Botched root canal treatment leads to hemiplegia
Paralysis of half of the body following endodontic surgery
A 32 year old dentist had become paralysed on one side of her body. No medical reason could be found but eventually she was "diagnosed" with idiopathic encephalitis (idiopathic meaning that the physicians couldn't pinpoint the cause[s] of her disease).
She carried four apparently perfectly done root-canal-treated teeth in her mouth. X-rays however revealed a metal file segment that had broken off during the cleaning of the root canal (apparently a "well-documented" occurrence) which subsequently had been pressed all the way into her jawbone when the canal was filled.
She underwent surgery to have the separated file segment removed. Within a matter of days she was free of all complaints, having regained full motor control of her body.
