Randomized clinical and radiographic trial

Evaluation of Autogenous Dentin Graft versus Demineralized Freeze-Dried Bone Allograft in the Treatment of Class ΙΙ and ΙΙΙ Mandibular Furcation Defects

Inclusion Criteria:

-

Presence of class II and/or ΙΙΙ furcation defects in mandibular first or second molars according to criteria outlined by Hamp et. al. 1975.

• Horizontal probing depth ≥3 mm using Naber's probe.
• Clinical attachment level ≥3 mm measured from cemento-enamel junction (CEJ) till the deepest probing depth.
• Evidence of radiolucency in the furcation area on panoramic radiograph.
• Patients who will be assigned for groups (I and II) should present with teeth required for extraction due to advanced periodontal bone loss or other indications such as hopeless wisdom teeth or orthodontic indications or unrestorable fractured teeth as a source for autogenous dentin graft (ADG).

Exclusion Criteria:

• Medically compromised patients and systemic conditions precluding periodontal surgery.

  • Mandibular first or second molars with root caries or endodontic treatment.
