The purpose of this investigation was to determine the incidence of nutrient canals in a randomly selected population and to correlate the presence of nutrient canals with a variety of factors related to the life of the individual. One hundred sixty patients, 25 years of age or older, having at least six teeth in each arch and requiring a complete-mouth radiographic survey were used. Nutrient canals were found associated with race, high blood pressure, advanced periodontal conditions, multidirectional trabeculae, and small trabecular spaces.
本研究的目的是确定随机选择人群中滋养管的发生率，并将滋养管的存在与个体生活中的各种因素相关联。研究使用了160名年龄在25岁及以上、每侧牙弓至少有6颗牙齿且需要进行全口影像学检查的患者。发现滋养管与种族、高血压、晚期牙周状况、多方向小梁和小梁间隙小有关。
