The effects of nicotinate ethyl ester treatment on the gingival blood circulation of plaque induced inflammation in monkeys were determined. The blood flow, amount of hemoglobin and oxyhemoglobin rate (oxyhemoglobin/total hemoglobin) in gingival blood circulation in addition to bacterial colony forming units (CFU), gingival index (GI), probing depth (PD), loss of attachment (LA) and amount of g...

Introduction One of the most important factors for successful endodontic therapy is root canal cleaning. The difficulty involved in eliminating microorganisms, as well as their residual presence, warrants the use of root canal dressings after bio-mechanical preparation. Aim The aim of the study was to compare the diffusion ability between nonalcoholic calcium hydroxide-propolis paste, calcium...

Male leafroller moths, Choristoneura rosaceana (Harris) (Lepidoptera: Tortricidae) and Pandemis pyrusana (Kearfott), were evaluated for responses to a paste formulation loaded with a range of concentrations of the two species' pheromone blends and evaluated in a laboratory wind tunnel and in the field. Response criteria were flight, flight towards the pheromone source, and contact with the pher...

A plant-based paste fermented by lactic acid bacteria and yeast (fermented paste) was made from various plant materials. The paste was made of fermented food by applying traditional food-preservation techniques, that is, fermentation and sugaring. The fermented paste contained major nutrients (carbohydrates, proteins, and lipids), 18 kinds of amino acids, and vitamins (vitamin A, B1, B2, B6, B1...

This in vitro study evaluated the preventive potential of experimental pastes containing 10% and 20% hydroxyapatite nanoparticles (Nano-HAP), with or without fluoride, on dental demineralization. Bovine enamel (n=15) and root dentin (n=15) specimens were divided into 9 groups according to their surface hardness: control (without treatment), 20 Nanop paste (20% HAP), 20 Nanop paste plus (20% HAP...

This aim of this study was to investigate the biocompatibility of two experimental acetazolamide (AZ)-based pastes in the subcutaneous tissue of rats. Both pastes contained AZ as the main component in similar concentration. The vehicle in experimental paste 1 was saline, while experimental paste 2 was prepared with propylene glycol. Sixty polyethylene tubes were sealed at one end with gutta-per...

Purpose: To determine the efficacy of an in-office desensitizing paste containing 8% arginine and calcium carbonate relative to that of a commercially-available pumice prophylaxis paste in reducing dentin hypersensitivity instantly after a single application following a dental scaling procedure and to establish the duration of sensitivity relief over a period of 4 weeks and 12 weeks. Methods: T...

One of the main challenges facing the electronics manufacturing industry in solder paste printing for ultra-fine pitch surface mount and flip-chip assembly is the difficulty in achieving consistent paste deposit volumes from pad-to-pad. At the very small aperture geometries required for ultra-fine pitch and flip chip assembly, flow properties of the paste becomes one of the dominant factors in ...

Three kinds of taro paste were prepared with taro:water:sugar ratios of 1:0.33:1.4, 1:0.33:0.8 and 1:0.33:0.2. Results indicated that the paste with the highest sucrose concentration had the least hard texture. The retarding effect of sugar on hardness development and water mobility of the low concentration system was fructose > glucose > lactose > sucrose. The DSC characteristics showed that a...
