Objective: This proof-of-concept sequence of in vivo/in vitro studies aimed to unveil the role of acquired enamel pellicle (AEP) engineering with statherin-derived peptide (StN15) on the AEP protein profile, enamel biofilm microbiome in vivo and on enamel demineralization in vitro.
Design: In vivo studies, 10 volunteers, in 2 independent experiments (2 days each), rinsed (10 mL,1 min) with: deionized water (negative control) or 1.88 × 10 M StN15.
An animal model was applied to develop erosive tooth wear (ETW) and to evaluate the efficacy and safety of titanium tetrafluoride (TiF) in preventing ETW. Forty-eight male Wistar rats were divided into three groups (n = 16): TiF (2.45% F), NaF (2.

Bovine root samples were divided into: irradiated (70 Gy) dentin or not; the type of biofilm (from irradiated patient-experimental or non-irradiated patient-control) and the type of artificial saliva (for the condition irradiated dentin/biofilm from irradiated patient): Control Artificial Saliva (inorganic); Control Saliva + 1 mg/ml hemoglobin; Control Saliva +0.1 mg/ml cystatin; Control Saliva + hemoglobin + cystatin; Bioextra (positive control) and deionized water (DiW, negative control) (n = 12/group).

Design: After prophylaxis, 10 volunteers rinsed (10 mL, 1 min) with the following solutions: 1) deionized water (HO- negative control or 2) 0.1 mg/mL CaneCPI-5.
This study evaluated the protective effect of TiF and chitosan toothpaste on erosive tooth wear (ETW) in vitro. Enamel and dentin samples were randomly assigned to toothpastes (n = 12): (G1) TiF (1400 ppm F), (G2) 0.5% chitosan (75% deacetylation, 500 mPas), (G3) TiF (1400 ppm F) plus 0.

Materials And Methods: In five crossover phases, after prophylaxis, 10 volunteers in 5 consecutive days, rinsed (10 mL, 1 min) with the following solutions: deionized water (HO- negative control- 1), 0.1 mg/mL CaneCPI-5 (2), 1.
Objective: This study compared the effect of commercial and pure sweetener containing stevia to that of aspartame, to sucrose and xylitol on the development of dental caries.
Methods: 228 bovine enamel and root dentin were exposed to microcosm biofilm model using human saliva. From the 2 to the 5 day, the samples were exposed daily to McBain saliva supplemented with 0.
Objective: This study evaluated the effect of experimental solutions containing TiF/NaF and chitosan on bacterial species of microcosm biofilm and on dentin demineralization.
Design: Microcosm biofilm was produced from human saliva mixed with McBain medium (0.2% sucrose) on bovine dentin for 5 days, under 5% CO and 37 °C.
Objectives: To evaluate the effect of experimental solutions containing TiF/NaF and chitosan on bacterial species and on enamel caries prevention.
Methods: Microcosm biofilm was produced from human saliva mixed with McBain saliva (0.2% sucrose) on bovine enamel for five days, under 5% CO and 37 °C.
This in vitro study evaluated the protective effect of titanium tetrafluoride (TiF) varnish and silver diamine fluoride (SDF) solution on the radiation-induced dentin caries. Bovine root dentin samples were irradiated (70 Gy) and treated as follows: (6 h): 4% TiF varnish; 5.42% NaF varnish; 30% SDF solution; placebo varnish; or untreated (negative control).

Objective: The aim of this in vitro study was to evaluate the protective effect against enamel erosion of experimental solutions containing TiF/NaF and Chitosan compared to a commercial SnCl/NaF/AmF solution.
Design: Bovine enamel samples were divided (n = 15/group) into: (1) commercial solution SnCl/NaF/AmF (500 ppm F, positive control); (2) NaF/TiF (490 ppm F); (3) similar to 2 plus 0.5 % chitosan (Ch) (500 mPas), (4) similar to 2 plus 0.
Objective: This study evaluated the antibiofilm and anti-caries effects of an experimental mouth rinse containing aqueous extract of Matricaria chamomilla L.
Methods: Microcosm biofilm was produced on bovine enamel, from pooled human saliva mixed with McBain saliva, under 0.2 % sucrose exposure, for 5 days.
Objectives: This study evaluated the erosive tooth wear promoted by commercial whitening toothpastes on eroded dentin in vitro.
Design: Ninety bovine roots were embedded, polished and subjected to the baseline profile analysis. The samples were protected in 2/3 of the dentin surface and were randomly assigned to 6 groups (n = 15/group): Oral-B 3D White; Close-up Diamond Attraction Power White; Sorriso Xtreme White 4D; Colgate Luminous White; Crest and erosion only.
Objective: This study compared the effect of an experimental NaF/TiF mouth rinse with a commercial tin/F mouth rinse on the prevention of tooth wear in situ.
Methods: Fifteen subjects took part in this crossover and double-blind study, in which they wore a palatal appliance with 8 bovine teeth samples (4 enamel and 4 root dentine) in each of 3 phases (5 days each). Half of the samples were subjected to erosive challenges, and the other half to erosive plus abrasive challenges.

Background: Titanium tetrafluoride (TiF) has regained interest due to new formulations that have been shown to be more effective against tooth demineralization than sodium fluoride (NaF) formulations in vitro and in situ.
Objective: The aim of this study is to evaluate the effect of two types of varnishes (4% TiF and a commercial 5% NaF) on the prevention of carious lesions and the treatment of noncavitated enamel carious lesions in the permanent teeth of children living in a fluoridated area.
Methods: This randomized, controlled, parallel and single-blind clinical trial involves 63 children, 6-7 years old, living in Bauru, São Paulo, Brazil.
Purpose: To evaluate the in vitro abrasive effect of commercial whitening toothpastes on eroded bovine enamel samples in respect to erosive tooth wear.
Methods: 72 bovine crowns were embedded, polished and subjected to the baseline profile analysis. The samples were then protected in 2/3 of the enamel surface and were randomly assigned to six groups (n= 12/group): G1: Oral-B 3D White, G2: Close-up Diamond Attraction Power White, G3: Sorriso Xtreme White 4D, G4: Colgate Luminous White, G5: Crest (conventional toothpaste), G6:erosion only (control).
