PURPOSE
The purpose of this study was to investigate the eruption of mandibular premolar teeth associated with dentigerous cysts.
PATIENTS AND METHODS
A total of 60 cyst-associated teeth in the mandibular premolars were examined retrospectively by using normalized panoramic radiographs. The subjects were divided into 2 groups: the erupted group, in which the teeth had erupted spontaneously after marsupialization, and the nonerupted group. Patient age, as well as impacted premolar angulation to the adjacent teeth axes, the cusp depth, space/tooth size, eruption period and cyst size, as measured on initial images, were used as parameters.
RESULTS
Using a logistic model of our data, we found that patient age less than 10 years, cusp depth less than 5.1 mm, angulations less than 25 degrees, and space/tooth size greater than 1.0 enhanced the success of eruption.
CONCLUSION
Our findings present predictors of successful eruption of impacted mandibular premolars associated with dentigerous cysts after marsupialization.
目的
本研究旨在调查与含牙囊肿相关的下颌前磨牙的萌出情况。
患者与方法
通过使用标准化全景X线片，对60颗下颌前磨牙中与囊肿相关的牙齿进行回顾性检查。研究对象分为两组：萌出组，即牙齿在袋形术治疗后自行萌出；未萌出组。将患者年龄以及在初始影像上测量的阻生前磨牙与相邻牙齿轴的角度、牙尖深度、间隙/牙齿大小、萌出期和囊肿大小作为参数。
结果
通过对我们的数据建立逻辑模型，我们发现患者年龄小于10岁、牙尖深度小于5.1毫米、角度小于25度以及间隙/牙齿大小大于1.0会提高萌出成功率。
结论
我们的研究结果提出了袋形术治疗后与含牙囊肿相关的阻生下颌前磨牙成功萌出的预测因素。
