Influence of Salivary Factor on Rampant Caries to Patients with Asthma

The aim of study is to assess the relation between corticostheroid dose for patients with asthma and the modifications of salivary factor, associated with the increase of dental caries prevalence. The study group included patients with asthma diagnosed in Clinical Hospital of Pneumophtisiology Iasi, treated with different corticostheroid doses. The patients were submitted to an oral assessment and salivary tests were performed (RFR, RFS, CT). Data were statistically processed using software SPSS 13. The statistical tests included Mann-Whitney, Kruskal-Wallis, Pearson Correlation. The results demonstrated that patients under therapy with glucocorticoides for asthma present significant changing of salivary rate and salivary buffering capacity

Matemathics Model Analysis of Biomechanical Behaviour of Three Dental Materials to Loading Related to Bruxism

The aim of study is to highlights the biomechanical behaviour of three dental materials during loading related to bruxism. It was created a finite element model of mandibular canin. The modelling was performed in Rhinoceros, AutoCad and the finite element analysis was performed in COSMOSWorks 2010. Occlusal loading was applied vertical and had a value of 1000N. The analysed cervical restorations were performed by dental amalgam, composite resins and glassionomer cements. The results confirm clinical observations related to the correlations between maximal occlusal forces to incisal margin of canin and maximal tensions to the level of cervical restorations
