The purposes of this study were to determine the characteristics of a sharpened scaler and planed epoxy resin surface under different sharpening conditions. Each scaler was sharpened with the following kinds of sharpening stones and sharpening strokes by using an originally designed sharpening
Ischaemic stroke represents one of the main causes of disability. According to the broad investigations, it is widely assumed that the contribution of inflammatory mediators is strongly involved in its pathogenesis. Hence, it seems that stroke treatment needs more efficient and inflammatory-targeted
BACKGROUND
Reversible vasoconstriction (RV) may cause ischaemic stroke (IS) in the absence of any other defined stroke aetiology. The three objectives of our study were to evaluate the frequency of RV in a prospective series of young IS patients, to describe the detailed clinical-radiological
OBJECTIVE
This study was conducted to compare the rate of abrasive wear and change in surface roughness of resin-modified and conventional acid-base glass ionomers when subjected to toothbrush-dentifrice abrasion.
METHODS
Two resin-modified and two conventional glass ionomers were used. Samples of a
BACKGROUND
The wear resistance of artificial teeth is important to the life of the removable prosthesis for the edentulous patient. The ability of artificial teeth to maintain a stable occlusal relationship over time may be influenced by this property.
OBJECTIVE
The purpose of this in vitro study
Pituitary apoplexy is characterized by a wide spectrum of clinical features. A quite rare case of painless thyroiditis, hypopituitarism and central diabetes insipidus (DI) followed by pituitary apoplexy was presented. A 61-year-old woman was admitted to our hospital in May, 1986 because of marked
BACKGROUND
Stroke is a leading cause of death in the industrialized world, and hypercholesterolemia may be a risk factor for stroke.
OBJECTIVE
To determine whether reducing cholesterol levels with HMGcoA (3-hydroxy-3-methylglutaryl coenzyme A) reductase inhibitors or other antilipidemic
BACKGROUND
In patients with extensive tooth loss, restoration of masticatory function and aesthetics is main concern for a prosthodontist.
OBJECTIVE
This study aimed to evaluate and compare differences in masticatory efficiency of patients treated with complete dentures made with either high impact
OBJECTIVE
To verify the effect of surface penetrating sealant on the roughness of posterior resin-based composites before and after mechanical toothbrushing.
METHODS
10 specimens of four different composites (Alert, Definite, Z100 and Prodigy Condensable) were made using a metal matrix (height 2 mm
OBJECTIVE
To compare the stain removal efficacy and enamel abrasivity of a new experimental dentifrice based on an ion-exchange resin mixture that releases calcium, fluoride, phosphate and zinc ions (named NMTD1), to four commercially available dentifrices: Crest Extra-whitening toothpaste, Crest
This study evaluated weight loss and surface roughening after toothbrushing of different resin composites: one packable (Solitaire 2, Heraeus Kulzer), one microhybrid (Charisma, Heraeus Kulzer), one nanohybrid (Simile, Pentron) and one microfilled (Durafill VS, Heraeus Kulzer). Cylindrical specimens
OBJECTIVE
This study was undertaken to study the effect of three most commonly used dentifrices for denture cleaning and to find out any positive association between number of strokes by toothbrush and surface roughness of acrylic resin.
METHODS
About 40 acrylic rectangular blocks with high finish
OBJECTIVE
To evaluate the effect of 2 postpolymerization treatments on toothbrushing wear (weight loss) and surface roughness of 3 autopolymerized reline resins--Duraliner II (D) (Reliance Dental), Kooliner (K) (Coe Laboratories), and Tokuso Rebase Fast (T) (Tokuyama Dental)--and 1 heat-polymerized
OBJECTIVE
To determine the relationship between margin preparation design and resin-composite type on microleakage with or without re-application of surface-penetrating sealant.
METHODS
Class-I resin-composite restorations were completed for 128 extracted human molars. Half of the margins were
To test the effectiveness of sealant and flowable composite coating on eroded enamel, dentin and cementum under erosive/abrasive challenges in vitro.
A total of 108 tissue sections (36 each for enamel, dentin and cementum) from third molars were assigned to three groups: Seal & Protect sealant
