4. RED SURFACES / RED LEAD
6. DUST SCREENING
“Bleeding” may occur when testing surface is painted red. However the color that rubs off a surface is often visibly different from the pink to red color that develops when a 3M™ LeadCheck™ Swab detects lead. The easiest way to test for bleeding is to CRUSH VIAL “B” ONLY, and bring a drop of the clear colorless fluid to the tip of the swab. Rub the tip of the swab on the surface. Any color that appears on the tip has “bled” from the test surface and may make reading the test results difficult.
DISCLAIMER
3M™ LeadCheck™ Swabs is a screening test for lead and should not be considered quantitative. Under controlled laboratory conditions, 3M™ LeadCheck™ Swabs will indicate the presence of lead as low as 1-2 micrograms. Under the conditions described in the instructions, 3M™ LeadCheck™ Swabs will detect high levels of leachable lead. Use of this test is not intended to replace a professional inspection. No guarantees are intended or implied.

Designing with 3M Dual Lock Reclosable FastenersSubstrate attachment & surface preparation3M™ Dual Lock™ Reclosable Fastener is attached to substrates through various means; the most prevalent is with pressure sensitive adhesive tapes pre-applied to the 3M Dual Lock Reclosable Fastener backing. The pressure sensitive adhesive tape requires a clean dry surface and firm even pressure (15psi) to ensure good contact with the surface of the substrate to which it is being applied.Most 3M Dual Lock Reclosable Fastener products will adhere best to high surface energy substrates, such as metals (like stainless steel, aluminum) or medium surface energy substrates (like ABS, polycarbonate, and acrylic). For low surfaceenergy substrates (like powder coated paint and other plastics), consider advance treatment of the surface with 3M™ T ape Primer 94 or 3M™ VHB™ T ape Universal Primer UV which will increase adhesion to many low surface energy substrates. Please refer to the 3M Dual Lock Reclosable Fasteners with Acrylic Foam T ape Application Guide for more information.Technical BulletinTemperature and environmental exposure3M™ Dual Lock™ Reclosable Fastener is designed to be applied between 68-80°F (20-27°C). For long term use in high temperatures or outdoor conditions please consider the following guidelines for temperature resistance:• SJ3560/61/62 220F (104°C• SJ3550/51/52 200F (93°C)• Other 3M Adhesive-backed products and non-adhesive backed products are available, including:• Piece parts: rigid backed 3M Dual Lock Reclosable Fastener pieces designed to be mechanically fastened to substrates • Low profile 3M Dual Lock Reclosable Fastener: minimal engaged thickness and reduced weight limit • Hook & loop: for applicationsFor more information on piece parts and other 3M Reclosable Fasteners, please contact your 3M Representative or 3MTechnical Service.Engagement and disengagement strengthIn one square inch there are approximately 170, 250 or 400 stems. • To achieve the desired attachment strength, start the evaluation with 250 to 250.• To increase the attachment strength, evaluate 250 to 400. • To decrease the attachment strength, evaluate 170 to 250.Note: If 250:250 is the correct strength but difficult to engage, we recommend evaluating 170:400.Note: We advise against 170:170 because the attachment will be very weak. We advise against 400:400 because you may not be able to engage the two sides completely or disengage them without damage.• SJ3870/71/72 158F (70°C)• SJ3540/41/42 120F (49°C)Design considerationsThe performance of 3M™ Dual Lock™ Reclosable Fastener depends on the design of the final assembly. The suggested starting point for evaluation is starting with four square inches (4 in2) of fastener area per pound of static tensile or shear load to be supported, increasing or decreasing the amount of fastener may be needed depending on the substrates and application, this should be tested in the specific application.Suggestions•Use 4 square inches of 3M™ Dual Lock™ Reclosable Fasteners per pound of dead load •Apply to a clean dry surface•Apply firm even pressure of at least 15 pounds per square inch•Apply the 3M Dual Lock Reclosable Fastener between 68-80°F (20-27°C)This technical bulletin is not a substitute for performance testing and should be used to identify the appropriate 3M Dual Lock Reclosable Fastener to begin your evaluation.Industrial Adhesives and Tapes Division 3M Center, Building 225-3S-06St. Paul, MN 55144 USA Phone 1-800-362-3550Web /DualLock© 3M 2019.

