Objectives: Daily-use fluoride products are first-line protection against enamel wear from dietary-acid exposure (DAE). This study aimed to understand effects of fluoride concentration, fluoride salt, product form and ingredients in daily-use products on remineralisation and demineralisation, via network meta-analysis (NMA) of 14 studies using one well-established in-situ model. Remineralisation (surface-microhardness recovery, SHMR) after treatment, and protection against subsequent demineralisation (acid-resistance ratio, ARR) were measured.

Introduction: Among the wide variety of commercially oral hygiene products, activated charcoal-based toothpastes have irrupted the market, claiming multiple benefits. Although most are fluoride free, others incorporate fluoride into their formulations, yet the chemical availability and stability of fluoride in these products remain unclear. Our study aimed to assess the chemical availability and stability of fluoride in commercially fluoridated toothpastes formulated with activated charcoal.

Background: Decreased salivary secretion is not only a risk factor for carious lesions in Sjögren's disease (SD) but also an indicator of deterioration of teeth with every restorative replacement. This study determined the longevity of direct dental restorations placed in patients with SD using matched electronic dental record (EDR) and electronic health record (EHR) data.

Methods: We conducted a retrospective cohort study using EDR and EHR data of Indiana University School of Dentistry patients who have a SD diagnosis in their EHR.

Article Synopsis
  • Dental caries, a prevalent disease caused by oral biofilms, persists despite fluoride use, but iron oxide nanoparticles (ferumoxytol) can degrade these biofilms with hydrogen peroxide.
  • When combined with stannous fluoride, ferumoxytol significantly enhances the inhibition of biofilm growth and enamel damage compared to using either treatment alone.
  • This combination is effective in controlling dental caries in live subjects at much lower concentrations and shows no negative effects on surrounding tissues or the oral microbiome, highlighting its potential as a safe and efficient treatment for oral health.

Article Synopsis
  • Dental caries, a common disease caused by oral biofilms, affects nearly half of the global population despite the use of fluoride, although a new FDA-approved iron oxide nanozyme (ferumoxytol) shows promise in disrupting these biofilms.
  • Combining ferumoxytol with stannous fluoride significantly enhances their effectiveness in preventing both biofilm accumulation and enamel damage, outperforming either treatment alone.
  • The synergy between these two agents not only stabilizes the stannous fluoride but also improves its catalytic activity, demonstrating a novel method to combat dental caries without adverse effects on oral health or microbiome diversity.

Article Synopsis
  • The study looked at how different materials used to fix cavities in teeth can affect treatment success in kids' (primary) and adult (permanent) teeth.
  • Researchers reviewed 38 different studies that tested materials like amalgam and resin composites on various types of cavities.
  • They found that while some materials worked better than others, the differences weren't very big, meaning most of them are pretty similar in effectiveness.

Severe tooth decay has been associated with iron deficiency anemia that disproportionally burdens susceptible populations. Current modalities are insufficient in severe cases where pathogenic dental biofilms rapidly accumulate, requiring new antibiofilm approaches. Here, we show that ferumoxytol, a Food and Drug Administration-approved nanoparticle formulation for treating iron deficiency, exerts an alternative therapeutic activity via the catalytic activation of hydrogen peroxide, which targets bacterial pathogens in biofilms and suppresses tooth enamel decay in an intraoral human disease model.

Article Synopsis
  • The study evaluated the effectiveness of cross-polarization optical coherence tomography (CP-OCT) in monitoring erosive tooth wear (ETW) across different levels of severity with 20 participants over a 14-day period.
  • Participants were exposed to severe, moderate, and non-erosive conditions using citric acid solutions, and enamel thickness was assessed using CP-OCT and micro-computed tomography (μ-CT).
  • Results indicated that CP-OCT effectively detected increased enamel loss over time and distinguished between varying severities of ETW, suggesting its potential use for clinical monitoring of tooth erosion.

Objectives: To provide consensus recommendations on how to intervene in the caries process in adults, specifically proximal and secondary carious lesions.

Methods: Based on two systematic reviews, a consensus conference and followed by an e-Delphi consensus process were held with EFCD/ORCA/DGZ delegates.

Results: Managing an individual's caries risk using non-invasive means (oral hygiene measures including flossing/interdental brushes, fluoride application) is recommended, as both proximal and secondary carious lesions may be prevented or their activity reduced.

Toothpastes are the most universally accepted form of fluoride delivery for caries prevention. To provide anti-caries benefits, they must be able to release fluoride during the time of tooth brushing or post brushing into the oral cavity. However, there is no standard accepted procedure to measure how much fluoride in a toothpaste may be (bio) available for release.
