Depending on the clinical context, objectives, and treatment requirements, a variety of prosthetic devices capable of artificially reconstructing the dental arches in a manner as customized as possible can be utilized in the treatment of complete edentation. The purpose of this study is to compare the efficacy of general vitamin B12 treatment vs the efficacy of local treatment accomplished through full dentures. The study was performed on a group of patients of Dental Faculty in Iasi.Because cyanocobalamin deficiency is typically treated parenterally, the current study proved the superiority of local treatment with complete dentures obtained through the crosslinked polymerization method, a much easier and less expensive way to perform the same treatment in the same time period.

Stone mastic asphalt is a gap-graded mix and is usually related to its high bitumen content and its skeleton-like constitution. Although famous for its durability, high resistance to fatigue and rutting, issues such as bleeding and premature aging do occur in the mix since it has a high bitumen content and voids due to its gap-graded structure. In order to encounter these problems from affecting the mix, some instances such as adding additives, rejuvenators and stabilizers into the mixture has been implemented. Nowadays, nano materials are being used in the asphalt mixtures and nano titanium is being introduced as a modifier to the asphalt binder in order to improve the mechanical properties of the stone mastic asphalt mix. The related tests done in order to access the improvement are resilient modulus, dynamic creep, moisture susceptibility and binder drain down. The content of nano titanium used in this research are 1%, 2%, 3%, 4% and 5%. This study is done to assess the mechanical performance of stone mastic asphalt with nano titanium modified binder.
