Bone Regenerative Techniques in Endodontic Microsurgery

Healing After Endodontic Microsurgery Using Resorbable Collagen Based Bone Augmentation Material: A Randomized Controlled Clinical Trial

The purpose of this randomized controlled clinical trial was to evaluate two dimensionally and 3-dimensionally the effect of resorbable collagen-based bone filling material on periapical healing following endodontic microsurgery (EMS) on endodontic lesions presenting four-wall defect.

Inclusion Criteria:

• Healthy adult.
• Intact coronal restoration with no sign of leakage.
• Class B (small lesion) and C (large lesion) periapical lesions. (Kim and Kratchman 2006)

Exclusion Criteria:

• Patients with medical conditions and contraindications to surgery.
• Minors.
• Pregnancy.
• Teeth with signs of coronal leakage.
• Teeth with vertical root fractures.
