Valutazione delle Temperature raggiunte dal Sistema E&Q Master tramite l’utilizzo di termocoppie

2009

INTRODUZIONE: Uno degli obiettivi del trattamento endodontico è l’otturazione tridimensionale del sistema dei canali radicolari. Un inadeguato sigillo dell’apice e un’incompleta otturazione canalare potrebbe essere la causa di disturbi post-trattamento. La guttaperca è il più comune materiale da otturazione usato e viene comunemente utilizzata in associazione con il cemento canalare. Sono da preferire tecniche che prevedono quantità minime di cemento, come la condensazione verticale a caldo. Questa tecnica implica l’uso di una sorgente di calore, come il sistema E&Q Master, che serve a termoplasticizzare la guttaperca. SCOPO DEL LAVORO: Valutare in vitro, mediante termocoppie, gli increment…

Current dental adhesives systems. A narrative review.

2012

Adhesive dentistry is based on the development of materials which establish an effective bond with the tooth tissues. In this context, adhesive systems have attracted considerable research interest in recent years. Successful adhesive bonding depends on the chemistry of the adhesive, on appropriate clinical handling of the material as well as on the knowledge of the morphological changes caused on dental tissue by different bonding procedures. This paper outlines the status of contemporary adhesive systems, with particular emphasis on chemical characteristics and mode of interaction of the adhesives with enamel and dentinal tissues. Dental adhesives are used for several clinical application…

Innovations in endodontic filling materials

2012

One of the goals of endodontic treatment is to achieve a complete, tridimensional, hermetic sealing of the root canal system to prevent the entry of microorganisms or their products through both the coronal and apical pathways. Gutta-percha is the most widely used material for root canal filling and despite its numerous properties, such as biocompatibility and thermoplasticity, it has however an important limit: the lack of adhesion to the canal walls. Attempts to address this problem have been made over the years by using endodontic cements capable of bonding to canal dentine but their tendency to resorption in time can compromise the quality of treatment. The first step towards a real adh…
