从没拔过牙，可小敏(化名)的嘴里只有12颗恒牙，正常人则应该有28-32颗。而且，她仅有的这些恒牙中，除了两颗门牙，剩下的都参差不齐，发育不良。如此严重的先天性牙缺失不仅导致她的嘴形内凹，还严重影响了她的容貌：年仅21岁的她，上半张脸看上去青春秀美，下半张脸却跟年迈的老太太一样。

Never pulled a tooth,Can XiaoMin(alias)Mouth only 12 a permanent teeth,Normal person should be have 28-32 star.and,She only in the permanent teeth,In addition to the two front teeth,The rest is uneven,dysplasia.So serious congenital anodontia not only led to her flat cove,Also seriously affected her appearance:She is only 21 years old,Half face looks beautiful youth,The second half but face with the old lady.

旧牙掉了，新牙却一直不长 Old teeth off,New tooth has been not long

　　小敏来自荆门，是武汉某高校的应届毕业生。据她自述，自己小时候换牙时，就跟同龄的小朋友不一样：乳牙掉了，新牙却迟迟不长。慢慢地，她的嘴里越来越空。经医生仔细检查，她口中“缺位”的恒牙多达18颗，其中6颗牙的位置仍由乳牙“占据”，但乳牙全都明显松动；在她仅拥有的12颗恒牙里，除了两颗门牙算得上发育正常，剩下的恒牙都“不合格”，要么歪歪斜斜，要么特别纤小。

XiaoMin from jingmen,Wuhan is a university graduate.According to her by,When I was a child when his restoration,Just like children their age is not the same:Milk teeth fall out,New tooth, lingering long.slowly,Her mouth is more and more empty.The doctor carefully examined,Her mouth"lack"The permanent teeth as many as 18 star,Six of the position of the tooth is still the primary teeth"occupy",But baby teeth loose all obvious;In her only have 12 star in the permanent teeth,In addition to the two front teeth is normal development,The rest of the permanent teeth are"The unqualified",Meanwhile or,Or special fine.

　　牙齿数量不到正常人的一半，小敏连吃饭都成了问题。长期以来，她只能吃松软的东西或流食，这间接导致她营养不良。

Less than half of the normal number of teeth,XiaoMin even eating has become a problem.For a long time,She can only eat soft thing or liquid,This indirectly led to her poor nutrition.

　　“9月初，她第一次来就医的时候，只见她年纪不大，面貌却像‘瘪嘴老太太’，人又瘦得厉害，非常可怜。”武汉大学人民医院口腔科主任雷志敏教授说，小敏的问题还远不止牙缺失，经检查，她还伴有颌面部上颌骨发育不足、下颌前突、牙冠磨耗严重、牙间隙大等问题。

"In early September,Her first time to go to a doctor of the time,See she is not that old,Appearance was like‘Nutcracker old lady’,People and thin badly,Very poor."Wuhan university people's hospital, director of the department of stomatology LeiZhiMin professor said,The problem of XiaoMin more than anodontia,Through inspection,She also accompanied by maxillofacial maxillary development shortage/Mandibular former process/Tooth crown abrasion serious/Tooth clearance of the problems.

　　姐弟4人，3人都有牙缺失

Elder sister and younger brother four people,Three people have anodontia

　　雷志敏教授询问后得知，小敏在家排行老三，有两个姐姐和一个弟弟。除了她的二姐外，大姐和弟弟也均有不同程度的牙齿先天缺失。据分析，小敏的父母为表兄妹，她们姐弟的牙齿缺陷，或许与父母为近亲结婚有关。

LeiZhiMin ask professor after that,XiaoMin ranking old three at home,Have two sisters and one brother.In addition to her two elder sister outside,Elder sister and younger brother also all have different degrees of congenital missing teeth.According to the analysis,XiaoMin parents for cousin,They asked teeth defect,Perhaps and parents to intermarry relevant.

　　小敏说，虽然牙齿问题常让她黯然神伤，但家里经济条件不好，她不想给家人增添负担，一直没有去就医。今年11月，她即将回到家乡工作，由于担心影响将来的工作和生活，这才决定上医院。

XiaoMin said,Although teeth problems often let her dejected,But home economic condition is bad,She doesn't want to add to the family burden,There has been no to go to a doctor.November,She was about to return home work,Because of fears that influence the future work and life,This just decided on hospital.

　　为了帮助小敏恢复成正常的模样，雷志敏教授与该科副主任张周文教授进行了详细探讨，征求了小敏的意见后，为她拔除了松动的乳牙和发育不良的恒牙，再对缺失的牙齿进行了套筒冠修复。经过近1个月的10余次治疗、修复，小敏嘴形正常了，也能吃普通的东西了。昨日，她带着青春的笑容顺利出院。(楚天都市报讯 记者 陈凌燕 通讯员 杨岑)
