牙瘤被认为是错构瘤性病变,是颌骨两种最常见的牙源性肿瘤之一。牙瘤被分类为化合物或复合物。最近,成釉细胞纤维牙本质瘤(AFO)和成釉细胞纤维牙本质瘤被重新分类为发展中的牙本质瘤。尽管临床上的牙瘤通常无症状,它们对相邻的牙齿有不良影响,如牙齿嵌塞,延迟喷发,牙齿的位移,牙齿的过度保留,并可在颌骨内产生牙源性囊肿。我们试图通过收集和分析临床,射线照相,2013年至2022年在我院诊断的牙瘤病理资料。在这10年的时间里,242例患者的组织病理学和/或影像学诊断为牙瘤.没有性别偏爱,年龄在3至101岁之间(中位数,14年)。生命的第二个十年是最普遍的(57.4%)。没有下巴偏爱;然而,前颌是最常见的位置。94例(38.8%)有临床表现。最常见的发现是牙齿嵌塞(n=83)。9例(3.7%)经组织病理学证实与其他病变有关,例如牙质囊肿(n=8)和鼻腭管囊肿(n=1)。被诊断为与囊肿相关的牙瘤患者的中位年龄(25岁)比没有相关囊肿的牙瘤患者(14岁)大。与复杂和AFO相比,复合牙瘤是最常见的牙瘤类型,占71.4%,26.6%,2%,分别。大多数复合牙瘤涉及前颌(69.3%)和下颌骨(54.9%),而大多数复杂牙瘤涉及后颌(59.6%)和上颌骨(54.7%)。四个AFO位于后颌,75%涉及上颌骨。诊断为AFO的患者的中位年龄(12岁)与诊断为化合物(13岁)和复杂(16岁)的患者相比是最年轻的。总之,我们分析了临床,射线照相,242例新发牙瘤的病理特征。我们的研究重申,牙列瘤经常影响儿科人群,并可能破坏他们的牙列。根据这项研究的结果,我们的临床建议是防止牙瘤对相邻牙齿的问题是,牙医应易于诊断牙瘤,以确保及时通过手术切除牙瘤。
Odontomas are considered hamartomatous lesions and are one of the two most common odontogenic tumors of the jaw. Odontomas are classified as compound or complex. Recently, ameloblastic fibro-odontoma (AFO) and ameloblastic fibro-dentinoma were reclassified as developing odontomas. Though clinically odontomas are usually asymptomatic, they have adverse effects on adjacent teeth such as tooth impaction, delayed eruption, displacement of teeth, over-retention of teeth, and can give rise to odontogenic cysts within the jaw. We sought to evaluate the clinicoradiopathologic presentations of odontomas by collecting and analyzing the clinical, radiographic, and pathologic data of odontomas diagnosed in our institution from 2013 to 2022. Over this 10-year period, there were 242 patients with a histopathological and/or radiographic diagnosis of odontoma. There was no gender predilection and ages ranged from 3 to 101 years (median, 14 years). The second decade of life was the most prevalent (57.4%). There was no jaw predilection; however, the anterior jaw was the most common location. Ninety-four (38.8%) cases presented with clinical findings. The most common finding was tooth impaction (n = 83). Nine (3.7%) cases were histopathologically confirmed to be associated with other lesions such as dentigerous cysts (n = 8) and nasopalatine duct cyst (n = 1). The median age (25 years) of patients diagnosed with odontomas associated with cysts was older than patients with odontomas (14 years) without associated cysts. Compound odontomas were the most common type of odontoma compared to complex and AFOs with 71.4%, 26.6%, and 2%, respectively. The majority of compound odontomas involved the anterior jaw (69.3%) and mandible (54.9%) while the majority of complex odontomas involved the posterior jaw (59.6%) and maxilla (54.7%). The four AFOs were in the posterior jaw and 75% involved the maxilla. The median age (12 years) of patients diagnosed with AFO was the youngest compared to patients diagnosed with compound (13 years) and complex (16 years). In conclusion, we analyzed the clinical, radiographic, and pathologic features of 242 new cases of odontomas. Our
study reaffirms that odontomas frequently affect the pediatric population and can disrupt their dentition. Based on the result of this
study, our clinical recommendation to prevent problems to adjacent teeth from odontomas is for dentists to be apt in the diagnose of odontomas to ensure that they are surgically removed in a timely manner.
