDURE

retreatment of the patent root canal only without attempt to retrieve the separated instrument

Interventions

Endodontic retreatment

retreatment of the patent root canal only without attempt to retrieve the separated instrument

Intervention Type: PROCEDURE

Eligibility Criteria

Inclusion Criteria

Exclusion Criteria

• • Patients who refused to undergo radiographic follow-up.

• Pregnant females.
• Patients suffered from a systemic disease.
• Teeth with lesions connected to adjacent teeth.
• Teeth with root fractures or perforations.
• Teeth with lesion communicating with the alveolar crest.
• patients with generalized chronic periodontitis or teeth that need periodontal surgery prior to coronal restorations due to marginal deficiency
• teeth with damaged or resorbed peri- apex
• teeth that were treated with a fiber post and teeth with canal curvature more than 25 degrees
