OBJECTIVE To evaluate and compare the effectiveness in reducing plaque of a fluoride dentifrice containing baking soda and a non-baking soda fluoride dentifrice containing an antimicrobial (triclosan/copolymer) system after a single brushing and over a four-week period of daily brushing. METHODS A total of 207 subjects completed this randomized, blinded, parallel-group clinical study. Twenty-...

In this study, scaling, polishing and daily tooth brushing were performed in 20 beagle dogs, and the number of oral bacteria was determined using a bacterial counter. The dogs were randomized into the scaling (S), scaling + polishing (SP), scaling + tooth daily brushing (SB) and scaling + polishing + tooth daily brushing (SPB) groups. Samples were collected from the buccal surface of the maxill...

BACKGROUND Manufacturers' recommendations on cleaning of tracheostomy tubes focus on general warning information and non-specific manual cleaning procedures. The aim of this experimental study was to evaluate different reprocessing methods and to determine the mechanical integrity and functionality of tracheostomy tubes following reprocessing. METHODS Sixteen cuffed or un-cuffed tracheostomy ...

Artificial teeth on upper and lower typodonts were coated with a plaque. After a drying period, the typodonts were mounted onto the robot system and the teeth were cleaned by the robot for 2 minutes (1 minute upper and 1 minute lower typodont) at a brushing force of 1.8 2.1 N for the 3D toothbrush and 1.1 1.4 N for the sonicare Plus brush. The different brushing forces were chosen in order to f...

Brushing is an effective method to control hypocotyl elongation in cucumbers (Cucumis sativus L. ‘Turbo’) grown in plug trays for transplanting. The amount of daily brushing and the number of days to brush for best performance was determined. Treatment with 10 strokes per day for the 4 days of maximal hypocotyl elongation was sufficient to reduce final hypocotyl length by 25%. More brushing did...

BACKGROUND The choice of sampling techniques in bronchoscopy with sampling from a visible lesion will depend on the expected diagnostic yields and the costs of the sampling techniques. AIMS The aim of this study was to determine the most economical combination of sampling techniques when approaching endobronchial visible lesions. METHODS A cost minimization analysis was performed. All bronc...

BACKGROUND The combination of endobronchial biopsy with cytological brushing is considered the best procedures for the diagnosis of lung cancer during bronchoscopy. AIM To asses the diagnostic yield for lung cancer (with visible endobronchial alterations at endoscopy) of three fiberoptic bronchoscopy procedures: endobronchial biopsy, cytological brushing and bronchial cytological washings. ...

OBJECTIVES The influence of toothbrushing duration and dentifrice quantity on fluoride efficacy against dental caries is poorly understood. This study investigated effects of these two oral hygiene factors on enamel remineralisation (measured as surface microhardness recovery [SMHR]), enamel fluoride uptake (EFU), and net acid resistance (NAR) post-remineralisation in a randomized clinical stud...

The paper describes a tool designed within the first stage of the European project INVISIP in order to explore geographical metadata in the site planning process. A visual data mining approach is applied to a database of geographical metadata to help the user find an optimal subset of the existing geographical datasets for his particular planning task. It allows the user to perform both confirm...

PURPOSE To assess the effect of brushing with different solutions on the abrasion resistance of two types of acrylic resin teeth. MATERIALS AND METHODS Maxillary premolars from two types of acrylic teeth (Biotone and Biotone IPN) were divided into six groups (n = 12), according to the solution used during brushing: distilled water (control), coconut soap, or dentifrice. A mechanical brushing ...
