The aim of this study was to compare the biofilm formation on three types of dental crown materials using adenosine triphosphate (ATP) driven bioluminescence as an innovative tool for the rapid chairside enumeration of oral bacteria and assessment of oral hygiene. The study group included 60 patients with fixed prosthodontics, made of three types of dental crown materials (BioHpp - Bredent, Ceramics - VITA VMK Master, and Zirconia - Vita In-Ceram) from which we have collected 60 specimen values using a luciferase-based assay system (system SURE II). The values of ATP were obtained with System SURE II device and statistically analyzed with Anova and Wilcoxon Test. The lowest value was shown for Zirconia, comparing with ceramics and BioHpp, but in time we have seen the increase of ATP for all three dental crown materials.

Non-immune salivary proteins-including lactoperoxidase, lysozyme, lactoferrin, and histatins-are key components of the innate host defense system in the oral cavity. Many antimicrobial proteins contain multiple functional domains, with the result that one protein may have more than one mechanism of antimicrobial activity. These domains may be separated by proteolytic cleavage, creating smaller proteins with functional antimicrobial activity in saliva as described for lysozyme, lactoferrin, and histatins. These small cationic proteins then exert cytotoxic activity to oral bacteria and fungi. Salivary histatin 5 initiates killing of C. albicans through binding to yeast membrane proteins and non-lytic release of cellular ATP. Extracellular ATP may then activate fungal ATP receptors to induce ultimate cell death. This mechanism for fungal cytotoxicity may be shared by other antimicrobial cationic proteins. Microbicidal domains of salivary and host innate proteins should be considered as potential therapeutic agents in the oral cavity.