不锈钢预制临时牙冠Stainless Steel Crowns 产品中文产品中文使用说明书使用说明书适用范围：适用于3M 生产的所有不锈钢预置临时牙冠规格型号：见外包装成人及儿童不锈钢预制临时牙冠由3M ESPE 生产的成人及儿童不锈钢预制临时牙冠，适用于成人磨牙，双尖牙和儿童前后牙，是较长期的暂时冠。

3M ESPE 有两种不同的不锈钢预制临时牙冠边缘，以便适合于牙科医生的特殊需求。

不锈钢预制临时牙冠是预先成形，邻面呈鼓型，边缘内收。

这样在试戴牙冠时可以最小限度地修整边缘。

不锈钢预制临时牙冠经过淬火处理，所以更加坚硬，而龈缘较薄，这样牙冠边缘与预备体可以更加贴合。

不需要调整时牙冠不需要调整时牙冠的粘固的粘固1． 用测量尺在病人口腔内测量缺牙间隙近远中径，然后选择合适大小的牙冠。

建立正确的毫米数，测量套装内牙冠尺寸，以便挑选出合适的牙冠。

2． 和牙体预备前的测量数据比较，最后确认牙冠尺寸。

3． 试戴试戴。

把挑选的牙冠轻轻滑动到预备好的牙齿上，记录下牙冠与邻牙及对合牙的接触关系，为方便就位，戴下颌牙冠从舌側向颊側，戴上颌牙冠从颊側向舌側。

就位后，用探针检查牙冠与预备体之间是否有缝，如有必要可以修剪牙冠边缘。

4． 检查咬合检查咬合。

摘下牙冠，再次检查上下牙咬合关系。

如果牙冠妨碍了牙列的正常咬合关系，则需要重新预备患牙，以便试戴后有正常的咬合关系。

选定Unitek 牙冠后，牙冠边缘需要修整以使牙冠顺利就位。

5． 隔离患牙隔离患牙。

冲洗患牙区，用棉卷隔湿，彻底吹干。

6． 调水门汀调水门汀，，粘固牙冠粘固牙冠。

根据生产商的提示调拌水门汀，要防止空气进入。

7． 把牙冠戴到预备体上把牙冠戴到预备体上。

和第3步相同，牙冠就位后多余的水门汀会被挤压出去。

注意注意：最后就位时，不要用大拇指加太大压力。

8． 迅速检查牙冠与邻牙接触区及咬合。

9． 让病人咬合牙冠让病人咬合牙冠。

病人咬合应该在正常的自然的咬合力下，如果用棉卷等其他方法增加 咬合力分布，要切记尽可能放置在缺牙间隙近远中径。

树脂粘固剂商品名商品名：：RelyX ARCAdhesive Resin Cement产品中文产品中文使用说明书使用说明书适用范围：适用于3M 生产的树脂粘固剂(RelyX ARC)规格型号：初始装、补充装说明树脂粘固剂是一种永久粘结用的双固化树脂粘固剂，它是独特的双糊剂自动混配系统。

它可以用于以下修复体的永久粘结：• 金属烤瓷冠和桥• 金属冠，桥，嵌体，高嵌体，（贵金属，普通金属合金）• 冠和桥与少量牙体组织的粘结• 马里兰桥（树脂粘合的桥）• 所有陶/瓷和预先处理过的合成物冠，桥，嵌体和高嵌体• 根管桩• 银汞修复体的粘结• 注意：间接贴面的粘结，应将3M 生产的RelyX Veneer 与SingleBond 2 粘结剂或 Adper Schotch bond 多功能粘结剂联合使用。

