The aim of this clinical pilot study was to compare the effect of tea tree oil with the effect of water and chlorhexidine on supragingival plaque formation and vitality. Eight subjects were asked to refrain from any kind of mechanical oral hygiene for 4 days after professional tooth cleaning (day 0), and to rinse with water instead for 1 week, with chlorhexidine in a second and tea tree oil in a third test week. The plaque index (PI), which was evaluated daily (days 1-4), served as a clinical control parameter. On the last day of the study (day 4), the plaque covering the front teeth was stained, photographed, and therefrom the plaque area (PA; %) was estimated using a digital measuring system. Each day of the study (days 1-4), the sampled plaque was examined using a vital fluorescence technique. Tea tree oil reduced neither the clinical parameters (PI and PA) nor the vitality of the plaque flora significantly. Within the limitations of the study design, it was determined that a solution with tea tree oil--utilized as ordinary mouthwash--has no positive effect on the quantity or quality of supragingival plaque.
这项临床初步研究的目的是比较茶树油与水和氯己定对龈上菌斑形成及活力的影响。八名受试者在专业牙齿清洁后（第0天）被要求4天内不进行任何形式的机械口腔卫生护理，然后在第一周用水漱口，第二周用氯己定漱口，第三周用茶树油漱口。每天（第1 - 4天）评估的菌斑指数（PI）作为临床对照参数。在研究的最后一天（第4天），对覆盖在前牙上的菌斑进行染色、拍照，并使用数字测量系统估算菌斑面积（PA；%）。在研究的每一天（第1 - 4天），使用活体荧光技术检查采集的菌斑。茶树油对临床参数（PI和PA）以及菌斑菌群的活力均无显著降低作用。在本研究设计的局限性范围内，确定将茶树油溶液用作普通漱口水对龈上菌斑的数量或质量没有积极影响。
