The clinical characters of oligodontia concluded from this study are following:(1) There is significant difference that more teeth absent and more existent teeth anomalies in patients of oligodontia/S group than in patients of oligodontia/I group, and the peg-shaped upper lateral incisor is the most frequently affected teeth with shape anomaly.(2) Both of the two groups have no significant differences in number of teeth missing between maxilla and mandible as well as that between left and right side.(3) The distribution of teeth missing is bilateral symmetry in both groups, but the frequency of teeth lost are different: excluding the third molar, in oligodontia/I group, the lower second premolar is the most frequently congenitally missing tooth followed by the upper lateral incisor, while in oligodontia/S group, the most frequently missing teeth are mandibular canine and maxillary lateral incisor. Nevertheless, the first molars are the most stable teeth in both groups.(4) In oligodonita/I group, the mean mesiodistal dimensions of all type of existent teeth are significantly smaller than normal value. It is implied that oligodontia is not an isolated phenomenon, but is related to a complex of other dental changes.

对于口腔多个恒牙先天缺失的临床特点有以下初步结论：(1)综合征型先天缺牙患者较单纯型先天缺牙患者恒牙缺失数目更多，平均分别为23.9个和14.9个，且现存牙齿有更多的形态异常，分别为7／10例（70％）和6／22例（27.3％），其中最常见的是上颌侧切牙畸形；(2)两种类型的多个恒牙先天缺失患者的缺牙数目在上下颌及左右侧之间均无差别；(3)两种类型的多个恒牙先天缺失患者在缺失牙位上均呈对称分布，但在具体牙位上有所差异：不计第三磨牙，单纯型先天缺牙最常缺失的牙位是下颌第二双尖牙、其次为上颌侧切牙；而综合征型先天缺牙最常缺失的牙位是下颌尖牙和上颌侧切牙；无论何种情况，第一磨牙均为牙列中最稳定的牙齿；(4)在单纯型先天缺牙患者中，现存恒牙的牙冠宽度较国人正常值偏小，差异显著，提示牙齿形态与多个牙先天缺失有一定相关性。

Birth, the permanent teeth in the deciduous tooth germ had been under, with the exception of the first molar (ie, age 6 teeth) in the neonatal period has begun to calcification, the calcification of permanent teeth is carried out in infancy, Therefore, the infant not only to protect the deciduous teeth, but also in order to obtain a fit and lay the foundation for permanent teeth.

婴儿出生时，恒牙的牙胚就已在乳牙之下，除第一磨牙（即6龄牙）在新生儿时期已开始钙化外，一部分恒牙的钙化是在婴儿期进行的，因此，婴儿期不仅要保护好乳牙，还要为获得一副健美的恒牙奠定基础。

Firstly, we performed pulpotomy for posterior teeth and pulpectomy for anterior teeth. And the experiments were divided into four groups. In the first group, nothing was put in the pulp chamber or canals. In the second group, deciduous dental pulp stem cells of mini-pig with cultured medium were transplanted into the pulp chamber and pulp canals. In the third group, deciduous dental pulp stem cells of mini-pig with lovastatin were transplanted. In the fourth group, deciduous dental pulp stem cells of mini-pig with odontoblast induction medium were transplanted.

在动物实验中，我们将迷你猪乳牙的前牙作拔髓，后牙做断髓处理，各分成四组做实验，第一组不放任何细胞、第二组加入迷你猪乳牙牙髓干细胞和培养液、第三组加入迷你猪乳牙牙髓干细胞和lovastatin，第四组加入迷你猪乳牙牙髓干细胞和odontoblast induction medium，观察三个月后，以探讨其牙齿组织是否会再生。
