THE EFFECT OF SODIUM HYPOCHLORITE USAGE IN THE TREATMENT OF DENTAL SIMPLE GANGRENE
Abstract:
The main factor incriminated for the occurrence of dental gangrene is represented by the anaerobe and aerobe microbial flora. This comes from the salivary environment where normally nonpathogenic species can be found; once entered in the endocanalicular environment they increase their virulence and become pathogenic. Nowadays, modern techniques are used to detect the exact identity of bacteria. Hence, in the endodontic space there was revealed the presence of various pathogenic species of bacteria, such as Streptococci, Staphylococci, Fungi, Candida Albicans, and Escherichia Coli etc. However, the main target of the endodontic treatment besides the exact identification of pathogenic strains is represented by the sterilization of radicular canals. Root canal sterilization is performed during the mechanical treatment using antibacterial irrigating agents; one of the mostly used irrigation agents during the endodontic treatment is the solution of sodium hypochlorite, which more recently is applied by irrigation systems using negative pressure. The goal of this work is to research, within the private dental office, the strict presence of etiologic agents responsible of producing the pulp gangrene, as well as the sterilization degree of root canals at the end of mechanic treatment. The identification of the strains was performed in the microbiology laboratory, namely on the culture medium. Thus, in 40.9 % of the studied cases, Streptococcus developed on the cultivated growth medium. Staphylococcus was identified in 31.81 % of the cases. Enterococcus colonies developed on growth cultures in 18.18 % of the cases, while Escherichia Coli were found only in 9.09 % of the cases. Actual sterilization of the canals was carried out according to a preset protocol, which included for this purpose the sodium hypochlorite solution.
