본 연구는 부산대학병원 구강내과로 내원하여 삼차신경통으로 진단되어 사전에 실험에 대한 동의를 한 환자 20명(여자 13명, 남자 7명, $42{sim}77$세, 평균$58.20{pm}16.99$세)을 연구대상으로 저출력레이저 조사전,후 전류인지역치검사를 하여 다음과 같은 결과를 얻었다. 1. 레이저 조사전,후 이환측과 비이환측의 CPT값의 차이는 없었다. 2. 레이저 조사후 이환측과 비이환측의 CPT값 변화에 유의성은 없었다. 3. 하지만 레이저 조사후 이환측과 비이환측의 $A{eta}$섬유의 경우 CPT값이 증가하는 경향을 보였다.
The purpose of this study was to examine the effect of LLLT on current perception threshold in trigeminal neuralgia patients. Affected site and non-affected site was irradiated by GaAlAs diode laser. Current perception threshold was evaluated with $Neurometer^{(R)}$ CPT/C before and after LLLT. As an outcomes,CPT were obtained. We made a comparision of these values and the results were as follows. 1. There were no significant difference in CPT between affected site and non-affected site before and after LLLT irradiation. 2. There were no significant difference in CPT between affected site and non-affected site after LLLT irradiation. 3. But, CPT values of $A{eta}$ fiber incresed slightly on both site after LLLT irradiation
