Biodegradation of Dental Resin Composites and Adhesives by Streptococcus mutans: An in vitro Study
A major cause for dental resin composite restoration replacement is secondary caries attributed to Streptococcus mutans. Salivary esterases were shown to degrade resin composites. Hypothesis: S. mutans contain esterase activities that degrade dental resin composites and adhesives. Esterase activities of S. mutans were measured using synthetic substrates. Standardized specimens of resin composit...
متن کاملCorrelation of cariogenic bacteria and dental caries in adults.
Many studies suggest that mutans streptococci (MS), Lactobacillus (LB), and salivary buffering capacity are important risk factors for dental caries. However, target populations for most studies were children. In adult patients, the same risk factors affect the number of fillings or prostheses or secondary caries. It is therefore important to investigate these risk factors as predictors of cari...
متن کاملCeramic whisker reinforcement of dental resin composites.
Resin composites currently available are not suitable for use as large stress-bearing posterior restorations involving cusps due to their tendencies toward excessive fracture and wear. The glass fillers in composites provide only limited reinforcement because of the brittleness and low strength of glass. The aim of the present study was to reinforce dental resins with ceramic single-crystalline...
متن کاملNanoparticle-reinforced resin-based dental composites.
OBJECTIVE TiO(2) nanoparticles treated with the organosilane allyltriethoxysilane (ATES) are used to improve the mechanical properties of dental resin-based composites (RBCs, Z100, 3M ESPE). METHODS TiO(2) nanoparticles were sonically dispersed in an ethanol solution containing ATES. The modified particles were washed in pure ethanol and dried before being used as filler. Fourier transform in...
