Effect of iontophoresis and switching iontophoresis on skin accumulation of ketoprofen.
The effect of iontophoresis and switching iontophoresis on the skin accumulation of drugs was investigated. An acrylic diffusion cell mounted with electrode cells (bore: 2.2 cm) with circular platinum electrodes (diameter: 2.0 cm) was used for the skin accumulation study. The skin accumulation of fluorescein after non-switching and switching iontophoresis was macroscopically compared with that ...
متن کاملUltramorphology and dentine permeability changes induced by prophylactic procedures on exposed dentinal tubules in middle dentine.
OBJECTIVES The purpose of this study was to evaluate the changes in dentinal permeability (i.e. hydraulic conductance) after prophylactic treatment performed using prophy-powders with air-polishing system or prophy-pastes applied on exposed middle dentine. The changes in dentine morphology were evaluate by SEM. STUDY DESIGN Several prophylactic pastes or air-polishing powders were tested in t...
متن کاملThe efficacy of dentine adhesive to sclerotic dentine.
OBJECTIVE To evaluate the effect of a dentine bonding system to sclerotic dentine in comparison with normal dentine. METHODS The efficacy of the dentine bonding system to sclerotic dentine was examined by measuring wall-to-wall polymerization contraction gap width. The dentine cavity wall was pretreated with an experimental dentine bonding system with and without a dentine primer. The dentine...
متن کاملEffects of toothbrushing on eroded dentine.
It is an established assumption that eroded dental hard tissues are particularly prone to toothbrush abrasion. Only a few studies have aimed to show this for dentine and, if so, disregarded the complex histological structure of this tissue. Therefore, the present study sought (i) to investigate the effects of toothbrushing on eroded dentine and (ii) to analyze how the organic matrix influences ...
متن کاملEffect of hydrogen peroxide on intertubular dentine.
OBJECTIVES To evaluate the effect of 30% hydrogen peroxide on the surface changes and nanomechanical properties of intertubular dentine. METHODS Five freshly extracted human premolars were sectioned and two specimens were obtained from each tooth. Atomic force microscopy (AFM) images of dentine were taken. Baseline hardness and Young's modulus of intertubular dentine were determined using nan...
