Suez Canal University

Status: Completed

Conditions: Endodontic Re-treatment Failure

Details and patient eligibility

About

The aim of this study was to evaluate the effect of guided endodontic microsurgical root end resection on bone healing compared to nonguided microsurgery using two different retrograde filling material (Well root putty, MTA) by cone-beam computed tomography.

Enrollment: 24 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Tooth is restorable pocket depth is less than 4mm and mobility in its normal limit ( less than 1mm)
• Persisting or emerging disease following root-canal treatment when root canal re-treatment is inappropriate.
• Tooth with acceptable endodontic treatment and have a new post and crown restoration, but have a persistent or enlarging periapical lesion ( size less than 10 mm)
• Obstructed canal (the obstruction proved not to be removable, by passed and the risk of damage was too great).
• Extruded material or instrument with clinical or radiological findings of apical periodontitis and/or symptoms are present.

Exclusion criteria

• Non restorable tooth
• Contraindicating medical condition ( severe systemic condition and psychological condition)
• Anatomical contra indication
• Poor general oral status and supporting periodontal tissue.
