Outcome Measures
Primary Outcomes (1)
monitoring of periapical index
The peri-radicular condition was evaluated using the Periapical Index (PAI) created by Ørstavik et al. (1986). The PAI includes five grades represented on an ordinal scale as follows: (1) normal periapical structures; (2) small changes in the periapical bone or bone structure; (3) changes in the periapical bone structure with mineral loss, characteristic of apical periodontitis; (4) demineralization of the periapical bone within a well-defined radiolucent area; and (5) demineralization of the periapical bone with exacerbations and expansion in bone structure.

Study Arms (2)
conservative treatment
EXPERIMENTALThe patent canal is retreated, no attempt to deal with the separated instrument
traditional
ACTIVE COMPARATORAll canals are retreated with attempts to retrieve the broken file
Interventions
retreatment of the patent root canal only without attempt to retrieve the separated instrument
Eligibility Criteria
You may qualify if:
- Presence of separated instrument in a root with a Vertucci's type II configuration (the level of the SI was evaluated using CBCT scans)
- Age range 35-55 years
- Teeth having a baseline periapical lesion (PAI score ≥2) in the affected root
You may not qualify if:
- 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
