Demineralized Dentin Allograft Versus Demineralized Dentin Autograft for Socket Preservation

The Demineralized Dentin Allograft Versus Demineralized Dentin Autograft for Socket Preservation After Surgical Extraction of Impacted Mandibular Third Molar

This study is designed to evaluate and compare clinically and radiographically the effectiveness of Demineralized Dentin Allograft (DDA) versus Demineralized Dentin Autograft (Auto-DD) for preservation of alveolar ridge dimensions after surgical extraction of the impacted mandibular third molar.

Inclusion Criteria:

1. Patients aged between 25 to 35 years old.
2. Patients scored as (ASA I).
3. No adverse habits such as smoking, tobacco chewing, alcohol.
4. Patients having bilaterally impacted mandibular third molar with similar degree of difficulty according to (Kim JY, et al).
5. The recipient alveolar sockets are free of any pre-existing periapical pathology, based on x-ray.
6. Alveolar sockets with a depth of 5 mm or more, using periodontal probe for assessment.
7. Patients sign a consent for all procedures.

Exclusion Criteria:

• 1) Pregnant or lactating patients. 2) Relevant systemic diseases. 3) Patients with history of chemotherapy or radiotherapy.
