title: Paresthesia from N2. Report of a case.
abstract: A number of cases of paresthesia following the use of N2 or other paraformaldehyde-containing root canal cements have been reported. Since paresthesia is longlasting and not only an inconvenience but also disabling at times, such cements should not be used for obturating root canals.
