Total 56 samples (5 mm diameter and 2 mm thickness) were prepared and divided into 4 groups according to the incorporation of chitosan and nanodiamond on Fuji II glass ionomer cement: Control group: no incorporation; 10%CH group: incorporation of 10% chitosan; 10%ND group: incorporation of 10% of nanodiamond; 5%CH-5%ND group: incorporation of 5% chitosan and 5% nanodiamond (n=14). Analyses of color stability, surface roughness, fluorescence intensity, microhardness, morphology, and chemical composition were investigated. Additionally, water sorption, hygroscopic expansion, contact angle, surface free energy, and total free energy of interaction were also assessed. After the initial readings, the samples were individually stored in red wine solution for 28 days. Data were subjected to ANOVA followed by Tukey´s test (α=.05). Aging in wine solution altered the optical, mechanical, and surface properties of glass ionomer cement regardless of the incorporation of the compound (P<.05). 10% chitosan-incorporated glass ionomer cement promoted higher color alteration, surface roughness, and water sorption after aging (P<.05). 10% nanodiamond-incorporated glass ionomer cement showed higher microhardness compared to the other groups before aging (P<.05), however there were no differences among them after aging (P>.05). In general, no differences between the 5% chitosan- and 5% nanodiamond-incorporated glass ionomer cement and control groups were noted on the evaluated analyses (P>.05). Thus, the incorporation of 5% chitosan and 5% nanodiamond is a satisfactory alternative for maintain the surface, optical, and mechanical properties of the glass ionomer cement.","PeriodicalId":101363,"journal":{"name":"Brazilian dental journal","volume":"36 ","pages":"e246215"},"PeriodicalIF":0.0,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11996155/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144065558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

According to the manufacturer, CIMMO DTA bioceramic restorative cement is a biological bioceramic cement and was introduced recently at a low cost compared to other bioceramic materials. However, no studies evaluated the effect of CIMMO DTA on human dental pulp cells (HDPC) activated with lipopolysaccharide (LPS). Therefore, this study aimed to evaluate the cytotoxicity and the osteo/odontogenic differentiation potential in HDPC activated with LPS exposed to CIMMO DTA compared to Hydro-C. HDPC activated or not with LPS were cultured, plated, and exposed to different dilutions of CIMMO DTA and Hydro-C extracts. At 24h, 48h, and 72h, the cells were subjected to the MTT assay. The osteo/odontogenic mineralization potential of cells was evaluated through the Alizarin red S staining assay at a 21-day time point. Statistical analysis was performed using a two-way analysis of variance (ANOVA) followed by Tukey's post-test (p<0.05). In general, the tested materials unaffected the metabolic activity and viability of cells in all dilutions evaluated. The CIMMO DTA reduced the osteo/odontogenic differentiation potential of the HDPC according to qualitative and quantitative results at dilutions of 1:8. Therefore, the results of the present study suggested that CIMMO DTA presents limited bioactive potential on HDPC in vitro.","PeriodicalId":101363,"journal":{"name":"Brazilian dental journal","volume":"36 ","pages":"e246402"},"PeriodicalIF":0.0,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11996156/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144034483","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Linear measurements, surface area, and volumetric measurements were conducted on a total of 140 CBCT volumes (100 for evaluation and 40 for validation) from a Brazilian population, with an equal distribution of sexes, aged between 18 and 50. Statistical analysis involved the Kolmogorov-Smirnov test, unpaired t-test with Welch correction, Pearson's correlation test, logistic regression using the Backward Stepwise method, sieve test, Kappa test, intraclass correlation coefficient, and statistical power calculation (α=0.05). The three teeth showed sexual dimorphism, with measurements from males being statistically larger. Notably, only the formulas for the lower canine met the Mohan and Daubert admissibility criteria. The formula for assessing a sound root used included the mesiodistal diameter, axial cross-section volume, and two-thirds of the coronal cross-section volume. For evaluating reduced root length, the formula incorporated the mesiodistal diameter and axial cross-section volume. The accuracy of the lower canine formulas for sound and reduced root length were 89% and 87%, respectively. After validation, both formulas achieved an accuracy of 85%. In conclusion, the models combining measurements from the lower canine can be applied as a complementary method for sex estimation.","PeriodicalId":101363,"journal":{"name":"Brazilian dental journal","volume":"36 ","pages":"e246063"},"PeriodicalIF":0.0,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11981591/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143805231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the first phase (X-ray group), the radiographic images were evaluated without clinical information; in the second phase (X-ray/CARS group), the radiographic images were assessed in conjunction with the CARS score (Caries Associated with Restorations or Sealants) and lesion activity. A radiographic classification system for carious lesions around restorations was adapted to classify the bitewing radiographs included in this study. Evaluations were conducted in consensus by a panel of specialists, focusing on the detection of caries around restorations and subsequent treatment decisions. A chi-squared test was used to compare treatment decisions between the groups, and Cohen's kappa coefficient was employed to assess the agreement of scores. The results showed a significant difference in the distribution of decisions regarding the need for restorative intervention between the groups (p < 0.001), with the X-ray/CARS group leading to more decisions favoring restorative intervention.
