The clinical and pathologic study of 17 cases of adenomatoid odontogenie tumor were presented. The average age is 17.8 year-old, and average duration 20.8 months with female in predominatce, In the majority of cases, the tumor is located in the anterior part of the maxilla or mandible. It is commonly associated with an unerupted tooth and may closely resemble a dentigenous cyst both radiographieally and at operation, but in some cases the presence of calcified material within the tumor may be a useful diagnostic...

The clinical and pathologic study of 17 cases of adenomatoid odontogenie tumor were presented. The average age is 17.8 year-old, and average duration 20.8 months with female in predominatce, In the majority of cases, the tumor is located in the anterior part of the maxilla or mandible. It is commonly associated with an unerupted tooth and may closely resemble a dentigenous cyst both radiographieally and at operation, but in some cases the presence of calcified material within the tumor may be a useful diagnostic feature.Histologically, tumor cells often resemble ameloblasts and are arranged in rosette-like or duct-like appearance. Acidophilic hyaline material is often demonsteated as dentine matrix with special stain.The adenomatoid odontogenic tumor is an epithelial odontogenic benign tumor with inductive changes in stroma and it is easily curable by enucleation.

本文报告17例牙源性腺样瘤,女性多见,平均年龄17.8岁,平均病期20.8个月。肿瘤多发生于颌骨前部。肿物常伴有未萌出的牙齿,在X线及手术中与含牙囊肿极为相似,而肿瘤内有钙化点为其诊断特点。组织学见肿瘤细胞常似造釉细胞排列成花瓣样和腺管样。嗜伊红均质样物质经特染证明似牙本质基质。因此认为牙源性腺样瘤是在间质中有诱导性变化的牙源性上皮性肿瘤。本瘤为良性肿瘤单纯刮治可治愈。

The purpose of this study was to search the effects of overdose fluoride on developed enamel in rat incisor. The histologic changes of enamel organ, ameloblasts and enamel were observed. The changes of enamel protein contents in the secretetory and maturation stage of enamel were investigated by using the techniques of bforheAnstry. The results demonstrated that secretatory ameloblasts formed some bubbles. The calcification of enamel was hetetogeneous.Enamel protein contents in secretatory stage...

The purpose of this study was to search the effects of overdose fluoride on developed enamel in rat incisor. The histologic changes of enamel organ, ameloblasts and enamel were observed. The changes of enamel protein contents in the secretetory and maturation stage of enamel were investigated by using the techniques of bforheAnstry. The results demonstrated that secretatory ameloblasts formed some bubbles. The calcification of enamel was hetetogeneous.Enamel protein contents in secretatory stage didn' t change signdicantly(P > 0. 05), in maturation stage increased (P < 0.01 ). All the results suggested that the development of ameloblasts was damaged due to the overdose fluoride.

为了探讨过量氟对鼠牙釉质发育的影响,本研究以大白鼠为实验动物,观察氟中毒后鼠牙造袖器、造釉细胞和釉质的组织形态学变化,并利用生化方法,检测氟中毒后釉质分泌期和成熟期釉质蛋白含量的变化。结果显示分泌期造釉细胞有空泡形成,釉基质钙化不均。分泌期釉质蛋白含量来见明显改变(P>005)。成熟期釉质蛋白含量增加(P<0.01)。表明氟中毒对鼠牙釉质造釉细胞形成过程可产生损害性影响。

Objective: To study the prevalence of enamel defects in the primary dentition of children with histories of low birth weight and premature birth. The risk factors of the enamel defects are also studied. Methods: The prevalence of primary enamel defects of one hundred and seventy six children (aged 3 8) with histories of low birth weight and premature birth (experimental group ) was studied and compared with a same aged group of 79 full term normal birth weight children (control group ). The method of stepwise regression analysis was used to analyse the important risk factors of primary enamel defects. Results: The prevalence of enamel defects in primary dentition of the experimental group was 77.3%, in which enamel opacity, enamel hypoplasia and combination lesions were 38.1%, 15.3%, 23.9%, respectively. This prevalence rate was significantly higher than 29.1% of the control group, in which enamel opacity, enamel hypoplasia and combination lesions were 12.7%, 11.4% , 5.1%, respectively. The important risk factors of enamel defects were in the following sequences: premature birth, damages by using laryngoscopy and orotracheal tube, multifetation, low birth weight, asphyxia of the newborn, hypocalcemia and prolonged labor. Conclusion: There is a high prevalence of enamel defects in the primary dentition of children with histories of low birth weight and premature birth. Various important risk factors influence corresponding ameloblasts in varying degrees.

目的:研究低出生体重儿和早产儿乳牙釉质发育缺陷的患病率及乳牙釉质发育缺陷的易感因素。方法:选择176名3~8岁的低出生体重儿和早产儿作为实验组,对照组为79名同龄的足月正常出生体重儿,比较2组乳牙釉质发育缺陷的患病状况,并用逐步回归的分析方法分析乳牙釉质发育缺陷的易感因素。结果:实验组不同类型釉质发育缺陷的患病率显著高于对照组,乳牙釉质发育缺陷的易感因素从强到弱依次为胎龄、出生后使用喉镜和气管插管、多胎、出生体重、新生儿窒息、低钙血症、产程延长。结论:低出生体重儿和早产儿好发乳牙釉质发育缺陷,出生时及出生后各种全身及局部因素均不同程度影响造釉细胞的正常生理功能,且这些因素还有协同作用
