Pit and fissure sealing (PFS) has been established as an effective and cost-efficient preventive intervention, yet service coverage remains suboptimal in China. This study examines guardians' preferences and preference heterogeneity regarding PFS services, with the aim of informing tailored service delivery and policy interventions to enhance PFS uptake.</p><p><strong>Methods: </strong>A discrete choice experiment was conducted through face-to-face interviews with 411 guardians. Four key attributes were included: preventive effectiveness, preventive service time, distance and out-of-pocket (OOP) service cost. Data were analysed using a mixed logit model, subgroup analyses and scenario analyses were performed to examine preference heterogeneity.</p><p><strong>Results: </strong>Preventive effectiveness (41.31%) emerged as the most influential attribute, followed by distance (29.23%), OOP service cost (15.85%) and preventive service time (13.61%). Female guardians and guardians of children with poor oral health status placed greater emphasis on preventive effectiveness and distance. In contrast, male guardians were more focused on OOP service cost. Guardians with higher education levels and guardians of children with better oral health status were more inclined to schedule PFS services during vacations. The scenario analysis revealed that guardians prefer PFS services with general effectiveness but higher accessibility and lower OOP costs, rather than those offering superior effectiveness but compromised accessibility and higher financial burden. Notably, medical insurance coverage boosted service uptake from 18.3% to 71.0%, with guardians willing to pay 127 Chinese yuan more for insured services.</p><p><strong>Conclusion: </strong>These findings highlight substantial preference heterogeneity among guardians and underscore the transformative potential of insurance coverage in enhancing service accessibility.

Green synthesis methods, which are eco-friendly and non-toxic, have gained attention for the production of nanocomposites. Silymarin, a bioactive compound, can serve as both a reducing and stabilizing agent in such synthetic processes. In this study, we aimed to develop a nanohydroxyapatite nanocomposite using silymarin (SL) and chitosan (CH) and evaluate its antioxidant, antibacterial, and anti-inflammatory properties for oral health applications.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;Nanohydroxyapatite nanocomposites were synthesized using a green synthesis technique, with silymarin acting as both reducing and stabilizing agent. Chitosan was incorporated to form the polymer-based nanocomposites. The synthesized materials (silymarin-chitosan, silymarin-nHAP, and nanocomposite) were characterized by Transmission Electron Microscopy (TEM), Scanning Electron Microscopy (SEM), and Fourier Transform Infrared Spectroscopy (FTIR) to assess their morphology and functional groups. Antioxidant activity was evaluated using the DPPH assay, and the antibacterial activity was tested against common oral pathogens. Biocompatibility was assessed using human gingival fibroblast (HGF) cells and cell viability was measured via live/dead cell assays using fluorescence imaging and in vitro migration assays. Wettability analysis was performed using a contact angle measurement technique to evaluate the surface hydrophilicity of the nanocomposite, a crucial factor for biointegration and tissue adhesion. Additionally, the anti-inflammatory potential was examined using the human red blood cell (HRBC) membrane stabilization assay, where the nanocomposite was evaluated for its ability to inhibit heat-induced hemolysis.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;The characterization revealed the successful formation of nanoHA nanocomposites with distinct morphological features. Antioxidant assays indicated significant free radical scavenging activity, whereas antibacterial testing demonstrated effective inhibition of oral pathogens, including Streptococcus mutans and Porphyromonas gingivalis. Wettability analysis revealed a favorable contact angle, indicating enhanced surface hydrophilicity, which is beneficial for cell attachment and biointegration. Biocompatibility studies revealed that the nanocomposites exhibited minimal cytotoxicity and enhanced cell viability. Migration assays revealed favorable activity in promoting fibroblast migration, suggesting its potential for tissue regeneration. Furthermore, the HRBC membrane stabilization assay confirmed the anti-inflammatory potential of the nanocomposite, indicating its ability to protect erythrocytes against heat-induced hemolysis.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;The silymarin-chitosan-nanohydroxyapatite nanocomposite synthesized using green methods demonstra","PeriodicalId":9072,"journal":{"name":"BMC Oral Health","volume":"25 1","pages":"1617"},"PeriodicalIF":3.1,"publicationDate":"2025-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145290917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
