발광 다이오드(Light Emitting Diode) 전동칫솔의 치은염에 대한 효과: 무작위 배정 임상시험 The effect of Light Emitting Diode electric toothbrush on gingivitis: a randomized controlled trial원문보기
목적: 이 논문의 목적은 발광 다이오드(Light Emitting Diode(LED))의 유무에 따른 전동칫솔의 항치태 및 항치은염 효과를 치은염 및 경도의 치주염 환자에서 관찰하는 것이었다. 연구 재료 및 방법: 30명의 환자를 실험군, 대조군으로 각각 15명씩 나누어 실험을 진행하였다. 실험군은 정상 작동의 LED 전동칫솔을 사용하였고 대조군은 LED가 나오지 않도록 개조된 동일 제품의 전동칫솔을 사용하였다. 기준(Baseline), 2주, 4주 후의 임상지표($L{\ddot{o}}e-Silness$ gingival index (GI), Quigley-Hein plaque index (PI))를 측정하여 Wilcoxon signed rank test, Mann-Whitney test를 통해 통계적 분석을 시행하였다. 결과: 실험군과 대조군 간의 시간에 따른 GI의 변화는 두 군 모두 시간에 따른 감소를 나타내었으나, 2주, 4주차에서 유의한 차이를 나타내었다. PI는 4주차에서 실험군에서 대조군보다 낮은 수치를 나타내었는데, 통계적으로 유의한 차이는 아니었다. 결론: 본 연구에서 LED가 장착된 전동 칫솔은 단기간의 연구에서 치은염의 감소효과를 보였고, 장기간의 관찰 시 치태의 축적을 감소시킬 수 있다 추측할 수 있었다.

Purpose: The aim of the present study was to compare clinical antiplaque and antigingivitis effect between Light Emitting Diode (LED) electronic toothbrush and electronic toothbrush without LED for gingivitis and mild periodontitis patients. Materials and Methods: 30 patients included in this study. 15 patients in experimental group used LED electronic tooth brush which has red and white LED within its head, and other 15 patients in control group used same product which specially modified that function without LED. Clinical parameters ($L{\ddot{o}}e-Silness$ gingival index (GI), Quigley-Hein plaque index (PI)) were measured at the baseline, 2 weeks and 4 weeks later. Wilcoxon signed rank test and Mann-Whitney test were used for statistical analysis. Results: Compare of GI change between experimental and control group with time, both groups showed that reduced GI, but lower GI values detected at 2 weeks and 4 weeks later in experimental group than control group. And lower PI values detected at 4 weeks later in experimental group than control group, but not statistically significant. Conclusion: Based on these results and within the limits of this study, the electronic toothbrush with LED could reducing gingivitis in a short period and infer that decreasing plaque accumulation in a long period.

문제 정의
The aim of the present study was to compare clinical antiplaque and antigingivitis effect between LED electronic toothbrush and electronic toothbrush without LED for gingivitis and mild periodontitis patients.
15-18 The white LED was combination of blue, red, and green light sources. These reports were related with our research, using toothbrush with LED decrease gingival inflammation.
제안 방법
To be included in this study, patients had to: have a minimum of 20 sound, natural teeth; have a negative history of antibiotic use during the preceding 2 weeks; have a mean Turesky-Quigley-Hein plaque index (PI) of at least 1.5; have a mean LöeSilness gingival index (GI) of at least 1.0.
대상 데이터
1, according to the Consolidated Standards of Reporting Trials (CONSORT) group statement. A total of 30 patients participated in this study and were randomly assigned in 1:1 ratio to the experimental groups and control groups, respectively. All subjects signed an informed consent after nature of the study was fully explained to them.
This study was performed at the department of periodontology, School of dental medicine, Dankook University, Korea.
데이터처리
To compare the difference of control group and test group as time goes by, Wilcoxon signed rank test was performed. And to compare of clinical parameter among baseline, 2 weeks and 4 week later in each group, Mann-Whitney test was performed. These analyses were performed by SPSS software (release 18.
To compare the difference of control group and test group as time goes by, Wilcoxon signed rank test was performed.
성능/효과
Based on these results and within the limits of this study, the electronic toothbrush with LED could reducing gingivitis in a short period and infer that decreasing plaque accumulation in a long period. However, longer research period and larger sample size will be needed to draw more definite conclusions on the reliability of toothbrush with LED.
후속연구
The sample size is quite small to show the statistical power, and the short period of research. Further comparative studies with larger sample size should be conducted besides the longer period of research, so as to increase the scientific and statistical power.
