title: [Analysis of the inhibitory capacity against bacterial growth of several materials of dental use. Preliminar].
abstract: Dental plaque is one of the reasons for odontogenic infection. Although multiple bacteria are involved in these processes, A.actinomycetemcomitans and S.mutans are considered directly responsible for localized aggressive periodontitis and caries respectively. On the other hand, it seems clear that the oral flora utilizes especially not well polished surfaces or without bacteriastatic capacity in order to obtain better adhesion. Based on those facts we expect to prove the inhibitory capacity "in vitro" of some materials used for teeth restoration and for the cementation of accessories against one common bacterium in the human flora and two pathogenic bacteria of the oral cavity. We prepared, following the manufacturer's instructions, 18 discs for each one of the materials used in the study (2 composites and 2 ionomeros of glass). 6 discs of each material are incubated with A. actinomycetemcomitans, S. mutans and E. coli. 3 of them are incubated directly on the discs and the other 3 are incubated previously in an artificial saliva for 24 days. From the results, should be highlighted that only one of the materials demonstrated inhibitory capacity against A. actinomycetemcomitans and E. coli. None of them demonstrated inhibitory capacity against S. mutans.
