Abstract

Multiple supernumerary teeth in the central incisor region are an uncommon occurrence; the most frequently occurring type of supernumerary teeth are mesiodens. A 10-year-old male had reported to Sharad Pawar Dental College with the chief complaint of extra teeth. An intraoral examination revealed the presence of two labially placed incisors and two palatally placed incisors at a transitional phase of dentition. During a radiographic examination, the maxillary occlusal view revealed four incisors with similar morphology. Extraction of the palatally placed incisor was done under local anaesthesia which was followed by alignment of the anterior teeth and closure of space. Supernumeraries that have erupted should always be removed, unless the teeth next to them are absent, in which case they should be left in place. After alignment, closure of spaces was done since the permanent canines had not yet erupted; it was decided against trying to completely close any gaps between the teeth.

摘要

中切牙区域出现多颗额外牙的情况并不常见；最常见的额外牙类型是正中牙。一名10岁男性前往沙拉德·帕瓦尔牙科学院就诊，主诉为多生牙。口腔检查发现，在牙列转换期有两颗唇侧位切牙和两颗腭侧位切牙。在进行影像学检查时，上颌咬合位片显示有四颗形态相似的切牙。在局部麻醉下拔除了腭侧位切牙，随后对前牙进行排齐并关闭间隙。已萌出的额外牙通常应予以拔除，除非其相邻的牙齿缺失，在这种情况下应保留额外牙。排齐后，由于恒牙尖牙尚未萌出，所以进行了间隙关闭；决定不试图完全关闭牙齿之间的任何间隙。