•建议建议用光固化边缘区域以提供最大强度和抗磨损力。

光固化时间应使用3M 光固化灯或其它的强度相当的牙科光固化灯。

光固化灯应该经常用一个可靠的光计量系统检查以保证适当的输出强度。

粘合操作中使用的空气必须没有油和水的污染。

用塑料混合抹刀或一个高质量的不锈钢混合树脂粘固剂。

临时冠的粘结剂应不含无丁香油。

操作时间和凝固操作时间和凝固时间时间时间：：光固化***混合时间 操作时间* 去除粘结剂时间** 光固化每边缘 @ 22℃/72℉ @ 22℃/72℉ @35℃/94℉ 40秒（室温） (-)2分 口内温度 或10秒 固化后～3-5分 自固化从混合开始后10分* 如果要延长操作时间：混合10秒（调和时间越长，固化时间越短），将树脂粘固剂在混合垫上展开成薄层，冷却调和垫，调刀或假牙。

** 如果在定位后立即从缘移走过多的树脂粘固剂，则边缘必须进行光固化以使会导致较差密封边缘的氧气抑制达到最小。

对于牙体组织剩余少的修复体（最小牙结构的冠和桥），在清洁时应定位和保持修复在适当位置。

*** 半透明修复每边缘表面必须光处理40秒。

一步一步做好预成冠后牙一、适应症1龋坏大面积龋坏或者临面龋坏。

2牙髓治疗之后。

3预防性修复V还没有IV已经坏的这么厉害，与其补起来但可能继发龋，不如使用预成冠隔绝起来。

4间隙保持器的固位体。

5发育或者生长缺陷6年轻恒牙的半永久修复二、禁忌症1不能配合的儿童2形态异常或者缺损面积过大，导致没有足够的固位3X片显示乳磨牙牙根吸收超过1/24对金属过敏皮疹三、术前评估和材料准备评估内容：1、孩子的牙龄（是否还有必要）2、安全的问题（孩子是否配合）为了安全最好在橡皮障下操作。

生理或者心理缺陷材料：初试套装金冠剪缩口钳金属磨头橡皮障临面钳快机常用牙号：下颌4号5号上颌5号6号四、牙体初步预备一般颌面1mm就够，而且大部分牙齿的颌面龋坏严重，并不需要严格预备。

临面预备根据情况，如果有比较大的生长间隙，就不需要预备。

圆滑轴角。

即使第一恒磨牙未萌出，V的远中也要预备，防止6阻生。

（预备的时候放楔子，防止损伤6的近中临面）一定不能有肩台，有肩台会就为困难。

五、选冠和试戴选冠方法：1测量法。

2直接试戴法。

宜小不宜大。

就位置角度：下颌先就位舌测，上颌先就位颊侧。

六、针对性牙体预备常见的就位阻碍为下颌颊侧隆突。

七、冠的修剪和成形边缘长的表现：就位后边缘发白，出血，咬合高，咬合痛。

冠的自带边缘就是按照牙龈的走形，所以修剪边缘注意按照冠的边缘平行修剪，要整个一圈都剪掉，不能哪里长减哪里。

一般最多修剪0.5-1mm。

（如果使用临面缩紧钳导致的边缘过长，可以只修剪一部分）逆时针，连续修剪，注意支点，因为冠只有0.2mm，很容易修剪，但修剪后容易变形，需要使用边缘缩紧钳重新成形。

