background there is inconclusive evidence about the relationship between toothbrush wear and plaque removel. the aim of this study was to compare the effectiveness of new and 3 month-old toothbrush in the removal of dental plaque. material and methods in a randomized single blind clinical trial 63 students attended from awaz dental school. subjects were divided to three groups. plaque was score...

OBJECTIVES The diagnosis of peripheral pulmonary lesions (PPLs) often involves endobronchial ultrasound (EBUS)-guided transbronchial biopsy (TBB), washing and brushing. Certain echoic features of PPL have been associated with biopsy yield. This study compared yields of TBB and bronchial washing (TBBW) with those of TBBW plus bronchial brushing and analysed the associations between clinical and ...

This paper discusses the methodology used to determine the optimal ion-exchange column size to process all separate batches of feeds from acid mine drainage wastewater. The optimal design ensures the best utilization of resin material and therefore results in a minimum amount of spent resins. Ion exchanger materials have been studied for removing heavy metals from a metal bearing wastes. For th...

CONTEXT Fluid analysis obtained by EUS guided FNA is used to aid in diagnosis and management of cystic lesions in the pancreas. Complementing fluid aspiration with brushing of cyst wall may increase the cellular yield. OBJECTIVE To compare cellular yield of pancreatic cyst FNA with and without wall brushing. DESIGN Comparative study. SETTING Tertiary referral centre. PATIENTS Fifty-one ...

Associations have been reported between periodontal disease and increased cardiovascular disease risk, as well as between healthy self-reported tooth brushing behavior and reduced cardiovascular disease risk. We examined the association between self-reported tooth brushing behavior and the risk of metabolic syndrome (MetS) using a large medical check-up database. A total of 12,548 medical check...

BACKGROUND AND STUDY AIMS Endobiliary brushing during endoscopic retrograde cholangiopancreatography (ERCP) is the main technique used to diagnose a malignant stricture, but has a poor sensitivity. This study evaluated the diagnostic performance of bile aspiration associated with biliary brushing during ERCP to diagnose a malignant stricture, compared to brushing alone. PATIENTS AND METHODS B...

BACKGROUND Conventional bronchoscopy with brushing alone for diagnosing peripheral pulmonary lesions (PPLs) is of low sensitivity. A manual mapping method was introduced and evaluated in this study, which could be routinely applied with bronchoscopic brushing to improve the sensitivity for malignant PPLs. METHODS This mapping method involves the bronchoscopist drawing the route with a series ...

BACKGROUND Tooth brushing (with fluoridated toothpaste) is the most cost-effective intervention in dentistry and it is widely recommended to preserve good oral health. We aimed to determine the frequency of tooth brushing and the variables associated with this practice in schoolchildren living in southeast Mexico. MATERIAL AND METHODS A cross-sectional study was carried out in 1644 schoolchil...
