蓋髓材料 Dycal.doc

蓋髓材料: Dycal本貼收到6朵鮮花用于蓋髓的材料主要是氫氧化鈣制劑。登士柏公司的產(chǎn)品有Dycal,Prisma Dycal VLC(光固化型), 當(dāng)然，最好的直接蓋髓的材料是ProRoot MTA。國(guó)內(nèi)市場(chǎng)目前只有自凝的Dycal。 在這里對(duì)Dycal作一介紹 Dycal說(shuō)明書下載：http:/www.dentsply.co.uk/msds_cosh/downloads/dycal.pdfDIRECTIONS FORDycal? Radiopaque Calcium Hydroxide CompositionCaution:U.S. Federal Law Restricts This Device To Sale By Or On The Order Of A Dentist.DYCAL? calcium hydroxide composition is a rigid, self-setting material useful in pulp capping and as a protective base-liner under dental filling materials, cements, and other base materials. It will not inhibit the polymerization of acrylic and composite restorations.使用說(shuō)明產(chǎn)品全名：Dycal 放射線阻射氫氧化鈣復(fù)合物 注意事項(xiàng)：Dycal 氫氧化鈣復(fù)合物是一種堅(jiān)硬的、自凝材料，主要用于蓋髓和保護(hù)性墊底，置于各種牙科充填材料、水門汀、或其它墊底材料下層。它不會(huì)抑制丙烯酸樹脂和其它復(fù)合修復(fù)材料的聚合。PROTECTIVE ACTIONS - It serves as a protective barrier between the dentin and pulp and acid containing cements and restorative materials. It may be used as a pulp capping agent.保護(hù)作用：它作為保護(hù)屏障，把牙本質(zhì)和牙髓與含酸性成分的水門汀和修復(fù)材料隔離開來(lái)，起到保護(hù)作用。Dycal可被用作蓋髓劑。 DIRECTIONS - Dispense equal volume (1.17 to 1.00 by wt.) of base and catalyst paste on the parchment paper pad provided. Stir immediately using a DYCAL? applicator. Stir or mix thoroughly until a uniform color is achieved.使用方法：從軟管中擠出等體積的基底糊劑和催化劑（質(zhì)量1.17克：1.00克）于調(diào)板（隨產(chǎn)品一并提供）上，立即用Dycal涂藥器進(jìn)行調(diào)拌，直至顏色均勻一致。不要過度攪拌。通常情況下，為提供最大的工作時(shí)間，您需要在10秒中內(nèi)完成調(diào)拌。Do not overspatulate. As a general rule, to provide maximum working time, you should complete mixing of the two pastes within 10 seconds. Then by quickly applying the mixed material into the cavity you take advantage of the essential flowability of the mass for efficient placement before setting starts. The cavity preparation should be dry.Do not attempt to control setting time by increasing or decreasing the amount of catalyst dispensed.The product is regulated to provide a constant working time in spite of such variations.接著迅速將調(diào)好的材料放放已備好的窩洞中，在材料開始凝固前，它具有很好的流動(dòng)性，使您能將其方便地放置至目標(biāo)位置。窩洞應(yīng)保持干燥。不要試圖通過增加或減少催化劑的用量來(lái)控制產(chǎn)品的凝固時(shí)間。本品已經(jīng)過適當(dāng)調(diào)節(jié)，能提供恒定的工作時(shí)間而不受催化劑多少的影響。翻譯和編輯：楊二The ball-pointed instrument is an effective applicator for placing the mix in the cavity and spreading it over the floor to the desired depth.將混合料放置于窩洞中并在期望的深度上進(jìn)行鋪展時(shí)，球形尖端工具（如Dycal涂藥器）是最有效的工具。Avoid touching the margins of the cavity and avoid placing a large bulk of material.避免接觸制洞的邊緣。避免置入過多材料。The mixed material will set in 2-3 minutes on the mixing pad under normal room conditions (70oF with 50% relative humidity). The set time is shorter in the mouth due to moisture and temperature.Remove any excess from retention areas or margins with a sharp spoon excavator or bur. 調(diào)好的材料在室內(nèi)（溫度：23，相對(duì)濕度：50%）條件下，通常會(huì)在2到3分鐘內(nèi)凝固。由于濕度和溫度的影響，其在口內(nèi)的凝固時(shí)間要短一些。用銳匙挖器或球鉆除去固位區(qū)或邊緣的多余材料。PRECAUTIONS - The solubility and essentially basic nature of the DYCAL? composition requires that it be used only in situations where it can be protected adequately from the intraoral environment.小心：需要在與口內(nèi)環(huán)境充分隔離的條件下，Dycal的溶解性和基本特性才能充分發(fā)揮。After the DYCAL? has completely set, use cavity varnish under amalgam restorations. 在Dycal 完全凝固后，如用銀汞合金充填，需要涂布洞襯劑后再進(jìn)行充填。It should not be used as a temporary filling or luting cement.Dycal 不能用作暫時(shí)充填材料或封閉水門汀。Studies have shown it to be adequately strong to resist the packing pressures upon amalgams during placement by usual procedures. Avoid use of excessively small pluggers and/or high packing pressures which might cause fracture of the material. It should be covered by a rigid cement base prior to condensation of gold foil restorations. The correct ratio and complete mixing of base and catalyst components are important factors affecting the radiopacity, strength, and durability of the material. 研究表明，在通常的銀汞充填過程中，Dycal的強(qiáng)度足以對(duì)抗充填壓力。過細(xì)的充填器和過高的充填壓力會(huì)導(dǎo)致材料斷裂，因此應(yīng)注意避免。在用銀汞合金加壓充填前，需要在使用Dycal 后，墊一層堅(jiān)硬的水門汀墊底材料。正確的基礎(chǔ)材料和催化劑的比例和充分的調(diào)拌很重要，會(huì)影響到材料的X線阻射性能、強(qiáng)度、耐磨性能。Greater concentrations of catalyst provide additional quantities of calycium hydroxide but adversely affect radiopacity and strength. Deliberate departures from the recommended ratio of base to catalyst are therefore to be avoided. Tooth size, shape, dentinal radiopacity and exposure conditions are additional variables which affect the ability to radiographically detect the material. 加入更多的催化劑能提供更多的氫氧化鈣，但也會(huì)影響到材料的X線阻射性能筆強(qiáng)度。因此，應(yīng)避免刻意的改變基礎(chǔ)糊劑和催化劑的比例。牙齒的大小、形態(tài)、牙本質(zhì)的X線阻射性能和曝光條件是另外一些影響材料的X線阻射性能的變量。PACKAGING - DYCAL? Base and Catalyst pastes are supplied in collapsible tin tubes equipped with an integral plastic spout and nozzle. Storing the tubes near mercury may cause amalgamation and pinholing of the tubes.包裝：一盒有基礎(chǔ)糊劑和催化劑各一支，分別為3g和1g(體積一樣)。避免把與汞一起存放，會(huì)導(dǎo)致“汞齊化”，并導(dǎo)致管壁穿孔。STORAGE AND USE CONDITION - Store at normal room temperature or below. Separation of solid and liquid phases of the base component is accelerated at elevated temperatures. Maximum shelf life is attained when stored at reduced temperatures, in a refrigerator. Allow the material to return to normal room termperature before using.Work time and set time are influenced by humidity and temperature changes. Increased humidity and elevated temperature will reduce available
