Formation of toxic volatile disinfection by-products during irrigation of infected root canals

The use of NaOCl has been universally adopted in endodontics for the disinfection of infected root canals. The use of EDTA, aids in the removal of the infected inorganic components of the forming smear layer, during root canal instrumentation. One of the side effects of the chemical interactions of NaOCl and EDTA, which has received little attention in the dental literature, is the formation of harmful volatile organic compounds (VOCs) and chlorinated disinfection by-products (DBPs). In this presentation, the release of VOCs and DBPs during instrumentation and irrigation of artificially infected root canal specimens, with 2.5% NaOCl and 17% EDTA is assessed in a novel tooth model. The formation of toxic VOCs and chlorinated DBPs indicate that risk assessment of the potential occupational and health hazards should be carried out in dental premises.
