Purpose: Although the effectiveness of fluoride dentifrice in remineralizing enamel caries has been established, the optimum fluoride concentration for remineralization root caries has not been defined. The aim of this study was to assess and compare the effect of 1.1g/L, 1.45g/L and 5g/L fluoride dentifrices in remineralization of artificial root caries.
Methods: Sound human tooth fragments obtained from the cervical portion of root were stored in a demineralization solution for 96h at 37 degrees centigrade to induce artificial root caries lesions. The fragments were then randomly divided into four treatment groups including 1.1g/L, 1.45g/L, 5g/L fluoride dentifrice group and non-fluoride dentifrice control group. The demineralized samples were pH-cycled through treatment solutions, acidic buffer and neutral buffer for 8 days at 6 cycles per day. The samples were evaluated using electrical caries monitor(ECM), polarized light microscopy (PLM) and confocal laser scanning microscopy (CLSM). The data was analyzed using ANOVA with SPSS13.0 software package.
Results: Variations of LgECM, total fluorescence and average fluorescence from CLSM after remineralization in fluoride dentifrice groups were significantly higher than those in the control group(P<0.05) Variations of LgECM, total fluorescence and average fluorescence from CLSM after remineralization in the 5g/L fluoride dentifrice group were significantly higher than those in the 1.1g/L and 1.45g/L fluoride dentifrice groups(P<0.05). PLM observation showed that a banding or deposit of mineral appeared within the lesions of specimens in the fluoride dentifrice groups. A wider mineral band was seen in the 5g/L fluoride dentifrice group than in the 1.1g/L and 1.45g/L fluoride dentifrice groups.
Conclusions: Fluoride dentifrice is effective in remineralizing artificial root caries and 5g/L fluoride dentifrice has better effect than 1.1g/L and 1.45g/L fluoride dentifrices.

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.
A Randomized Clinical Study Investigating the Stain Removal Efficacy of Two Experimental Dentifrices.

All Sum Research Center Ltd., Mississauga, Ontario, Canada.
Objective: This study aims to evaluate extrinsic tooth stain removal and whitening efficacy of two experimental dentifrices containing (i) 5% sodium tripolyphosphate (STP)/1% micronized alumina or (ii) 5% STP/1% micronized alumina with abrasive silica (ED2) compared to a regular fluoride dentifrice (RFD) following 8 weeks of use.
Materials And Methods: This was a single-center, randomized, controlled, blind, three-arm, stratified, parallel-group study. Eligible participants underwent clinical assessment of stain on the facial/lingual surfaces of maxillary and mandibular teeth using the modified Lobene stain index (MLSI), and shade of the facial surfaces of the central and lateral maxillary incisors using the VITA Bleachedguide 3D-Master (VITA) shade guide.

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.
Effect of different protocols in preventing demineralization in irradiated human enamel, in vitro study.

Department of Operative Dentistry, Faculty of Dentistry, Chulalongkorn University, Bangkok, Thailand.
Background: This in vitro study evaluated the efficacy of professional and home-use fluoride regimens for protecting irradiated enamel, undergoing pH cycling resembling xerostomia.
Methods: Sixty human premolar teeth were irradiated with a total dose of 70 Gy and subsequently sectioned into 3 × 3 cm enamel slabs. These slabs were randomly distributed into five groups (n = 12 per group): professional-use groups received fluoride varnish either weekly (FV1) or biweekly (FV2); home-use groups applied 5000 ppm (FT5) or 1450 ppm (FT) fluoride toothpaste; and a control group (control) received no treatment.

This study aimed to evaluate the effectiveness of bioactive toothpastes in remineralizing eroded enamel surfaces in vitro. Bovine enamel blocks (n = 48) were obtained and classified into untreated, demineralized, and treated areas. Specimens were randomly classified into six groups (n = 8 each): fluoride-free toothpaste (NCT), Colgate Total 12 (PCT), Sensodyne Repair and Protect (SRP), Sensodyne Pronamel (SPE), Regenerador + Sensitive (RGS), and RGS/calcium booster (RCB).
