Thirty patients (19 men and 11 women) were provided with a removable partial denture (RPD) and assigned randomly to two groups: 15 patients were called back twice a year for plaque control, reinforcement of instructions, denture hygiene control and professional prophylaxis; the other 15 were not called back. The 30 patients were examined after 2-3 weeks following the end of the prosthetic treatment, after 1 and 2 years. At each examination, the following parameters were recorded [gingival inflammation, plaque index (Pl I), tooth mobility, attachment level, pocket depth] and a bacteriological examination of subgingival plaque was carried out. Few differences appeared between the two groups; the values observed show a relatively low level of hygiene and but little motivation with regard to prophylaxis techniques.
30名患者（19名男性和11名女性）佩戴了可摘局部义齿（RPD），并随机分为两组：15名患者每年被召回两次，进行菌斑控制、强化指导、义齿卫生控制和专业预防；另外15名患者未被召回。在修复治疗结束后2至3周、1年和2年后对这30名患者进行检查。每次检查时，记录以下参数[牙龈炎症、菌斑指数（Pl I）、牙齿松动度、附着水平、牙周袋深度]，并对龈下菌斑进行细菌学检查。两组之间几乎没有差异；观察到的值显示卫生水平相对较低，且对预防技术的积极性不高。
