To evaluate through computer software analysis, the efficacy of the use of a plaque disclosing agent as a visual guide for biofilm removal during professional mechanical plaque removal in terms of post-treatment residual plaque area (RPA).
Thirty-two healthy patients were selected and randomized in two groups to receive a session of professional mechanical plaque removal with air-polishing followed by ultrasonic instrumentation with (Guided Biofilm therapy-GBT) or without (Control) the preliminary application of a plaque disclosing agent as visual guide. The residual plaque area (RPA) was evaluated through re-application of the disclosing agent and computer software analysis, considering the overall tooth surface and the gingival and coronal portions separately.
A statistically and clinically significant difference between treatments is observed, with GBT achieving an RPA of 6.1% (4.1-9.1) vs 12.0% (8.2-17.3) of the Control on the Gingival surface and of 3.5% (2.3-5.2) vs 9.0% (6-13.1) on the Coronal, with a proportional reduction going from 49.2% (P-value = .018) on the former surface to more than 60% (P-value = .002) on the latter.
The application of a plaque disclosing agent to guide plaque removal seems to lead to better biofilm removal.
通过计算机软件分析评估，在专业机械性牙菌斑清除后，使用菌斑显色剂作为生物膜去除的视觉引导，在治疗后残留菌斑面积（RPA）方面的效果。
选择 32 名健康患者，随机分为两组，分别接受空气抛光后的专业机械性牙菌斑清除术加超声器械治疗（引导生物膜治疗-GBT）或不加（对照组）菌斑显色剂的初步应用作为视觉引导。通过重新应用显色剂和计算机软件分析，评估残留菌斑面积（RPA），分别考虑整个牙齿表面以及牙龈和冠部。
治疗之间存在统计学和临床显著差异，GBT 在牙龈表面的 RPA 为 6.1%（4.1-9.1），而对照组为 12.0%（8.2-17.3），龈下为 3.5%（2.3-5.2），对照组为 9.0%（6-13.1），龈下的比例降低了 49.2%（P 值=0.018）。
应用菌斑显色剂来指导牙菌斑的清除，似乎可以更好地去除生物膜。
