AI Article Synopsis

  • An animal study on Beagle dogs investigated the healing of tooth extraction wounds by comparing two methods of treatment: a combination of beta-tricalcium phosphate (Cerasorb) and platelet rich plasma (PRP) versus Cerasorb alone.
  • Biopsy samples were taken at 6, 12, and 24 weeks post-surgery to assess bone regeneration through histological analysis.
  • Results indicated that the combination of Cerasorb and PRP led to significantly denser new bone after 6 weeks, with the difference decreasing over time, suggesting that adding PRP enhances early bone healing in extraction sites.

Article Abstract

Healing of extraction wounds was examined in an animal experiment model on Beagle dogs. After bilateral extraction of the premolars of 12 dogs the alveoli were filled up with a combination of beta-tricalcium phosphate (Cerasorb) graft and platelet rich plasma (PRP) on the experimental side, and with Cerasorb alone on the control side. Biopsy specimens were taken from the regenerating bone at 6, 12 and 24 weeks after surgery for histological study. Results of the histologic and histomorphometric examinations revealed that after 6 weeks the newly formed bone was significantly denser on the experimental side. After 12 weeks this difference became moderate, and after 24 weeks the bone forming activity was nearly equal on the two sides. These results suggest that local administration of Cerasorb and PRP results in more intense bone regeneration, especially in the early phase.

MXenes, with their good biocompatibility, excellent photovoltaic properties, excellent physicochemical properties, and desirable bioactivity, have broad application prospects in the field of tissue regeneration. MXenes have been used in a wide range of applications including biosensing, bioimaging, tumour/infection therapy, bone regeneration and wound repair. By applying bioactive materials to modify the surface of MXenes, a series of multifunctional MXene-based nanomaterials can be designed for different biomedical applications to achieve better therapeutic effects or more desirable biological functions.

Background/purpose: Bone reconstruction in the maxillofacial region typically relies on autologous bone grafting, which presents challenges, including donor site complications and graft limitations. Recent advances in tissue engineering have identified highly pure and proliferative dedifferentiated fat cells (DFATs) as promising alternatives. Herein, we explored the capacity for osteoblast differentiation and the osteoinductive characteristics of extracellular vesicles derived from DFATs (DFAT-EVs).

Background/purpose: Bisphosphonate-related osteonecrosis of the jaw (BRONJ), a complication arising from the use of bisphosphonates (BPs), inflicts long-term suffering on patients. Currently, there is still a lack of effective treatments. This study aimed to explore the preventive effects of propranolol (PRO) on BRONJ in vitro and in vivo, given PRO's potential in bone health enhancement.

Background/purpose: Revascularization procedures are used over apexification to treat teeth with necrotic pulp tissues and incomplete root formation. Clinically, inducing proliferation, migration, matrix deposition, and differentiation of stem cells from apical papilla (SCAPs) are critical for pulp regeneration. The study aimed to elucidate the impact of bone morphogenetic protein-4 (BMP-4) on plasminogen activation molecules and the osteogenic/odontogenic differentiation of SCAPs, as well as understand the related signaling mechanisms.
