herbal extracts have been successfully used in dentistry as tooth cleaning and antimicrobial plaque agents. the aim of this study was to evaluate the clinical effects of a dental gel containing barberry extracts (from berberis vulgaris) on gingivitis and microbial plaque control. a double blind clinical trial study was conducted in a dormitory on 45 boys aged 11-12 years having the same socioec...

background: surface microhardness is a physical property which access the effect of chemical and physical agents on hard tissues of teeth, and a useful way to examine the resistance of fluoride treated enamel against caries. the purpose of this study was to evaluate microhardness of enamel following ph-cycling through demineralization and remineralization using suspensions of dentifrices with d...

This study compared the levels of biofilm in maxillary and mandibular complete dentures and evaluated the number of colony-forming units (cfu) of yeasts, after using auxiliary brushing agents and artificial saliva. Twenty-three denture wearers with hyposalivation and xerostomia were instructed to brush the dentures 3 times a day during 3 weeks with the following products: Corega Brite denture d...

Statement of problem: The effectiveness of fluoride dentifrices in reducing dental caries is well documented. However, not all fluoride dentifrices are equally effective Purpose: The objective of this experimental study was to compare fluoride uptake from Pooneh pediatric toothpaste and an ADA-approved pediatric dentifrice, in sound enamel of primary teeth. Materials and Methods: In an in vitro...

There is a lack of clinical studies comparing dentifrices with high fluoride (F) concentration. The aim was to evaluate a dentifrice containing 5,000 ppm F compared to a dentifrice containing 1,450 ppm F in caries-active adolescents. The design was a 2-year, single-blind randomized controlled trial and 211 adolescents of 279 (76%) completed the trial. The subjects were divided into two groups a...

Arginine is an important pH-elevating agent in the oral cavity. It has been incorporated in oral hygiene formulations to mitigate sensitivity and to prevent caries. In this investigation, the effects of sustained arginine dosing of dental plaque microcosms on bacteriological composition and pH were evaluated under controlled conditions. Plaque microcosms were established in constant-depth film ...

BACKGROUND The tooth whitening substances for extrinsic use that are available in Brazil contain hydrogen peroxide or carbamide peroxide. Several studies have attributed the appearance of lesions in the enamel morphology, including hypersensitivity, to these substances. Such lesions justify fluoride therapy and application of infrared lasers, among other procedures. However, there is no consens...

PURPOSE To compare the Jay Sensitivity Sensor Probe (Jay Probe), a new microprocessor-based, pre-calibrated instrument, with well accepted methods used to evaluate sensitivity, i.e. tactile response to the Yeaple Probe, air blast (Schiff scale), and patient responses by Visual Analog Score (VAS). METHODS Jay Probe assessments were accomplished using several approaches. With a cohort of 12 sub...
