PURPOSE This study evaluated the adhesion to acrylic resin specimens and biofilm formation capability of Candida albicans strains isolated from HIV positive subjects' oral rinse solutions. MATERIALS AND METHODS The material tested was a heat-cured acrylic resin (Acron Duo). Using the adhesion and crystal violet assays, 14 oral Candida albicans isolated from HIV-positive subjects and 2 referen...

BACKGROUND Fractures of acrylic resin dentures are a common occurrence in clinical dentistry. The denture may be fractured accidentally when dropped or while in service in the mouth due to flexural fatigue. OBJECTIVES The aim of this study was to compare the elastic modulus and the flexural strength between two heat-cured acrylic resins used in denture bases: a high-impact resin (Lucitone 199...

This study was divided into 3 phases. The 1st phase was the experiment in seven cadaver skulls to compare force from 2 techniques of weight load; interdental wiring and interdental wiring together with dental acrylic, with 1, 2 and 3 kilogram bar for 10 minutes. The evaluation was done by measuring the gap of the fracture line in a lateral radiograph. The force was calculated from the gap accor...

Quaternary ammonium methacryloxy silicate (QAMS), an organically modified silicate (ORMOSIL) functionalized with polymerizable methacrylate groups and an antimicrobial agent with a long lipophilic alkyl chain quaternary ammonium group, was synthesized through a silane-based sol-gel route. By dissolving QAMS in methyl methacrylate monomer, this ORMOSIL molecule was incorporated into an auto-poly...

PURPOSE To evaluate the in vivo and in vitro properties of collagen-coated acrylic microspheres and to compare them with polyvinyl alcohol (PVA) particles. METHODS Samples of 100- to 300-microns, 300- to 500-microns, 500- to 700-microns, and 700- to 900-microns collagen-coated acrylic microspheres and 200- to 300-microns PVA particles were suspended in solutions of 50% saline and 50% contrast...

Aim: To compare the effects of cast partial denture with conventional all acrylic denture in respect to retention, stability, masticatory efficiency, comfort and periodontal health of abutments. Methods: 50 adult partially edentulous patient seeking for replacement of missing teeth having Kennedy class I and II arches with or without modification areas were selected for the study. Group-A was t...

Aboriginal Australian acrylic paintings have long been considered representations of mythologically invested landscape. This understanding has been made problematic by recent writings on ‘dwelling’. As common usage of the term ‘landscape’ seems to prioritize vision, to suggest that the acrylic paintings are landscapes only strengthens the suspicion that they are artifacts of displacement or dis...

In the title 1/2 adduct, C(10)H(8)N(2)·2C(7)H(6)O(2)S, the dihedral angle between the pyridine rings is 18.41 (11)°. In the thio-phene-acrylic acid mol-ecules, the dihedral angles between the respective thio-phene and acrylic acid units are 5.52 (17)° and 23.92 (9)°. In the crystal, the components are linked via O-H⋯N hydrogen-bonding inter-actions, forming units of two 3-thio-phene-acrylic aci...

Background: The aim of this work was to study the output factors for Linac using different ionization chambers and build up caps. Materials and Methods: Output factors were measured for open square fields (3 × 3 cm to 40 × 40 cm) defined by collimator jaws for 6 and 15 MV photon beams from a Varian Clinac 2100C accelerator were measured. The measurements in air were performed using Com...

this study aimed to evaluate the cellular toxicity of two newly-released acrylic resins (futura gen and gc reline hard) in comparison with the conventional heat-cure resin (meliodent).sample discs from each acrylic resin were placed in 24-well culture plates along with l929 mouse fibroblast cell line. a mixture of the rpmi 1640 medium, antibiotics and 10% fbs was added to the plates and the spe...
