Abstract

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.

Highlights

Dental plaque, a biofilm present in the oral cavity, causes two of the most common oral infections: caries and gum disease
Due to the great mechanical properties, biocompatibility, and excellent esthetic properties, zirconia has been widely applied for the fabrication of crowns, bridges, and ceramic posts in medical ddeevnicteisst,rdyi.spZlraOy2s, a ceramic material used for good esthetic appearance, high mechanical strength, and high biocompatibility and is used in a wide range of indications, such as frameworks, implants, and abutments
This study explored the development of dental biofilm around the crown-gum interface, for three types of commercially available ceramic materials

Summary

Introduction

A biofilm present in the oral cavity, causes two of the most common oral infections: caries and gum disease. Any foreign bodies inserted in oral cavity may provide new niches for the microorganisms, promoting biofilm accumulation. Such biofilm formation on dental materials appears to be like that around natural tooth, which potentially contributes to damage to the mineralized tissues or infections of the soft tissues [8, 9]. It’s very good longterm stability and reliability was proven in a 10-year clinical study. These excellent material properties and the transformation behavior are explained by the yttrium oxide smtaabteilriizaaltfioornporifmZraOry2.cZrroOw2nhsasinatlhsoe been demonstrated as a double crown technique and has featured itself as an alternative to a gold alloy [10-. The white color of BioHPP frameworks provides a different esthetic approach than the conventional metal framework display does
