AI Article Synopsis
- The study aimed to assess how effective a stannous-containing sodium fluoride toothpaste is at preventing cavities compared to other toothpaste controls.
- In vitro methods included examining fluoride uptake, remineralization effects from pH cycling, and changes in enamel hardness.
- Results showed that the stannous-containing toothpaste had similar fluoride uptake and remineralization effects to other fluoride toothpaste, but it significantly improved surface microhardness compared to both control products.
Article Abstract
Purpose: To evaluate the anticaries potential of a stabilized stannous-containing sodium fluoride dentifrice relative to appropriate control products.
Methods: A series of in vitro studies was conducted using the following standard anticaries efficacy measures: (1) fluoride uptake; (2) pH cycling remineralization/inhibition of demineralization; and (3) surface microhardness. In each study, the stannous-containing sodium fluoride test dentifrice (1450 ppm F) was compared to a negative control dentifrice (0 ppm F) and a positive control fluoride dentifrice (either 1100 ppm F or 1450 ppm F).
Results: Fluoride uptake: The mean fluoride uptake from both the test dentifrice and the positive control dentifrice was significantly greater than the negative control. There was no statistically significant difference between the two fluoride dentifrices, although the test dentifrice was directionally higher. pH cycling: The remineralization measured with the test dentifrice was directionally higher though not significantly different from the positive control dentifrice. Remineralization by both fluoride-containing dentifrices was significantly greater versus the negative control. Surface microhardness: The percent increase in surface microhardness measured on enamel surfaces after treatments with the test dentifrice was found to be significantly higher than that measured for the positive control and the negative control.

Printed versus heat-polymerized resin for occlusal devices: Evaluation of physical and mechanical properties after brushing and microbial adhesion.

Department of Dental Materials and Prosthesis, Ribeirão Preto Dental School, University of São Paulo (USP), Ribeirão Preto, Brazil.
Purpose: To evaluate the physical and mechanical properties after brushing and microbial adhesion of printed resins (PRs) and heat-polymerized resins (HRs) for occlusal devices (ODs).
Materials And Methods: Knoop microhardness and roughness were evaluated in three measurements before and after brushing with detergent or dentifrice. Flexural strength and modulus of elasticity were assessed by 3-point bending, and the adhesion of Candida albicans and Streptococcus mutans was evaluated by colony-forming units per milliliter (CFU/mL) and metabolic activity using the XTT assay only without brushing.
Polymer-Based Toothpastes and Their Ability in Control Tooth Extrinsic Stain.

Objectives: To synthesize experimental toothpastes (ETs) containing four different polymers (sodium linear polyphosphate [LPP]; chitosan [CHI]; sodium hexametaphosphate [HMP]; and sodium pyrophosphate [PP]) and test their ability in preventing and removing tooth extrinsic stain.
Methods: The tooth specimens were randomly assigned into six groups (n = 10): control (artificial saliva), regular toothpaste (RT-no whitening claim), ET 5% LPP, ET 0.5% CHI, ET 5% HMP, and ET 5% PP.
Remineralisation of enamel erosive lesions by daily-use fluoride treatments: network meta-analysis of an in situ study set.

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.

Background: The aim of this study was to investigate the effects of different types of bleaching methods and repolishing on the whiteness index and staining susceptibility of additive and subtractive production resin-based materials and direct composite resins.
Methods: In this study, a total of 96 samples (8*8*2m) were prepared using a nanohybrid composite resin (Neo Spectra-ST (NS)), a subtractive-manufactured nanoceramic resin (Cerasmart270 (CS)), and an additive-manufactured permanent resin (Saremco print Crowntec (CT)). The samples were randomly divided into four treatment groups: control (distilled water, 14 days), in-office bleaching (Opalescence Boost-40% HP, 3*20min), at-home bleaching (Opalescence PF-16% CP, 6 h, 14 days), and toothpaste group (Opalescence Whitening, 2*5min, 14 days) (n:8).
Effects of different toothpastes against erosive tooth wear of enamel and dentine in vitro.

Faculty of Dentistry, Department of Restorative Dentistry, Ondokuz Mayıs University, Samsun, Turkey.
Background: The increase in the prevalence of erosion lesions worldwide has led researchers to develop effective toothpastes with different ingredients to prevent erosion that can protect the tooth surface against acid attacks. There remains a lack of consensus in the literature regarding which toothpaste formulation exhibits the most effective preventive action against erosive tooth wear, highlighting the necessity for further investigation in this field. This study aimed to evaluate the preventive effect of brushing with toothpastes with different ingredients on enamel and dentine erosion.
