[Modified vertical condensation using warm gutta percha].
The Authors describe a new technique of endodontic obturation using thermoplasticized guttapercha; the first results, studied with a diaphanic method, suggest that this technique gives a full obturation of endodontic system.
[Critical analysis of the composition of endodontic cements].
The AA. discuss the problem of composition of root canal sealers; they precise the role and utility of single ingredients. They conclude that root canal sealers contain many unnecessary or harmful compoundings, as paraformaldehyde; so it's necessary to reduce the amount of root canal sealers introduced in the endodontic system.
[Lymphocyte subpopulations in inflammatory periapical lesions. A histopathological and immunohistochemical study in 10 cases].
The authors, thanks to the application of monoclonal antibodies, as well as the immunohistochemical technique of APAAP, have traced the qualitative and quantitative features of inflammatory cells implied in periapical lesions. Moreover ten patients, of whom 6 males and 4 females aged between 20 and 60 have been tested. The immunohistochemical reactions revealed a heterogeneous population of B and T (T4-T8) lymphocytes, together with myeloid trunk cells (granulocytes and histiocytes). The B lymphocytes form nearly 31.5% of all the inflammatory cell, whereas the T types form about 55.8. The granulo-histiocyte part implies 11.1% of all the inflammatory cells themselves. The average percentages of the roted inflammatory cells have been compared with two diagnostic categories of periapical granuloma and periapical cyst. However, by comparing the obtained results with the ones described by other authors, we notice agreement as for as qualitative analysis is concerned, while as for quantitative analysis, some differences are proved. Finally, this situation shows that the quantitative demonstration of inflammatory cell populations is only a moment in the development of immune reactions in the inflammatory tissue.
[Clinical suggestions on the use of calcium hydroxide in therapy of pulp necrosis].
The Aa. discuss the Bernard's method for therapy of pulpar necrosis, based on using of calcium oxide, know as "ocalexic method". They report clinical procedure and results of their experience.
[Experimental verification of the content of premeasured capsules of four different dental amalgams].
The Authors examine the problem of exactness of measure of weight in amalgam capsules and precision of ratio metallic powder-mercury. They study four materials and in some cases they found big want of precisione in dosing of capsules.

[Class II cavity for amalgam. Proposed new modifications related to material characteristics].
The Authors study conservative preparation designs for Class II amalgam restorations, with and without an occlusal dovetail. They propose the use of a high-copper filing admix allow in Clas II preparation with occlusal dovetail and the use of high-copper spherical alloy in box only restorations.
[Analysis of the composition of endodontic cements].
The Authors analyse the composition of endodontic pastes and emphasize the inutility of many substances. Therefore it is necessary to study a technique for reducing the pastes in endodontic obturations and for increasing guttapercha.
