Note the presence of two double bonds, leading to dense cross-linking. From a chemical point of view, the hw-GMA exhibits low shrinkage on polymerization (cure), so as to reduce the probability of unwanted bacteria, and so on, entering between the filling and the remaining natural tooth material (115). [Unfortunately, an effective expanding polymerization for dental applications has yet to be developed see (116).]... 

Several experiments have shown the bactericidal effect of fluoride ions at high concentrations [180,181]. This effect generally occurs at concentrations well above those generally observed in saliva however, the use of fluoridated toothpaste or dental topical applications of fluoride may temporarily elevate the fluoride concentration in the oral cavity to bactericidal levels. It has been demonstrated that fluoride affects the metabolism of oral bacteria and reduces its acid tolerance. It is most effective at acidic pH values and, for example, fluoride levels as low as 0.1 mM can cause the complete arrest of glycolysis by Steptococcus mutans. It has been suggested that modifying the biological fluids related to the presence... 

In-Vivo Percutaneous Implant Experiment. The principle of percutaneous attachment has extensive application in many biomedical areas, including the attachment of dental and orthopedic prostheses directly to skeletal structures, external attachment for cardiac pacer leads, neuromuscular electrodes, energy transmission to artificial heart and for hemodialysis. Several attempts to solve the problem of fixation and stabilization of percutaneous implants(19) have been made. Failures were also attributed to the inability of the soft tissue interface to form an anatomic seal and a barrier to bacteria. In the current studies, the effect of pore size on soft tissue ingrowth and attachment to porous polyurethane (PU) surface and the effect of the flange to stem ratio and biomechanical compliance on the fixation and stabilization of the percutaneous devices have been investigated.(20)... 

Brenn et al. [ 153] compared the efficacy of antibiotics commonly used in dental and oral clinical practice in application to the bacteria most frequently isolated in odontogenic infections (S. viridans, Peptostreptococcus spp, Prevotella intermedia, Porphyromona gingivalis and Fusobacterium nucleatum) based on pharmacokinetic and pharmacodynamic (PK/PD) analyses (effect of the human body upon the drug, reflected by the plasma concentration profile-pharmacokinetics, and the effect of the drug upon the body, as defined by the minimum inhibitory concentration, or MIC-pharmacodynamics). Antibiotics commonly used in dental practice, such as erythromycin, metronidazole or azithromycin, were found to be ineffective in apphcation in over 30% of the strains (39.1%, 50.5% and 33.2%, respectively) [154]. 

The thermodynamic model is, like the DLVO theory, only applicable for the adhesion in vitro. Both models are based upon non-specific interactions occurring between particles (cells) and solid surfaces. In vivOr or under in vivo like conditions, specific interactions also have to be taken into account. Such specific interactions have been shown to mediate adhesion between bacteria and natural substrata, such as adhesion of streptococci to dental enamel,29 y adhesion of E. coli to uroepithelial cells.30 Although not clearly demonstrated for the bacterial adhesion to synthetic polymers, it is highly possible that specific interactions, e.g. between bacterial surface proteins and protein layers adsorbed on the polymer surface, play an important role as well.
