口腔扁平苔藓患者头发及唾液中 Fe,Zn,Cu,Mn,Ca,Mg,K 含量的检测研究

微量元素在人类的生命过程中是不可缺少的营养成分,在人体内发挥着特异的生理功能,。特别是在免疫功能及多种酶的合成方面都起着很重要的作用。大量的研究发现微量元素在人体内过多或过少都会引起疾患。近年来微量元素与口腔疾患之间的关系已开始受到关注,但     

Education, education, disillusion?

Between the end of 2009 and 2010, the General Dental Council (GDC) changed and the part appointed, part elected body which had been in place since its inception in 1957 became fully appointed. Since then, various quite radical departures in terms of its committee structure and proposals for the education and training of dental professionals have emerged. This paper reviews these developments in the wider context of the Council's role, recent record and overall accountability.     

Results of treatment of cancer of the lip

A study was carried out in Sancti Spiritus Province in the 1984-1986 period about the results of the treatment of lip cancer. Male patients were the most affected by lip cancer (CIE 8-140) in our series. The place of the tumor was predominantly the lower lip (p less than or equal to 0.001). Surgical treatment was used in 96.8% of the cases and the cuneiform (wedge-shaped) exeresis was the most commonly used method in the early stages of the disease (T1 y T2). Casta?ón keloplasty was the reconstructive procedure used in 18.7% of the patients. Local sepsis was present in 31.2% of the patients undergoing surgery, occurring most frequently in upper lip tumors.     

不同剂型玻璃离子水门汀溶解性比较研究

目的:研究、比较不同剂型玻璃离子水门汀的溶解性和表面微观形态改变,为临床使用提供依据.方法:将3M树脂加强型玻璃离子水门汀(水粉剂型)、GC玻璃离子水门汀(水粉剂型)及GC玻璃离子水门汀(双糊剂型)分别在人工唾液中浸泡30 d,冷热循环15000次,烘干测重,比较前后质量变化,计算溶解率,并用扫描电镜观察表面微观改变.结果:不同剂型的玻璃离子水门汀溶解率由高到低分别为3M树脂加强型玻璃离子水门汀(水粉剂型)、GC玻璃离子水门汀(水粉剂型)、GC玻璃离子水门汀(双糊剂型).3种玻璃离子水门汀经浸泡溶解后,SEM扫描表面微观形态可观察到GE玻璃离子水门汀(双糊剂型)表面形态改变较少,其他2组玻璃离子水门汀表面微观改变较多.结论:双糊剂型玻璃离子水门汀理化性能及溶解率均低于传统水粉剂型,是未来临床修复治疗的的良好选择.     

Evidence of the validity of a model of determinants of quality of restorative dental care

A model describing the relationship between self-reported quality of restorative dentistry and dentist characteristics for 119 Montana general dentists is presented. The best predictors formed a significant model explaining 22% of the variance of the quality measure. Results are contrasted with a previous estimation of the model for 102 Washington general practitioners. Evidence for the external validity of the model is presented.     

口底癌34例临床分析

目的探讨口底癌的临床特性、治疗方法及预后。方法对我院自1992—2002年住院治疗的34例口底癌患者进行回顾性分析。结果34例口底癌患者中,男28例(82.4%),女6例(17.6%),男女比为4.7∶1,平均发病年龄58岁。发病部位:前口底22例(64.7%),后口底12例(35.3%)。淋巴结转移率41.2%。单纯手术组、化疗加手术组、放疗加手术组、化疗加手术加放疗组的5年生存率分别为45.5%、60.0%、50.0%、62.5%。结论口底癌以中老年患者好发,男性居多。易发生淋巴结转移,综合疗法疗效较好。
