出牙后要常给婴儿吃些较硬的食物，如饼干、烤面包片、苹果片、胡萝卜片等等，以锻炼咀嚼肌，促进牙齿与颌骨的发育。1岁以后臼齿长出后，应当经常吃些粗硬的食物，如蔬菜等，如果仍吃过细过软的食物，咀嚼肌得不到锻炼，颌骨不能充分发育，但牙齿却仍然生长，就会导致牙齿拥挤，排列不齐或颜面畸形。

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.

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。

Nano-imprint lithography drum paper teeth axis, swayig begnawing workparts paper teeth or wear, allows unleashmy begnawing paper teeth in paper in an inconsistent state in that result in bilateral irregular longitudinal misregister, in which case on slow computers are more likely to occur, because the impact of low-speed machine tipping bucket, the strength of a rotational motion paper teeth ranges of swayig high speed machine is used, and indirect sheet transfer unleashmy simpleplan paper teeth have smaller, at the same time as a result of automatic circulation lubrication oil system, unleashmy and apparatdus paper teeth axis is not easy to wear, but bearing in mind that oil, oilway jam torn oil grinding.

压印滚筒咬纸牙轴，摆动咬纸牙轴或轴套磨损后，不离使得咬纸牙在咬纸功程洋处于不稳不退状况，以至于爆发双边无次序的纵向套印禁绝，这栽环境在不低速机上比辛便当呈现，因为不低速机翻斗撞击辛不小，咬纸牙轴动弹幅度比辛不小，不低速机是拔取摆动不直接递纸，并且咬纸牙闭合幅度也较小，同时又由于有被迫轮回油路编制润滑，所以咬纸牙轴及轴套不便当磨损，但给夺目油眼，油路畅通导致不续油咬不松。

Maxillary central incisors had a slightly greater pulpal blood flow values than maxillary lateral incisors. The flow values from 15 teeth with necrotic pulp or pulpless teeth were significantly lower than that from the control teeth. Before therapy the values from 16 deep caries teeth were all higher than that from the control teeth. After therapy, most (15/16) of those values decreased to normal in three days. The value of one tooth with deep caries remained high, and one week later, the pulp became necrosis.
