The use of resin composite in posterior restorations is an accepted practice, offering a predictable and minimally invasive treatment. Resin composite can be regarded as the "material of choice" for restoring many posterior teeth that have been damaged by caries or trauma. This textbook reviews the most current concepts, presents techniques for successful results, and demonstrates how to avoid common pitfalls.

Because FA maturation involves the vimentin intermediate filament (vIF) network, I also examined the role of vIFs in endoplasmic spreading. Wild-type cells expressing a dominant-negative vimentin variant incapable of vIF polymerization exhibit deficient endoplasmic spreading as well as defects in FA maturation. ALLN treatment restores FA maturation despite the lack of vIFs, but does not restore endoplasmic spreading. Consistent with a role for vIFs in endoplasmic spreading, adhesive structures do not contain vIFs when the endoplasm does not spread. Fln-depleted cells also exhibit a microtubule-dependent mistargeting of vIFs. Thus, I propose a model in which cellular force generation and interaction of vIFs with mature FAs are required for endoplasmic spreading. Additionally, I discuss future lines of investigation concerning the role of FlnA in the endoplasmic spreading mechanism as well as mechanosensitive functions of FlnA. Finally, I speculate on a potential application of endoplasmic spreading deficiencies as hallmarks of metastatic breast cancer.
