【摘要】：目的： 本文以病例報(bào)道的形式探討單支銼Reciproc鎳鈦旋轉(zhuǎn)器械在根管治療下頜第一磨牙根管系統(tǒng)中療效評(píng)價(jià)。 方法： 收集下頜第一磨牙患急，慢性牙髓炎及牙髓壞死，急性根尖周炎的臨床病例10例，拍攝術(shù)前X線片，確認(rèn)根管系統(tǒng)由MB、ML、D三個(gè)根管組成。常規(guī)制備開(kāi)髓洞型，并使用小球鉆去除覆蓋在根管口的牙本質(zhì)懸突，使髓室底完全暴露，建立器械進(jìn)入根管的冠方直線通道。常規(guī)拔髓、清理髓腔。沖洗髓腔，吹干使髓室底視野清晰。術(shù)中使用DG16根管口探針探查根管口，使用10#、15#C銼疏通根管，ROOT ZX根管長(zhǎng)度定位儀結(jié)合X線片確定根管內(nèi)工作長(zhǎng)度，17%乙二胺四乙酸（EDTA）凝膠結(jié)合單支Reciproc銼鎳鈦旋轉(zhuǎn)器械進(jìn)行根管預(yù)備，，預(yù)備時(shí)采用上下提拉式預(yù)備根管；提拉幅度不要超過(guò)3mm；提拉次數(shù)不超過(guò)3次；預(yù)備時(shí)不要產(chǎn)生根向壓力。2%氯己定+3%過(guò)氧化氫+0.9%氯化鈉交替沖洗根管，使用P5超聲蕩洗清理根管預(yù)備過(guò)程中產(chǎn)生的牙本質(zhì)碎屑及沾污。干燥根管后根管內(nèi)導(dǎo)入氫氧化鈣糊劑，一周后復(fù)診。患者復(fù)診時(shí)無(wú)癥狀采用熱牙膠連續(xù)波垂直加壓技術(shù)充填根管。拍攝術(shù)后X線片，評(píng)價(jià)其療效。 結(jié)果： 在收集的10例下頜第一磨牙臨床病例全部探通。經(jīng)過(guò)Reciproc銼進(jìn)行根管預(yù)備后并充填，所有患牙均得到很好的治療效果。 結(jié)論： Reciproc銼作為單根銼，在牙髓炎、牙髓壞死及根尖周炎等病例中均可以安全有效的進(jìn)行根管預(yù)備。下頜第一磨牙由于存在多種根管數(shù)目及復(fù)雜的根管形態(tài)，增加了在臨床中進(jìn)行根管治療難度，使用Reciproc銼鎳鈦旋轉(zhuǎn)器械結(jié)合EDTA凝膠預(yù)備根管，同時(shí)應(yīng)用2%氯已啶溶液沖洗根管及嚴(yán)密充填根管，可以獲得下頜第一磨牙良好的根管治療效果。
[Abstract]:Objective:. A case study was conducted to evaluate the efficacy of single file Reciproc nickel titanium rotary instrument in the treatment of mandibular first molar root canal system. Methods:. Ten clinical cases of acute, chronic pulpitis, pulp necrosis and acute periapical periodontitis of the first molar of the mandible were collected. X-ray films were taken before operation to confirm that the root canal system was composed of three root canals of MBN MLD. The dentine suspensions covered in the root canal were removed with a small ball drill, and the pulp chamber floor was completely exposed. A coronal straight passage of the instrument into the root canal was established, and the pulp cavities were routinely pulled out, the pulp cavities were cleaned, and the pulp cavities were flushed. DG16 root canal probe was used to explore the root canal orifice. The working length of root canal was determined by using 10 #C file and root ZX root canal length locator combined with X ray slice to determine the working length of root canal. The preparation of root canal was performed with 17% ethylenediamine tetraacetic acid (EDTA) gel combined with single Reciproc file nickel titanium rotary instrument, and the root canal was prepared with upper and lower lifting type. No more than 3 mm in range of Czochralski; no more than 3 times of pulling; do not produce root pressure of .2% chlorhexidine 3% hydrogen peroxide 0.9% sodium chloride alternately flushing root canal during preparation, Using P5 ultrasonic wash cleaning root canal preparation process produced by dentin debris and contamination. Dry root canal back root canal introduction of calcium hydroxide paste, A week later, the patients were treated with continuous wave vertical compression of hot gum to fill the root canal. X ray film was taken after operation to evaluate the curative effect. Results:. All the 10 cases of mandibular first molar were treated with Reciproc file after root canal preparation and filling. Conclusion:. As a single file, Reciproc file can be used to prepare root canal safely and effectively in pulpitis, pulp necrosis and periapical periodontitis. It increased the difficulty of root canal therapy in clinic. The root canal was prepared with Reciproc file nickel titanium rotary instrument combined with EDTA gel. The root canal was washed with 2% chlorhexidine solution and the root canal was filled tightly. Good root canal therapy can be obtained for mandibular first molar.
