To analyze the effect of two mouthwashes on salivary pH and correlate it with age, buffer capacity and saliva flow rate in healthy volunteers, a crossover phase IV clinical study involving three age-based groups was designed. Two commercial mouthwashes (MW), Cool Mint ListerineR (MWa) and Periobacter R (MWb) were used. The unstimulated saliva of each individual was first characterized by measur...

AIMS To determine whether the oral health benefits of recommending twice daily brushing and rinsing with an essential oil mouthrinse (EOM) are perceived and measurable by dentists and also perceived by their patients at a 3-month recall visit. METHODS This is a monadic, open label, uncontrolled study involving 766 generally healthy Italian subjects aged 19-66 years, with mild to moderate leve...

objective(s): previous studies showed that skeletal muscle microcirculation was reduced in chronic heart failure. the aim of this study was to investigate the effects of endurance training on capillary and arteriolar density of fast and slow twitch muscles in rats with chronic heart failure. materials and methods: four weeks after surgeries (left anterior descending (lad) artery occlusion), chr...

The carbohydrate (CHO) concentration of a mouth rinsing solution might influence the CHO sensing receptors in the mouth, with consequent activation of brain regions involved in reward, motivation and regulation of motor activity. The purpose of the present study was to examine the effects of maltodextrin mouth rinsing with different concentrations (3%, 6% and 12%) after an overnight fast on a 2...

OBJECTIVE To demonstrate the efficacy of tonsil brushing in patients with chronic tonsillitis to remove the microbial biofilm on the tonsil surface using an in vitro model. DESIGN Specimens from patients undergoing tonsillectomy were evaluated prior to and following surface cleaning methods, including rinsing and brushing, using scanning electron microscopy (SEM). PATIENTS The study populat...

Mouth washing after inhalation of corticosteroids is effective for prevention of local adverse effects. We determined the amounts of drug residues remaining on the oropharyngeal mucosa following inhalation of budesonide (BUD) via a Turbuhaler (BUD-TH) (100 microg). Further, we studied the effects of mouth washing on the removal of drug residues by quantification of BUD in expectorated wash solu...

OBJECTIVES To investigate the neutralising effects of subsequent urea rinse on sucrose-induced decrease in plaque pH with interdental plaque pH telemetry. METHOD Six participants wearing partial lower prostheses which incorporated a miniature glass pH electrode were included. After 5 or 6 days of plaque accumulation on the tip of the electrode, the subjects rinsed with a 15 ml 10% sucrose sol...

PURPOSE The methylation of high-in-normal-1 (HIN-1) gene promoter in undifferentiated nasopharyngeal carcinoma (NPC) is studied. EXPERIMENTAL DESIGN The methylation status of HIN-1 in NPC cell lines, primary NPC, paired nasopharyngeal swabs, paired throat-rinsing fluid, and paired peripheral blood was assessed by methylation-specific PCR assay. The relationship between HIN-1 promoter methylat...

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 ...
