Article Abstract
Tooth discoloration is a common cosmetic concern, often addressed using whitening dentifrices (WDFs). This updated systematic review and meta-analysis aimed to assess the effectiveness of WDFs in decreasing tooth surface discoloration compared to regular dentifrices (RDFs). A comprehensive search of multiple electronic databases identified 14 randomized controlled trials (RCTs) meeting the inclusion criteria. The meta-analysis showed that WDFs significantly reduced both the area and intensity of stains, with 94.45% and 77.78% efficacy, respectively. Studies incorporating adjunctive chemical agents in WDFs showed enhanced stain reduction. Despite significant heterogeneity (I = 91%) among the studies, the results consistently favored WDFs over RDFs. Low publication bias was detected, and sensitivity analyses confirmed the robustness of the findings. These results endorse the utilization of WDFs for managing extrinsic tooth stains, though further research is needed to standardize methodologies and assess long-term effects.

Surface properties of direct restorations and adjacent dental tissues after saliva exposure.

Universidade Positivo, School of Health Sciences, Graduate Program in Dentistry, Curitiba, PR, Brazil.
This study assessed the effect of saliva exposure on roughness (Ra) and Vickers hardness (VHN) of two direct restorative materials, enamel, and dentin adjacent to the restorations. Enamel and dentin cavities in molars (n = 10) were restored with a) bulk-fill resin composite (Tetric N-Flow Bulk Fill, BF) with the application of a universal adhesive (Tetric N-Bond Universal) and b) alkasite restorative material (Cention N, CN) with and without the application of a universal adhesive. After 24 h (baseline), surface roughness and hardness of the restorative material and dental tissues were assessed at 100 μm from the tooth/restoration interface.

Development of dental caries is a dynamic process; yet, there is limited knowledge on microbial differences at various stages of caries at higher resolution. To investigate the shifting microbiome profiles across different caries stages, 30 children were enrolled in this study, including 15 caries-active patients and 15 caries-free individuals. Plaque samples were collected from the buccal surface of caries-free subjects, defined as confident health (CH; = 15).

Objective: It is well-established that occlusion and dental arch form are related to the morphology and function of the oral soft tissues. Oral soft tissue dynamic assessment is important for elucidating the causes of malocclusion and developing effective treatment methods. We previously developed a small mouthguard-type sensing device for measuring oral soft tissue pressure; however, its continuous measurement performance had not been thoroughly evaluated.

This 30-mo double-blind randomized clinical superiority trial aimed to assess the effectiveness of semiannual application of 38% silver diamine fluoride (SDF) solution in preventing early childhood caries in primary upper anterior teeth. The active comparator was 5% sodium fluoride varnish (FV). The primary outcome was the mean number of new carious tooth surfaces per child at the 30-mo follow-up.
