Buchanan plugger의 종류에 따라 System B Heatsource의 설정온도와 Buchanan plugger 상의 실제온도의 온도 차이의 여부와 정도를 thermocouple을 이용하여 평가하고자 본 연구를 시행하였다. 전기적 열전달기로는 System B HeatSource (Model 1005, Analytic Technologies, USA)을 사용하였고, digital display상의 설정온도는 200℃로 하고, touch mode를 사용하였으며 power level은 10으로 하였다. 충전기구로는 Buchanan plugger괴 F (Fine), FM (Fine Medium), M (Medium), ML (Medium Large)를 사용하였다. Plugger 표면의 온도측정을 위해 5개의 열전대를 1mm 간격으로 선단에서부터 4 mm 부위까지 부착하였다. 온도분석을 위해 열전대를 Data logger의 채널에 연결하고 매초마다 각각의 열전대의 온도가 기록되게 하였다. Heat control spring을 5초 이상 눌러 System B HeatSource 에서 열을 공급하게 하였다. Plugger 종류별로 동일실험을 10회 반복하여 다음과 같은 결과를 얻었다. 1. Buchanan plugger 종류에 따라 선단으로부터 1 mm 혹은 2 mm 부위에서 최고 온도가 나타났다(p<0.01). 2. 최고온도는 F plugger의 경우 215.25±2.28℃를, FM plugger의 경우 185.94±2.19℃, M plugger의 경우 169.51±9.12℃, ML plugger의 경우 160.79±1.27℃를 나타내어 최고온도는 F plugger에서 가장 높았으며 FM, M 및 ML plugger순으로 낮아졌다(p<0.01). 이상의 실험결과는 plugger는 제조회사에서 추천한 설정온도와 실제 측정온도가 일치하지 않고 선단 근처에 열이 집중되도록 고안되어 있으며, Plugger의 size가 커질수록 온도 상승이 적어지는 것을 시사한다.

This study was performed to confirm the actual temperature rise on the surface of Buchanan plugger by evaluating the temperature rise on the surface of it, the peak temperature of pluggers of various size using thermocouple. The heat carrier system 'System B Heatsource'(Model 1005, Analytic Technologies, USA) and the Buchanan pluggers of F, FM, M and ML sizes are used for this study. The temperature was set to 200℃ which Dr Buchanan's "Continuous wave of condensation" technique recommended on digital display and the power level on it was set to 10. The touch mode was used. Five thermocouples were placed in direct contact with the surface of each size of Buchanan's pluggers at 1 mm increments from the tip to the 4 mm length of shank. Each thermocouple was secured with cyanoacrylate adhesive and orthodontic resin block. The two wire leads of each thermocouple were connected to the appropriate channels of Data Logger. This was configured to simultaneously record input from the five thermocouples. The heat control spring was touched for 1, 2, 3, 4 and 5 seconds, and the temperature rise on the surface of the pluggers were measured at 1 sec intervals for more than 5 seconds with an accuracy of 0.01℃. Ten trials was determined for each plugger. The average of temperature rise and standard deviation was calculated for each size of plugger. The data were statistically analyzed by one-way ANOVA to determine their significance. The results as follows. 1. The position at which the temperature peaked was approximately at 1∼2 mm far from the tip of Buchanan plugger (p<0.01). 2. The peak temperature was 215.25±2.28℃ in F plugger, 185.94±2.19℃ in FM plugger 169.51±9.12℃ in M plugger, and 160.79±1.27℃ in ML plugger and the peak temperature was highest in F type and followed by in descending order FM type, M type ML type showed the lowest peak temperature(p<0.01). This results suggest that the actual temperature on the surface of the pluggers dose not correlate well with the temperature set on digital display. Heat concentrates aroun the tip. The larger plugger reveals lower temperature rise relatively.
