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。

A simple estimation method for molar Gibbs free energy and enthalpy of formation for complex oxysalt minerals is proposed. Complex oxysalt minerals are divided into complex oxysalt minerals with water and complex oxysalt minerals without water. Complex oxysalt minerals without water can be considered as the composite of acidic oxides and alkaline oxides, so their molar Gibbs free energy or molar enthalpy of formation can be calculated by the summation of molar Gibbs free energy or molar enthalpy of formation of the acidic oxides and alkaline oxides which are combined into the complex compounds.
提出了一种复杂含氧盐矿物的摩尔生成Gibbs自由能和摩尔生成焓的简单估算方法,并把复杂含氧盐矿物分为不含水复杂含氧盐矿物和含水复杂含氧盐矿物,不含水复杂含氧盐矿物可以看作是酸性氧化物和碱性氧化物组成的物质,其摩尔生成Gibbs自由能或摩尔生成焓都可以看作是酸性氧化物和碱性氧化物复合成的化合物摩尔生成Gibbs自由能或摩尔生成焓之和。
