Here, we develop a simple molecular test for SARS-CoV-2 in saliva based on reverse transcription loop-mediated isothermal amplification. The has two steps: (1) heat with stabilization solution and (2) detect virus by incubating primer/enzyme mix. After incubation, samples containing the genome turn bright yellow. Because this is pH dependent, it can react falsely to some naturally acidic sample...

AIM To evaluate and compare the sorption, solubility, and compressive strength of three different glass ionomer cements in artificial saliva - type IX glass ionomer cement, silver-reinforced glass ionomer cement, and zirconia-reinforced glass ionomer cement, so as to determine the material of choice for stress-bearing areas. MATERIALS AND METHODS A total of 90 cylindrical specimens (4 mm diam...

The purpose of this in vitro study was to evaluate microleakage of two fluoride-releasing sealants in saliva contaminated and non-contaminated conditions. Twenty-four human third molars were randomly assigned to two groups: saliva contaminated and saliva non-contaminated teeth. In the contaminated group, the teeth were contaminated with 0.02 ml artificial saliva for 20 seconds and blowed dry af...

Fluoride varnishes, both the first and second generations, are effective in inhibiting caries, especially children adolescents, by reducing it on average 43% for permanent teeth 37% deciduous teeth. The aim of this study was to evaluate dynamics vitro fluoride ion release from first- (Duraphat) second-generation (MI Varnish Embrace Varnish) varnishes impact type varnish, time its application pH...

The midgut pH of gypsy moth (Lymantria dispar) larvae was significantly lower when larvae were fed acidic foliage. At 30 min after the start of a feeding bout, larvae feeding on bigtooth aspen (foliage pH = 6.04) had average midgut pH levels of 10.16, while larvae feeding on red oak foliage (foliage pH = 3.84) had average midgut pH levels of 9.36. Midgut pH was also significantly reduced when l...

OBJECTIVE Bond failure of brackets during orthodontic treatment is a common problem; which results in treatment interference, increased treatment time and prolonged clinical time for rebonding of failed brackets. The purpose of this study was to evaluate the effects of Coca-Cola and a non-alcoholic beer on the shear bond strength and adhesive remnant index (ARI) of orthodontic metal brackets in...

OBJECTIVES This study investigated the effect of red and white wine on color changes of nanofilled and nanohybrid resin composite. MATERIALS AND METHODS Sixty specimens of each resin composite were prepared. Baseline data color values were recorded using a spectrophotometer. Three groups of discs (n = 20) were then alternately immersed in red, white wine, and deionized water (as a control) fo...

OBJECTIVE The aim of this in vitro study was to examine potential changes and influences of prosthetic resin surface properties on Candida albicans adhesion after surface treatment or artificial ageing. MATERIALS AND METHODS Standardized specimens of a denture base resin and a veneering composite were prepared, polished, and randomly subjected to different surface roughness treatments or arti...

OBJECTIVES As the choice of suprastructure alloy to be combined with titanium for the oral cavity is still a much debated issue, the aim of this study was to investigate the electrochemical interaction of the suprastructure/implant couples under the determined experiment conditions. MATERIAL AND METHODS The potentiodynamic polarization curves and open-circuit potentials (OCP) of four UCLA typ...

Corrosion of orthodontic miniscrews or temporary anchorage devices (TADs) has been proposed as a contributor to inflammation, which in turn is a factor in the clinical success of miniscrews. The purpose of this study was to measure the electrochemical properties of orthodontic miniscrews in artificial saliva with and without fluoride. The corrosion properties of three miniscrew products (Vector...
