AI Article Synopsis
Article Abstract
Objective: To analyze the effects of various fluoride agents on metallic orthodontic materials.
Design: PubMed, Google Scholar, and Embase were searched using keyword combinations such as fluoride mouthwash and orthodontic appliance and corrosion, fluoride and fixed appliance, and metal degradation.
Results: Of 315 articles, 20 were selected for inclusion in the review. All types of fluoride agents, especially the acidulated form of fluoride, seemed to influence the corrosion of orthodontic metallic appliances.
Conclusion: Since most of the studies reported suggest that fluoride ions are capable of causing corrosion of metallic orthodontic appliances, attention should be paid while prescribing fluoride agents for orthodontic patients. The degree of corrosion seems to be directly correlated with the acidity of the medium and the concentration of fluoride ions. Co-Cr brackets are resistant to corrosion by fluoride while stainless steel and Ti brackets are susceptible.
Clinical Significance: It allows making the right choice while choosing the orthodontic brackets in relation to their susceptibility to corrosion by fluoride ions.

Home-use agents in the treatment of dentin hypersensitivity: clinical effectiveness evaluation with different measurement methods.
Clin Oral Investig
January 2025
Faculty of Dentistry, Department of Restorative Dentistry, Çanakkale Onsekiz Mart University, Çanakkale, 17100, Turkey.
Objectives: This study aimed to evaluate the effectiveness of home-use desensitizing agents over an 8-week period by comparing them using different measurement methods.
Methods: A randomized, controlled clinical trial was conducted with 180 individuals aged between 18 and 70 who clinically diagnosed dentin hypersensitivity (DH) in two or more non-adjacent teeth. Subjects who met the inclusion criteria (n = 164) were randomly allocated into five test groups-using Casein phosphopeptide-amorphous calcium phosphate (CPP-ACP), Arginine, Novamin, Propolis, and Potassium nitrate-and a control group using standard fluoride toothpaste.
Synthesis of zirconium-based metal-organic framework/gelatin aerogel for removing phosphate and fluoride from aqueous solutions.

This study describes the preparation of novel hybrid aerogels derived from gelatin (Gel), incorporating Br-functionalized zirconium-based metal-organic framework (UiO-66-Br; MOF) as modifying agent to effectively eliminate phosphate and fluoride ions from aqueous environments. The adsorption performance of MOF decorated Gel (Gel-xMOF) hybrid aerogels was investigated under different conditions, including agitation time, adsorbent dosage, solution pH, initial phosphate and fluoride concentrations, coexisting ions, and temperature. The functional groups of the gelatin network, coupled with UiO-66-Br, enhanced the adsorption performance of phosphate and fluoride ions from aqueous solutions.

Article Synopsis
- The study investigates the effectiveness and safety of dentifrices containing Nano silver fluoride (NSF) against the bacteria Streptococcus mutans, which causes tooth decay.
- Researchers synthesized NSF particles and created dentifrices with varying concentrations of NSF, assessing their antimicrobial properties using an agar diffusion method and cytotoxicity on mouse macrophage cells.
- Results showed that NSF dentifrices inhibited bacterial growth effectively while also evaluating their impact on cell viability to ensure safety for use in oral health products.

Objectives: Comparative evaluation of indirect pulp therapy (IPT) with silver diamine fluoride (SDF), Type VII glass ionomer cement (GIC), and calcium hydroxide (Ca(OH)2) in young permanent molars.
Materials And Methods: This was randomized controlled trial, in which 45 children with 60 young permanent first molars were allocated as; Group A: IPT with SDF, Group B: Type VII GIC, and Group C: Ca(OH)2. Clinical and radiographic evaluation and comparison was done at baseline, 3, 6, 12 months.
Realizing Antithermal Quenching Red Emission in Mn-Activated RbNaVF for Optical Thermometry Sensor Application.
Luminescence
January 2025
Faculty of Materials Science and Chemistry, China University of Geosciences, Wuhan, China.
Currently, the development of red Mn-activated fluoride luminescent materials attracts a lot of attention in optical thermometry sensors, solid lighting, display, and plant growth areas. Nevertheless, the thermal stability of Mn-activated fluoride luminescent materials is still a crucial issue. Herein, a new red RbNaVF:Mn luminescent material with outstanding thermal stability was successfully synthesized through the facial coprecipitation method.
