The use of dentures has been associated with increased stimulated parotid salivary flow rates (SPFR). A comparison of SPFRs was made between dentulous subjects having 20+ teeth (n = 190) and edentulous individuals (n = 67). Two different populations were selected, a white group from the Baltimore Longitudinal Study of Aging and an African-American group from the Washington Village Medical Center in Baltimore. Each group was healthy and unmedicated and had a mean age of 70.2 years. SPFR was determined with a Carlson-Crittenden cup and 2% citrate for stimulation. The edentulous subjects did not wear their dentures during salivary collection. The results indicated a significantly lower SPFR in dentate individuals compared with edentulous subjects (p < 0.01). Dentulous men also had a lower SPFR than edentulous men (p < 0.04). In addition, a pre- and postsurgical evaluation of 10 individuals who underwent full mouth tooth extractions revealed no differences in SPFR. These results suggest that edentulism per se does not have a deleterious effect on stimulated parotid salivary flow rates.
佩戴假牙与刺激后的腮腺唾液流速（SPFR）增加有关。对有20颗及以上牙齿的有牙受试者（n = 190）和无牙个体（n = 67）的SPFR进行了比较。选取了两个不同的人群，一个是来自巴尔的摩纵向衰老研究的白人组，另一个是来自巴尔的摩华盛顿村医疗中心的非裔美国人组。每组均健康且未用药，平均年龄为70.2岁。使用卡尔森 - 克里滕登杯和2%柠檬酸盐进行刺激来测定SPFR。无牙受试者在唾液采集期间不佩戴假牙。结果表明，与无牙受试者相比，有牙个体的SPFR显著更低（p < 0.01）。有牙男性的SPFR也低于无牙男性（p < 0.04）。此外，对10名接受全口拔牙的个体进行的术前和术后评估显示，SPFR没有差异。这些结果表明，无牙本身对刺激后的腮腺唾液流速没有有害影响。
