title: [A comparative study of antibiogram methods employed in endodontic stomatological procedures].
abstract: The study demonstrates the importance of the antibiogram in the determination of the sensitivity of microbiocenosis of the infected dental canals. The methods and the techniques for the sampling of the pathological products are presented. The classical technique for antibiograms, consisting in horizontal diffusimetry is compared with the modern method of double-layer diffusimetry which employs a "redox" indicator (C.T.T.-triphenyl-tetrazolium-2, 3, 5-chloride) which accelerates the lecture of the results by altering the colour of the culture medium. The study was carried out in 200 patients and showed that the antibiotics with the widest spectrum on the microbiocenosis of the infected dental canals were, by order of efficiency, the following: erythromycin, chloramphenicol, ampicillin, and tetracycline. Antibiograms should be done in the shortest possible time, and the time for the lecture of the results was reduced from 36-48 hours in the case of the classical antibiograms to 16-18 hours in the case of the rapid technique. The shortening of the working time allows for a more rapid individualization of the treatment, and the preparation of antibiotic-incorporating pastes that will reduce the number of procedures to 1-2 procedures in the simple form of the pulp gangrene and to 3-4 procedures in the cases of complicated pulpal gangrene.
