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 synergy Antibiotic synergy Antibiotic synergy is one of three responses possible when two or more antibiotics are used simultaneously to treat an infection. In the synergistic response, the applied antibiotics work together to produce an effect more potent than if each antibiotic were applied singly. Compare to the additive effect, where the potency of an antibiotic combination is roughly equal to the combined potencies of each antibiotic singly, and antagonistic effect, where the potency of the combination is less than the combined potencies of each antibiotic. Clinical interest in synergism dates back to the early 1950s when practitioners noted that patients
