Bakhrushina, Natalia Kireeva, Sergey Dydykin, Yuriy Vasil’ev PMC · DOI: 10.3390/jfb17020092 · 2026-02-13 ## TL;DR This paper reviews collagen-based delivery systems for preventing alveolitis after tooth extraction, highlighting their potential to reduce inflammation and promote healing. ## Contribution The paper provides a rationale for developing biopharmaceutical collagen-based systems tailored for oral conditions to prevent alveolitis. ## Key findings - Collagen-based systems can stabilize blood clots and reduce microbial contamination in extraction sockets. - These systems support tissue regeneration by promoting angiogenesis and osteogenesis during healing. - Topical collagen delivery shows potential for prolonged therapeutic effects in preventing alveolitis. ## Abstract Alveolitis remains a common postoperative complication following tooth extraction, characterized by inflammation and delayed socket healing. Collagen-based materials have shown promise in promoting tissue regeneration and reducing inflammation. This review evaluates the efficacy of collagen in the prevention of alveolitis, with a focus on the development and application of topical delivery systems such as gels and collagen sponges. Special attention is given to the local application of these systems within the extraction socket and their performance under oral conditions. The study analyzes current evidence on the pathogenesis of alveolitis, the biological properties of collagen relevant to wound healing, and pharmaceutical strategies for enhancing its clinical effectiveness. The findings support the feasibility of using biodegradable, site-specific collagen-based formulations for alveolitis prevention. Such systems may provide a prolonged therapeutic effect, stabilize blood clots, reduce microbial contamination, and support angiogenesis and osteogenesis throughout the healing process. This approach offers a promising direction for improving post-extraction management protocols in dental surgery. ## Full-text entities - **Genes:** FGF2 (fibroblast growth factor 2) [NCBI Gene 2247] {aka BFGF, FGF-2, FGFB, HBGF-2}, RHC [NCBI Gene 3057] - **Diseases:** immunodeficiencies (MESH:D007153), dry socket (MESH:D004368), cytotoxicity (MESH:D064420), Infection (MESH:D007239), postoperative complication (MESH:D011183), nerve dysesthesia (MESH:D010292), postoperative (MESH:D019106), allergic reactions (MESH:D004342), Alveolitis (MESH:D011658), infectious (MESH:D003141), pain (MESH:D010146), Complications (MESH:D008107), inflammation (MESH:D007249), injury to (MESH:D014947), swelling (MESH:D004487), inflammatory complications (MESH:D018746), trismus (MESH:D014313), diabetes (MESH:D003920), anaphylaxis (MESH:D000707) - **Chemicals:** hydroxyproline (MESH:D006909), Ateloplug (-), serine (MESH:D012694), Hydroxyapatite (MESH:D017886), amino acid (MESH:D000596), ribose (MESH:D012266), chitosan (MESH:D048271), proline (MESH:D011392), amoxicillin-clavulanic acid (MESH:D019980), vancomycin (MESH:D014640), PMMA (MESH:D019904), hyaluronic acid (MESH:D006820), chlorhexidine (MESH:D002710) - **Species:** Fusobacteriia (class) [taxon 203490], Homo sapiens (human, species) [taxon 9606], Rattus norvegicus (brown rat, species) [taxon 10116], Bos taurus (bovine, species) [taxon 9913], Equus caballus (domestic horse, species) [taxon 9796], Porifera (sponges, phylum) [taxon 6040], Proteus (genus) [taxon 210425], Echinoidea (sea urchin, class) [taxon 7625] ## Figures 2 figures with captions in the complete paper: https://tomesphere.com/paper/PMC12942239/full.md --- Source: https://tomesphere.com/paper/PMC12942239