八、抛光、粘接抛光：要求不高，主要是把修剪边缘的毛刺平滑一下，用手指感受不要有毛刺。

清洁：酒精清洁。

粘接：粘接剂要够多，满。

可以使用玻璃离子，也可以为了操作时间短可以使用双固化。

注意隔湿。

九、常见问题：就位不好的可以使用邻面调整钳缩短近远中径。

特别是做连冠。

Air1. 胶带,底胶的选择不当-根据不同的粘结表面选择合适的胶和底胶；-标准胶带对汽车油漆表面有优越的粘结力。

-若要粘附塑料，为获得满意的粘结效果，使用底胶是必要的。

2. 没有消除部件表面的可塑剂-部件（特别是软PVC 部件）表面的增塑剂能降低粘结的效果。

3. 低温-丙烯酸泡绵胶带是由有机高分子聚合物制成，因此在低温状态下会变硬而失去粘性-当作业环境温度低于15度时，推荐加热车身和要粘结的部件。

4. 低压力-胶带是没有流动性的，施加适当的压力才能获得足够的浸润面积。

5. 粘结表面污染-部件和胶面污染都会引起粘结失败。

-推荐使用恰当的溶剂清洗粘结表面。

不锈钢预制临时牙冠Stainless Steel Crowns 产品中文产品中文使用说明书使用说明书适用范围：适用于3M 生产的所有不锈钢预置临时牙冠规格型号：见外包装成人及儿童不锈钢预制临时牙冠由3M ESPE 生产的成人及儿童不锈钢预制临时牙冠，适用于成人磨牙，双尖牙和儿童前后牙，是较长期的暂时冠。

3M ESPE 有两种不同的不锈钢预制临时牙冠边缘，以便适合于牙科医生的特殊需求。

不锈钢预制临时牙冠是预先成形，邻面呈鼓型，边缘内收。

这样在试戴牙冠时可以最小限度地修整边缘。

不锈钢预制临时牙冠经过淬火处理，所以更加坚硬，而龈缘较薄，这样牙冠边缘与预备体可以更加贴合。

不需要调整时牙冠不需要调整时牙冠的粘固的粘固1． 用测量尺在病人口腔内测量缺牙间隙近远中径，然后选择合适大小的牙冠。

建立正确的毫米数，测量套装内牙冠尺寸，以便挑选出合适的牙冠。

2． 和牙体预备前的测量数据比较，最后确认牙冠尺寸。

3． 试戴试戴。

把挑选的牙冠轻轻滑动到预备好的牙齿上，记录下牙冠与邻牙及对合牙的接触关系，为方便就位，戴下颌牙冠从舌側向颊側，戴上颌牙冠从颊側向舌側。

就位后，用探针检查牙冠与预备体之间是否有缝，如有必要可以修剪牙冠边缘。

4． 检查咬合检查咬合。

摘下牙冠，再次检查上下牙咬合关系。

如果牙冠妨碍了牙列的正常咬合关系，则需要重新预备患牙，以便试戴后有正常的咬合关系。

选定Unitek 牙冠后，牙冠边缘需要修整以使牙冠顺利就位。

5． 隔离患牙隔离患牙。

冲洗患牙区，用棉卷隔湿，彻底吹干。

6． 调水门汀调水门汀，，粘固牙冠粘固牙冠。

根据生产商的提示调拌水门汀，要防止空气进入。

7． 把牙冠戴到预备体上把牙冠戴到预备体上。

和第3步相同，牙冠就位后多余的水门汀会被挤压出去。

注意注意：最后就位时，不要用大拇指加太大压力。

8． 迅速检查牙冠与邻牙接触区及咬合。

9． 让病人咬合牙冠让病人咬合牙冠。

病人咬合应该在正常的自然的咬合力下，如果用棉卷等其他方法增加 咬合力分布，要切记尽可能放置在缺牙间隙近远中径。

医院儿童牙病护理常规由于儿童的解剖、生理、病理和就诊心理及行为等特点，使儿童牙病的护理有别于成人，只有充分了解儿童的特殊性，才能更好、更主动地做好儿童牙病的护理工作。

一、诊疗行为诱导到儿童牙科来就诊的患儿，大多有不同程度的恐惧感，尤其以幼儿期和学龄前期儿童多见。

表现为害怕、紧张、哭闹；不愿与医护人员交谈，不愿接受甚至拒绝治疗，消除这些不利的诊疗行为，达到完成诊疗目标的方法就是诊疗行为诱导。

这项诱导工作通常由护理人员完成，所以这也是儿童牙科特别的一项护理工作。

（一）一般患儿的诊疗行为诱导1.环境感化法：营造适合儿童特点的诊疗环境，可以减轻患儿的恐惧心理。

2. 言语交流法：要避免成人化和专业化，采用简单易懂、具体形象的形体语言和童语，而不是生硬的、命令式的语言。

例如把水枪比作淋浴器，告诉患儿这是用来给牙齿洗澡的；把气枪比作电风扇是给牙齿吹风的；把拍片检查说成是给牙齿照张相片等。

3.鼓励为主法：因患儿情感发育的特点，在口腔治疗中，出现不配合的行为是很自然的。

因此应以鼓励为主，批评为辅，交替使用来诱导患儿，对患儿的每一点进步都要及时给予表扬和鼓励。

4.适应法：许多患儿在接受口腔治疗时，由于初次接触医院的特殊环境，听到或感受到牙钻的转动声，金属器械的碰撞声，容易产生恐惧心理，可先让患儿用手摸一摸口镜、探针等诊疗器械，消除其恐惧心理后才开始检查患牙。

