| Research Abstract |
Patients with chronic tooth pain diagnosed as "Atypical tooth pain syndrome" were chosen as the subjects of this study. They were treated following the next strategies. (1) Confirmation of the absence of remaining vital pulp inside root canals, and the absence of infection in the root ligament or inflammation outside of root tips, performing root canal treatments. (2) No further root canal treatments after the application of Ca(OH)2 paste inside root canals, avoiding unnecessary root canal cleansing. (3) Prescription of some kinds of anti-depression medication.
Many of the patients accepted root canal filling after 3 months, and most of them didn't complain of pains after prosthetic treatment. This study showed the mechanism of atypical tooth pain syndrome and its typical symptoms, and indicatedthat三環系抗うつ剤の服用dramatically reduced the pain of the chronic pains.
