Few data have been collected regarding the prevalence and quality of root canal therapy in American populations. European studies of various populations were used as a model for the evaluation of the prevalence and technical standard of endodontic treatment in a patient group seen for screening at a United States dental school. Full-mouth radiographic series were examined for the presence of root fillings, periapical pathologic conditions, and coronal restorative status. The obturation density and length were also recorded. Of 5272 teeth examined, 5.5% had root fillings. Periapical disease was evident in 4.1% of all teeth and 31.3% of root-filled teeth. Lesser-quality root fillings were more strongly associated with periapical disease than were higher-quality obturations. In addition, only 42% of the obturations could be considered technically satisfactory. Such data suggests that more research must be directed toward the study of factors that affect treatment outcome.
关于美国人群根管治疗的患病率和质量，收集到的数据很少。欧洲针对不同人群的研究被用作模型，以评估在美国一所牙科学校接受筛查的患者群体中牙髓治疗的患病率和技术标准。对全口X线片系列进行检查，以确定是否存在根充物、根尖周病理状况和冠部修复状况。还记录了根充的密度和长度。在检查的5272颗牙齿中，5.5%有根充物。根尖周疾病在所有牙齿中占4.1%，在已进行根充的牙齿中占31.3%。质量较差的根充物比质量较高的根充物与根尖周疾病的关联更强。此外，只有42%的根充在技术上可被认为是令人满意的。这些数据表明，必须针对影响治疗结果的因素开展更多研究。
