Effects of Water Sorption and Solubility on Degradation of Silorane and Methacrylate-Based Dental Composites.

Introduction: Wet oral environment may have deleterious effects on performance of the composites due to influences of water sorption and solubility. The study evaluated the hydrolytic degradation caused because of water sorption and solubility of silorane and methacrylate-based dental composites.

Methods: Ten disc samples (2 mm × 10 mm) were prepared.

Read, spot and translate.

We propose multimodal machine translation (MMT) approaches that exploit the correspondences between words and image regions. In contrast to existing work, our referential grounding method considers as the visual unit for grounding, rather than whole images or abstract image regions, and performs visual grounding in the language, rather than at the decoding stage via attention. We explore two referential grounding approaches: (i) implicit grounding, where the model jointly learns how to ground the source language in the visual representation and to translate; and (ii) explicit grounding, where grounding is performed independent of the translation model, and is subsequently used to guide machine translation.

Effects of silver nanoparticle-based antimicrobial formulations on the properties of denture polymer: A systematic review and meta-analysis of in vitro studies.

Statement Of Problem: Denture stomatitis and other oral infections are prevalent in denture wearers and can be treated effectively with an antimicrobial agent such as a silver nanoparticle-based polymer. However, the physical properties of the denture should not be adversely affected by the addition.

Purpose: The purpose of this systematic review and meta-analysis of in vitro studies was to analyze the effects of a silver nanoparticle-based antimicrobial resin on the properties of polymethyl methacrylate(PMMA)-based denture resin.

X-ray diffraction analysis of hydroxyapatite-coated in different plasma gas atmosphere on Ti and Ti-6Al-4V.

Objective: The aim is to study the effect of plasma working gas on composition, crystallinity, and microstructure of hydroxyapatite (HA) coated on Ti and Ti-6Al-4V metal substrates.

Materials And Methods: Ti and Ti-6Al-4V metal substrates were coated with HA by plasma spray using four plasma gas atmospheres of argon, argon/hydrogen, nitrogen, and nitrogen/hydrogen. The degree of crystallinity, the phases present, and microstructure of HA coating were characterized using X-ray diffraction and scanning electron microscopy.

Effect of finishing/polishing techniques and time on surface roughness of esthetic restorative materials.

Background: Surface roughness associated with improper finishing/polishing of restorations can result in plaque accumulation, gingival irritation, surface staining, and poor esthetic of restored teeth. The study aimed to evaluate the efficiency of various finishing and polishing systems and time using various procedures on surface roughness of some esthetic restorative materials.

Materials And Methods: In this study, samples of two composite materials, compomer and glass ionomer cement (GIC) materials, were fabricated.

Clinical profile of geriatric acute kidney injury in a tertiary care center from south India.

The incidence of acute kidney injury (AKI) is high in the elderly, who comprise an ever-growing segment of the population. Elderly patients pose a different set of diagnostic and therapeutic challenge owing to their associated comorbidities. AKI in the elderly is associated with an increased risk of mortality, morbidity, prolonged length of stay, and progression to chronic kidney disease.

Unusual presentation of systemic lupus erythematosus.

Bullous systemic lupus erythematosus is a rare distinctive subepidermal blistering disorder that can occur in patients with systemic lupus erythematosus (SLE). It is histologically characterized by a neutrophil-predominant infiltrate in the subepidermal region with deposition of immunoglobulins (IgG, IgA, IgM), C3, and auto-antibodies against collagen VII. Herein, we report a case of a 13-year-old girl who presented with bullous SLE and Class III lupus nephritis, which is extremely rare at this age.

Pregnancy-related acute kidney injury: An analysis of 165 cases.

Pregnancy-related acute kidney injury (PRAKI) contributes to 3-7% of overall acute kidney injury (AKI) cases in Indian subcontinent. The aim of this study was to determine the outcomes of PRAKI and risk factors associated with renal injury and maternal mortality. One hundred and sixty-five patients with PRAKI, seen at M.

evaluation of cytotoxicity and corrosion behavior of commercially pure titanium and Ti-6Al-4V alloy for dental implants.

Purpose: The aim of this study was to investigate the cytotoxicity in human gingival fibroblast by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and corrosion behavior by potentiodynamic polarization technique of commercially pure titanium (Ti 12) and its alloy Ti-6Al-4V (Ti 31).

Materials And Methods: In the present study, cytotoxicity of Ti 12 and Ti 31 in human gingival fibroblast by MTT assay and the corrosion behavior by potentiodynamic polarization technique in aqueous solutions of 0.1 N NaCl, 0.

Idiopathic erythrocytosis in IgA nephropathy.

We report a case of idiopathic erythrocytosis in a 31-year-old male who was incidentally detected to have hypertension during his preemployment checkup. Urine routine showed proteinuria and hematuria. Biochemical parameters revealed raised serum creatinine, and histological findings of the renal biopsy showed IgAN.

Comparative study of sorption and solubility of heat-cure and self-cure acrylic resins in different solutions.

Objective: The objective of this study was to compare the sorption and solubility of heat-cure and self-cure acrylic resins in different solutions.

Materials And Methods: One heat-cure acrylic resin (Trevalon) and one self-cure acrylic resin (Rapid Repair) were studied. Five groups of square-shaped specimens (20 mm × 20 mm × 2 mm) were prepared for each acrylic resin and then immersed in five solutions: distilled water, artificial saliva, denture cleansing solution, distilled water, and denture cleaning solution for 12 h alternatively, artificial saliva and denture cleaning solution for 12 h alternatively at 37 ± 2°C, and tested sorption and solubility by weight gain/loss method, respectively, after 1, 6, and 11 weeks.

Postpartum acute kidney injury: a review of 99 cases.

Postpartum acute kidney injury (PPAKI) constitutes an important cause of obstetric AKI. It is associated with high maternal and fetal mortality in developing nations. The aim of this study is to survey the etiology and outcomes of PPAKI in a tertiary care Indian hospital.

Evaluation of Cytotoxicity of Silorane and Methacrylate based Dental Composites using Human Gingival Fibroblasts.

Aim: The effects of leached substances from the restorative dental materials may induce local and systemic adverse effects. Thus the biological and toxic properties of the restorative dental materials must be compatible with the oral tissues or with general health. Therefore, the need for biocompatible restorative dental material implies the necessity of toxicity testing.
