Clinical evaluation of a root canal cement that contains paraformaldehyde

The effectiveness of a Formalin-containing root canal cement in endodontic treatment is evaluated. A total of 76 teeth from 73 patients was used in a series of root canal treatments in which it was impossible to fill the canal to the apex; results of treatment were compared with the results in teeth with conventionally filled canals. The evaluation of the results shows Formalin-containing cements to have a useful place in endodontic therapy.