牙钻的试验体会：先开机，让患儿熟悉声音和喷水状况，示意患儿不会产生疼痛，最后在口内患牙上制洞，应稳、准、轻、快地完成治疗工作。

5.短时操作法：儿童生性好动，固定于某一姿势的持续时间短，操作时间宜短不宜长，尽量在短时间内完成治疗工作。

6.参观学习法：对胆小或有恐惧症的患儿，治疗前可让其参观正在接受治疗的其他小朋友的治疗情况，再让合作儿童讲述自己的诊疗感受和体会，这样可增强自己治牙的勇气，达到消除恐惧，接受治疗的目的。

（二）不合作患儿的诊疗行为诱导不合作患儿的诊疗行为诱导方法主要有3种，即固定法、镇静法和全身麻醉法。

InterpretationGuideThe 3M™ Petrifilm™ Coliform Count Plateis a sample-ready-culture medium system which contains modified Violet Red Bile nutrients, a cold-water-soluble gelling agent and a tetrazolium indicator that facilitates colony enumeration.2Coliform Count PlateTotal colonies with gas = 69 Total colonies = 94The definition of coliforms may vary by country. Please refer to section above and product instructions for definitions.Figure 1No growth = 0Notice the changes in gel color in Figures 2–5. As the coliform count increases, the gel color deepens.Background bubbles are a characteristic of the gel and are not a result of coliform growth.Figure 2The United States Food and Drug Administration (FDA) Bacteriological Analytical Manual (BAM) defines coliforms as Gram negative rods, which produce acid and gas from lactose fermentation. Coliform colonies growing on the 3M ™ Petrifilm ™ Coliform Count Plate produce acid, which causes the pH indicator to deepen the gel color, and gas trapped around red colonies. In this interpretation guide, the number of coliforms per the FDA BAM definition is the number of red colonies with gas.ISO defines coliforms by their ability to grow in method-specific, selective media. ISO method 4832 enumerates typical coliform colonies on Violet Red Bile Lactose (VRBL) agar, with confirmation of atypical colonies. On the 3M Petrifilm Coliform Count Plate, these coliforms are indicated by red colonies with or without gas production. ISO method 4831, enumerating coliforms by the most probable number (MPN) method, defines coliforms by their ability to grow and produce gas in the conditions described in the standard. On the 3M Petrifilm Coliform Count Plate, these coliforms are indicated by red colonies with gas.It is also possible to enumerate thermotolerant coliforms on the 3M Petrifilm Coliform Count Plate. Typically thermotolerant coliforms can be selected with an elevated incubation temperature. One example of a method for enumeration of thermotolerant coliforms is described in NF V08 060. Reading the total of red colonies on a 3M Petrifilm Coliform Count Plate incubated at 44°C ± 1°C for 24h ± 2h yields results equivalent to enumeration with NF V08 060.Coliform Definitions by MethodFood and Beverage ApplicationsPlease refer to theproduct instructions for additional information.3Total colonies with gas = 79 Total colonies = 109The recommended counting limit on 3M Petrifilm Coliform Count Plates is less than 150.Do not count colonies that appear on the foam barrier because they are removed from the selective influence of the medium (see Circle 1).1Figure 3Total coliform count = TNTC3M Petrifilm Coliform Count Plates with colonies that are too numerous to count (TNTC) have one or more of the following characteristics: many small colonies, many gas bubbles, and a deepening of the gel color.For a more accurate count, further dilution of sample may be necessary.Figure 5Estimated total coliform count = 220The circular growth area is approximately 20cm 2. Estimates can be made on plates containing greater than 150 colonies by counting the number of colonies in one or more representative squares and determining the average number per square. Multiply the average number by 20 to determine the estimated count per plate. For a more accurate count, further dilution of sample may be necessary.Figure 4Total count = TNTCWhen high numbers of non-coliform organisms such as Pseudomona s are present on 3M Petrifilm Coliform Count Plates, the gel may turn yellow.For a more accurate count, further dilution of sample may be necessary.Figure 64Total colonies with gas = 2 Total colonies = 2Food particles are irregularly shaped and are not associated with gas bubbles.Figure 7Total colonies with gas = 8 Total colonies = 15Bubble patterns may vary. Gas may disrupt the colony so that the colony “outlines” the bubble (see Circles 1 and 2). Artifact bubbles may result from improper inoculation or from trapped air within the sample. They are irregularly shaped and are not associated with a colony (see Circle 3).123Figure 8Bottled Water ApplicationsColiform colonies are indicated by red colonies associated with gas for bottled water samples plated to 3M Petrifilm Coliform Count Plates.Coliform count: 0Gas bubbles surrounding filter do not indicate microbial growth. See circle for example.Figure 1Coliform count: 0Red colonies without closely associated gas bubbles may be coliforms and should be picked and tested with appropriate confirmation methods.Figure 25Coliform count: 10Figure 4Coliform count: 3Coliforms produce acid (faint pink halo associated with colonies) and are associated with gas bubbles.Figure 3ABCColiform count: 30Gas bubbles may influence colony morphologies. The colony in Circle A is distorted by the gas bubble. In Circle B, a faint colony is underneath the gas bubble. Note large artifact gas bubble in the center of the plate (Circle C).Figure 5Store unopened pouches of plates at<8°C (<46°F). Use before expiration dateon package.

