Abstract

The purpose of this study was to assess the incidence of flare-ups among patients who received endodontic treatment and to examine the correlation with pre-operative and operative variables. Analysis was in two aspects (a) overall incidence of flare-ups as expressed by a percentage of all patients visits and (b) percentage of flare-ups that occurred as related to various factors suck as patient demo-graphics, diagnosis, and treatment procedures. 1. From the 840 teeth which were examined in this study, the total number of flare-ups was 13. 2. As to gender of patients, there was no significant difference in flare-ups. 3. As to tooth groups, there was no significant difference in flare-ups. 4. In the teeth with pre-operative symptom, there was a statistically significant higher incidence of flare-ups than the teeth without it. 5. In the teeth with apical periodontitis, there was a statistically significant higher incidence of flare-ups. 6. As to pulp and periapical status. non-vital teeth had a higher incidence as compared with vital teeth, irreversible pulpitis. 7. Multi-visit treatment resulted in the higher incidence of flare-ups than one visit treatment. 8. Re-treatment procedures had a statistically significant higher incidence of flare-ups than root canal treatment. In this study, overall percentages of flare-ups was $1.55\%$. It showed a statistically significant higher incidence related to pre-operative symptom, apical periodontitis, and re-treatment. There was no significant difference in flare-ups related to gender, tooth groups, and fistula.

본 연구는 근관치료시의 flare-up발생률과 환자의 술 전 상태 및 술식 등에 따른 flare-up의 발생 빈도를 알아보고자 한 것이다. 자료는 근관치료 받은 840개 치아로부터 얻었다. 심한 동통이나 종창으로 응급 내원하여 보다 적극적인 치료를 필요로 하는 경우만을 flare-up으로 분류하였다. 1. 전체 840개 치아 중 13개에서 발생, $155\%$의 발생률을보였다. 2. 성별 및 치아에 따른 유의차는 없었다. 3. 술 전 증상이 존재하는 경우 및 치근단 병소가 존재하는 경우가 높은 발생률을 보였다. 4. 무수치의 경우가 생활치나 비가역성 치수염 보다 높은 발생률을 보였다. 5. 다내원 근관치료의 경우 높은 발생률을 보였다. 6. 재근관치료시 높은 발생률을 보였다. 이상의 결론을 통해 flare-up은 환자의 술 전 증상, 치아의 술 전 상태 및 재근관치료 여부에 따라 높은 발생률을 보이고 있음을 알 수 있었다.
