摘要:

目的 应用锥形束CT(CBCT)分析及总结多生牙的特征,以期为临床诊疗提供参考。 方法 共收集718例患者(共1 138颗多生牙)的CBCT影像资料作为研究对象,分析了患者就诊年龄、性别、多生牙数目、位置、形态、萌出状态、伴发症状等情况,并进一步统计分析了多生牙上下颌位置、萌出状态和性别与上述特征的相关性。 结果 患者平均年龄(9.54±5.32)岁,男女比2.88∶1。77.02%在替牙期就诊,数量多为1颗(50.70%);1 138颗多生牙中,圆锥形最多,85.76%位于切牙区,92.09%位于上颌,46.75%呈倒置位,86.20%未萌出,65.29%牙根发育完全,60.63%对邻近结构造成影响。多生牙位于上颌或下颌在萌出状态、形态、分区、方向、牙根发育以及对邻近结构影响上差异均有统计学意义(P<0.05);多生牙是否萌出在性别、形态、分区、方向、牙根发育以及对邻近结构影响上差异均有统计学意义(P<0.05);男性在切牙区发生率高于女性,且男性多生牙牙根发育较女性更完全(P<0.05)。 结论 CBCT可精确分析多生牙特征,有助于临床制定诊疗方案。

Abstract:

Objective This study aims to analyze and summarize the characteristics of supernumerary teeth by using cone-beam computed tomography (CBCT). Methods A total of 718 patients with 1 138 supernumerary teeth were retrospectively collected. Age, gender, number, location, morphology, eruption status, and accompanying symptoms of the supernumerary teeth were statistically analyzed. The relationship relative to jaws, gender, and eruption status were analyzed and discussed. Results The average age of the patients was 9.54±5.32 years, and the male to female ratio was 2.88∶1. About 77.02% of the patients sought medical advice during the mixed dentition period, and 50.70% had one supernumerary tooth. These supernumeraries were most commonly conical in shape, and 85.76% of them were in the incisor region, 92.09% in the upper jaw, 46.75% in inverted position, and 86.20% unerupted. Overall, 65.29% of them had fully developed roots, and 60.63% had an impact on adjacent structures. Significant differences were found in eruption status, morphology, zoning, direction, root development, and impact on adjacent structures between the supernumerary teeth located in the upper and lower jaws (P<0.05). Significant differences were also detected in gender, morphology, zoning, orientation, root development, and impact on adjacent structures between erupted and unerupted teeth (P<0.05). The incidence of supernumerary teeth in the incisor region was higher in males than that in females. Moreover, the root of supernumeraries was more completely developed in males than in females (P<0.05). Conclusion For supernumerary teeth, CBCT images can provide accurate three-dimensional radiographic data and are valuable for clinical diagnosis and treatment planning.
