PURPOSE
The purpose of this study was to investigate the utility of the width-to-length ratio for the differentiation of ameloblastomas and odontogenic keratocysts in the body of the mandible.
MATERIALS AND METHODS
This study retrospectively reviewed 9 patients with ameloblastomas and 9 patients with odontogenic keratocysts using cone-beam computed tomography. The width-to-length ratio was determined by measuring the ratio between the greatest buccolingual dimension and the greatest perpendicular anteroposterior dimension of the lesion on the axial view. One-way analysis of variance was used to examine the difference in the width-to-length ratio between the 2 types of lesions. Statistical significance was tested at <0.05.
RESULTS
Ameloblastomas showed a mean width-to-length ratio of 0.64, whereas odontogenic keratocysts showed a mean width-to-length ratio of 0.41. The cut-off value with which the 2 types of lesions were differentiated was 0.5. The width-to-length ratios of ameloblastomas were significantly higher than those of odontogenic keratocysts (<0.05).
CONCLUSION
The width-to-length ratio might be used to differentiate between ameloblastomas and odontogenic keratocysts.
目的
本研究旨在探讨宽长比在下颌骨体部成釉细胞瘤与牙源性角化囊肿鉴别诊断中的应用价值。
材料与方法
本研究采用锥形束计算机断层扫描对9例成釉细胞瘤患者和9例牙源性角化囊肿患者进行回顾性分析。宽长比通过在轴向视图上测量病变最大颊舌径与最大垂直前后径之间的比值来确定。采用单因素方差分析来检验两种病变宽长比的差异。统计学显著性检验设定为<0.05。
结果
成釉细胞瘤的平均宽长比为0.64，而牙源性角化囊肿的平均宽长比为0.41。两种病变鉴别的临界值为0.5。成釉细胞瘤的宽长比显著高于牙源性角化囊肿（<0.05）。
结论
宽长比可用于鉴别成釉细胞瘤和牙源性角化囊肿。
