Regional odontodysplasia, or "ghost teeth," is a dental abnormality derived from both epithelial and mesenchymal components of the tooth bud. Teeth within a particular quadrant are affected. Affected teeth usually have thin enamel and dentin of poor quality with shortened roots, open apices, or enlarged pulp chambers. The permanent teeth and maxillary arch are observed to be more severely affected than primary teeth and the mandibular arch (ratio=1.6:1), respectively. Eruption of the affected teeth is delayed or may not happen. The cause of the phenomenon is unknown. Since this problem affects both dentitions and can involve multiple care disciplines, patients often require oral care over a long period of time. The purpose of this report was to present the management of a case from initial presentation at the age of 20 months to a final prosthesis completion at the age of 22 years. The long-term treatment may involve a pediatric dentist, orthodontist, oral surgeon, and prosthodontist.
局部牙发育异常,即“幽灵牙”,是一种源于牙胚上皮和间充质成分的牙齿异常。特定象限内的牙齿会受到影响。患牙通常釉质薄且牙本质质量差,牙根短、根尖开口或牙髓腔扩大。观察到恒牙列和上颌牙弓比乳牙列和下颌牙弓受影响更严重(比例为1.6:1)。患牙萌出延迟或可能无法萌出。该现象的原因尚不清楚。由于这个问题会影响两个牙列,且可能涉及多个护理学科,患者通常需要长期的口腔护理。本报告的目的是介绍一例从20个月初次就诊到22岁最终完成修复的病例管理情况。长期治疗可能需要儿科牙医、正畸医生、口腔外科医生和修复医生的参与。
