چکیده مقدمه ضایعات لکه سفید یک عارضه شایع درمان ارتودنسی هستند. شیوع این لکه های سفید در بیماران پس از درمان ارتودنسی از 15 تا 85 درصد متغیر است. بیش تر مطالعات شیوع 50 تا 70 درصدی را گزارش کرده اند. این شیوع بالا با دشواری رعایت بهداشت دهانی در قوس های دندانی باند شده، همراه با تجمع و گیر آسان پلاک های باکتریال روی سطوح دندانی دور اجزای ارتودنسی ثابت توضیح داده می شود. هدف از این مطالعه مقای...
Polyol-ester-based carbon black pastes are used to either coat or penetrate flexible graphite, thereby increasing the thermal contact conductance of flexible graphite between copper surfaces. Paste penetration by up to an effective paste thickness (the volume of the penetrated paste divided by the geometric area of the flexible graphite) of 5 lm increases the conductance by up to 350%, 98% and ...
A chemically modified graphene paste electrode was prepared by incorporating appropriate amounts of graphene in a paste mixture, followed by electrodepositing Prussian blue (PB) and coating chitosan on the electrode surface. The electrode was able to bind ssDNA, and gave a better voltammetric response for complement DNA than did ordinary carbon paste electrodes. The response of the electrode wa...
During the freeze-form extrusion fabrication process for aqueous-based pastes, the sub-zero temperature environment aids the part in maintaining its shape by freezing the water present in the paste. The paste freezes very quickly when deposited on a substrate in a freezing environment. However, as the part’s height increases, the freezing time increases as the heat conduction rate to the substr...
This study was done to investigate the quality properties of beef jerky with soy sauce, red pepper paste, and soybean paste replacing salt. Sliced beef samples were cured in salt (control), soy sauce, red pepper paste, and soybean paste for 24 or 48 h and then dried at 70°C for 8 h. Treatments showed higher final moisture content and lower Na(+) concentration than the control after drying for 8...
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...
