However, due to its low bioavailability and unfavorable pharmacokinetics, analogous compounds have been developed to obtain better biopharmaceutical characteristics and enhanced biological effects. In this study, we evaluated the activity of curcumin and three of its synthetic analogues (DMAD, DMAM, and RI75) on the viability and differentiation of a pre-osteoblastic cell line (MC3T3-E1). We also assessed the expression of key genes involved in tissue regeneration: vascular endothelial growth factor (vegf), stromal-derived growth factor 1 (SDF-1/CXCL12), and runt-related transcription factor 2 (runx2). The cells were treated with curcumin and the three analogues at concentrations of 10, 30, or 50 μM. All tested analogues and curcumin exhibited moderate to no cell toxicity compared to the cells treated under standard conditions across all concentrations after 24, 48, and 72 hours. Only the RI75 analogue showed upregulation of SDF-1, a crucial factor in tissue regeneration. Compared to curcumin, the DMAM and RI75 analogues also upregulated runx2 and vegf, both associated with osteodifferentiation. The RI75 analogue demonstrated greater mineralization than curcumin, and both promoted more nodule formation than the untreated control. Our data suggest that the curcumin analogue RI75 at 50 μM presents similar toxicity but enhanced biological activity compared to natural curcumin, making it a promising substance for material biomodifications.</p>","PeriodicalId":9240,"journal":{"name":"Brazilian oral research","volume":"38 ","pages":"e123"},"PeriodicalIF":1.5,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11654880/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142812018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results indicated no significant differences in flexural strength (p > 0.05) among groups. CG exhibited the lowest erosion scores in the cervical third.

This study aimed to quantify socioeconomic inequalities in early childhood caries (ECC) and examine the potential role of daily fluoride-toothpaste use, previous-year dental-care visit, and nutrition/diet-related aspects. The study sample included 1344 children aged 1-5 years. Inequalities in the age-standardized prevalence rates of and mean number of tooth surfaces affected by moderate/extensive (dME) and initial (dIME) caries (defined using the ICDAS-merged-epi criteria) by household income and level of education were examined using the relative index of inequality (RII) and the slope index of inequality (SII). Approximately one-third of the children included in this study exhibited dME, while 84% exhibited dIME. The majority of outcomes exhibited social gradients, and significant relative (RII) and absolute (SII) inequalities in ECC were observed. The SII estimate indicated an absolute difference of 12.4% in the prevalence of moderate/extensive carious lesions among children living in households with the lowest compared to the highest education levels [SII: 12.4; 95% confidence interval (CI): 2.7-22.1]. These children were also 6.7 times more likely to exhibit dIME compared to those living in households with higher levels of education (SII:6.73 95% CI: 4.18-9.29). Daily use of fluoride toothpastes, dental care visits in the previous year, and nutrition/diet-related factors played a limited role in ECC inequalities.
