在健康牙龈的人类受试者中，将薄的透明塑料膜应用于上颌骨和下颌骨的前磨牙的颊面。将膜留在原位15、30、60、120和240分钟的时间段。在龈缘附近区域调查球形细菌、白细胞和上皮细胞的存在。结果表明，到15分钟时，球形细菌已经附着在人造牙齿表面上。在研究期间，微生物数量逐渐增加。在120和240分钟后观察到大量球菌和小菌落的形成。在观察期间还发现白细胞和上皮细胞数量增加。
In human subjects with healthy gingiva thin transparent plastic films were applied to the buccal surfaces of premolars in the upper and lower jaws. The films were left in place for peiods of 15, 30, 60, 120 and 240 minutes. The presence of coccoid bacteria, leukocytes and epithelial cells was investigated in an area adjacent to the gingival margin. The results showed that by 15 minutes coccoid bacteria had become attached to the artificial tooth surface. The number of microorganisms gradually increased during the time of the study. Large numbers of cocci and the formation of micro-colonies were observed after 120 and 240 minutes. Increasing numbers of leukocytes and epithelial cells were also found during the period of observation.
