Agenesis of maxillary lateral incisors and mandibular second premolars is the most frequent form of hypodontia. Its prevalence varies across population from 0.8% to 4.5%. Genetic aberrations and environmental factors may cause agenesis of one or more teeth. The management of child having such a problem is very important since diastema in teeth especially in upper anteriors not only affects child's physical appearance but also its psychological development as the child wants to look like other children. In this article is presented a case of non-syndromic agenesis of maxillary lateral incisors (MLIA) and mandibular central incisors in a 10-year-old boy (patient) in permanent dentition with its management along with the radiographic investigations and photographic presentations of the other members of his family affected with this condition.
上颌侧切牙和下颌第二前磨牙先天性缺失是缺牙症最常见的形式。其患病率在不同人群中有所不同，从0.8%到4.5%不等。遗传畸变和环境因素可能导致一颗或多颗牙齿先天性缺失。对患有此类问题的儿童进行治疗非常重要，因为牙齿间隙，尤其是上前牙的间隙，不仅会影响儿童的外貌，还会影响其心理发育，因为孩子希望自己看起来和其他孩子一样。本文介绍了一名10岁恒牙期男孩（患者）非综合征性上颌侧切牙（MLIA）和下颌中切牙先天性缺失的病例，及其治疗方法，同时还展示了其家族中其他受此病影响成员的影像学检查和照片资料。
