[Antibiotic therapy of bacterial infections of the oral cavity].
More than 300 commencial bacterial species may be found in the oral cavity. Other microorganisms, such as mycoplasms, mycetes, protozoa and viruses are present as well. The virulency of the saprofites and additional contamination by outside microorganisms are factors determining the development of infectious process in the oral tissues. Moreover, streptococci and anaerobes are the most frequent aetiology agents. The antibiotic therapy should comply with the general treatment criteria, on the one hand, and should be specific for these microorganism, on the other. The penicillines (ampicillin, bacampicillin and especially amoxycillin) process pharmacokinetic properties which make them a favorable choice for treatment. These drugs are effective in case of streptococcal infections, with cariogenic processes involvement and dissemination (endocarditis, glomerulonephritis). Other, frequently used drugs are spiramycin, erythromycin, josamycin and myocamycin that are selectively taken up by the oral tissues and present in large quantities in the saliva. The macrolides have a large spectrum of action on microorganisms normally found in the oral cavity. Lincosamides (lincomycin and clindamycin) are active on anaerobes and are drugs of choice for treatment of staphylococcal osteomyelitis. Tetracycline therapy is restricted usually to parodontite cases caused by Actinobacillus actinomycetemcomitans and Capnocytophaga. In conclusion, the choice of antibacterial therapy should be based on the bacterial aetiology, as well as on the intrinsic drug characteristics (pharmacokinetic, side effects, toxicity etc.).
