摘要
目的探讨口腔暂封材料ZO(E氧化锌丁香油酚粘固剂)、Coltosa(l康特)、牙胶、Cavit G(3M)、Cimavi(t碧兰)在牙髓治疗中的应用。方法选取近期拔除的在4℃保存的30颗牙冠完整、根尖孔发育完全的离体磨牙或前磨牙(均来自北京市崇文口腔医院治疗的26例牙髓病患者),所选研究对象均排除了龋齿、牙面磨损及隐裂,钻孔打开所有牙齿的髓腔,拔髓,分别制作洞型和髓腔通路,确保洞缘1mm外由牙面封闭。所有研究对象随机分为6组,每组5颗,一组作为空白对照,髓洞不充填材料,其它5组分别填充上述材料。各个填充好的牙齿置于2%亚甲基兰染料中,纵剖牙齿并观察染料沿着洞壁和填充材料之间的空隙渗入的深度并分析各组间的差异。结果 5组经ZOE、Coltosal、牙胶、Gavit G、Cimavit等5种材料填充的标本,经染料浸泡后染液渗入情况比较,Hc=42.40,P<0.05,提示5种口腔暂封材料运用于牙髓腔的封闭效果及发生微渗的总体分布不同。经统计学分析,各组之间两两比较,可发现经渗入情况由低到高依次为牙胶;ZOE;Coltosal、Cavit_G、Cimavit。结论 Cavit_G、Cimavit等2种口腔暂封材料的渗入较少,暂封效果好,值得临床上推广应用。
Objective To discuss the application of the oral sealing materials ZOE（zinc oxide eugenol cementation agent）,Coltosal（kt）,tooth glue,Cavit G（3 M）,Cimavit（Bess LAN） in the treatment of dental pulp.Methods Select 30 recent pulled out tooth keeping in 4 ℃ which dental crown complete,fully develop from the body of the molar or premolar teeth（were from 26 cases dental pulp patients in our hospital）,the selected participants ruled out dental caries,tooth surface wear and tear of Cain,cracked open all drilling teeth of the medullary cavity,pull out pulp,were making holes type and pulp cavity pathways,ensure that hole 1 mm margin closed by the tooth surface.All subjects randomly divided into six groups,and each group had 5 star,a group as blank control,pulp hole were not filled with materials,and other 5 groups were filled with the materials.Each filling teeth was put in 2% dye methylene aram,longitudinal cutting teeth and observed the infiltration depth of the dye materials between the cave walls and along filled the space and analysis the difference among each group.Results The specimens of 5 groups filled five kinds of materials including the Coltosal,ZOE,tooth glue,Gavit G,Cimavit,compared the dye after soaking liquid into the situation,Hc = 42.40,P 0.05,tip the closed effect and the general distribution happened permeability with 5 kinds of oral temporary sealing materials used in dental pulp cavity was different.The statistical analysis,comparison between two groups,had found the infiltration condition from low to high in order as the tooth glue;ZOE;Coltosal,Cavit_G,Cimavit.Conclusion Cavit_G,Cimavit oral temporary sealing materials was less permeated,temporary sealing effect was good,and was worth to clinical application.
