Demineralized Dentin Allograft Versus Demineralized Dentin Autograft for Socket Preservation

March 8, 2026 updated by: Mohamed Ali Habib, Horus University

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Measuring and comparing the height of bone between the two groups
Time Frame: Immediately post-operative, 3months post-operative, 6months post-operative
We will measure the height of the alveolar ridge clinically by using ridge mapping caliper (special caliper forceps used for measuring ridge dimensions) and radiographically on the cone-beam computed tomography (CBCT) and comparing the results of the study group (20 sockets) with the control group (the other 20sockets), to assess the effectiveness of Demineralized Dentin Allograft for ridge preservation
Immediately post-operative, 3months post-operative, 6months post-operative
Measuring and comparing the width of bone between the two groups
Time Frame: Immediately post-operative, 3months post-operative, 6months post-operative
We will measure the width of the alveolar ridge clinically by using ridge mapping caliper (special caliper forceps used for measuring ridge dimensions) and radiographically on the cone-beam computed tomography (CBCT) and comparing the results of the study group (20 sockets) with the control group (the other 20sockets), to assess the effectiveness of Demineralized Dentin Allograft for ridge preservation
Immediately post-operative, 3months post-operative, 6months post-operative

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Assess and comparing the mouth opening of both groups
Time Frame: One day post-operative, one week post-operative
Assess the mouth opening of the patient using a millimeter ruler (by measuring the distance between maxillary incisal edge and mandibular incisal edge) and comparing the results of both groups
One day post-operative, one week post-operative
Assess and comparing the swelling of both groups
Time Frame: One day post-operative, one week post-operative

Swelling levels after surgery will be measured using anatomic landmarks (Tragus-Labial commissure and Tragus-Pogonion), the distances between the landmarks used for the evaluation methods will be measured before the operation.

All measurements will be done using millimeter ruler, while the patient will be seated.

One day post-operative, one week post-operative
Assess and comparing the pain of both groups
Time Frame: One day post-operative, one week post-operative
we will use the Visual Analogue Scale (VAS) for pain measurement
One day post-operative, one week post-operative
Assess and comparing the soft tissue parameters (bleeding on probing and color of the gingiva) of both groups
Time Frame: One day post-operative, one week post-operative
The bleeding on probing will be assessed by using periodontal probe and this will be done around mandibular first and second molars
One day post-operative, one week post-operative
