This study sought to evaluate the effect of different toothpastes with whitening action on the average surface roughness (Ra) of a microhybrid composite resin. Twenty-five specimens of composite resin were prepared and distributed randomly among 5 experimental groups (n = 5). Groups 1-3 were treated with whitening toothpastes: Close-up Extra Whitening, Colgate Ultra White, and Colgate Total 12 ...

INTRODUCTION Whitening toothpastes which have been accepted in populations may affect properties of enamel and restorative materials. The aim of this study was to compare the microhardness of human enamel and Z250 microhybrid composite resin after brushing with two whitening toothpastes. MATERIALS AND METHODS In this experimental study of enamel specimens, forty five freshly extracted human i...

objective: microbial plaque is among the main etiologies of periodontal disease, and tooth brushing with toothpaste is the most commonly used method of plaque control. this study aimed to compare the efficacy of tooth brushing with and without three different dentifrices.   methods: thirty dental students were randomly selected to participate in this clinical trial and were asked to refrain fro...

Purpose: To provide a brief overview of the diagnosis, epidemiology, etiology and clinical management of dentin hypersensitivity, to discuss technical approaches to relieve sensitivity, with special emphasis on dentin tubule occlusion and the clinical evidence for efficacy of desensitizing toothpastes based upon this approach, and to summarize the science behind a new dentifrice technology, bas...

This study was undertaken to investigate the number and types (fluoride or non-fluoride) of toothpaste products available in the Malaysian market based on the label. Thirty-five brands of toothpaste were identified, of which ten (29%) were specifically recommended for children. Two of the children's toothpaste recommended that children below seven years old use a pea size amount of toothpaste. ...

Objective: This study aimed to assess the effect of different types whitening toothpastes on microhardness and surface roughness composite resins. Material Methods: 120 discshaped samples each Clearfil Majesty Esthetic Gradia Direct Anterior resins were randomly assigned 4 groups, based toothpaste used [three toothpastes: Signal White Now (SWN), Colgate Optic (COW), Ipana 3D Luxe (IWL), one non...

Objective: The desire of individuals to have whiter teeth increases the interest in tooth whitening products. Our aim was vitro study effect hydrogen peroxide, blue covarine and active charcoal containing toothpastes on human teeth. Materials Methods: A total 40 extracted incisor were used study. To measure toothpastes, divided into four subgroups placed phantom jaw model. Then, daily brushing ...

Dental implants have increased the use of titanium and titanium alloys in prosthetic applications. Whitening toothpastes with peroxides are available for patients with high aesthetic requirements, but the effect of whitening toothpastes on titanium surfaces is not yet known, although titanium is prone to fluoride ion attack. Thus, the aim of the present study was to compare Ti-5Ta alloy to cp T...
