Introduction:One-bottle light-cured adhesives systems have variable pH. In addition to ease of use, universal adhesives can be used in various restorations and different substrates. Due to the lack of studies, the purpose of this study was to compare the enamel and dentin micro-leakage of self-cure and light cure composite restorations using a universal bonding system. Materials & Methods:The ...

The primary objective of this project is to create a projected image 3D printer with the ability to produce a three-dimensional part. The system utilizes an ordinary overhead projector to project black and white images onto a film of UV curable photopolymer in order to selectively cure/harden the polymer. This project is focused around meeting the following objectives, (a) design a movable plat...

One of the decisive factors in obtaining the desired properties in coatings is their complete curing, which necessitates the study of kinetics of curing. In recent years, many studies have been conducted on the use of polyhedral oligomeric silsesquioxane (POSS) in coatings. Creating functional groups on POSS and using it in formulation can create new or improve the properties of coatings. I...

background & aim: esophageal cancer is one of the main common causes of death. the high prevalence of esophageal cancer in northern iran is an important public health problem. the main aim of this paper was to assess the factors affecting survival of  atients with esophageal cancer in neighbor provinces around the caspian sea using weibull mixture cure model and mixture cure model based on a no...

o bjectives: heat-polymerized acrylic resin has been the most commonly used denture base material for over 60 years. however, the mechanical strength of acrylic resin is not adequate for long-term clinical performance of dentures. consequently, fracture is a com- mon clinical occurrence, which often occurs in the midline of denture base.this study aimed to evaluate the efficacy of cold cure and...

In recent years, dual‐cure chemistry has been exploited to realize interpenetrating networks (IPNs) that provide enhanced thermo‐mechanical properties. this contribution, photoinduced curing of (meth)acrylates is used build the desired 3D structure, whereas thermally triggered polymerization reaction 2H‐chromene functionalized building blocks utilized create IPN. This strategy combines advantag...

Fluorescent dyes added to UV-cure resins allow the rapid fabrication of fluorescent micropatterns on standard glass coverslips by two-photon optical lithography. We use this lithographic method to tailor fiduciary markers, focal references, and calibration tools, for fluorescence and laser scanning microscopy. Fluorescent microlithography provides spatial landmarks to quantify molecular transpo...
