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.

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-associated diarrhea Antibiotic-associated diarrhea Antibiotic-associated diarrhea (AAD) results from an imbalance in the colonic microbiota caused by antibiotic therapy. Microbiota alteration changes carbohydrate metabolism with decreased short-chain fatty acid absorption and an osmotic diarrhea as a result. Another consequence of antibiotic therapy leading to diarrhea is overgrowth of potentially pathogenic organisms such as "Clostridium difficile". It is defined as frequent loose and watery stools with no other complications. Meta-analyses have concluded that probiotics may protect against antibiotic-associated diarrhea in both children and adults. Evidence is insufficient, however, regarding an effect on rates of "Clostridium difficile" colitis. However, citing conflicting data in the
