Antibiotic use in dentistry an antibiotic which incorporates sulphonamides and trimethoprim. It covers a broad spectrum of activity and in dentistry, is often used where there are clear signs and indications of bacterial infection that is sensitive to cotrimoxazole. This is determined by bacteriological sensitivity tests. Antibiotic use in dentistry There are many circumstances during dental treatment where antibiotics are prescribed by dentists to prevent further infection (e.g. post-operative infection). The most common antibiotic prescribed by dental practitioners is penicillin in the form of amoxicillin, however many patients are hypersensitive to this particular antibiotic. Therefore, in the cases of allergies, erythromycin is used instead.
Antibiotic show that both antibiotics and antibiotic resistance are ancient compounds and mechanisms. Useful antibiotic targets are those for which mutations negatively impact bacterial reproduction or viability. Several molecular mechanisms of antibacterial resistance exist. Intrinsic antibacterial resistance may be part of the genetic makeup of bacterial strains. For example, an antibiotic target may be absent from the bacterial genome. Acquired resistance results from a mutation in the bacterial chromosome or the acquisition of extra-chromosomal DNA. Antibacterial-producing bacteria have evolved resistance mechanisms that have been shown to be similar to, and may have been transferred to, antibacterial-resistant strains.
