Histologic Evaluation of Soft and Hard Tissue Healing Following Alveolar Ridge Preservation with Deproteinized Bovine Bone Mineral Covered with Xenogenic Collagen Matrix. | LitMetric
The purpose of this study was to histologically evaluate new bone formation and dimensional soft tissue changes of two different healing protocols (16 weeks and 32 weeks) using deproteinized bovine bone mineral (DBBM) covered with collagen matrix (CM) for alveolar ridge preservation in the anterior esthetic zone prior to dental implant placement. Compared to baseline, both treatments yielded statistically significant differences in several clinical parameters and in the microarchitecture of the native bone and in the newly formed bone in the augmented sites. However, the protocol at 32 weeks determined greater new vital bone formation and fewer dimensional tissue changes.
Introduction: Tooth extraction initiates a cascade of homeostatic and structural modifications within the periodontal tissues, culminating in alveolar ridge resorption. To prevent ridge resorption following extraction and facilitate successful placement of an implant-supported prosthesis, alveolar ridge preservation was performed.
Methods: In this study, the biocompatibility of a nanocomposite consisting of self-assembling peptide nanofibers (organic phase) and tri-calcium phosphate-nano hydroxyapatite (mineral phase), was evaluated in rabbits.

Purpose: To investigate the application value of periodontal microsurgery in accelerated osteogenic orthodontics (PAOO).
Methods: A total of 100 patients with the need of PAOO surgery before orthodontic treatment due to the lack of alveolar bone in the mandibular anterior area were selected and randomly divided into microsurgery group and control group with 50 cases in each group. Preoperative CBCT was used to measure the thickness and height of the alveolar bone as well as the gingival thickness.
Purpose: To compare the clinical efficacy of autologous bone block graft and guided bone regeneration (GBR) in horizontal bone augmentation.
Methods: A total of 42 patients were included and divided into two groups. Group A included 20 patients, in whom autologous bone block graft was performed.
Introduction: Alveolar macrophages (AM) are critical effectors of the immune response and are essential for host responses to . Changes in lipid metabolism in AM can alter cellular function and biology. Impaired metabolism can contribute to excessive lipid accumulation and pro-inflammatory signaling.
The increasing prevalence of obesity and metabolic disorders has created a significant demand for personalized devices that can effectively monitor fat metabolism. In this study, we developed an advanced breath analyzer system designed to provide real-time monitoring of exercise-induced fat burning by analyzing volatile organic compounds (VOCs) present in both oral and alveolar breath. Acetone in exhaled breath and β-hydroxybutyric acid (BOHB) in the blood are both biomarkers closely linked to the metabolic fat burning process occurring in the liver, particularly after exercise.
