Global climate model (GCM) estimates of the equilibrium global mean surface temperature response to a doubling of atmospheric CO2, measured by the equilibrium climate sensitivity (ECS), range from 2.0° to 4.6°C. Clouds are among the leading causes of this uncertainty. Here we show that the ECS can be up to 1.3°C higher in simulations where mixed-phase clouds consisting of ice crystals and super...
"It was postulated that the ability of the dentifrice containing 8% arginine, calcium carbonate, and fluoride to precipitate mineral at the tooth surface, as well as provide the ability to occlude dentin tubules, might also provide protection from enamel erosion. This powerful combination of the ability to treat dentin hypersensitivity by blocking dentin tubules, combined with an ability to pre...
The aim of this randomized, controlled, split-mouth, clinical study was to differentiate and clinically qualify the effectiveness of different desensitizing agents in the treatment of painful symptoms caused by cervical dentin hypersensitivity (CDH). Two hundred-and-fifty-two teeth of 42 patients were distributed into seven groups (n = 36): G1 - placebo; G2, G3, G4 and G6 - fluoride varnishes; ...
The Wisconsin Card Sorting Test (WCST), a test of concept formation, was given to 49 schizophrenia inpatients in three blocks of 64 cards each with the second block comprising special instructions and trial-by-trial feedback. With the help of a psychometric algorithm based on linear regression analysis, the patients were classified according to their response to these specific interventions. Re...
This three-month, single-blind clinical study compared two whitening treatments, at-home with 10% carbamide peroxide and in-office with 35% hydrogen peroxide, for the degree of color change of teeth, color relapse and tooth and gum sensitivity. The degree of color change and color relapse was evaluated by using a colorimeter, shade guide and color slide photography. Teeth and gum sensitivity we...
Dentinal hypersensitivity is a common painful condition of the teeth, associated with the exposure of the dentin to external environment of the mouth. However, little is known about the etiology and predisposing factors, which can compromise management. The aim of this paper is to summarize existing information about epidemiology, mechanisms, etiology, differential diagnosis and treatment. Clin...
This study evaluated the degree of color change of teeth and the sensitivities of teeth and gums in an in vivo study. Ranir Whitening Wraps (WW2) and Crest Whitestrips Premium (WP2) were used twice a day and Ranir Whitening Wraps (WW1) were used once a day. Color evaluations occurred at baseline, after five and seven-day use of bleaching agent and 14 days post-bleaching. Color change was evalua...
After reading this article, the reader should be able to: • describe the process of nightguard vital bleaching and discuss indications and contraindications. • list the situations amenable to at-home whitening, including extended bleaching times for tetracyclinestained teeth. • explain how to treat side effects, such as tooth sensitivity during whitening. • discuss treatment options for a singl...
STATEMENT OF PROBLEM For restorations with excellent esthetics, an understanding of the optical properties of human dentin is needed. Little information is available on the translucency and color parameters of dentin and its relationship to tooth type and position. PURPOSE The purpose of this in vitro study was to investigate the translucency and CIELab color coordinates of human dentin in bo...
The Chinese Journal of Dental Research The characteristics of DH can be understood by dental practitioners based on the diagnosis, management and treatment of the condition. This means conditions that present symptoms mimicking DH must be ruled out. This definition provides challenges for dentists given that they must consider other potential causes for pain associated with tooth sensitivity. I...
