Few studies have addressed the demographic characteristics of dental practice sites including endodontic practice sites. This study investigated the demographic characteristics of endodontic practice sites in the United States. Demographic data and endodontic practices were organized by zip codes and analyzed using discriminant analysis. The demographic characteristics associated with zip codes that contained an endodontic practice were determined versus the characteristics of zip codes that did not contain an endodontic practice. The resulting model correctly classified 93.7% of the 30,171 zip code areas based upon the presence or absence of an endodontic practice. The variables most closely associated with a zip code containing an endodontic practice included: number of dental practices (nonendodontic), population size, percent of adult population with a college degree, size of employed population, projected population growth (2005 to 2010), percent of population over 64 years old, and median housing value.
很少有研究探讨过包括牙髓治疗诊所地点在内的牙科诊所地点的人口统计学特征。本研究调查了美国牙髓治疗诊所地点的人口统计学特征。人口统计数据和牙髓治疗诊所按邮政编码进行整理，并使用判别分析进行分析。确定了包含牙髓治疗诊所的邮政编码所关联的人口统计学特征，并与不包含牙髓治疗诊所的邮政编码的特征进行对比。最终模型根据是否存在牙髓治疗诊所，正确分类了30171个邮政编码区域中的93.7%。与包含牙髓治疗诊所的邮政编码最密切相关的变量包括：牙科诊所（非牙髓治疗）数量、人口规模、拥有大学学位的成年人口百分比、就业人口规模、预计人口增长（2005年至2010年）、64岁以上人口百分比以及住房价值中位数。
