[Dowel cores, traditional and alternative. Bond test].

PMF represents today the best solution for the functional rescue of a tooth cured by endodontics. After a careful analysis of the international literature the Authors in this study examined the resistance of four different kinds of PMF under laboratory conditions, applying external pressure to them until a steady rise in lateral direction caused a fracture in the specimens under study. On the basis of the results obtained, the Authors deducted that among different models tested, traditional long modified PMF is the most adapt for tolerating load of compression to preserve the integrity of the dental residual structures.

[Impression materials. Dimensional stability after pouring].

The Authors wanted to establish which could be for every impression material tested, the most favourable moment for the development of plaster models in a steady environment conditions of temperature and relative humidity. From the analysis of the results obtained, we can clearly conclude that every material examined offers an ideal time interval in which we have to cast the model in plaster. This study aspires to be an invitation to all operator in the sector, to repeat this experience in their work environment to know and better manage the procedures and the materials used, from the taking the impression to the executing of the plaster model.

[The external pterygoid muscle. Functional aspects].

This study, starting from the revision of traditional anatomy proposed to value TMJ and its components through dissection of human TMJ, and especially to examine the anatomic function of the lateral pterygoid muscle. Twenty dissections of left human TMJ were made. Every block was fixed in solution of 10% of formalin and dissections were made to show every components of articulation. Further thin sections were made for histological examination. The purpose of the study was to evaluate the lateral pterygoid muscle as a single unit compared to the function.

[Cyanoacrylates as a cementation material in fixed prosthodontics].

The purpose of this study was to examine and compare, in the same experimental conditions, the effects and the behaviour of two different materials, using them for cementation of a prosthetic reconstruction: a cianoacrilic compound (B20 cianoacrilate 3M); a traditional cement of zinc phosphate (Harvard Cement). The comparative study with the optical microscope between butilcianoacrilate and traditional cement has shown minimum levels of marginal discrepancy for both materials examinated (about 13 microns). The high resistance of cianoacrilate to traction, compared with the other fixing cement, makes us conclude this study in the hope that further research could confirm and introduce this materials in the practice of prosthetic dentistry.
