Six patients enrolled at the Hospital of Rehabilitation of Craniofacial Anomalies, University of São Paulo, aging 16 to 20 years, were selected. All patients presented with white spots in both sides of the superior arch, which totalized 41 spots. The left side of the arch was submitted to remineralization by means of the conventional technique with Reminer, a commercially available product. In the right side, a modified technique was employed, with the utilization of fluoridated dentifrices every night, during 8 weeks. It was observed that successful remineralization occurred in 62% of the spots when the conventional technique was employed, whereas, when fluoridated dentifrices were utilized, there was partial remineralization in 10% of the spots. The utilization of Reminer was more effective than the utilization of fluoridated dentifrices.

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

January 2025
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.
BMC Oral Health

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.
Biomimetic and protective effects of bioactive toothpastes on eroded enamel surfaces.

Universidade Federal da Paraíba - UFPB, Health Science Center Department of Clinical and Community Dentistry, João Pessoa, PB, Brazil.
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).
