Abstract
목적:본 연구에서는 새로 개발된 다이오드 레이저 제품을 이용하여 레이저 파워에 따른 온도변화와 박테리아 멸균 비교 실험을 통하여 기존 제품과의 임플란트 주위염치료에 대한 효과를 비교 실험하였다.
연구 재료 및 방법: 808 nm Diode laser와 810 nm Diode laser를 사용하여 디스크에 레이저를 60초간 조사하였으며, 출력은 1 - 2.5 W로 설정하였다. 온도측정 모듈과 온도측정 프로그램을 이용하여 disc 표면온도변화를 측정하였다. 또한, SLA, RBM이 코팅된 disc에 bacteria 도포 후, 808 nm Diode laser를 30초간 조사하였으며, 출력은 0.5 - 3 W로 설정하였다.
결과: 808 nm, 810 nm 두 장치 모두 출력이 증가함에 따라 온도 상승폭은 증가하였다. 모든 조건에서 810 nm laser를 조사하였을 때 초기온도상승속도, 하강속도 및 전후의 온도변화량은 808 nm laser 보다 높았다. 레이저 조사 후 티타늄 디스크 표면의 변화는 두 레이저 모두에서 관찰되지 않았다. Bacteria가 도포된 디스크에 808 nm laser를 조사한 결과, 출력이 증가 함에 따라 살균효과가 증가하는 것을 확인하였다.
결론: Diode laser를 임상에 적용하는 경우, 동일한 출력에서 온도의 변동폭이 적고 최대 상승온도가 낮은 808 nm laser 가 환자에 안전할 것으로 사료된다. 하지만 실제로 임상에 적용하기 위해서는 보다 다양한 안전성평가를 실시하여 장비에 대한 신뢰성을 확보하여야 할 것이다.
Purpose: We compared the effects of newly developed diode laser (Bison 808 nm Diode laser) on the treatment of peri-implantitis with conventional products (Picasso 810 nm Diode laser) by comparing the surface temperature of titanium disc and bacterial sterilization according to laser power. Materials and Methods: The titanium disc was irradiated for 60 seconds and 1 - 2.5 W using diode laser 808 nm and 810 nm. The surface temperature of the titanium disc was measured using a temperature measurement module and a temperature measurement program. In addition, in order to investigate the sterilizing effect according to the laser power, 808 nm laser was irradiated after application of bacteria to sandblasted large-grit acid-etched (SLA) and resorbable blast media (RBM) coated titanium discs. The irradiated disks were examined with scanning electron microscopy. Results: Both 808 nm and 810 nm lasers increased disk surface temperature as the power increased. When the 810 nm was irradiated under all conditions, the initial temperature rise rate, the descending rate, and the temperature change before and after was higher than that of 808 nm. Disk surface changes were not observed on both lasers at all conditions. Bacteria were irradiated with 808 nm, and the bactericidal effect was increased as the power increased. Conclusion: When applying these diode lasers to the treatment of peri-implantitis, 808 nm which have a bactericidal effect with less temperature fluctuation in the same power conditions would be considered safer. However, in order to apply a laser treatment in the dental clinical field, various safety and reliability should be secured.
