하악 제3개구치의 외과적 발거시 VAS 및 MPQ를 이용한 동통의 평가에 관한 연구

A study of pain evaluation using VAS & MPQ in lower third molar surgical extraction

Pain evaluation was done on 64 patients by visual Analogue Scale (VAS), a type of Cross-Modality matching during the surgical extraction of 3rd molars in the department of oral and maxillofacial surgery. VAS is a linear scale which classifies according to the degree of discomfort during meals and conversation. The degree of pain was examined of 1 day prior to operation, operation day, and the postoperation first day, second day and seventh day. McGill s Pain Questionnaire (MPQ) was translated into Korean and further classified according to gender, age, location of tooth and analgesics were used for pain evaluation. the following results were obtained. 1. By the VAS scale, pain was higher in males compared to females in preoperation day and postoperation the 1st, 2nd, 7th day, NWC (number of words chosen), PRI(R) (pain rating index rank value) and PRI(S) (pain rating index scale value) on the MPQ were all higher in females than males. 2. VASI (degree of discomfort during meals) and VAS II (degree of discomfort during conversation) was high in subjects in their fifties Post-op. 1st, 2nd day and 7th day. Postoperation pain was highest in subjects in their forties. All VAS III (degree of pain) was the highest in the 4th decade. 3. NWC,PRI(R) and PRI(S) were the highest in subjects in their thirties. 4. For VAS I afloxan group was the most effective analgesic. For VAS II aspirin group was most effecive VAS III decreassed the most in the Post-op. 1st, 2nd day in aspirin group and the most effective in the Post-op. 7th day in afloxan group. Placebo was the least effective in all cases. 5. Distribution for location of tooth was the highest in the width 2 group and height 2 group. 6. In the correlation coefficient analysis. Sensory-NWC, Sensory-PRI(S), Affective-NWC and Affective-PRI(S) showed the highest intercorrelation. 7. The most frequently selected words in MPQ were throbbing, smarting, aching, rasping, troublesome and numb.
