    Objective: To investigate associations/correlations between bone alterations and vitamin D status in children through data mining analyses based on observational studies. Material and Methods: Searches in PubMed, Scopus, Web of Science, and Embase databases were performed to recover studies, published until October 2022, with healthy children, which investigated the vitamin D status, related or not to undesirable bone alterations linked to bone quality (bone mineral density and bone mineral content), fracture or anthropometry. Country, study design, area of expertise (medicine, nutrition, dentistry, others), bone outcome, 25-hydroxyvitamin D data (serum or intake levels), the exams for bone diagnosis, and the results were analyzed in the VantagePointTM software. Results: Of 20,583 studies, 27 were included. The USA (n=9; 33.3%) had the highest number of publications. Cross-sectional (n=11; 40.7%), case-control (n=9; 33.3%), and cohort studies (n=7; 25.9%) contemplated the medicine and nutritional areas without any study in dentistry. Studies about bone quality (n=21; 77.8%), analyzed through dual-energy X-ray absorptiometry (DXA; n=14; 51.8%), with association (n=16; 59.2%) between the low serum levels of 25-hydroxyvitamin D and undesirable bone alterations (n=14; 51.8%) were the most prevalent. Conclusion: Most studies were conducted in the medical area and showed an association between low bone quality and low levels of 25-hydroxyvitamin D, verified through DXA

    To evaluate the antifungal activity of the red propolis hydroalcoholic extract (RPHE) against Candida albicans biofilms. The minimum inhibitory and fungicidal concentrations (MIC and MFC) of the RPHE were determined by the microdilution technique. C. albicans biofilms were formed on the surface of resin specimens preconditioned with artificial saliva (1h). The specimens (N=48) were equally divided according to the four solutions used for anti-biofilm evaluation (n=12 per group). After overnight incubation, biofilms were daily exposed (2x/day for 15 min) along 3 days with 3% RPHE, 0.12% chlorhexidine (CHX), 50,000 IU/mL nystatin (NYS) or saline (0.9% NaCl). Biofilms were analyzed regarding the number of viable microorganisms (CFU/mL), the metabolic activity (MTT assay) and the proportion of hyphae (optical microscopy). The MIC and MFC of RPHE were respectively 0.29 mg/mL (0.03%) and 1.17 mg/mL (0.12%). There was no difference in the microorganisms? viability (CFU/mL) among groups treated with RPHE (4.92×103), CHX (3.33×102) or NYS (6.8×104), being all of them different from NaCl (3.93×107) (p0.05). All experimental groups had a mean proportion of hyphae <10%, lower than NaCl (70%). RPHE has antifungal activity against C. albicans biofilms, suggesting its use for the biofilm control on denture surfaces

    To evaluate the prevalence of oral cancer in Brazil according to the clinical stage, anatomical location, alcoholism and smoking. Data referring to 31,217 cases of oral cancer, from 2000 to 2010, were obtained from the Integrator Module of the Hospital Registry of Cancer. Inconsistent data (?non-classified? cases) was eliminated and 21,160 cases were analyzed. The frequency distribution according to clinical stage, anatomical location, alcoholism and smoking was analyzed descriptively and through a binary logistic regression model (?<0.05). The clinical stage (dependent variable) was dichotomized in early stage (I and II) or advanced stage (III and IV). The year of diagnosis, anatomical location and deleterious habits (alcoholism and smoking) were considered independent variables. The most frequent characteristics were: oropharynx location (n=3856, 18.41%), clinical stage IV (n=11924, 56.09%) and combined use of alcohol and tobacco (n=19226; 61.59%). The year 2009 (p<0.01, PR = 1.162, CI-95%=1.053-1.283) and location at the base of tongue (p<0.01, PR = 2.485, CI-95% = 2.182-2.807) presented a higher prevalence ratio for advanced stage oral cancer. The combined use of alcohol and tobacco showed a higher prevalence rate for the advanced clinical stage of cancer (p<0.01, PR =1.449, CI-95%=1.382-1.520) if compared to individuals without habits, or just alcoholics. Higher prevalence of advanced stage of oral cancer is related to the localization at the base of the tongue and to the concomitant use of alcohol and tobacco. Therefore, it can be suggested that all these characteristics lead to a worse prognosis of oral cancer
