The aim of this study was to characterize dental anomalies. The pretreatment records (photographs and radiographs) of 2897 patients (41.4% males and 58.6% females) were utilized to detect dental anomalies. The dental anomalies studied were related to number, size and shape, position, and eruption. A Chi-square test was carried out to detect associations between dental anomalies, jaw, and sex. A total of 1041 (36%) of the subjects manifested at least one dental anomaly. The prevalence of all dental anomalies was jaw-dependent and greater in the maxilla, except for submerged and transmigrated teeth. The most frequently missing teeth were the maxillary lateral incisor (62.3%) and the mandibular second premolars (60.6%). The most frequent supernumerary teeth were the incisors in the maxilla (97%) and the first premolars in the mandible (43%). Dental anomalies are more frequent in the maxilla and mainly involve the anterior teeth; in the mandible, however, it is the posterior teeth. These differences can be attributed to the evolutionary history of the jaws and their diverse development patterns.
本研究的目的是对牙齿异常进行特征描述。利用2897例患者（41.4%为男性，58.6%为女性）的治疗前记录（照片和X光片）来检测牙齿异常。所研究的牙齿异常与数量、大小和形状、位置以及萌出有关。进行了卡方检验以检测牙齿异常、颌骨和性别之间的关联。共有1041名（36%）受试者表现出至少一种牙齿异常。除了埋伏牙和移位牙外，所有牙齿异常的患病率均与颌骨有关，且在上颌中更高。最常缺失的牙齿是上颌侧切牙（62.3%）和下颌第二前磨牙（60.6%）。最常见的多生牙是上颌切牙（97%）和下颌第一前磨牙（43%）。牙齿异常在上颌中更常见，主要累及前牙；然而，在下颌中则是后牙。这些差异可归因于颌骨的进化历史及其不同的发育模式。
