Incidence of Bacterial Pathogens following Biomechanical Treatment of Root Canal, in Benin City, Nigeria

Abstract

A correlation exists between endodontic microflora in pulpal disease and endodontic treatment failure. This study presents data on the recoverable bacterial pathogens following biomechanical treatment of infected root canals. Standard endodontic procedure were used to access tooth pulp cavity, processed and fluid samples assessed for bacterial content, with standard microbiological protocols.
Aerobic Staphylococci, facultative Streptococci, E. Coli and Staphylococci were recovered from pre debridement samples, which were not substantially different from the first biomechanical debridement bacterial flora. Anaerobes, mainly Streptococci, lactobacilli and Bacteriodies spp were recovered following second biochemical treatment and inter-appointment dressing. A significant reduction in both aerobic and anaerobic bacteria isolates was observed prior to root canal obturation. Control of microbiologic activity within the root canal plays crucial role in periodontal healing and re-establishment of normal teeth integrity.
