Microtubule-associated proteins of the highly conserved XMAP215/Dis1 family promote both microtubule growth and shrinkage, and move with the dynamic microtubule ends. The plant homologue, MOR1, is predicted to form a long linear molecule with five N-terminal TOG domains. Within the first (TOG1) domain, the mor1-1 leucine to phenylalanine (L174F) substitution causes temperature-dependent disorga...

Background/Aim. Polymerization shrinkage of filling materials is one the main disadvantages adhesive restorative dentistry. The objective study was to measure tooth cusps deflection caused by polymerization a resin-based dental material (RDM) in real-time using digital holographic interferometry (DHI) two groups cavities restored with and without an additional wall. Simultaneously, internal mec...

Composite restorations are popular because of their superior esthetics and acceptable clinical performance. But shrinkage is still a drawback. Polymerization shrinkage results in volumetric contraction, leading to deformation of the cusps, microleakage, decrease of marginal adaptation, enamel micro-cracks and postoperative sensitivity. A new class of ring opening resin composite based on silora...

STATEMENT OF THE PROBLEM Polymerization shrinkage stress in composite restorations may lead to microleakage. Clinical methods such as using low-shrinkage composites have been suggested to overcome this problem; however, there are controversies about their efficiency in decreasing the microleakage. PURPOSE This in vitro study was conducted to compare the microleakage of two low-shrinkage resin...
