Article Abstract
Objectives: This network meta-analysis compares different desensitizing toothpastes and placebo in terms of their effects on dentine hypersensitivity (DH) at 2, 4, and 8 weeks.
Materials And Methods: A systematic electronic literature search of four databases, and a manual search, were performed to identify randomized controlled trials (RCTs) on different desensitizing toothpastes for the treatment of DH. Pair-wise and network meta-analyses were performed to analyze the desensitization effect at 2, 4, and 8 weeks. The risk of bias was assessed based on the Cochrane guidelines and funnel plots. Statistical heterogeneity, inconsistencies, and ranking probability were also evaluated.
Results: A total of 30 RCTs were included in the network meta-analysis, which included eight desensitizing toothpastes. There was no significant difference in the effect among calcium sodium phosphosilicate-containing (CSPS), potassium-containing (K) and strontium-containing (Sr) toothpastes. In addition, there was no significant difference between fluoride (F) and placebo. The desensitizing toothpaste with the highest probability of being the most effective treatment for DH was nano-hydroxyapatite (n-HA) at 2 and 4 weeks (60% and 67%, respectively), and Ar at 8 weeks (54%).
Conclusions: No significant difference was detected in desensitizing effects among CSPS, K and Sr toothpastes. In addition, there was no significant difference between F and placebo, K and placebo. Furthermore, a significant placebo effect on DH was found in this study. Moreover, n-HA toothpastes may be the best desensitizing toothpastes for treatment of DH, followed by Ar toothpaste.
Clinical Significance: Based on the results of present network meta-analysis, n-HA containing toothpastes might be a recommended desensitizing toothpastes considering the treatment of DH. PROSPERO registration number: CRD42019117710.

Effects of desensitizing and/or anti-erosive toothpastes combined with mouthrinses on enamel structure and dental pulp fibroblasts viability.
Dent Mater J

Biomaterials Lab, Dentistry School, Federal University of Pará.
This study evaluated the chemical profile of toothpastes (TPs) and mouthrinses (MRs) and their effects on tooth enamel ultrastructure, and the viability of human dental pulp fibroblasts (hDPF). Four TPs and MRs containing different remineralizing agents (arginine, potassium nitrate, pro arginine, and stannous chloride) were analyzed for pH, titratable acidity (TA), and ion concentrations (Ca, K, Na). Enamel ultrastructure was evaluated using Fourier-transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM).

Background: This study aimed to compare the efficacy of casein phosphopeptide-amorphous calcium phosphate fluoride (CPP-ACPF) and propolis-based herbal toothpaste in the treatment of dentin hypersensitivity (DH).
Materials And Methods: In this clinical trial, 20 patients (7 men and 13 women) who met the inclusion criteria were randomly divided into two groups. One group received the herbal toothpaste containing propolis (Herbex), while the other received a paste containing CPP-ACPF (GC MI-Paste Plus).

Objectives: To investigate whether a TiF varnish, a SnCl/AmF/NaF and chitosan-containing toothpaste (Elmex Opti-namel), and a fluoride-calcium-phospho-silicate-containing toothpaste (Biomin F) can reduce dentin hypersensitivity (DH) and improve oral health-related quality of life (OHRQoL) similarly to NaF varnish over 6 months.
Methods: Fifty-one patients/241 teeth were randomized into four groups. DH was measured using a 10-point visual analog scale after evaporative and tactile stimuli at baseline, immediately after application, and after 1, 3, and 6 months.

Background: Dentin hypersensitivity (DH) is common, particularly among periodontal patients. This trial evaluated magnitude of desensitizing benefit, onset of action, and complete relief of three dentifrices with distinct desensitizing technologies.
Methods: Healthy adults with DH were enrolled and randomized to one of four dentifrices in this randomized, controlled, double-blind trial: marketed potassium nitrate (KNO), marketed stannous fluoride (SnF), experimental 1.
