Comparison of the osteogenic effects of demineralized dentin matrix and acellular dentin matrix.

Objectives: This study aims to compare the osteogenic effects of implanting demineralized dentin matrix and acellular dentin matrix in bone defect areas.

Methods: Demineralized dentin matrix and acellular dentin matrix were prepared. Twenty-four male SPF-grade SD rats were randomly divided into four groups: demineralized group (group A), acelluar group (group B), Bio-Oss bone powder group (group C), and blank control group (group D), with six rats in each group.

[Evaluation of the consistency between the measurement results of residual bone height and root surface area in periodontal supporting tissue].

Purpose: To explore the percentage of residual support height (Ph) and the percentage of residual root surface area (Ps) in evaluating periodontal support ability by simulating different stages of periodontitis based on the curved surface modeling.

Methods: Fifteen cone-beam CT (CBCT) images including 420 teeth in total were collected. The data were reconstructed into 3-dimensional teeth models by Mimics software.
