Medicine types used in dental surgery:
It aims to prevent the infections
Against cultured and described pathogen (antibiogramm)
Begin antibiotic therapy because the clinical symptoms and the supporting laboratory tests confirms the infection
Be effective against the pathogens
Necesarry concentration needed at the infected area
The antibiotics have different antimicrobial spectrums:
It effects one or two pathogen gruops (targeted therapy)
It effect more pathogen groups (empiric therapy)
The original spectrum effect of the antibiotics could narrows by developing antibiotic resistance!!
Treatment of an acute infection is usually 7-10 days. Managing a chronic infection may be longer time , for example Osteomyelitis (3-6 months)
kidney-, liver- and hematopoietic toxicity
Beacuse of the potential toxicity several antibiotics should not be given
Antibiotics used in dental surgery I.
Penicillin combined β lactamase inhibitor (Augmentin Duo 1g, Aktil Duo 1g)
Penicillin derivatives with widened spectrum (against G+,G- aeorob and anaerob bacteria) combined β lactamase inhibitor
(amoxicillin + clavulanate)
Therapeutic dose : 2 X 1g / day
Prophylaxis : 2 X 1g 1 hour before the treatment
General indications :
First line antibiotics in case of streptococcus, staphylococcus, enterococcus infection
Allergy, GI effects, morbillifrom rash, epilepsy
Clindamycin (Dalacin 150mg, Dalacin C 300mg, Klimicin 300mg)
