In vitro anti-biofilm effect of anti-methicillin-resistant Staphylococcus aureus (anti-MRSA) agents against the USA300 clone.

Objectives: Infection with a typical community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA), the USA300 clone, has become a worldwide epidemic. Biofilm formation at the site of infection is one of the reasons for the development of intractable infectious diseases resulting from this clone. Here we evaluated the in vitro antibiofilm effects of anti-MRSA agents to identify the most effective agent against the USA300 clone embedded in biofilms.

[New estimation method for displacement characteristic of teeth with occlusal force records].

Objectives: To establish adequate occlusion for prostheses, evaluation of degree of displacement of teeth and implant is essential. However, it cannot be attained without complex equipment, which limits clinical application. To develop a new estimation method for displacement characteristic of teeth and implant by both occlusal force of individual teeth and existing data on degree of displacement, the relationship between increase of total occlusal force and occlusal force of individual teeth was evaluated.
