[PMID: 38962931 DOI: 10.1111/jre.13321] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2024] [Revised: 06/18/2024] [Accepted: 06/21/2024] [Indexed: 07/05/2024]
Abstract
AIM To evaluate whether the ribosome-crosslinked collagen membrane (RCCM) is non-inferior to the natural collagen membrane (NCM) used in regeneration surgery in terms of clinical attachment level (CAL) gain at 6 months. METHODS Eighty patients diagnosed as generalized periodontitis presenting with isolated infrabony defect (≥4 mm deep) were enrolled and randomized to receive regenerative surgery, either with NCM or RCCM, both combined with deproteinized bovine bone mineral (DBBM). CAL, pocket probing depth (PPD), and gingival recession (GR) were recorded at baseline, 3, and 6 months postoperatively. Periapical radiographs were taken at baseline, immediately, and 6 months after surgery. Early wound healing index (EHI) and patients' responses were recorded at 2 weeks postoperatively. RESULTS At 6 months post-surgery, the mean CAL gain was 3.1 ± 1.5 mm in the NCM group and 2.9 ± 1.5 mm in the RCCM group, while the mean PPD was 4.3 ± 1.1 mm in the NCM group and 4.2 ± 1.0 mm in the RCCM group. Both groups demonstrated a statistically significant improvement from the baseline (p < .01). RCCM was non-inferior to NCM concerning the primary outcome (CAL gain at 6 months). The GR at 6 months postoperatively was 1.3 ± 1.2 and 1.2 ± 1.1 mm, which showed no difference compared with baseline. At 6 months follow-up, the radiographic linear bone fill (RLBF) was 6.5 ± 2.8 and 5.5 ± 2.6 mm (p > .05), while the bone fill percentage (BF%) was 102.3 ± 53.5% and 92.3 ± 40.1% (p > .05), in the NCM and RCCM groups, respectively. There was no significant difference in EHI and postoperative responses between two groups. CONCLUSION RCCM + DBBM resulted in no-inferior clinical and radiographic outcomes to NCM + DBBM for the treatment of isolated infrabony defect in 6 months.

Yuan S, Yang X, Wang X, Chen J, Tian W, Yang B. Injectable Xenogeneic Dental Pulp Decellularized Extracellular Matrix Hydrogel Promotes Functional Dental Pulp Regeneration. Int J Mol Sci 2023; 24:17483. [PMID: 38139310 PMCID: PMC10743504 DOI: 10.3390/ijms242417483] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2023] [Revised: 12/09/2023] [Accepted: 12/12/2023] [Indexed: 12/24/2023] Open
Abstract
The present challenge in dental pulp tissue engineering scaffold materials lies in the development of tissue-specific scaffolds that are conducive to an optimal regenerative microenvironment and capable of accommodating intricate root canal systems. This study utilized porcine dental pulp to derive the decellularized extracellular matrix (dECM) via appropriate decellularization protocols. The resultant dECM was dissolved in an acid pepsin solution to form dECM hydrogels. The analysis encompassed evaluating the microstructure and rheological properties of dECM hydrogels and evaluated their biological properties, including in vitro cell viability, proliferation, migration, tube formation, odontogenic, and neurogenic differentiation. Gelatin methacrylate (GelMA) hydrogel served as the control. Subsequently, hydrogels were injected into treated dentin matrix tubes and transplanted subcutaneously into nude mice to regenerate dental pulp tissue in vivo. The results showed that dECM hydrogels exhibited exceptional injectability and responsiveness to physiological temperature. It supported the survival, odontogenic, and neurogenic differentiation of dental pulp stem cells in a 3D culture setting. Moreover, it exhibited a superior ability to promote cell migration and angiogenesis compared to GelMA hydrogel in vitro. Additionally, the dECM hydrogel demonstrated the capability to regenerate pulp-like tissue with abundant blood vessels and a fully formed odontoblast-like cell layer in vivo. These findings highlight the potential of porcine dental pulp dECM hydrogel as a specialized scaffold material for dental pulp regeneration.

Bioengineering (Basel) 2023; 10:929. [PMID: 37627814 PMCID: PMC10451653 DOI: 10.3390/bioengineering10080929] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2023] [Revised: 07/11/2023] [Accepted: 07/21/2023] [Indexed: 08/27/2023] Open
Abstract
BACKGROUND Bone defect therapy is a common clinical challenge for orthopedic and clinical physicians worldwide, and the therapeutic effect affects the physiological function and healthy life quality of millions of patients. Compared with traditional autogenous bone transplants, bone xenografts are attracting attention due to their advantages of unlimited availability and avoidance of secondary damage. However, there is currently a lack of bibliometric analysis on bone xenograft. This study aimed to use bibliometric methods to analyze the literature on bone xenograft from 2013 to 2023, to explore the current status, hotspots, and future trends of research in this field, and to promote its development and progress. METHODS Using the Web of Science Core Collection database, we retrieved and collected publication data related to xenogeneic bone grafting materials worldwide from January 2013 to March 2023. Origin (2021), CiteSpace (6.2.R2 standard), and an online bibliometric platform were used for bibliometric analysis and data visualization. RESULTS A total of 3395 documents were retrieved, and 686 eligible papers were selected. The country and institutions with the highest number of publications and centrality were the United States (125 papers, centrality = 0.44) and the University of Zurich (29 papers, centrality = 0.28), respectively. The most cited author was Araujo MG (163 times), and the author with the most significant centrality was Froum SJ (centrality = 0.09). The main keyword clusters were "tissue engineering", "sinus floor elevation", "dental implants", "tooth extraction", and "bone substitutes". The most significant bursting keywords in the last three years were "platelet rich fibrin". CONCLUSIONS Research on bone xenograft is steadily growing and will continue to rise. Currently, research hotspots and directions are mainly focused on dental implants related to bone-augmentation techniques and bone tissue engineering. In the future, research hotspots and directions may focus on decellularization technology and investigations involving platelet-rich fibrin.
