A comparative study of four classical techniques employed in the sampling of subgingival microflora (paper points, swabbing, curette and washing followed by aspiration) has been carried out. This study was based upon quantitative criteria (number of bacteria sampled) and qualitative criteria (number of morphologically distinct colonies found per sampling technique). Sampling was done on three different groups of patients: a control group, a group of patients with gingivitis and a group of patients with periodontitis. The curette sampling technique was found to be efficient both quantitatively and qualitatively. Difficulties in standardizing this method however were encountered with the failure to achieve reproducible results. For this reason the technique of paper point was preferred. This method was found to be more reliable and reproducible in each of the three groups of patients sampled.
已对用于龈下微生物群采样的四种经典技术（纸尖法、擦拭法、刮治法以及冲洗后抽吸法）进行了比较研究。本研究基于定量标准（采样的细菌数量）和定性标准（每种采样技术发现的形态学上不同的菌落数量）。对三组不同的患者进行了采样：一个对照组、一组牙龈炎患者和一组牙周炎患者。发现刮治采样技术在定量和定性方面均有效。然而，在标准化该方法时遇到了困难，未能获得可重复的结果。因此，纸尖法更受青睐。在对三组患者中的每一组进行采样时，发现该方法更可靠且可重复。
