Antibiotic use in dentistry of bacteria from advanced caries. The first line of treatment is the removal of the source of inflammation or infection by local operative measures. Generally, the abscess can be eradicated through surgical drainage alone; however this is sometimes inadequate. Therefore, systemic antibiotic treatment may be required, but only if there is evidence of spreading infection. As the bacteria involved are known, antibiotic therapy selection can be specific, based on published susceptibilities. Penicillin in the form of amoxicillin is the most common antibiotic to use. However, 3% of the patient population is allergic to penicillin, so erythromycin is often used in
Antibiotic properties of nanoparticles Antibiotic properties of nanoparticles Nanoparticles have been studied extensively for their antimicrobial properties in order to fight super bug bacteria. Several characteristics in particular make nanoparticles strong candidates as a traditional antibiotic drug alternative. Firstly, they have a high surface area to volume ratio, which increases contact area with target organisms. Secondly, they may be synthesized from polymers, lipids, and metals. Thirdly, a multitude of chemical structures, such as fullerenes and metal oxides, allow for a diverse set of chemical functionalities. The key to nanoparticle efficacy against antibiotic resistant strains of bacteria lies in their small size. On the nano