乳磨牙预成冠的临床进展摘要】目的：本文详细地分析了小儿乳磨牙大面积缺损后，利于预成冠进行修复的临床效果分析，并对其疗效进行系统评价。

方法：选自我院于2016年1月-2015年6月期间口腔科收治的42例小儿乳牙龋坏患者，随机分为观察组和对照组，观察组采用树脂充填后预成冠修复，对照组则采用树脂充填治疗。

分别对两组乳磨牙治疗后的6个月，一年，2年的疗效进行系统的评估。

结果：观察组21例患者在6月修复体的脱落率为0，一年的脱落率为4.76%，2年的脱落率为9.52 %，对照组21例患者在6月修复体的脱落率为4.76%，一年的脱落率为19%，2年的脱落率为33.3%，对照组治疗效果明显优于对照组，观察组治疗效果明显优于对照组，结论：小儿乳磨牙大面积龋坏时，预成冠的修复有利于患者恢复正常的解剖外形和咬合关系，促进颌骨的正常发育。

值得在临床上广泛地推广和应用。

【关键词】乳磨牙；预成冠；树脂；临床评价【中图分类号】R783 【文献标识码】A 【文章编号】1007-8231（2016）27-0173-02儿童乳牙预成冠（PMC）是一个预先成型的、与牙齿非常贴合的牙冠，其主要功能为保护牙齿，防止牙齿的劈裂，并同时加强牙齿的强度、有效保护缺损较大的乳磨牙至替牙期，从而保证继承恒牙顺利萌出。

恢复患患儿的正常咬合关系等优点。

我国是小儿龋病的高发时期，5岁的患龋率为高达66.55%，其因素多为乳牙的解剖形态特点和饮食习惯有很大的关系，另外小儿的自洁效果相对较差，在充填治疗中患儿的远期的充填效果较差，脱离率极高。

针对以上情况我院门诊儿牙收治了42例小儿牙体缺损的患者作为作为研究对象，利于预成冠修复取得了满意的效果，具体案列分析如下。

1.资料与方法1.1 一般资料本文案例选取了我院儿牙科42例大面积龋坏的患者，男20例，女22例，年龄在4～7岁之间，平均为5.9岁，其中，第一乳磨牙为22例，第二乳磨牙为20例。

42例患儿均为邻面龋，MO为12例，MOD为18例，DO为12例。
