The aim of this study was to investigate the cytocompatibility and mineralization potential of two premixed hydraulic endodontic sealers compared with an epoxy resin-based root canal sealer. The cellular responses and mineralization capacity were studied in human periodontal ligament stem cells (hPDLSCs) that were exposed to premixed hydraulic sealers, Bio-C Sealer (Angelus, Londrína, PR, Brazil), TotalFill BC Sealer (FKG Dentaire SA, La-Chaux-de-fonds, Switzerland) and an epoxy resin-based material, AH Plus (Dentsply De Trey, Konstanz, Germany). Non-exposed cultures served as the control. The endodontic sealers were assessed using scanning electron microscopy (SEM) and energy dispersive X-ray microanalysis (EDX). Statistical analyses were done using Analisis of Variance (ANOVA), with Bonferroni adjusted pairwise comparison (p = 0.05). AH Plus reduced cell viability and cell migration, whereas increased cell viability and cell migration were observed in the Bio-C Sealer and the TotalFill BC Sealer (p < 0.05). The lowest cell attachment and spreading were observed for all concentrations of AH Plus, whereas the highest were observed for TotalFill BC Sealer. At the end of 21 days, only the Bio-C Sealer and the TotalFill BC Sealer supported matrix mineralization (p < 0.05). Additionally, SEM-EDX revealed high content of calcium, oxygen, and silicon in the Bio-C Sealer and the TotalFill BC Sealer. Based on the results from this study, Bio-C Sealer and TotalFill BC Sealer demonstrated better cytocompatibility in terms of cell viability, migration, cell morphology, cell attachment, and mineralization capacity than AH Plus.

Background: The period of pregnancy is characterized by a multitude of diverse changes that exert a notable impact on the oral cavity of women. During this gestational phase, patients necessitate tailored oral care and specific recommendations to preempt and address potential oral diseases. This systematic review aimed to perform a detailed analysis of the research studies that focused on the oral manifestations observed in pregnant women. Methods: A meticulous search was conducted in the databases Medline, Scopus, and Scielo by employing the following search terms: ((pregnant OR pregnancy)) AND ((“oral manifestation*”) OR (“oral health”)). Articles that were published between 2013 and 2023 and written in English or Spanish and studies that scrutinized oral manifestations in pregnant women and included a diagnosis conducted by a qualified dentist were selected; we excluded articles published before 2013, articles that could not be accessed in full text, studies whose patients were not pregnant women at the time of the study, studies where patients were selected because they had a specific disease, studies where the clinical examination was not performed by a dentist, and articles written in languages other than English or Spanish. Subsequently, the risk of bias in the chosen articles was assessed in accordance with the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) scale. Results: A total of 20 studies were included in the analysis, following the exclusion and inclusion criteria. These studies were categorized as cross-sectional, cohort, longitudinal, or case–control. Various oral manifestations in pregnant women were examined, with five studies comparing these manifestations with those observed in nonpregnant women. Conclusions: The most prevalent oral manifestations associated with pregnancy encompass dental caries, periodontitis, gingivitis, pyogenic granuloma, and candidiasis. Nonetheless, less common lesions may also emerge during the course of pregnancy.

This study aimed to analyze the biological effects of three new bioactive materials on cell survival, migration, morphology, and attachment in vitro. ACTIVA Kids BioACTIVE Restorative (Pulpdent, Watertown, MA, USA) (Activa), Ionolux (Voco, Cuxhaven, Germany), and Riva Light Cure UV (SDI, Bayswater, Australia) (Riva) were handled and conditioned with a serum-free culture medium. Stem cells from human dental pulp (hDPSCs) were exposed to material extracts, and metabolic activity, cell migration, and cell morphology were evaluated. Cell adhesion to the different materials was analyzed by scanning electron microscopy (SEM). The chemical composition of the materials was evaluated by energy-dispersive X-ray (EDX). One-way analysis of variance followed by a Tukey test was performed (p < 0.05). Ionolux promoted a drastic reduction in metabolic activity and wound closure compared to the control (p < 0.05), whereas Activa induced adequate metabolic activity and cell migration. Moreover, SEM and immunofluorescence analysis showed abundant cells exposed to Activa. The materials showed different surface morphologies, and EDX spectra exhibited different peaks of C, O, Si, S, Ca, and F ions in glass ionomer cements. The results showed that Activa induced cell migration, cell attachment, and cell viability to a greater extent than Riva and Ionolux.

The purpose is to analyze the medical characteristics of children with special health care needs (CSHCN) recommended for dental treatment under general anesthesia (GA), postoperative complications, and dental treatment outcomes under the regulation of the Spanish Dental Care Program (PADI). 111 clinical records were selected. The study population was divided into three age groups. The quantitative data was specified as the mean ± SD. For the qualitative variables, the Chi-Square test was used. One-way ANOVA and Bonferroni tests were used to examine the effect of the “age group” and the number of treatment procedures. A total of 1473 treatment procedures were performed, of which 110 (7.5%) were cleanings, 898 (61%) were restorative procedures, 332 (21.7%) were extractions, 22 (1.6%) were endodontic treatments, 62 (4.2%) were pulpotomies, and 59 (4%) were stainless steel crowns. Regarding the mean number of incisor root canal treatments (RCT), age group 3 received a significantly higher mean number of incisor RCTs than age group 1 (p = 0.02). Age group 1 received a higher average of pulpotomies and stainless-steel crowns (p = 0.00) compared to groups 2 and 3. GA is a safe procedure for the dental treatment of CSHCN, with minimal postoperative complications, which should be included among dental public programs.

Bioceramic materials possess desirable biological properties, highlighting their non-reactivity and osteoconductivity. Their use has been extended in vital pulp treatment. The purpose of this study was to evaluate and compare the effects of beta-tricalcium phosphate (β-TCP), hydroxyapatite (HA), and collagen (C) scaffold with mineral trioxide aggregate (MTA) on the vital pulp of rat molars. Thirty-two molars of Sprague–Dawley rats underwent direct pulp capping with β-TCP/HA/C (n = 16) and MTA (n = 16). After 30 days, the following parameters were evaluated in the tested samples: the degree of pulp inflammation and pulp vitality, the presence of reparative dentin, the homogeneity of the odontoblastic layer, and the presence of pulp fibrosis. No statistically significant differences were observed between HA/β-TCP/C and MTA in terms of the degree of inflammation (p = 0.124). Significant differences were found in reparative dentin formation between the treatment groups (p = 0.0005). Dentin bridge formation was observed in the MTA-treated group. The local action of HA/β-TCP/C is similar to that of MTA when used as an agent for pulp vital treatment in terms of absence of inflammation and maintenance of pulp vitality, although there are significant differences between both materials regarding the formation of dentin bridges.
