Abstract

Introduction: Microbial biofims have an important role in oral pathology, in the etiology of periodontitis, but also in contamination of some materials frequently used in dentistry. Objective: This study aims to determine the ability of adhesion and formation of microbial biofilms on the surface of common materials in dental medicine: the impression materials compared to other materials of general interest in dentistry. Material and methods: From September 2010 to December 2010, the microbial dental plaque was taken from a number of 50 patients with conjunct ceramic dentures on nickel-chromium metal support. Materials selected for determining the ability of adhesion and formation of microbial biofilms were inert substrates, consisting of: impression materials (irreversible hydrocolloids, silicones, polyethers) compared with diacrylic composite resins, zinc phosphate cement and self-curing acrylic resinS. They were followed the following points: - isolation and identification of microbial strains isolated from dental plaque; - quantitative assessment of the degree of training and adherence of microbial biofilms on inert layer surface mentioned above. Results: There was a wide variety of aerobic and anaerobic strains. It was shown that materials tested differently influence the rate of microbial adhesion and biofilm development. Thus, microbial biofilms grown on these inert substrates, gradually increase after the first 24 hours, have a maximum development at 72 hours, then followed by a sharp decline phase, without disappearing completely. Conclusions: experiments showed that materials tested differently influence the rate of adherence and the development of microbial biofilms. The capacity of adhesion and formation of microbial biofilms proved to be a strain characteristic
