Enhancement of a Modified Nano Restorative Mixture in Relation to Antibacterial Activity, MTT, and Spectroscopic Properties Maitha Sameer Kadhim, Shammaa Anees Alansari, Maysaa Sameer Kadhim, Hayder Hamed Abed Al Rafidain Journal of Medical Sciences, 2025 Background: Evidence-based medical studies support the effectiveness of silver diamine fluoride (SDF) in removing or even suppressing caries lesions, considering it a non-invasive treatment modality in dental health care. Objective: Investigate the impact of zinc nanoparticles on the antibacterial activity, cytotoxicity, and optical properties of modified SDF. Methods: Mix zinc nanoparticles with SDF filling material in three variable ratios to create four experimental groups. The microbial sensitivity test for these groups was performed by measuring the diameters of the inhibition zones on the Muller-Hinton agar medium. Cytotoxicity assessment using the MTT test, by ISO-10993-5 guidelines, examined the cellular viability. A spectrophotometer analysis was used to evaluate the absorption in wavelengths ranging from 190 to 780 nm. Results: Revealed a dose-dependent efficacy of zinc nanoparticles with a better antibacterial effect than SDF alone; the cell bioavailability of zinc experimental groups remains within the acceptable measurements. Spectrophotometry was not correlated with adding zinc nanoparticles, especially within the visible light range. Conclusions: Mixtures of zinc nanoparticles with SDF were found to have more effective activity against the three human pathogens. At the same time, their cytotoxic pictures are acceptable but without a remarkable color change and aesthetic enhancement.
Evaluating the Citotoxicity and Antibacterial Activity of Nano Zinc-Glyde Mixture for Intracanal Irrigation Shammaa Anees Sahib AlAnsari, Maitha Sameer Kadhim, Hayder Hamed Abed Dentistry 3000, 2025 Objective: In this research, we evaluated the antibacterial efficiency and cytotoxicity of Glyde including its Zinc NPs preparations in three different ratios comparing them with the conventional Glyde. Material and Methods: Antibacterial efficiency was evaluated using inhibition zone method against three common gram-positive pathogens Enterococcus faecali, Lactobacillus and Streptococcus. Three different irrigant preparations were evaluated, GI: Glyde gel alone as a control group, GII: experimental gel (3% Zinc NPs-Glyde), GIII: (4% Zinc NPCs-Glyde gel), GIV: (5% Zinc NPCs-Glyde gel). We evaluated the cytotoxicity by the MTT test. assessing the cells’ viability as soon as possible after 24h, 48h, and 72h. After a color change assessment, spectrophotometric analysis with wavelength ranged from 190-780 nm was performed. The spectrum analysis was performed for diluted mixtures in solvent. Data were plotted and recorded for each wavelength. Kruskal–Wallis (p < 0.05) and post-hoc Bonferroni pairwise (p < 0.05) were used for statistical analysis. Results: All the groups a reduction of the three types of bacteria (p > 0.05) was seen, with inhibition zone increasing with increasing addition of zinc NPs up to 5%. For cytotoxicity, it seems that cell bioavailability remained for 24h, 48h, and declined at 72h. Data were not correlated with addition of zinc nano particles, especially within the visible light range. Conclusion: The addition of zinc nanoparticles has acceptable antibacterial properties and cytotoxic features, and Glyde gel may be used for root canal disinfection without remarkable color change.
Effect of the Rs2923234 and Rs1049112 Single Nucleotide Polymorphisms of Salivary Acidic Proline-rich Protein on Dental Caries in Young Children: An Analytical Cross-sectional Molecular Study Maitha Sameer Kadhim, AhlamTaha Mohammed Dental Hypotheses, 2023 Introduction: We aimed to use polymerase chain reaction (PCR) on genomic deoxyribonucleic acid (DNA) to detect the Db allele and the rs2923234 and rs1049112 single nucleotide polymorphisms (SNPs) of the salivary acidic proline-rich proteins (PRPs) to determine their relationship with dental caries in young children. Methods: DNA was extracted from saliva samples of preschool children aged 3 to 5 years. PCR primers designed around exon 3 of the PRH1 locus yielded a 416-base product representing Db for gel electrophoresis and a 519-base product representing the rs2923234 and rs1049112 SNPs for Sanger sequencing. The data were analyzed using a logistic regression model and a multilayer perceptron artificial neural network. Results: Forty children with severe caries and 40 caries-free children completed the study. The frequency of the Db gene was 16.3% in the entire study group. The rs2923234 SNP was a marginally significant (P = 0.053) predictor for the dependent variable (caries-free or severe caries). However, the rs1049112 (P = 0.407) and the Db allele (P = 0.442) were not significant predictors. Conclusion: The rs29232334 SNP could be considered a potential genetic predictor for caries susceptibility.
