UNASSIGNED: This retrospective study analyzed the odontomas based on examination of mainly panoramic radiographs and related radiographs of 1280 patients in the NTUCH. Chi-square test was used for trend analysis.
UNASSIGNED: Among 1280 patients (710 boys and 570 girls), a total of 16 patients with odontomas (10 boys and 6 girls) were identified. There were 14 compound and 2 complex odontomas. The mean age of the patients was 10.38 years with the majority of odontomas occurring in the first (37.5%) and second decade (62.5%) of life. Odontomas had a marked predilection for the mandible (56.25%) and for the anterior region of the jaws (75%), particularly for the anterior maxilla (43.75%). Ten odontomas (62.5%) were associated with the impacted corresponding permanent teeth. The sagittal position of odontomas and vertical relation of odontomas to the corresponding permanent teeth were significantly correlated with the eruption rate of corresponding permanent teeth (P < 0.05).
UNASSIGNED: The odontomas occur most commonly in male patients with a male to female ratio of 1.67:1. The incidence of odontomas in our 1280 patients is 1.25%. The age range of patients with odontomas is 6-17 years. The most frequent location of odontomas is the anterior maxillary region. Odontoma is frequently associated with an impacted corresponding permanent tooth.
UNASSIGNED:这项回顾性研究主要基于对NTUCH中1280例患者的全景X射线照片和相关X射线照片的检查,分析了牙瘤。趋势分析采用卡方检验。
未经评估:在1280名患者(710名男孩和570名女孩)中,共发现16例牙瘤患者(10名男孩和6名女孩)。有14个化合物和2个复杂的牙瘤。患者的平均年龄为10.38岁,大多数牙瘤发生在生命的第一个十年(37.5%)和第二个十年(62.5%)。牙瘤对下颌骨(56.25%)和颌骨前部(75%)有明显的好感,特别是前上颌骨(43.75%)。10个牙齿切除(62.5%)与受影响的相应恒牙有关。牙瘤的矢状位置和牙瘤与相应恒牙的垂直关系与相应恒牙的萌出率显着相关(P<0.05)。
UNASSIGNED:牙瘤最常见于男性患者,男女比例为1.67:1。在我们的1280例患者中,牙瘤的发生率为1.25%。牙瘤患者的年龄范围为6-17岁。牙瘤最常见的位置是上颌前区域。牙瘤经常与受影响的相应恒牙相关。
