Objective: To determine quantitatively the amount of demineralization and the ability of commercially available products and an experimental cream to inhibit or reverse orthodontic related demineralization.Methods: A total of 20 patients who were 25–35 years old and having orthodontic treatment for 6–8 months were chosen.Caries risk assessments were done for each patient and ones with “moderate risk” were included.Patients with fixed orthodontic appliances were divided into 4 groups(5 patients each) including one control and 3 study groups.All patients used same toothpaste 2 times a day during the 3 weeks study period.Additional to the toothpaste first study group used MI Paste Plus(GC, Tokyo, Japan), second study group used Remin Pro(Voco, Cuxhaven, Germany) and third group used an experimental remineralizing cream per day for 3 weeks.Maxillary central and lateral incisors of each patient were examined by FluoreCam(Daraza Therametric Technologies, USA) device.The examinations were performed at baseline and at the end of 1st, 2nd and 3rd weeks.Results: According to the FluoreCam measurements the control group showed significant amount of demineralization at the end of 3 weeks, moreover the amount of demineralization has gradually increased in time.At the end of the study all 3 study groups showed significant amount of remineralization and the amount of remineralization for all the 3 study groups has gradually increased in time.However the amount of remineralization for 3rd study group was lesser than the 1st and 2nd study groups.The remineralization amounts for the 1st and 2 nd study groups were determined to be identical.Conclusions: This study demonstrated that demineralization is measurable around orthodontic brackets and the demineralization can be completely inhibited and/or reversed by the use of commercially available remineralization products.

Maxillary central and lateral incisors of each patient were examined by FluoreCam (Daraza Thetrics Technologies, USA) device. examinations we re performed at baseline and at the end of 1st, 2nd and 3rd weeks. Results: According to the FluoreCam measurements the control group showed significant amount of demineralization at the end of 3 weeks, moreover the amount of demineralization has gradually increased in time.

Conclusions: This study demonstrates that demineralization is measurable around orthodontic brackets and the demineralization can be completely inhibited and / or reversed by the use of commercially available remineralization products.

经口进路茎突截短术视野受限,传统切取茎突的器具包括骨剪、骨钳或咬骨钳,除有时尚需修整茎突残存尖桩外,截骨时必须高度戒备断骨从夹持器械滑脱旧…。为了防止断骨滑脱,扁桃体圈套器已用于紧固粗硕的茎突切除段,采用不同型号的子宫刮匙分离茎突骨膜可改善手术视野。近来我们研制一种专门用于经口进路的手术器械,称之为茎突切除钳,现介绍如下。
一、教材分析  本节课是苏教版数学教材五年级上册的教学内容。这部分内容是以长方形的面积公式为基础,引导学生运用平移的方法,把平行四边形转化为长方形,进而得出平行四边形的面积公式,并应用公式解决相关的实际问题。  二、教学目标  1.通过实际操作和讨论思考,学生探索并掌握平行四边形的面积公式,能应用公式正确计算平行四边形的面积。  2.经历观察、操作、测量、填表、讨论、分析、归纳等数学过程,使学生进
