The occurrence of dental calculus is widespread with various investigators having reported evidence of calculus accumulations in a vast segment of the population. The purpose of this paper is to provide information on both the prevalence and incidence of calculus formation among adults. To determine prevalence, a total of 1,426 adult males and females were graded in Indiana for the presence of calculus using the Volpe-Manhold (VM) Index on the lingual surfaces of the six mandibular teeth. A second panel of 980 subjects was recruited in Texas to determine the incidence of calculus over a six-month period. These latter participants were given a thorough dental prophylaxis, a sufficient supply of a sodium fluoride dentifrice and toothbrushes, and were instructed to use the dentrifrice as they normally do, at least once a day. Six months after the prophylaxis, 804 participants were available and were examined for calculus accumulation using the VM Index. Results from both clinical trials indicate that males have more calculus than females and calculus formation was directly related to age for both sexes. Data are presented regarding the frequency distribution of VM Index scores by sex and age.
牙结石的出现非常普遍，许多研究人员都报告了在大量人群中存在牙结石堆积的证据。本文的目的是提供有关成年人牙结石形成的患病率和发病率的信息。为了确定患病率，在印第安纳州，使用Volpe-Manhold（VM）指数对1426名成年男性和女性下颌六颗牙齿舌面的牙结石情况进行分级。在德克萨斯州招募了980名受试者组成第二个小组，以确定六个月内牙结石的发病率。后一组参与者接受了全面的牙齿预防治疗，获得了足够的含氟牙膏和牙刷，并被指示按正常习惯每天至少使用一次牙膏。预防治疗六个月后，804名参与者接受检查，使用VM指数评估牙结石堆积情况。两项临床试验的结果均表明，男性的牙结石比女性多，并且牙结石形成与两性的年龄直接相关。文中给出了按性别和年龄划分的VM指数评分频率分布数据。
