Background: To evaluate the effectiveness of an experimental toothpaste based on Juss. essential oil against a bacterial consortium associated with dental caries.
Material And Methods: The antibacterial activity of the essential oil was evaluated by the disk diffusion and microdilution tests against , and .
Objectives: This study evaluated the effects of adding silver nanoparticles on the shear bond strength, microhardness, and surface roughness of orthodontic adhesives.
Material And Methods: Fifty upper premolars were randomly allocated to five groups (n = 10). Orthodontic brackets were bonded with silver nanoparticle (AgNP)-modified adhesives (1 %, 0.
Background: Silver nanoparticles (AgNPs) are an effective antibacterial agent, and their inclusion in orthodontic adhesives has been proposed to prevent white spot lesions (WSLs). The objective of this study was to evaluate by Raman microscopy the preventive effect of an orthodontic adhesive modified with AgNPs on the formation of WSLs.
Material And Methods: AgNPs were added in four concentrations (0.
Objective: This article aims to provide an evaluation of the psychometric properties of the instruments of oral health literacy in adults.
Methods: An electronic search for instrument studies was performed in the PubMed, PubMed Central, ScienceDirect, Scopus, EMBASE, and PsycINFO databases to find articles published up to June 2021. The risk of bias of the included studies was assessed using the COSMIN (COnsensus-based Standards for the selection of health Measurement INstruments) Risk of Bias checklist for systematic review.
Background: To evaluate the effect of an orthodontic resin modified with various concentrations of silver-nanoparticles (AgNPs) on enamel color.
Material And Methods: Twenty lower premolars were collected and divided into four groups (n = 5) according to the concentration of AgNPs (0.05%, 0.
Background: To evaluate the antibacterial property of a modified orthodontic resin with different concentrations of silver-nanoparticles (AgNPs), and quantify its preventive effect on the formation of white spot lesions (WSLs).
Material And Methods: An orthodontic resin (Transbond XT) was modified with four concentrations of AgNPs (1%, 0.5%, 0.
Objective: Evaluate the height, thickness and cortical density of the palatal bone of adults with different vertical facial patterns using Cone-Beam Computed Tomography (CBCT).
Methods: This study analyzed 75 CBCTs of patients between 18 and 35 years old (45 men and 30 women). The CBCTs were classified into three groups based on their facial pattern: normodivergent, hypodivergent and hyperdivergent as determined from lateral cephalograms synthesized from the CBCTs.
Background: There are different etching gels available, which have different composition, different pH, and different viscosity, and there is little information in the literature comparing all these products.
Objective: To evaluate the mean microshear bond strength and morphological characteristics of tooth enamel by evaluating different phosphoric acids combined with a universal adhesive system.
Materials And Methods: Eighty-four enamel samples were used, which were divided according to the acid conditioning: G1: Scotchbond Etchant (3M Oral Care), G2: Ultra-Etch (Ultradent), G3: Eco-Etch (IvoclarVivadent), G4: ETCH-37 with BAC (Bisco), G5: Etching gel (Densell), G6: Condac 37 (FGM), and G7: Scotchbond Universal Adhesive (3M Oral Care) in self-etch mode.
During dental bleaching the staining potential of the surface would increase. This study aims to evaluate the staining susceptibility of one bleached composite resin after the exposure to three different beverages: Peruvian purple corn based beverage (chicha morada), green tea, and distilled water. Thirty disk-shaped specimens of one nanofill composite resin were prepared.

Bleaching was performed with 35% hydrogen peroxide gel in 40 patients who were randomly divided into placebo and nano-calcium phosphate paste groups. Bleaching efficacy (BE) was evaluated using a value-oriented Vita shade guide.

Thirty-five patients, with at least four NCCLs each, participated in this study. After samplesize calculation, 180 restorations were assigned to one of the following groups: OFL (Optibond FL), OSP (Optibond Solo Plus), XTR (Optibond XTR), and AIO (Optibond All-In-One).

Objective: The aim of this clinical study was to determine the efficacy of Uncaria tomentosa (cat's claw) against denture stomatitis (DS).
Study Design: Fifty patients with DS were randomly assigned into 3 groups to receive 2% miconazole, placebo, or 2% U tomentosa gel. DS level was recorded immediately, after 1 week of treatment, and 1 week after treatment.
A new universal simplified adhesive: 6-month clinical evaluation.
J Esthet Restor Dent
February 2013
Statement Of The Problem: Multimode adhesives, which can be used as etch-and-rinse or as self-etch adhesives, have been recently introduced without clinical data to back their use.
Purpose Of The Study: To evaluate the 6-month clinical performance of Scotchbond Universal Adhesive (SU; 3M ESPE, St. Paul, MN, USA) in noncarious cervical lesions (NCCLs) using two evaluation criteria.
Furcal perforations are significant iatrogenic complications of endodontic treatment and could lead to endodontic failure. Mineral trioxide aggregate (MTA) has been regarded as an ideal material for perforation repair, retrograde filling, pulp capping, and apexification. This case report describes a furcal perforation in a maxillary first molar, which was repaired using MTA.

Methods: 60 participants with tooth color darker than C2, without restorations in the anterior dentition and older than 18 years old, were randomly allocated into two groups to receive either IO with 35% hydrogen peroxide or AH with 16% carbamide peroxide. Color was recorded at baseline (BA); 1-week (1W); end of the treatment (ET); and 2 years (2Y) after bleaching, using the Vita Classical shade guide.
Objective: To evaluate the effect of water storage time on the cytotoxicity of soft liners.
Methods: Sample discs of soft liners Dentusoft, Dentuflex, Trusoft, Ufi-Gel-P and denture base acrylic resin Lucitone-550 were prepared and divided into four groups: GN: No treatment, G24: Stored in water at 37°C for 24 h; G48: Stored in water at 37°C for 48 h, GHW: Immersed in water at 55°C for 10 min. To analyse the cytotoxic effect, three samples of each group were placed in tubes with Dubelcco's Modified Eagle Mediums and incubated at 37°C for 24 h.
Background: Tooth sensitivity has been reported with in-office tooth bleaching. The authors conducted a study to evaluate whether the use of a desensitizing agent before in-office bleaching decreased this sensitivity.
Methods: Before in-office bleaching with a 35 percent hydrogen peroxide gel (three applications of 15 minutes each), clinicians applied a placebo gel on the buccal surfaces of all teeth in 15 participants in the control group, which was left undisturbed for 10 minutes.
