AI Article Synopsis
- The study focuses on using stem cells from human teeth (SHED) combined with a PMMA-HA biomaterial for potential bone healing applications.
- The researchers tested different concentrations of PMMA-HA scaffolds for toxicity on SHED and osteoblast cells, finding the best viability at a 20/80 ratio for both cell types.
- Results suggest that the PMMA-HA material is non-toxic to these cells, indicating its potential as a safe option for treating bone defects, though animal studies are needed for further validation.
Article Abstract
Objectives: Stem cell from human exfoliated deciduous teeth (SHED) has great potential for bone tissue engineering and cell therapy for regenerative medicine. It has been combined with biomaterials such as mixed of polymethylmethacrylate (PMMA) and hydroxyapatite (HA) as candidates for synthetic bone graft biomaterial. The aim of this study was to analyze the toxicity test of mixed PMMA-HA scaffold seeded with SHED and osteoblast .
Materials And Methods: SHED was isolated from the pulp of noncarious deciduous teeth and osteoblast cells were cultured, and exposed to PMMA-HA scaffolds with three concentration groups: 20/80, 30/70, and 40/60 for 24 hours. Cytotoxicity test was performed by MTT assay to cell viability.
Statistical Analysis: Data were analyzed using IBM SPSS Statistics 25, one-way analysis of variance followed by least significant difference test, considering the level of significance -value less than 0.05 RESULTS: The percentage of SHED's viability was best in the PMMA-HA group with concentrations of 20/80, followed by 30/70, and 40/60 with 87.03, 75.33, and 65.79%, respectively. The percentage of osteoblast cell's viability was best in the PMMA-HA group with concentrations of 20/80, followed by 30/70, and 40/60 with 123.6, 108.36, and 93.48%, respectively.
Conclusions: Mixed PMMA-HA was not toxic for the SHED and osteoblast. This characteristic is the initial requirement to be proposed as an alternative material for healing alveolar bone defects. In vivo animal research is mandatory to confirm the use of PMMA-HA on the alveolar defect model.

Dental trauma is common in all age groups, although, epidemiologically, it is more common in children with studies that indicate that 15% of preschoolers and 20-25% of school-age children experience it. These injuries, which frequently call for immediate attention, can affect the hard tissues and supporting components of the teeth, and, because dental damage in deciduous teeth occurs frequently and affects speech, nutrition, and oral development, it is particularly worrying. After searching three databases, Scopus, Web of Science (WoS), and PubMed, and removing duplicates, 3,630 articles were screened, and 12 publications were included in the qualitative analysis.

To investigate the oral health-related quality of life (OHRQoL) of young children in a randomized clinical trial (RCT) of silver diammine fluoride (SDF) and five percent sodium fluoride varnish (NaFV) to manage early childhood caries (ECC). Children younger than 72 months of age with active dentinal caries lesions (ICDAS 5 or 6) in primary teeth received two applications of 38 percent SDF and five percent NaFV as part of an RCT testing three different frequency regimes (one, four, and six months apart). The Early Childhood Oral Health Impact Scale (ECOHIS) questionnaire was completed at three study visits.

As ruminants are frequently affected by periodontal diseases, understanding their microbial communities is crucial. In this pilot study, we analyzed subgingival biofilm samples of young cattle across different states: clinically healthy (n=5), gingivitis (n=5), and periodontitis (n=5) using 16S rRNA gene sequencing and co-occurrence network analysis. The findings revealed that Proteobacteria was the predominant phylum across all conditions, with Fusobacteriota constituting 27.
