This study evaluated the effect of retentive areas on onlay preparations on the dimensional alterations in condensation and addition silicone materials. A standard model with an onlay preparation was made. Each impression material was used through the double or simultaneous impression technique (n=25), resulting in a hundred impressions of the same model. Impressions were poured with type IV de...

AIM This randomised clinical trial (RCT) compared the clinical outcomes of three aesthetic full-coronal restorations (composite strip crowns, pre-veneered stainless steel crowns (SSCs) and pre-fabricated primary zirconia crowns) in carious and traumatised primary maxillary incisors. MATERIALS AND METHODS One hundred and twenty nine teeth in 39 children aged between 3 to 5 years were included....

INTRODUCTION Maxillary defects are usually rehabilitated by a prosthetic obturator. OBJECTIVE This study aimed to evaluate the functioning of obturators prosthesis in patients with unilateral defects after maxillectomy. METHODS Of 49 patients, 28 underwent to maxillectomy as a result of tumor ablative surgery, and acquired unilateral maxillary defects. Evaluation of the function was perform...

Many temporary cements are commercially available; therefore, it is necessary to indicate them for each clinical requirement with regard to the tensile strength of prosthetic retainers. Thus, the purpose of this study was to compare the retention of provisional crowns cemented with eight temporary cements, over full crown preparations with standardized mechanical principles as height, taper, an...

A composite gastro-retentive matrix for zero-order delivery of highly soluble drug alfuzosin hydrochloride (10mg) has been designed and characterized. Two systems containing polyethylene oxide (PEO), hydroxypropylmethylcellulose (HPMC), sodium bicarbonate, citric acid and polyvinyl pyrrolidone were dry blended and compressed into triple layer and bi-layer composite matrices. Dissolution studies...

Nutrient spiraling in theory and application provides a framework for comparing nutrient retention efficiency of urban streams to relatively unaltered streams. Previous research indicated that streams of the southwestern USA deserts are highly retentive of N because of N limitation, high productivity, and high channel complexity (in particular, extensive transient storage associated with the hy...

in this study, the effect of hole mulching application of zn and mn on acacia, elm, and plane nutrition was examined in the green spaces of isfahan. three different sites were chosen in a randomized complete block design using six treatments of: 1. cow manure compost, 2. cow manure vermicompost, 3. urban waste compost, 4. urban waste vermicompost, 5. dug hole refilled with the same soil coming ...

Study aims to design a Gastro retentive Drug Delivery System of Cefuroxime axetil (CA). CA is a broad spectrum beta lactam type of antibiotic. More specifically, it is a second-generation cephalosporin. CA has site specific absorption from upper gastro intestinal tract and in intestine it undergoes hydrolysis to cefuroxime having poor absorption. Unabsorbed drug causes high concentration of ant...

OBJECTIVE To evaluate the short-term results of an ultra high molecular weight polyethylene retentive cup in patients at high risk of dislocation, either primary or revision surgery. MATERIAL AND METHOD Retrospective review of 38 cases in order to determine the rate of survival and failure analysis of a constrained cemented cup, with a mean follow-up of 27 months. We studied demographic data,...

Dry matter production data for pure lucerne, overdrilled lucerne and pasture ark presented for 14 sites on pumice soils. On average, the annual dry matter yield of lucerne, harvested at early basal shoot movement, was 50% higher than from pasture, ranging froti 128% higher on a drought-prone soil where the pasture was dominant browntop to 33% on a more moisture-retentive soil type where the pas...
