Objective: The object of this survey study was to assess the knowledge, attitude and practice dentists towards resin bonded bridges across Pakistan. Methodology: A cross-sectional conducted. self-administered questionnaire distributed among 500 Pakistan as a google form through electronic media. had three sections. First two sections details about purpose demographic respectively. In third sect...

Color vision deficiency (CVD) is a common ocular disorder that hampers patients’ color distinction capabilities, causing difficulties in their daily life routine. Till date, CVD cure not developed, and treatment courses, such as gene therapy, are yet to be applied on humans. Hence, patients opt for wearable visual aids tinted glasses/contact lenses, which achieve the latter by filtering out pro...

The evolution toward small-diameter and fast-growing plantation timbers such as the Pinus elliotti var. elliottii (Engelm) × caribaea hondurensis (Sénéclauze) (PEE×PCH) hybrids around world is producing large volumes of core wood that are falling short structural sawn timber grading requirements. Engineered products cross-laminated (CLT) glue-laminated (glulam) offer potential solutions to valu...

The purpose of this study was to confirm the dimensional accuracy of a newly developed injection pressing method for resin polymerization by making use of the internal electric resistance of resin to determine the optimal timing for resin injection. A new injection pressing polymerization pot with a built-in system to measure the internal electric resistance of resin was used for resin polymeri...

The penetration coefficients (PC) and tensile bond strengths of two pit and fissure sealants and a low viscosity bonding resin were evaluated. The penetration coeftYcients of the resin systems were determined at 22°C. Five determinations were done with each resin. Bonded test specimens were loaded to failure in the tensile mode in an Instron testing macl~’ne. Ten specimens were prepared with ea...

An improved monoclonal antibody immunoaffinity chromatography/high-pressure liquid chromatography/ fluorescence detection method was developed to measure aflatoxin (AF) exposure by quantifying AFM1 in human and rat urine samples. Analysis of different amounts of various AF metabolites showed that the immunoaffinity resin was highly selective for aflatoxin B1 (AFB1), AFB2, and AFM1. Recovery of ...

The purpose of this study was to assess the color of layered resin overlays and to test the early microhardness of dual cure resin cement (DCRC) light cured through the layered resin overlays. Resin overlays of 1.5 mm thickness were fabricated with the A3 shade of Z350 (Group 1L), the A3B and A3E shades of Supreme XT (Group 2L), and the A3, E3, and T1 shades of Sinfony (Group 3L) using one, two...

The purpose of this study was to evaluate the effect of degradation of a denture base resin on bond strength to relining resins. Denture base resin specimens were immersed under various conditions to simulate degradation. Tensile bond strength of denture base resin after immersion to relining resins was measured with or without surface grinding. The bond strength of denture base resin without g...
